Psychomotor-variant type of paroxysmal cerebral dysrhythmia

Psychomotor-variant is a rare clinico-electroencephalographic entity, characterized by a great variety of thalamic, hypothalamic and limbic symptoms and by a specific electrographic finding during light sleep, i.e. discharges of notch-topped 6 per second waves, chiefly in the temporal areas. It is rare, occurring among only one percent of patients with epilepsy or a question of epilepsy. Sixty-eight percent of patients with psychomotor-variant disorder improved symptomatically if treated with anti-epileptic medication.
