Adolecsent mania, EEG abnormality and response to anticonvulsants: a three - year follow-up study.

We had reported earlier (1998) a high percentage of moderate to severe EEG abnormalities (43.75% of cases) amongst adolescent manic population. Sixteen adolescent manics, with a mean age of 14 9 years, diagnosed according to ICD-10 were taken up for the initial study. Present study is the three-year follow-up report of 67.75% (11 out of 16) of the original patient population. All these patients were subjected fc 21-channel EEG and anticonvulsant drugs were started to all. Follow-up data showed that 3 out of 6 patients, who discontinued medications, were relapsed during this 3 years period. But none of the 5 patients, who regularly took prescribed medicines, relapsed during the same period. Significance of these findings in relapse prevention and the role of anticonvulsants, particularly in relation to adolescent mania, have been emphasized.
