Treatment of 'brain fag' syndrome.

Sixty male Nigerian students suffering from 'brain fag' syndrome who had failed to respond satisfactorily to 4 to 8 weeks' treatment with other benzodiazepines were treated with 1 to 2 mg. lorazepam t.i.d. There was marked improvement in symptoms in over 80% of the patients by the end of the second week of lorazepam treatment. Side-effects were considerably less frequent or incapacitating than with the previous therapy.
