psychomotor seizure

a temporary impairment of consciousness characterized by psychic symptoms, loss of judgment, automatic behavior, and abnormal acts. It is often associated with temporal lobe disease. No apparent convulsions occur, but there may be loss of consciousness or amnesia for the episode. During the seizure the individual may appear drowsy, intoxicated, or violent and may commit asocial acts or crimes, but normal activities, such as driving a car, typing, or eating, may continue at an automatic level. Psychic symptoms, including visual and auditory hallucinations, a sense of unreality, and déjà vu, may be present and may be accompanied by visceral symptoms, such as chest pain, transient respiratory arrest, tachycardia, and GI discomfort, and by abnormal sensations of smell and taste. Also called psychomotor epilepsy.

temporal lobe seizure

A simple or complex seizure caused by abnormal electrical activity in the temporal lobes, which may result in transient changes in movement, sensation, autonomic function, alertness and awareness.
 
Clinical findings
Temporary paralysis, sleep paralysis, fear sensation, hallucinations (e.g., delusion of lycanthropy, or misinterpreted as UFO abductions). Temporal lobe seizures may occur in anyone at any age, as a single episode, or as a chronic seizure disorder.
 
Diagnosis
Abnormal electrical activity on EEG.
 
Aetiology
Temporal lobe damage (trauma, hypoxia), ischaemia and/or infarction, tumours, infection or any other discrete lesion.

Management
Phenytoin, phenobarbital, carbamazepine, valproate.

psychomotor seizure

Complex partial seizure, psychomotor epilepsy, temporal lobe epilepsy Neurology A seizure disorder involving abnormal discharge of neurons of the temporal lobe with episodic changes in behavior accompanied by loss of consciousness, with retention of capacity to respond to environmental stimuli. See Paraphilia.

Jacksonian seizure
partial seizure
one restricted to a focus in the brain; signs correspond to the area affected, e.g. motor activity of an isolated area or limb, hallucinations such as fly catching, apparent blindness, behavioral abnormalities, etc. Called also focal seizures.
petit mal seizure
a mild, very brief generalized seizure. See also petit mal.
photogenic seizure
a seizure brought on by light.
psychomotor seizure
motor seizures accompanied by a psychic stage. There are hallucinations, salivation, pupillary dilatation, mastication, fecal and urinary excretion, and wild running. Seen in dogs with lesions in the pyriform lobe or hippocampus and from poisoning with agenized flour (canine hysteria). Called also running fits.
tetanic seizure
see tetany.
seizure threshold
the level of stimulation at which a seizure is precipitated.
tonic seizure
one in which the muscles are rigid.
tonic-clonic seizure
alternating tonic (rigid muscles) and clonic (jerking of muscles) phases; a grand mal seizure.
