Manic and depressive symptoms in the elderly: their relationships to treatment outcome, cognition and motor symptoms.

70 subjects aged over 65 were evaluated within 48 h of admission in order to ascertain the correlation between manic and depressive symptoms and cognitive disorder, multi-infarct changes, abnormal movements, and extrapyramidal signs. Manic symptoms were found to be more often correlated with multi-infarct changes, lower cognitive scores, disordered behaviour, and bad outcome. The meaning of these findings is discussed.
