Apathy and depression during the recovery stage after stroke

Abstract

Background/Aims Both apathy and depression occur during the recovery period following stroke; however, the relationship between post-stroke apathy and depression is still unclear. The present study investigated the clinical course of apathy and its association with depression, cognitive function and daily function during the recovery period after stroke. Methods A total of 42 patients (29 male and 13 female, aged 69.1 ± 12.4 years) who had experienced stroke participated in this study. Each participant was assessed using the Apathy Scale, Self-rating Depression Scale, Mini-Mental State Examination, Clinical Assessment of Attention and Trail-Making-Test parts A and B. Quality of life was evaluated using the Stroke Specific Quality of Life Scale. Physical function and functional status were assessed using the Brunnstrom Stages of Stroke Recovery and Functional Independence Measure respectively. Results The incidence of apathy did not change from the time of admission to discharge. Apathy Scale score did not correlate with Self-rating Depression Scale score at admission, but it did correlate at the time of discharge. Patients with apathy after stroke suffered from greater cognitive disturbance and attention and executive dysfunctions than those without apathy. Total Functional Independence Measure score did not correlate with Apathy Scale or Self-rating Depression Scale score, but there was an association between Self-rating Depression Scale score and the Functional Independence Measure motor and Brunnstrom scores at discharge. Conclusions Apathy and depression had different relationships with cognitive and physical function during the recovery stage after stroke. The prevalence of apathy and depression changed, with the interrelationship between apathy and depression altering during the recovery period. Symptoms of apathy and depression should be distinguished from each other and appropriately evaluated to provide effective intervention to support physical and mental recovery after stroke.
