Abstract

Objective: The purpose of the present study is to evaluate the association between poststroke depression (PSD) and clinical outcomes in first-onset stroke patients who are undergoing a rehabilitation program.

Methods: The present study included 180 inpatients that were recruited consecutively and followed up over a 6-month observational period. Poststroke depression was diagnosed using the criteria of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. Symptoms of depression and clinical outcomes were assessed using the Beck Depression Inventory, the modified Barthel Index (MBI) and the Mini Mental State Examination (MMSE). All patients were assessed at baseline and at the end of the 6-month observational period.

Results: Of the 180 patients, 127 (70.6%) were diagnosed with minimal-to-mild depression (MMD), and 53 (29.4%) were diagnosed with moderate-to-severe depression (MSD). The mean change in MBI scores from baseline to 6 months was significantly higher (P=.029) in the MMD group (23.8) than in the MSD group (8.6). The odds ratio for an unfavorable outcome (MBI score <60) in patients with MSD was approximately 3.5 in relation to patients with MMD. The mean change in MMSE score (4.4 versus 7.4) was not significantly different between the MMD and MSD groups.

Conclusion: The present findings suggest that the severity of PSD may be associated with clinical outcomes in Korean patients 6 months after a first-onset stroke. Our data agree with previous findings, which indicate that clinicians should carefully evaluate symptoms of depression in stroke patients during routine clinical practice. The methodological shortcomings of the present study may require further studies with adequate power and improved design to clarify the association between PSD and clinical outcomes following stroke.
