Grand mal discharge.
Two hundred nineteen grand mal discharges were reviewed in 50 epileptic patients. It was commonly seen in patients with prenatal and perinatal causes, mental deficiency with neurological deficits, and multiple types of seizures. Eighty-eight percent of the discharges were bilaterally synchronous with 49 percent of bifrontal predominance. Fifty-eight percent were associated with drowsiness or sleep, and 64 percent were associated with clinical accompaniments. The most common clinical signs were tonic movement of arms, legs or neck, eye opening, eye fluttering, head drop, etc. The increased frequency of clinical seizures usually observed during the occurrence of this pattern may provide some clues that the antiepileptic medication should be reassessed to control the oncoming seizure attacks.
