"What is ALS " "ALS" redirects here. For other uses, see ALS (disambiguation). "Motor neurone disease" redirects here. For a broader group of diseases that affect motor neurons, see Motor neuron disease. Amyotrophic lateral sclerosis (ALS)—also referred to as motor neurone disease (MND), Charcot disease, and, in the United States, Lou Gehrig's disease—is a neurodegenerative disease with various causes. It is characterised by muscle spasticity, rapidly progressive weakness due to muscle atrophy, difficulty in speaking (dysarthria), swallowing (dysphagia), and breathing (dyspnea). ALS is the most common of the five motor neuron diseases. Signs and symptoms[edit] The disorder causes muscle weakness and atrophy throughout the body due to the degeneration of the upper and lower motor neurons. Individuals affected by the disorder may ultimately lose the ability to initiate and control all voluntary movement, although bladder and bowel function and the muscles responsible for eye movement are usually spared until the final stages of the disease.[1] Cognitive function is generally spared for most patients, although some (about 5%) also develop frontotemporal dementia.[2] A higher proportion of patients (30–50%) also have more subtle cognitive changes which may go unnoticed, but are revealed by detailed neuropsychological testing. Infrequently ALS coexists in individuals who also experience dementia, degenerative muscle disease, and degenerative bone disease as part of a syndrome called multisystem proteinopathy.[3] Sensory nerves and the autonomic nervous system are generally unaffected, meaning the majority of people with ALS will maintain hearing, sight, touch, smell, and taste.[4] Initial symptoms[edit] The earliest symptoms of ALS are typically obvious weakness and/or muscle atrophy. Other presenting symptoms include trouble swallowing, cramping, or stiffness of affected muscles; muscle weakness affecting an arm or a leg; and/or slurred and nasal speech. The parts of the body affected by early symptoms of ALS depend on which motor neurons in the body are damaged first. About 75% of people contracting the disease experience "limb onset" ALS, i.e., first symptoms in the arms or legs. Patients with the leg onset form may experience awkwardness when walking or running or notice that they are tripping or stumbling, often with a "dropped foot" which drags gently along the ground. Arm-onset patients may experience difficulty with tasks requiring manual dexterity such as buttoning a shirt, writing, or turning a key in a lock. Occasionally, the symptoms remain confined to one limb for a long period of time or for the whole length of the illness; this is known as monomelic amyotrophy. About 25% of cases are "bulbar onset" ALS. These patients first notice difficulty speaking clearly or swallowing. Speech may become slurred, nasal in character, or quieter. Other symptoms include difficulty swallowing and loss of tongue mobility. A smaller proportion of patients experience "respiratory onset" ALS, where the intercostal muscles that support breathing are affected first. A small proportion of patients may also present with what appears to be frontotemporal dementia, but later progresses to include more typical ALS symptoms. Over time, patients experience increasing difficulty moving, swallowing (dysphagia), and speaking or forming words (dysarthria). Symptoms of upper motor neuron involvement include tight and stiff muscles (spasticity) and exaggerated reflexes (hyperreflexia) including an overactive gag reflex. An abnormal reflex commonly called Babinski's sign also indicates upper motor neuron damage. Symptoms of lower motor neuron degeneration include muscle weakness and atrophy, muscle cramps, and fleeting twitches of muscles that can be seen under the skin (fasciculations). Around 15–45% of patients experience pseudobulbar affect, a neurological disorder also known as "emotional lability", which consists of uncontrollable laughter, crying or smiling, attributable to degeneration of bulbar upper motor neurons resulting in exaggeration of motor expressions of emotion.[citation needed] To be diagnosed with ALS, patients must have signs and symptoms of both upper and lower motor neuron damage that cannot be attributed to other causes. is an excerpt
