Schizophrenia ( or ) is a mental disorder characterized by a disintegration of thought processes and of emotional responsiveness. It most commonly manifests as auditory hallucinations, paranoid or bizarre delusions, or disorganized speech and thinking, and it is accompanied by significant social or occupational dysfunction. The onset of symptoms typically occurs in young adulthood, with a global lifetime prevalence of about 0.3–0.7%. Diagnosis is based on observed behavior and the patient's reported experiences.

Genetics, early environment, neurobiology, and psychological and social processes appear to be important contributory factors; some recreational and prescription drugs appear to cause or worsen symptoms. Current research is focused on the role of neurobiology, although no single isolated organic cause has been found. The many possible combinations of symptoms have triggered debate about whether the diagnosis represents a single disorder or a number of discrete syndromes. Despite the etymology of the term from the Greek roots ''skhizein'' (''σχίζειν'', "to split") and ''phrēn, phren-'' (''φρήν, φρεν-''; "mind"), schizophrenia does not imply a "split mind" and it is not the same as dissociative identity disorder—also known as "multiple personality disorder" or "split personality"—a condition with which it is often confused in public perception.

The mainstay of treatment is antipsychotic medication, which primarily suppresses dopamine, and sometimes serotonin, receptor activity. Psychotherapy and vocational and social rehabilitation are also important in treatment. In more serious cases—where there is risk to self and others—involuntary hospitalization may be necessary, although hospital stays are now shorter and less frequent than they were.

The disorder is thought mainly to affect cognition, but it also usually contributes to chronic problems with behavior and emotion. People with schizophrenia are likely to have additional (comorbid) conditions, including major depression and anxiety disorders; the lifetime occurrence of substance abuse is almost 50%. Social problems, such as long-term unemployment, poverty and homelessness, are common. The average life expectancy of people with the disorder is 12 to 15 years less than those without, the result of increased physical health problems and a higher suicide rate (about 5%).

Signs and symptoms

A person diagnosed with schizophrenia may experience hallucinations (most reported are hearing voices), delusions (often bizarre or persecutory in nature), and disorganized thinking and speech. The latter may range from loss of train of thought, to sentences only loosely connected in meaning, to incoherence known as word salad in severe cases. Social withdrawal, sloppiness of dress and hygiene, and loss of motivation and judgement are all common in schizophrenia. There is often an observable pattern of emotional difficulty, for example lack of responsiveness. Impairment in social cognition is associated with schizophrenia, as are symptoms of paranoia; social isolation commonly occurs. In one uncommon subtype, the person may be largely mute, remain motionless in bizarre postures, or exhibit purposeless agitation, all signs of catatonia.

Late adolescence and early adulthood are peak periods for the onset of schizophrenia, critical years in a young adult's social and vocational development. In 40% of men and 23% of women diagnosed with schizophrenia the condition manifested itself before the age of 19. To minimize the developmental disruption associated with schizophrenia, much work has recently been done to identify and treat the prodromal (pre-onset) phase of the illness, which has been detected up to 30 months before the onset of symptoms. Those who go on to develop schizophrenia may experience transient or self-limiting psychotic symptoms and the non-specific symptoms of social withdrawal, irritability, dysphoria, and clumsiness during the prodromal phase.

Schneiderian classification

The psychiatrist Kurt Schneider (1887–1967) listed the forms of psychotic symptoms that he thought distinguished schizophrenia from other psychotic disorders. These are called ''first-rank symptoms'' or Schneider's first-rank symptoms, and they include delusions of being controlled by an external force; the belief that thoughts are being inserted into or withdrawn from one's conscious mind; the belief that one's thoughts are being broadcast to other people; and hearing hallucinatory voices that comment on one's thoughts or actions or that have a conversation with other hallucinated voices. Although they have significantly contributed to the current diagnostic criteria, the specificity of first-rank symptoms has been questioned. A review of the diagnostic studies conducted between 1970 and 2005 found that they allow neither a reconfirmation nor a rejection of Schneider's claims, and suggested that first-rank symptoms be de-emphasized in future revisions of diagnostic systems.

Positive and negative symptoms

Schizophrenia is often described in terms of positive and negative (or deficit) symptoms. Positive symptoms are those that most individuals do not normally experience but are present in people with schizophrenia. They can include delusions, disordered thoughts and speech, and tactile, auditory, visual, olfactory and gustatory hallucinations, typically regarded as manifestations of psychosis. Hallucinations are also typically related to the content of the delusional theme. Positive symptoms generally respond well to medication. Negative symptoms are deficits of normal emotional responses or of other thought processes, and respond less well to medication. They commonly include flat or blunted affect and emotion, poverty of speech (alogia), inability to experience pleasure (anhedonia), lack of desire to form relationships (asociality), and lack of motivation (avolition). Research suggests that negative symptoms contribute more to poor quality of life, functional disability, and the burden on others than do positive symptoms. People with prominent negative symptoms often have a history of poor adjustment before the onset of illness, and response to medication is often limited.

Causes

A combination of genetic and environmental factors play a role in the development of schizophrenia. People with a family history of schizophrenia who suffer a transient or self-limiting psychosis have a 20–40% chance of being diagnosed one year later.

Genetic

Estimates of heritability vary because of the difficulty in separating the effects of genetics and the environment. The greatest risk for developing schizophrenia is having a first-degree relative with the disease (risk is 6.5%); more than 40% of monozygotic twins of those with schizophrenia are also affected. It is likely that many genes are involved, each of small effect. Many possible candidates have been proposed, including specific copy number variations, NOTCH4 and histone protein loci. A number of genome-wide associations such as zinc finger protein 804A have also been linked. There appears to be significant overlap in the genetics of schizophrenia and bipolar disorder.

Assuming a hereditary basis, one question from evolutionary psychology is why genes that increase the likelihood of psychosis evolved, assuming the condition would have been maladaptive from an evolutionary point of view. One theory implicates genes involved in the evolution of language and human nature, but so far all theories have been disproved or remain unsubstantiated.

Environment

Environmental factors associated with the development of schizophrenia include the living environment, drug use and prenatal stressors. Parenting style seems to have no effect, although people with supportive parents do better than those with critical parents. Living in an urban environment during childhood or as an adult has consistently been found to increase the risk of schizophrenia by a factor of two, even after taking into account drug use, ethnic group, and size of social group. Other factors that play an important role include social isolation and immigration related to social adversity, racial discrimination, family dysfunction, unemployment, and poor housing conditions. Childhood experiences of abuse or trauma are risk factors for a diagnosis of schizophrenia later in life.

Substance abuse

A number of drugs have been associated with the development of schizophrenia, including cannabis, cocaine, and amphetamines. About half of those with schizophrenia use drugs and/or alcohol excessively. The role of cannabis could be causal, but other drugs may be used only as coping mechanisms to deal with depression, anxiety, boredom, and loneliness.

Cannabis is associated with a dose-dependent increase in the risk of developing a psychotic disorder. Frequent use has been found to double the risk of psychosis and schizophrenia; however the causality of this link has been questioned, and it remains controversial. Amphetamine, cocaine, and to a lesser extent alcohol, can result in psychosis that presents very similarly to schizophrenia. Although not generally believed to be a cause of schizophrenia, schizophrenics as a group use nicotine at much greater rates than the general population.

Prenatal

Factors such as hypoxia and infection, or stress and malnutrition in the mother during fetal development, may result in a slight increase in the risk of schizophrenia later in life. People diagnosed with schizophrenia are more likely to have been born in winter or spring (at least in the northern hemisphere), which may be a result of increased rates of viral exposures in utero. This difference is about 5 to 8%.

Mechanisms

A number of attempts have been made to explain the link between altered brain function and schizophrenia. One of the most common is the dopamine hypothesis, which attributes psychosis to the mind's faulty interpretation of the misfiring of dopaminergic neurons.

Psychological

Many psychological mechanisms have been implicated in the development and maintenance of schizophrenia. Cognitive biases have been identified in those with the diagnosis or those at risk, especially when under stress or in confusing situations. Some cognitive features may reflect global neurocognitive deficits such as memory loss, while others may be related to particular issues and experiences.

Despite a demonstrated appearance of "blunted affect", recent findings indicate that many individuals diagnosed with schizophrenia are emotionally responsive, particularly to stressful or negative stimuli, and that such sensitivity may cause vulnerability to symptoms or to the disorder. Some evidence suggests that the content of delusional beliefs and psychotic experiences can reflect emotional causes of the disorder, and that how a person interprets such experiences can influence symptomatology. The use of "safety behaviors" to avoid imagined threats may contribute to the chronicity of delusions. Further evidence for the role of psychological mechanisms comes from the effects of psychotherapies on symptoms of schizophrenia.

Neurological

Those with a diagnosis of schizophrenia have changes in both brain structure and chemistry. Studies using neuropsychological tests and brain imaging technologies such as fMRI and PET to examine functional differences in brain activity have shown that differences seem to most commonly occur in the frontal lobes, hippocampus and temporal lobes. Reductions in brain volume, smaller than those found in Alzheimer's disease, have been reported in areas of the frontal cortex and temporal lobes. It is uncertain whether these volumetric changes are progressive or preexist prior to the onset of the disease. These differences have been linked to the neurocognitive deficits often associated with schizophrenia. Because neural circuits are altered, it has alternatively been suggested that schizophrenia should be thought of as a collection of neurodevelopmental disorders.

Particular attention has been paid to the function of dopamine in the mesolimbic pathway of the brain. This focus largely resulted from the accidental finding that phenothiazine drugs, which block dopamine function, could reduce psychotic symptoms. It is also supported by the fact that amphetamines, which trigger the release of dopamine, may exacerbate the psychotic symptoms in schizophrenia. The influential dopamine hypothesis of schizophrenia proposed that excessive activation of D₂ receptors was the cause of (the positive symptoms of) schizophrenia. Although postulated for about 20 years based on the D₂ blockade effect common to all antipsychotics, it was not until the mid-1990s that PET and SPET imaging studies provided supporting evidence. The dopamine hypothesis is now thought to be simplistic, partly because newer antipsychotic medication (atypical antipsychotic medication) can be just as effective as older medication (typical antipsychotic medication), but also affects serotonin function and may have slightly less of a dopamine blocking effect.

Interest has also focused on the neurotransmitter glutamate and the reduced function of the NMDA glutamate receptor in schizophrenia, largely because of the abnormally low levels of glutamate receptors found in the postmortem brains of those diagnosed with schizophrenia, and the discovery that glutamate-blocking drugs such as phencyclidine and ketamine can mimic the symptoms and cognitive problems associated with the condition. Reduced glutamate function is linked to poor performance on tests requiring frontal lobe and hippocampal function, and glutamate can affect dopamine function, both of which have been implicated in schizophrenia, have suggested an important mediating (and possibly causal) role of glutamate pathways in the condition. But positive symptoms fail to respond to glutamatergic medication.

Diagnosis

Schizophrenia is diagnosed based on criteria in either the American Psychiatric Association's ''Diagnostic and Statistical Manual of Mental Disorders'', version DSM-IV-TR, or the World Health Organization's International Statistical Classification of Diseases and Related Health Problems, the ICD-10. These criteria use the self-reported experiences of the person and reported abnormalities in behavior, followed by a clinical assessment by a mental health professional. Symptoms associated with schizophrenia occur along a continuum in the population and must reach a certain severity before a diagnosis is made. As of 2009 there is no objective test.

Criteria

The ICD-10 criteria are typically used in European countries, while the DSM-IV-TR criteria are used in the United States and the rest of the world, and are prevailing in research studies. The ICD-10 criteria put more emphasis on Schneiderian first-rank symptoms. In practice, agreement between the two systems is high.

According to the revised fourth edition of the ''Diagnostic and Statistical Manual of Mental Disorders'' (DSM-IV-TR), to be diagnosed with schizophrenia, three diagnostic criteria must be met: # Characteristic symptoms: Two or more of the following, each present for much of the time during a one-month period (or less, if symptoms remitted with treatment). #* Delusions #* Hallucinations #* Disorganized speech, which is a manifestation of formal thought disorder #* Grossly disorganized behavior (e.g. dressing inappropriately, crying frequently) or catatonic behavior #* Negative symptoms: Blunted affect (lack or decline in emotional response), alogia (lack or decline in speech), or avolition (lack or decline in motivation) #:If the delusions are judged to be bizarre, or hallucinations consist of hearing one voice participating in a running commentary of the patient's actions or of hearing two or more voices conversing with each other, only that symptom is required above. The speech disorganization criterion is only met if it is severe enough to substantially impair communication. # Social or occupational dysfunction: For a significant portion of the time since the onset of the disturbance, one or more major areas of functioning such as work, interpersonal relations, or self-care, are markedly below the level achieved prior to the onset. # Significant duration: Continuous signs of the disturbance persist for at least six months. This six-month period must include at least one month of symptoms (or less, if symptoms remitted with treatment).

If signs of disturbance are present for more than a month but less than six months, the diagnosis of schizophreniform disorder is applied. Psychotic symptoms lasting less than a month may be diagnosed as brief psychotic disorder, and various conditions may be classed as psychotic disorder not otherwise specified. Schizophrenia cannot be diagnosed if symptoms of mood disorder are substantially present (although schizoaffective disorder could be diagnosed), or if symptoms of pervasive developmental disorder are present unless prominent delusions or hallucinations are also present, or if the symptoms are the direct physiological result of a general medical condition or a substance, such as abuse of a drug or medication.

Subtypes

The DSM-IV-TR contains five sub-classifications of schizophrenia, although the developers of DSM-5 are recommending they be dropped from the new classification:

Paranoid type: Delusions or auditory hallucinations are present, but thought disorder, disorganized behavior, or affective flattening are not. Delusions are persecutory and/or grandiose, but in addition to these, other themes such as jealousy, religiosity, or somatization may also be present. (DSM code 295.3/ICD code F20.0)

Disorganized type: Named ''hebephrenic schizophrenia'' in the ICD. Where thought disorder and flat affect are present together. (DSM code 295.1/ICD code F20.1)

Catatonic type: The subject may be almost immobile or exhibit agitated, purposeless movement. Symptoms can include catatonic stupor and waxy flexibility. (DSM code 295.2/ICD code F20.2)

Undifferentiated type: Psychotic symptoms are present but the criteria for paranoid, disorganized, or catatonic types have not been met. (DSM code 295.9/ICD code F20.3)

Residual type: Where positive symptoms are present at a low intensity only. (DSM code 295.6/ICD code F20.5)

The ICD-10 defines two additional subtypes:

Post-schizophrenic depression: A depressive episode arising in the aftermath of a schizophrenic illness where some low-level schizophrenic symptoms may still be present. (ICD code F20.4)

Simple schizophrenia: Insidious and progressive development of prominent negative symptoms with no history of psychotic episodes. (ICD code F20.6)

Differential

Psychotic symptoms may be present in several other mental disorders, including bipolar disorder, borderline personality disorder, drug intoxication and drug-induced psychosis. Delusions ("non-bizarre") are also present in delusional disorder, and social withdrawal in social anxiety disorder, avoidant personality disorder and schizotypal personality disorder. Schizophrenia is comorbid with obsessive-compulsive disorder (OCD) considerably more often than could be explained by pure chance, although it can be difficult to distinguish obsessions that occur in OCD from the delusions of schizophrenia.

A more general medical and neurological examination may be needed to rule out medical illnesses which may rarely produce psychotic schizophrenia-like symptoms, such as metabolic disturbance, systemic infection, syphilis, HIV infection, epilepsy, and brain lesions. It may be necessary to rule out a delirium, which can be distinguished by visual hallucinations, acute onset and fluctuating level of consciousness, and indicates an underlying medical illness. Investigations are not generally repeated for relapse unless there is a specific ''medical'' indication or possible adverse effects from antipsychotic medication.

Prevention

Evidence for the effectiveness of early intervention is inconclusive. While there is some evidence that early intervention in those with a psychotic episode may improve short term outcomes, there is little benefit from these measures after five years. Attempting to prevent schizophrenia in the prodrome phase is of uncertain benefit and therefore as of 2009 is not recommended. Prevention is difficult as there are no reliable markers for the later development of the disease.

Management

The primary treatment of schizophrenia is antipsychotic medications, often in combination with psychological and social supports. Hospitalization may occur for severe episodes either voluntarily or (if mental health legislation allows it) involuntarily. Long-term hospitalization is uncommon since deinstitutionalization beginning in the 1950s, although still occurs. Community support services including drop-in centers, visits by members of a community mental health team, supported employment and support groups are common. Some evidence indicates that regular exercise has a positive effect on the physical and mental health of those with schizophrenia.

Medication

The first-line psychiatric treatment for schizophrenia is antipsychotic medication, which can reduce the positive symptoms of psychosis in about 7–14 days. Antipsychotics however fail to significantly ameliorate the negative symptoms and cognitive dysfunction.

The choice of which antipsychotic to use is based on benefits, risks, and costs. It is debatable whether, as a class, typical or atypical antipsychotics are better. Both have equal drop-out and symptom relapse rates when typicals are used at low to moderate dosages. There is a good response in 40–50%, a partial response in 30–40%, and treatment resistance (failure of symptoms to respond satisfactorily after six weeks to two of three different antipsychotics) in 20% of people. Clozapine is an effective treatment for those who respond poorly to other drugs, but it has the potentially serious side effect of agranulocytosis (lowered white blood cell count) in 1–4%.

With respect to side effects typical antipsychotics are associated with a higher rate of extrapyramidal side effects while atypicals are associated with considerable weight gain, diabetes and risk of metabolic syndrome. While atypicals have fewer extrapyramidal side effects these differences are modest. Some atypicals such as quetiapine and risperidone are associated with a higher risk of death compared to the atypical perphenazine, while clozapine is associated with the lowest risk of death. It remains unclear whether the newer antipsychotics reduce the chances of developing neuroleptic malignant syndrome, a rare but serious neurological disorder.

For people who are unwilling or unable to take medication regularly, long-acting depot preparations of antipsychotics may be used to achieve control. When used in combination with psychosocial interventions they may improve long-term adherence to treatment.

Psychosocial

A number of psychosocial interventions may be useful in the treatment of schizophrenia including: family therapy, assertive community treatment, supported employment, cognitive remediation, skills training, cognitive behavioral therapy (CBT), token economic interventions, and psychosocial interventions for substance use and weight management. Family therapy or education, which addresses the whole family system of an individual, may reduce relapses and hospitalizations. The evidence for CBT's effectiveness in either reducing symptoms or preventing relapse is minimal. Art or drama therapy have not been well-researched.

Prognosis

Schizophrenia has great human and economic costs. It results in a decreased life expectancy of 12–15 years, primarily because of its association with obesity, sedentary lifestyles, and smoking, with an increased rate of suicide playing a lesser role. These differences in life expectancy increased between the 1970s and 1990s, and between the 1990s and first decade of the 21st century did not change substantially in a health system with open access to care (Finland).

Schizophrenia is a major cause of disability, with active psychosis ranked as the third-most-disabling condition after quadriplegia and dementia and ahead of paraplegia and blindness. Approximately three-fourths of people with schizophrenia have ongoing disability with relapses. Some people do recover completely and others function well in society. Most people with schizophrenia live independently with community support. In people with a first episode of psychosis a good long-term outcome occurs in 42%, an intermediate outcome in 35% and a poor outcome in 27%. Outcomes for schizophrenia appear better in the developing than the developed world. These conclusions however have been questioned.

There is a higher than average suicide rate associated with schizophrenia. This has been cited at 10%, but a more recent analysis of studies and statistics revises the estimate to 4.9%, most often occurring in the period following onset or first hospital admission. Several times more (20 to 40%) attempt suicide at least once. There are a variety of risk factors, including male gender, depression, and a high intelligence quotient.

Schizophrenia and smoking have shown a strong association in studies world-wide. Use of cigarettes is especially high in individuals diagnosed with schizophrenia, with estimates ranging from 80% to 90% being regular smokers, as compared to 20% of the general population. Those who smoke tend to smoke heavily, and additionally smoke cigarettes with high nicotine content.

Some evidence suggests that paranoid schizophrenia may have a better prospect than other types of schizophrenia for independent living and occupational functioning.

Epidemiology

thumb|Disability-adjusted life year for schizophrenia per 100,000 inhabitants in 2004.

Schizophrenia affects around 0.3–0.7% of people at some point in their life, or 24 million people worldwide as of 2011. It occurs 1.4 times more frequently in males than females and typically appears earlier in men—the peak ages of onset are 20–28 years for males and 26–32 years for females. Onset in childhood is much rarer, as is onset in middle- or old age. Despite the received wisdom that schizophrenia occurs at similar rates worldwide, its prevalence varies across the world, within countries, and at the local and neighborhood level. It causes approximately 1% of worldwide disability adjusted life years. The rate of schizophrenia varies up to threefold depending on how it is defined.

History

Accounts of a schizophrenia-like syndrome are thought to be rare in the historical record before the 19th century, although reports of irrational, unintelligible, or uncontrolled behavior were common. A detailed case report in 1797 concerning James Tilly Matthews, and accounts by Phillipe Pinel published in 1809, are often regarded as the earliest cases of the illness in the medical and psychiatric literature. Schizophrenia was first described as a distinct syndrome affecting teenagers and young adults by Bénédict Morel in 1853, termed ''démence précoce'' (literally 'early dementia'). The term dementia praecox was used in 1891 by Arnold Pick in a case report of a psychotic disorder. In 1893 Emil Kraepelin introduced a broad new distinction in the classification of mental disorders between ''dementia praecox'' and mood disorder (termed manic depression and including both unipolar and bipolar depression). Kraepelin believed that ''dementia praecox'' was primarily a disease of the brain, and particularly a form of dementia, distinguished from other forms of dementia such as Alzheimer's disease which typically occur later in life.

The word ''schizophrenia''—which translates roughly as "splitting of the mind" and comes from the Greek roots ''schizein'' (σχίζειν, "to split") and ''phrēn'', ''phren-'' (φρήν, φρεν-, "mind")—was coined by Eugen Bleuler in 1908 and was intended to describe the separation of function between personality, thinking, memory, and perception. Bleuler described the main symptoms as 4 ''A'''s: flattened ''Affect'', ''Autism'', impaired ''Association'' of ideas and ''Ambivalence''. Bleuler realized that the illness was not a dementia, as some of his patients improved rather than deteriorated, and thus proposed the term schizophrenia instead. Treatment was revolutionized in the mid-1950s with the development and introduction of chlorpromazine. In the early 1970s, the diagnostic criteria for schizophrenia was the subject of a number of controversies which eventually led to the operational criteria used today. It became clear after the 1971 US-UK Diagnostic Study that schizophrenia was diagnosed to a far greater extent in America than in Europe. This was partly due to looser diagnostic criteria in the US, which used the DSM-II manual, contrasting with Europe and its ICD-9. David Rosenhan's 1972 study, published in the journal ''Science'' under the title "On being sane in insane places", concluded that the diagnosis of schizophrenia in the US was often subjective and unreliable. These were some of the factors leading to the revision not only of the diagnosis of schizophrenia, but the revision of the whole DSM manual, resulting in the publication of the DSM-III in 1980.

The term ''schizophrenia'' is commonly misunderstood to mean that affected persons have a "split personality". Although some people diagnosed with schizophrenia may hear voices and may experience the voices as distinct personalities, schizophrenia does not involve a person changing among distinct multiple personalities. The confusion arises in part due to the literal interpretation of Bleuler's term ''schizophrenia''. The first known misuse of the term to mean "split personality" was in an article by the poet T. S. Eliot in 1933.

Society and culture

Social stigma has been identified as a major obstacle in the recovery of patients with schizophrenia. In a large, representative sample from a 1999 study, 12.8% of Americans believed that individuals with schizophrenia were "very likely" to do something violent against others, and 48.1% said that they were "somewhat likely" to. Over 74% said that people with schizophrenia were either "not very able" or "not able at all" to make decisions concerning their treatment, and 70.2% said the same of money management decisions. The perception of individuals with psychosis as violent has more than doubled in prevalence since the 1950s, according to one meta-analysis.

In 2002 the term for schizophrenia in Japan was changed from ''Seishin-Bunretsu-Byō''　精神分裂病 (mind-split-disease) to ''Tōgō-shitchō-shō''　統合失調症 (integration disorder) to reduce stigma. The new name was inspired by the biopsychosocial model; it increased the percentage of patients who were informed of the diagnosis from 37% to 70% over three years.

In the United States, the cost of schizophrenia—including direct costs (outpatient, inpatient, drugs, and long-term care) and non-health care costs (law enforcement, reduced workplace productivity, and unemployment)—was estimated to be $62.7 billion in 2002.

The book and film ''A Beautiful Mind'' chronicle the life of John Forbes Nash, a Nobel Prize-winning mathematician who was diagnosed with schizophrenia.

Terence Kemp McKenna (November 16, 1946 – April 3, 2000) was an Irish-American researcher, philosopher, speaker, spiritual teacher and writer on many subjects; such as human consciousness, psychedelic drugs, the evolution of civilizations, the origin and the end of the universe, cybernetics, alchemy, and extraterrestrial beings.

Biography

Early life

Terence McKenna grew up in Paonia, Colorado. He was introduced to geology through his uncle and developed a hobby of solitary fossil hunting in the arroyos near his home. From this he developed a deep artistic and scientific appreciation of nature.

At age 16, Terence moved to Los Altos, California to live with family friends for a year. He finished high school in Lancaster, CA. In 1963, McKenna was introduced to the literary world of psychedelics through ''The Doors of Perception'' and ''Heaven and Hell'' by Aldous Huxley and certain issues of ''The Village Voice'' that talked about psychedelics.

Terence claimed that one of his early psychedelic experiences with morning glory seeds showed him "that there was something there worth pursuing." In an audio interview Terence Mckenna claims to have started smoking cannabis regularly during the summer following his 17th birthday.

Studying and traveling

In 1965, Terence enrolled in U.C. Berkeley to study Art History. In 1967, while in college, he got involved with shamanism after being lead there by studying Tibetan religions That year, which he called his "opium and kabbala phase," he also traveled to Jerusalem, where he met Kathleen Harrison, who would later become his wife.

In 1969, Terence traveled to Nepal lead by his "interest in Tibetan painting and hallucinogenic shamanism." During his time there, he studied the Tibetan language and worked as a hashish smuggler, until "one of his Bombay-to-Aspen shipments fell into the hands of U. S. Customs." He was forced to move to avoid capture by Interpol. He wandered through Southeast Asia viewing ruins, collected butterflies in Indonesia, and worked as an English teacher in Tokyo. He then went back to Berkeley to continue studying biology, which he called "his first love."

After he completed part of his studies and his mother's death from cancer in 1971, Terence, his brother Dennis, and three friends traveled to the Colombian Amazon in search of oo-koo-hé, a plant preparation containing DMT. Instead of oo-koo-hé they found various forms of ayahuasca, or "yagé," and gigantic psilocybe cubensis which became the new focus of the expedition. In La Chorrera, at the urging of his brother, he was the subject of a psychedelic experiment which he claimed put him in contact with Logos: an informative, divine voice he believed was universal to visionary religious experience. The voice's revelations and his brother's simultaneous peculiar experience prompted him to explore the structure of an early form of the I Ching, which led to his "Novelty Theory." During their stay in the Amazon, Terence also got romantically involved with his translator, Ev.

In 1972, Terence returned to Berkeley to finish his studies. There he decided to switch majors to a Bachelor of Science in Ecology and Conservation, in a then-new experimental section of the same university called the Tussman Experimental College. During his studies, he would also develop techniques for cultivating psilocybin mushrooms with Dennis.

In 1975, he parted with his girlfriend Ev, when she left him for one of Terence's friends from Berkeley. Their parting left him "tormented with migraines and living alone." He graduated in 1975. That same year, he began a relationship with a friend he met in Jerusalem, Kathleen.

Soon after graduating, Terence and Dennis published a book inspired by their Amazon experiences, ''The Invisible Landscape: Mind, Hallucinogens and the I Ching.'' Terence also began lecturing. The brothers' experiences in the Amazon would later play a major role in Terence's book ''True Hallucinations'', published in 1993. In 1976, the brothers published what they had learned about the cultivation of mushrooms in a book entitled ''Psilocybin - Magic Mushroom Grower's Guide'' under the pseudonyms OT Oss and ON Oeric.

Later life

In the early 1980s, McKenna began to speak publicly on the topic of psychedelic drugs, lecturing extensively and conducting weekend workshops. Though associated with the New Age and human potential movements, McKenna himself had little patience for New Age sensibilities. He repeatedly stressed the importance and primacy of felt experience, as opposed to dogma. Timothy Leary once introduced him as "one of the five or six most important people on the planet." }}He soon became a fixture of popular counterculture. His growing popularity culminated in the early to mid-1990s with the publication of several books: ''True Hallucinations'', relating the tale of his 1971 La Chorrera experience; ''Food of the Gods''; and ''The Archaic Revival''. He became a popular personality in the psychedelic rave/dance scene of the early 1990s, with frequent spoken word performances at raves and contributions to psychedelic and goa trance albums by The Shamen, Spacetime Continuum, Alien Project, Capsula, Entheogenic, Zuvuya, Shpongle, and Shakti Twins. His speeches were, and are, sampled by many. In 1994 he appeared as a speaker at the Starwood Festival, documented in the book ''Tripping'' by Charles Hayes. His lectures were produced on both cassette tape and CD.

McKenna was a colleague of chaos mathematician Ralph Abraham, and biologist Rupert Sheldrake, creator of the theory of "morphogenetic fields", not to be confused with the mainstream usage of the same term. He conducted several public debates known as ''trialogues'' with them from the late 1980s until his death. Books containing transcriptions of some of these events were published. He was also a friend and associate of Ralph Metzner, Nicole Maxwell, and Riane Eisler, participating in joint workshops and symposia with them. He was a personal friend of Tom Robbins, and influenced the thought of many scientists, writers, artists, and entertainers. His influences include comedian Bill Hicks, whose routines about psychedelic drugs drew heavily from McKenna's works. He is also the inspiration for the Twin Peaks character Dr. Jacoby.

In addition to psychedelic drugs, McKenna spoke on the subjects of virtual reality, which he saw as a way to artistically communicate the experience of psychedelics; techno-paganism; artificial intelligence; evolution; extraterrestrials; and aesthetic theory, specifically about art/visual experience as ''information'' representing the significance of hallucinatory visions experienced under the influence of psychedelics.

In 1985, McKenna co-founded Botanical Dimensions with his then-wife Kathleen, a nonprofit ethnobotanical preserve in Hawaii, where he lived for many years before he died. In 1997 he and Kathleen divorced. Before moving to Hawaii permanently, McKenna split his time between Hawaii and Occidental, located in the redwood-studded hills of Sonoma County, California.

Death

A longtime sufferer of migraines, in mid-1999 McKenna returned to his home on the big island of Hawaii after a long lecturing tour. He began to suffer from increasingly painful headaches. This culminated in three brain seizures in one night, which he claimed were the most powerful psychedelic experiences he had ever known. Upon his emergency trip to the hospital on Oahu, Terence was diagnosed with glioblastoma multiforme, a highly aggressive form of brain cancer. For the next several months he underwent various treatments, including experimental gamma knife radiation treatment. According to Wired magazine, McKenna was worried that his tumour was caused by his 35-years of smoking cannabis; though his doctors assured him there was no causal relation.

In late 1999, Erik Davis conducted what would be the last interview of McKenna. During the interview McKenna also talked about the announcement of his death:

Terence died on April 3, 2000, at the age of 53, with his loved ones at his bedside. He is survived by his brother Dennis, his son Finn, and his daughter Klea.

The library fire

On February 7, 2007, McKenna's library of rare books and personal notes was destroyed in a fire which burned offices belonging to Big Sur's Esalen Institute storing the collection. An index maintained by his brother Dennis survives, though little else.

Ideas

Terence McKenna advocated the exploration of altered states of mind via the ingestion of naturally occurring psychedelic substances. For example, and in particular, as facilitated by the ingestion of high doses of psychedelic mushrooms, and DMT, which he believed was the apotheosis of the psychedelic experience. He spoke of the "jeweled, self-dribbling basketballs" or "self-transforming machine elves" that one encounters in that state.

Although he avoided giving his allegiance to any one interpretation (part of his rejection of monotheism), he was open to the idea of psychedelics as being "trans-dimensional travel"; literally, enabling an individual to encounter what could be ancestors, or spirits of earth. He remained opposed to most forms of organized religion or guru-based forms of spiritual awakening.

Either philosophically or religiously, he expressed admiration for Marshall McLuhan, Pierre Teilhard de Chardin, Gnostic Christianity, Alfred North Whitehead and Alchemy. McKenna always regarded the Greek philosopher Heraclitus as his favorite philosopher.

He also expressed admiration for the works of James Joyce (calling ''Finnegans Wake'' "the quintessential work of art, or at least work of literature of the 20th century") and Vladimir Nabokov: McKenna once said that he would have become a Nabokov lecturer if he had never encountered psychedelics.

The "Stoned Ape" Theory of Human Evolution

In his book ''Food of the Gods'', McKenna proposed that the transformation from humans' early ancestors ''Homo erectus'' to the species ''Homo sapiens'' mainly had to do with the addition of the mushroom ''Psilocybe cubensis'' in its diet - an event which according to his theory took place in about 100,000 BC (this is when he believed that the species diverged from the Homo genus). He based his theory on the main effects, or alleged effects, produced by the mushroom. One of the effects that comes about from the ingestion of low doses, which agrees with one of scientist Roland Fischer's findings from the late 60s-early 70s, is it significantly improves the visual acuity of humans - so theoretically, of other human-like mammals too. According to McKenna, this effect would have definitely prove to be of evolutionary advantage to humans' omnivorous hunter-gatherer ancestors that would have stumbled upon it "accidentally"; as it would make it easier for them to hunt.

In higher doses, McKenna claims, the mushroom acts as a sexual stimulator, which would make it even more beneficial evolutionarily, as it would result in more offspring. At even higher doses, the mushroom would have acted to "dissolve boundaries", which would have promoted community-bonding and group sexual activities-that would result in a mixing of genes and therefore greater genetic diversity. Generally McKenna believed that the periodic ingestion of the mushroom would have acted to dissolve the ego in humans before it ever got the chance to grow in destructive proportions. In this context he likened the ego to a cancerous tumor that can grow uncontrollable and become destructive to its host. In his own words:

The mushroom, according to McKenna, had also given humans their first truly religious experiences (which, as he believed, were the basis for the foundation of all subsequent religions to date). Another factor that McKenna talked about was the mushroom's potency to promote linguistic thinking. This would have promoted vocalisation, which in turn would have acted in cleansing the brain (based on a scientific theory that vibrations from speaking cause the precipitation of impurities from the brain to the cerebrospinal fluid), which would further mutate the brain. All these factors according to McKenna were the most important factors that promoted evolution towards the ''Homo sapiens'' species. After this transformation took place, the species would have begun moving out of Africa to populate the rest of the planet Later on, this theory by McKenna was given the name "The 'Stoned Ape' Theory of Human Evolution".

Louis Wain (5 August 1860 – 4 July 1939) was an English artist best known for his drawings, which consistently featured anthropomorphised large-eyed cats and kittens. In his later years he suffered from schizophrenia, which, according to some psychologists, can be seen in his works.

Life and work

Louis William Wain was born on 5 August 1860 in Clerkenwell in London. His father was a textile trader and embroiderer; his mother was French. He was the first of six children, and the only male child. None of his five sisters ever married. At the age of thirty, his youngest sister was certified as insane, and admitted to an asylum. The remaining sisters lived with their mother for the duration of their lifetimes, as did Louis for the majority of his life.

Wain was born with a cleft lip and the doctor gave his parents the orders that he should not be sent to school or taught until he was ten years old. As a youth, he was often truant from school, and spent much of his childhood wandering around London. Following this period, Louis studied at the West London School of Art and eventually became a teacher there for a short period. At the age of 20, Wain was left to support his mother and sisters after his father's death.

Wain soon quit his teaching position to become a freelance artist, and in this role he achieved substantial success. He specialized in drawing animals and country scenes, and worked for several journals including the ''Illustrated Sporting and Dramatic News'', where he stayed for four years, and the ''Illustrated London News'', beginning in 1886. Through the 1880s, Wain's work included detailed illustrations of English country houses and estates, along with livestock he was commissioned to draw at agricultural shows. His work at this time includes a wide variety of animals, and he maintained his ability to draw creatures of all kinds throughout his lifetime. At one point, he hoped to make a living by drawing dog portraits.

At the age of 23, Wain married his sisters' governess, Emily Richardson, who was ten years his senior (which was considered quite scandalous at the time), and moved with her to Hampstead in north London. Emily soon began to suffer from cancer, and died only three years into their marriage. It was during this period that Wain discovered the subject that would define his career. During her illness, Emily was comforted by their pet cat Peter, and Wain taught him tricks such as wearing spectacles and pretending to read in order to amuse his wife. He began to draw extensive sketches of the large black and white cat. He later wrote of Peter, "To him properly belongs the foundation of my career, the developments of my initial efforts, and the establishing of my work." Peter can be recognized in many of Wain's early published works.

In 1886, Wain's first drawing of anthropomorphised cats was published in the Christmas issue of the ''Illustrated London News'', titled ''A Kittens' Christmas Party''. The illustration depicted 150 cats, many of which resemble Peter, sending invitations, holding a ball, playing games, and making speeches over eleven panels. Still, the cats remain on all fours, unclothed, and without the variety of human-like expression that would characterize Wain's work. Under the pseudonym George Henri Thompson, he illustrated numerous books for children by Clifton Bingham published by Ernest Nister.

In subsequent years, Wain's cats began to walk upright, smile broadly and use other exaggerated facial expressions, and wear sophisticated contemporary clothing. Wain's illustrations showed cats playing musical instruments, serving tea, playing cards, fishing, smoking, and enjoying a night at the opera. Such anthropomorphic portrayals of animals were very popular in Victorian England, and were often found in prints, on greeting cards and in satirical illustrations such as those of John Tenniel.

Wain was a prolific artist over the next thirty years, sometimes producing as many as several hundred drawings a year. He illustrated about one hundred children's books, and his work appeared in papers, journals, and magazines, including the ''Louis Wain Annual'', which ran from 1901 to 1915. His work was also regularly reproduced on picture postcards, and these are highly sought after by collectors today. In 1898 and 1911 he was chairman of the National Cat Club.

Wain's illustrations often parody human behavior, satirizing fads and fashions of the day. He wrote, "I take a sketch-book to a restaurant, or other public place, and draw the people in their different positions ''as cats'', getting as near to their human characteristics as possible. This gives me ''doubly'' nature, and these studies I think [to be] my best humorous work."

Wain was involved with several animal charities, including the Governing Council of Our Dumb Friends League, the Society for the Protection of Cats, and the Anti-Vivisection Society. He was also active in the National Cat Club, acting as President and Chairman of the committee at times. He felt that he helped "to wipe out the contempt in which the cat has been held" in England.

Despite his popularity, Wain suffered financial difficulty throughout his life. He remained responsible for supporting his mother and sisters, and had little business sense. Wain was modest and easily exploited, ill-equipped for bargaining in the world of publishing. He often sold his drawings outright, retaining no rights over their reproduction. He was easily misled, and occasionally found himself duped by the promise of a new invention or other money-making scheme.

He travelled to New York in 1907, where he drew some comic strips, such as ''Cats About Town'' and ''Grimalkin'', for Hearst newspapers. His work was widely admired, although his critical attitude toward the city made him the subject of sniping in the press. He returned home with even less money than before due to imprudent investment in a new type of oil lamp.

Mental disorder

From this point, Wain's popularity began to decline. He returned from New York broke, and his mother had died of Spanish influenza while he was abroad. His mental instability also began around this time, and increased gradually over the years. He had always been considered quite charming but odd, and often had difficulty in distinguishing between fact and fantasy. Others frequently found him incomprehensible, due to his way of speaking tangentially. His behavior and personality changed, and he began to suffer from delusions, with the onset of schizophrenia. Whereas he had been a mild-mannered and trusting man, he became hostile and suspicious, particularly towards his sisters. He claimed that the flickering of the cinema screen had robbed the electricity from their brains. He began wandering the streets at night, rearranging furniture within the house, and spent long periods locked in his room writing incoherently.

Some speculate that the onset of Wain's schizophrenia was precipitated by toxoplasmosis, a parasitic infection that can be contracted from cats. The theory that toxoplasmosis can trigger schizophrenia is the subject of ongoing research, though the origins of the theory can be traced back as early as 1953.

When his sisters could no longer cope with his erratic and occasionally violent behavior, he was finally committed in 1924 to a pauper ward of Springfield Mental Hospital in Tooting. A year later, he was discovered there and his circumstances were widely publicized, leading to appeals from such figures as H. G. Wells and the personal intervention of the Prime Minister. Wain was transferred to the Bethlem Royal Hospital in Southwark, and again in 1930 to Napsbury Hospital near St Albans in Hertfordshire, north of London. This hospital was relatively pleasant, with a garden and colony of cats, and he spent his final 15 years there in peace. While he became increasingly deluded, his erratic mood swings subsided, and he continued drawing for pleasure. His work from this period is marked by bright colors, flowers, and intricate and abstract patterns, though his primary subject remained the same.

Dr. Michael Fitzgerald disputes the claim of schizophrenia, indicating Wain more than likely had Asperger syndrome (AS). Of particular note, Fitzgerald indicates that while Wain's art takes on a more abstract nature as he grew older, his technique and skill as a painter did not diminish as one would expect from a schizophrenic. Moreover, elements of visual agnosia are demonstrated in his painting, a key element in some cases of AS. If Wain had visual agnosia, it may have manifested itself merely as an extreme attention to detail.

A series of five of his paintings is commonly used as an example in psychology textbooks to putatively show the change in his style as his psychological condition deteriorated. However, it is not known if these works were created in the order usually presented, as Wain did not date them. Rodney Dale, author of ''Louis Wain: The Man Who Drew Cats'', has criticised the belief that the five paintings can be used as an example of Wain's deteriorating mental health, writing: "Wain experimented with patterns and cats, and even quite late in life was still producing conventional cat pictures, perhaps 10 years after his [supposedly] 'later' productions which are patterns rather than cats."

H. G. Wells said of him, "He has made the cat his own. He invented a cat style, a cat society, a whole cat world. English cats that do not look and live like Louis Wain cats are ashamed of themselves."

His work is now highly collectible but care is needed as forgeries are common.
