No Melancholia in Poststroke Depression? A Phenomenologic Comparison of Primary and Poststroke Depression

Differences between both groups of patients indicate that careful considerations and further research are needed before treatment strategies developed for and evaluated in patients with primary depression are applied to patients with PSD.

Abstract

The present study aimed at the phenomenologic comparison of depressive symptoms in elderly patients with poststroke depression (PSD) or primary depression (depression without a known neuropathology). We investigated 20 patients with PSD and 41 patients with primary depression. A structured clinical interview based on the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, self- and observer-based depression rating scales, a clinical neurologic examination, and neuroradiologic analysis based on standardized computed tomographic scan analysis were applied. The Cornell Depression Scale was used to compare mood-related signs, behavioral disturbances, physical signs, disturbances of cyclic signs, and ideational disturbances in both groups of patients. Those with PSD exhibited no melancholia and fewer cyclic and ideational disturbances but more physical signs of depression. These findings are in line with those of endocrinologic studies. Differences between both groups of patients indicate that careful considerations and further research are needed before treatment strategies developed for and evaluated in patients with primary depression are applied to patients with PSD.
