Intractable epilepsy and disturbed visuomotor performance.
The factors relevant to intractability, types of epilepsy and impairment of dexterity in patients with intractable epilepsy were studied independently in different groups of patients. The factors relevant to intractable epilepsy that were disclosed in 202 patients, who required hospitalization more than twice, were as follows: strong seizure propensity, neuropsychiatric disorders including mental deterioration of various degrees, ataxia, personality changes and psychotic episodes, intolerance to antiepileptic drugs due to acute or chronic side effects, idiosyncrasy and internal disorders, self-induced seizure, misdiagnosis and mistreatment, and breakdown of family care of patients. The types of epilepsy in 224 patients with intractable epilepsy whose seizures were not adequately controlled and recurred on a monthly basis in spite of hospitalization were classified as follows: 101 patients with localization-related epilepsies or syndromes, 106 with generalized epilepsies or syndromes, 16 with undetermined epilepsies or syndromes and one with specific syndrome. In regard to partial epilepsies, frontal lobe epilepsy and partial epilepsy with multiple foci were at least partially intractable as temporal lobe epilepsy. With respect to intractable generalized epilepsies, miscellaneous symptomatic generalized epilepsies like intractable grand mal epilepsy with progressive mental retardation in childhood were as important as Lennox-Gastaut or West syndrome though it defies classification into any established syndromes. The proposed International Classification of Epileptic Syndromes and Epilepsies was found adequate for analysis of intractable epilepsy. The disturbance of fine motor performance found in 84 patients who participated in occupational therapy was investigated by test programs comprising nine subbatteries.(ABSTRACT TRUNCATED AT 250 WORDS)
