Reflex asystolic syncope

Reflex asystolic syncope, reflex anoxic seizures or RAS are a form of syncope encountered mainly, but not exclusively, in young children. Reflex anoxic seizures are not epileptic seizures or epilepsy. This is usually a consequence of a reduction in cerebral perfusion by oxygenated blood. It can be a result of either a sudden reduction in the blood flow to the brain, a drop in the oxygen content of the blood supplying the brain, or a combination of the two. Syncope can have different meanings ranging from transient loss of consciousness, usually accompanied by a decrease or loss in postural tone (the principal manifestations of “simple faints”), to tonic and myoclonic events and nonepileptic spasms.

Syncope (phonology)

In phonology, syncope (/ˈsɪŋkəpiː/; Greek: syn- + koptein "to strike, cut off") is the loss of one or more sounds from the interior of a word, especially the loss of an unstressed vowel. It is found both in synchronic analysis of languages and diachronics. Its opposite, whereby sounds are added, is epenthesis. A syncope rule has been identified in Tonkawa, an extinct American Indian language, whereby the second vowel of a word deletes if it is not adjacent to a consonant cluster or final consonant.

Synchronic analysis

Synchronic analysis studies linguistic phenomena at one moment, usually the present. In modern languages, syncope occurs in inflection, poetry, and informal speech.

In inflections

In languages such as Irish, the process of inflection can cause syncope.

For example :

It is interesting that if the present root form in Irish is the result of diachronic syncope, there is a resistance to synchronic syncope for inflection.
