Given the doses of medication used in this study, nortriptyline was superior to fluoxetine in the treatment of poststroke depression. Demonstrating a benefit of antidepressant treatment in recovery from stroke may require the identification of specific subgroups of patients, alternative measurement scales, or the optimal time of treatment.
While dysthymia in AD is a brief emotional disorder, major depression is a longer-lasting mood change. Anosognosia is another prevalent disorder among AD patients, and increases with the progression of the illness.
Patients with IVD showed a relatively more severe dysfunction of the frontal lobes as demonstrated by single-photon emission CT and expressed in specific psychiatric and neuropsychological changes than AD patients matched for age, sex, and severity of dementia.
Objective: To examine the efficacy of fluoxetine in the treatment of depression in patients with probable Alzheimer's disease (AD). Methods: This double-blind, parallel-design study included a consecutive series of 41 AD subjects meeting DSM-IV criteria for major or minor depression who were randomized to receive fluoxetine (up to 40 mg/day) or identical-appearing placebo. All patients received biweekly evaluations consisting of the Hamilton Depression Scale (HAM-D) and the Clinical Global Impression as primary efficacy measures, and the Mini-Mental State Exam, Hamilton Rating Scale for Anxiety, and the Functional Independence Measure as secondary efficacy measures. Results: Complete remission of depression was found in 47% of subjects treated with fluoxetine and in 33% of subjects treated with placebo. Both the fluoxetine and the placebo groups showed a significant decline in HAM-D scores over time, but the magnitude of mood improvement was similar for both groups. Fluoxetine was well tolerated, and most side effects were mild. Conclusion: Fluoxetine treatment for depression in AD did not differ significantly from treatment with placebo. Our study also confirms the presence of a placebo effect in the treatment of depression in AD.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
