epilepsy /ep·i·lep·sy/ (ep´ĭ-lep″se) any of a group of syndromes characterized by paroxysmal transient disturbances of brain function that may be manifested as episodic impairment or loss of consciousness, abnormal motor phenomena, psychic or sensory disturbances, or perturbation of the autonomic nervous system; symptoms are due to disturbance of the electrical activity of the brain.
jacksonian epilepsy
absence epilepsy that characterized by absence seizures, usually having its onset in childhood or adolescence.
focal epilepsy that consisting of focal seizures.
generalized epilepsy epilepsy in which the seizures are generalized; they may have a focal onset or be generalized from the beginning.
grand mal epilepsy a symptomatic form of epilepsy, often preceded by an aura, characterized by sudden loss of consciousness with tonic-clonic seizures.
jacksonian epilepsy epilepsy marked by focal motor seizures with unilateral clonic movements that start in one muscle group and spread systematically to adjacent groups, reflecting the march of epileptic activity through the motor cortex.
juvenile myoclonic epilepsy a syndrome of sudden myoclonic jerks, occurring particularly in the morning or under periods of stress or fatigue, primarily in children and adolescents.
Lafora's myoclonic epilepsy a form characterized by attacks of intermittent or continuous clonus of muscle groups, resulting in difficulties in voluntary movement, mental deterioration, and Lafora bodies in various cells.
myoclonic epilepsy any form of epilepsy accompanied by myoclonus.
petit mal epilepsy absence e.
photic epilepsy , photogenic epilepsy reflex epilepsy in which seizures are induced by a flickering light.
posttraumatic epilepsy that occurring after head injury.
psychomotor epilepsy temporal lobe e.
reflex epilepsy epileptic seizures occurring in response to sensory stimuli.
rotatory epilepsy temporal lobe epilepsy in which the automatisms consist of rotating body movements.
sensory epilepsy
1. seizures manifested by paresthesias or hallucinations of sight, smell, or taste.
2. reflex e.
somatosensory epilepsy sensory epilepsy with paresthesias such as burning, tingling, or numbness.
temporal lobe epilepsy a form characterized by complex partial seizures.
visual epilepsy sensory epilepsy in which there are visual hallucinations.
jack·so·ni·an epilepsy (j k-s  n - n)n. A form of focal epilepsy in which a seizure progresses from the distal to the proximal muscles of a limb. |
jacksonian epilepsy
[jaksō′nē·ən]
epilepsy characterized by focal motor seizures with unilateral clonic movements that start in one group of muscles and spread systematically to adjacent groups, reflecting the march of the epileptic activity through the motor cortex (jacksonian march). The seizures are due to a discharging focus in the contralateral motor cortex.
Jacksonian epilepsy
a form of epilepsy marked by clonic movements that start in one muscle group and spread systematically to adjacent groups.
