A survey on 465 patients with post-stroke depression in China.

The incidence of PSD patients is very high. To analyze the related factors and incidence of post-stroke depression (PSD). A total of 465 stroke patients were evaluated by a self-designed questionnaire, Self-Rating Depression Scale (SDS) and Hamilton Depression Rating Scale (HAMD). The neurologic deficit score was tested using the National Institute of Health stroke scale (NIHSS). A multiple factor analysis with the logistic regression method was carried out to analyze related factors of PSD. A total of 146 cases (31.4%) were identified as suffering from PSD. In addition the stepwise regression analysis showed that important risk factors of PSD included of sex, lesion location, the course of post-stroke and degree of neurological deficit score (all P<0.05). Above mentioned factors about the patients of PSD are very significant and may provide reference for further treating.
