Mianserin, maprotiline and the electroencephalogram.

Abstract
1 EEGs were recorded from patients with depressive illness before and after four weeks of treatment with mianserin, maprotiline or placebo. 2 Visual analysis of the records showed a small but statistically significant increase in frequency of beta activity in the mianserin group. 3 One subject taking maprotiline developed spike and wave discharges but had no convulsive seizures. 4 The findings do not support those of previous studies. It seems that changes seen in the EEG early after treatment are not sustained for four weeks.
