Abstract
Depressed geriatric patients [3] had a marked therapeutic response to the psychostimulant drug methylphenidate. These patients either were unable to tolerate tricyclic antidepressants or had a medical illness that contraindicated tricyclic therapy. The lack of adverse effects in our elderly patients and methylphenidate''s effectiveness as an antidepressant were consistent with the findings of other investigators. Apparently psychostimulants deserve further evaluation as antidepressant agents in the geriatric population.
