Objectives: To explore the anxiolytic effects of a 4-month randomized, placebo-controlled trial of exercise and antidepressant medication in patients with major depressive disorder (MDD), and to examine the potential modifying effects of anxiety in treating depressive symptoms.
Materials And Methods: In this secondary analysis of the SMILE-II trial, 148 sedentary adults with MDD were randomized to: (a) supervised exercise, (b) home-based exercise, (c) sertraline, or (d) placebo control. Symptoms of state anxiety measured by the Spielberger Anxiety Inventory were examined before and after 4 months of treatment.
Objective: Depression and cognitive impairment are often comorbid in older adults, but optimal treatment strategies remain unclear. In a two-site study, the efficacy and safety of add-on donepezil versus placebo were compared in depressed patients with cognitive impairment receiving stable antidepressant treatment.
Methods: A randomized, double-blind, placebo-controlled trial was conducted in older adults with depression and cognitive impairment (https://clinicaltrials.
Objective: To investigate whether there is a specific dose-dependent effect of the Apolipoprotein E (APOE) ε4 and ε2 alleles on hippocampal volume, across the cognitive spectrum, from normal aging to Alzheimer's Disease (AD).
Materials And Methods: We analyzed MR and genetic data on 662 patients from the Alzheimer's Disease Neuroimaging Initiative (ADNI) database-198 cognitively normal controls (CN), 321 mild-cognitive impairment (MCI) subjects, and 143 AD subjects-looking for dose-dependent effects of the ε4 and ε2 alleles on hippocampal volumes. Volumes were measured using a fully-automated algorithm applied to high resolution T1-weighted MR images.
