Abstract:
Objective To investigate the correlation between post-stroke depression(PSD) and cerebral microbleeds(CMBs)in elderly patients with ischemic stroke.Methods In the prospective study,220 elderly patients with ischemic stroke were enrolled and followed up to one month after onset.Finally a total of 214 elderly patients performed a follow-up.According to DSM-Ⅳ Diagnostic and Statistical Manual of Mental Disorders,patients were divided into the PSD group and non-PSD group.The degree of depression was evaluated by17-item Hamilton Depression Scale(HAMD-17)score,and patients were divided into mild depression,moderate depression and severe depression group.The loci number,distribution and location of CMBs lesions were assessed by SWI.Patients were divided into brain lobe type,deep lobe type and mixed type according to the CMBs lesion location.The influence of CMBs or not,loci number and location of CMBs lesions on PSD were compared.Results A total of 214 elderly patients with ischemic stroke were enrolled,in whom 84(84/214,39.3％)had PSD with 29(34.5％)males and 55(65.5％)females.According to the HAMD scale,there were 51 patients (60.7 ％) with mild depression,25 (29.8 ％) with moderate depression,and 8 (9.5 ％) with severe depression.The prevalence rate of CMBs was 62.5 ％ (32/51) in mild depression group,71.0 ％ (22/25) in moderate depression group,81.8 ％ (6/8)in severe depression group and 45.4 ％ (49/108)in non PSD group(all P=0.008).The number of CMBs lesions were(4.5±1.2)in mild depression group,(7.8± 2.0)in moderate depression group,(12.6±2.7)in severe depression group and(1.8±0.5)in non-PSD group,with the statistically significant differences between groups (F =2.79,P =0.041).The proportions of CMBs lesions location(brain lobe type,deep lobe type and mixed type)were 40.6 ％ (13/32),34.4％(11/32) and 25.0％ (8/32) in mild depression group,36.4％(8/22),40.9％(9/22) and 22.7％(5/22) in moderate depression group,33.3％ (2/6),50.0％ (3/6) and 16.7％ (1/6) in severe depression group,40.8％ (20/49),12.2％ (6/49) and 46.9％ (23/49) in non-PSD group,respectively (Fisher exact test,P =0.043).The proportions of CMBs lesions distribution(left side,right side and double side)were 37.5％(12/32),43.8％(14/32) and 18.8％(6/32) in mild depression group,36.4％ (8/22),40.9％ (9/22) and 22.7％ (5/22) in moderate depression group,50.0％ (3/6),33.3％ (2/6)and 16.7％(1/6) in severe depression group,36.7％(18/49),40.8％(20/49) and 22.5％(11/49) in non-PSD group,and the difference was not statistically significant (Fisher exact test,P =0.998).Conclusions The prevalence rate of CMBs,number of CMBs lesions and deep lobe type of CMBs are closely related to the degree of post-stroke depression in the elderly.The distribution of CMBs lesions has no relevance with the degree of post stroke depression in the elderly.Elderly patients with ischemic stroke at high risk of post-stroke depression can be identified by evaluating CMBs for early intervention,which is worthy of promotion in clinical work.
