Epilepsy as a manifestation of neurocysticercosis.

Epilepsy is the commonest manifestation of neurocysticercosis. Epilepsy was observed in 127 of 150 cases (84.7%) of neurocysticercosis seen over a period of 17 years. The basis of diagnosis was clinical presentation and concomitant evidence of extraneural cysticercosis in the pre-computed tomography (CT) scan era, and typical CT findings in later years. Eighty one cases (54%) who primarily presented as epilepsy without any neurological deficit have been analysed in detail. In the pre-CT period the occurrence of epilepsy as a presenting feature in neurocysticercosis was 43.5% whereas in later years it was 61.4%. Primary generalised seizure (49 cases) was more common than partial seizure (29) and partial complex seizure (3). Status epilepticus was seen in 6 cases. Magnetic resonance imaging, done in 8 cases, proved to be more sensitive in demonstrating various stages in the development of noncalcified cysticercosis. The new larvicidal drugs offer a potential cure and cysticercosis should be entertained as a cause of epilepsy especially in endemic areas.
