Abstract

Diagnosis of mental illness in mentally-handicapped people is often difficult and complex, because of atypical presentation and lack of clear diagnostic criteria. A patient in whom seasonal variation in behaviour and mood gave a clue to the diagnosis of manic-depressive psychosis is reported.
