Why the study?
Is the presence of silent cerebral infarction associated with different levels of psychosocial stressors in patients with major depression?
Is the presence of silent cerebral infarction associated with different levels of psychosocial stressors in patients with major depression?
In patients with major depression, the presence of silent cerebral infarction is associated with lower psychosocial stressor scores, suggesting a stronger neurological rather than psychosocial etiology in these patients.
Lower axis IV scores with SCI in major depression suggest neurological factors may predominate; hypothesis-generating for etiology and requires prospective studies.
BACKGROUND AND PURPOSE: 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.
