Abstract
Background and Purpose—Patients with poststroke major depression have a greater severity of cognitive impairment than nondepressed patients even when matched for size and location of stroke lesion. Prior treatment studies have consistently failed to show an improvement in cognitive function even when poststroke mood disorders responded to antidepressant therapy. We examined the response of cognitive function to treatment with nortriptyline or placebo in a double-blind trial. Methods—Patients with major (n=33) or minor (n=14) depression participated in a double-blind treatment study with nortriptyline or placebo. They were examined for change in depressive mood, measured by the Hamilton Rating Scale for Depression (HAM-D), and change in cognitive impairment, assessed by the Mini-Mental State Examination (MMSE), after treatment with nortriptyline or placebo. Cognitive treatment response, as measured by the MMSE, was compared between patients whose depression did and did not respond to treatment. Results—Pat...
