A reappraisal of poststroke depression, intra- and inter-hemispheric lesion location using meta-analysis

J Neuropsychiatry Clin Neurosci. 2003 Fall;15(4):422-30. doi: 10.1176/jnp.15.4.422.


A recent publication based on a meta-analysis concluded that there was no association between poststroke depression (PSD) and lesion location. This study, therefore, was undertaken to reappraise the hypothesis using meta-analysis of the correlation between severity of depression following stroke and proximity of the lesion to the frontal pole, an issue that was not examined in the prior meta-analysis. Results showed there was a significant inverse correlation between severity of depression and distance of the lesion from the frontal pole among 163 patients with left hemisphere stroke but not among 106 patients with right hemisphere stroke. This study supports the hypothesis that risk of poststroke depression is related to the location of brain injury.
