The authors had studied 55 cases with clinical seizure who were regularly treated with appropriate anticonvulsants over 6 months. In their distribution of age, teens are most freguent and their twenties followed. Males are more affected than female in the ratio of 3 to 2. Seizure may occur at any age; but our study shows that it is commoner in the first to third decades of life, about 72% of all cases, commonest in teens. The figures for 55 cases collected by us are : generalized type, 78% ; partial type, 22% ; 60% of all cases 33 are ldiopathic group, who had no demonstrable underlying neurologic abnormality. The major part of all idiopathic cases had their attacks of seizure before 30 years of age and; those of symptomatic cases are rather late over age of 30, and their figures are; cerebrovascular disorder, 6 cases; brain tumor, 5 cases; cerebral cysticercosis, 4 cases. 51 cases of all patients had evident abnormalities on their EEG. According to both their type of seizure and EEG findings, their drug was determined and, if need be, second drug was added. Freguently used drugs were dilantin, phenobarbital & Valproic acid etc. Mean therapeutic serum levels of anticonvulsants are: dilantin, 8.3 mg/L phenobarbital, 12.4 mg/L; which levels are less than those in U. S. A. In our study, the reponse to anticonvulsants were mostly good in about 2 years.
