automatisms
Pronunciation: aw-TOM-ah-tizms
Repetitive, stereotyped movements or behaviors that occur during seizures, performed without conscious awareness.
Full Definition
Automatisms are repetitive, stereotyped motor behaviors that occur during seizures, particularly complex partial seizures, while the patient's consciousness is impaired. These involuntary actions appear purposeful but are performed without awareness or voluntary control. Common automatisms include lip smacking, chewing, swallowing, fumbling with clothes, walking aimlessly, or repetitive hand movements. Automatisms are classified as oroalimentary (mouth/eating related), manual (hand movements), gestural (complex movements), verbal (speech), or ambulatory (walking). They provide important localizing information about seizure origin.
Usage
Usage note: Always use plural form; specify type (oroalimentary, manual, etc.) when describing.
