convulsio

Convulsio is a term used to describe convulsions or seizures, derived from Latin convulsio meaning "a seizure" or "convulsing". In medical English, convulsion is the common term, but convulsio appears in historical texts and some non-English vocabularies and is sometimes used interchangeably with seizure.

Generalized convulsio involves widespread muscle stiffness and rhythmic jerking, often with loss of consciousness. Focal convulsio originate in a specific brain region and may cause one-sided movements, sensory changes, or speech disturbances. Some events are brief or subtle, and postictal confusion can follow.

Causes include epilepsy, febrile seizures in children, metabolic disturbances (glucose, sodium, or calcium imbalances), intoxication, withdrawal from alcohol or drugs, head injury, stroke, infections, tumors, and autoimmune conditions. Triggers such as sleep deprivation, stress, or flashing lights can provoke seizures in predisposed individuals.

Diagnosis relies on history and observation, supported by electroencephalography (EEG) and targeted laboratory tests. Neuroimaging is used when a structural disease is suspected. Classification follows seizure type and level of awareness to guide management.

Management focuses on safety during events, treating reversible causes, and, if indicated, long-term control with antiepileptic drugs. Acute treatment aims to stop ongoing convulsions, and prolonged seizures require emergency care.
