title: Psychosocial stressors in patients with major depression and silent cerebral infarction.
abstract: OBJECTIVE
  We previously found that silent cerebral infarction (SCI) was present in most of the patients older than 50 years with major depression who were examined. The present study was designed to clarify the relationship between psychosocial stressors and SCI in patients with major depression.
  
  
  METHODS
  Forty-two patients with unipolar depression underwent MRI and were classified as SCI-negative (n = 19) or SCI-positive (n = 23). The SCI-positive group was subclassified into those with moderate SCI (n = 16) and those with severe SCI (n = 7). The relationship between the patients' DSM-III-R axis IV scores and SCI was evaluated.
  
  
  RESULTS
  The axis IV score was significantly lower in the SCI-positive group than in the SCI-negative group (P < .05). Within the SCI-positive group, the mean axis IV score was significantly lower in those with severe SCI than in those with moderate SCI (P < .05).
  
  
  CONCLUSIONS
  Our findings suggest that depression in patients with SCI involves more neurological factors than psychosocial stressors.
