A longitudinal examination of the frequency and correlates of self-reported neurobehavioural disability following stroke

Purpose To determine the frequency, impact, and factors associated with self-reported neurobehavioural disability (NBD) in individuals with stroke. A secondary aim was to examine the course of self-reported NBD over time and associations with outcomes. Methods Eighty-seven participants admitted for inpatient rehabilitation post-stroke completed the St Andrew's-Swansea Neurobehavioural Outcome Scale. Demographic and stroke details and measures of functional disability, cognitive impairment, mood, and self-rated impact of NBD symptoms were completed. Twenty-seven participants and 19 close-others were reassessed three to six months following discharge. Results Overall reporting of neurobehavioural problems was infrequent. The domains of interpersonal and cognitive difficulties were the most commonly identified but were still only reported occasionally. However, even mild NBD was significantly correlated with negative impact. Greater self-reported NBD was significantly correlated with greater functional dependence, anxiety, and depression during inpatient rehabilitation. Self-reports of NBD remained stable over time and, at follow-up, was significantly correlated with depressive symptoms both in participants with stroke and close-others. Conclusions In survivors of stroke, self-report of NBD is associated with poor outcomes in function, anxiety, and depression. These findings highlight the importance of routine and comprehensive assessment and intervention to manage NBD following stroke.
