Are there two depressive syndromes after stroke?

The objective of this study was to describe the clinical characteristics of minor depression after stroke and to compare this disorder with poststroke major depression and the nondepressed state. Ninety-four stroke inpatients were examined 8 weeks after stroke and reexamined 15 months later. Twenty-one (22%) of the 94 patients suffered from minor depression, 14 (15%) suffered from major depression, and 59 (63%) were not depressed. Minor depressed patients were twice as symptomatic as nondepressed patients but were only half as symptomatic as major depressed patients. Minor depressed patients were more likely than nondepressed patients to have a previous history of stroke and were more physically disabled. They were less likely than major depressed patients to have a family history of affective disorder. Depression symptom severity was associated with greater physical disability among minor but not major depressed patients. Fewer minor than major depressed patients were depressed at 15 months. These findings suggest that poststroke major and minor depression may be different depressive syndromes. Some cases of minor depression may be construed as an adjustment reaction to stroke disability
