✦ Synopsis

Abstract

Background

Late life depression is associated with volumetric reductions of gray matter and increased prevalence of subcortical white matter lesions. Previous studies have shown a poorer treatment outcome in those with more severe structural brain abnormalities. In this study, quantitative and semi‐quantitative magnetic resonance imaging (MRI) measures were studied in relation to response to a 12‐week controlled antidepressant monotherapy trial.

Methods

MRI (1.5T) brain scans of 42 elderly inpatients with major depression, of which 23 were non‐responder to a controlled 12‐week antidepressant monotherapy trial, were acquired. In addition, clinical outcome was assessed after a one year period. Measures were volumes of global cerebral and subcortical structures.

Results

After controlling for confounding, no differences were found between non‐responders and responders after 12 weeks and after one year in volumes of cerebral gray and white matter, orbitofrontal cortex, hippocampus and white matter lesions.
