Objective: The aim of this study was to investigate relationships between cognitive impairment and functional outcomes in stroke patients with spatial neglect.
Method: Twenty seven right hemisphere ischemic stroke patients who admitted to an inpatient rehabilitation unit were included. Patients were divided into two group based on KF-NAP scores: Neglect group (n=18) and non-neglect group (n=9). Neglect group (n=18) were subdivided into two groups by discharge FIM scores as poor outcome group (n=8, ＜70) and good outcome group (n=10, ≥70). Cognitive function assessments including attention (Attention & Calculation, Digit span test?Forward), memory (Digit span test?Backward, SVLT-Immediate recalls/Delayed recalls) and visual perception (LOTCA-Visual perception/Visuomotor organization), and stroke severity assessment including NIHSS, FMA, K-MMSE, and FIM were performed. Cognitive impairments and functional outcomes were compared between two groups.
Results: There were significant differences in NIHSS, FMA (affected U/E, affected L/E), discharge FIM, FIM gain and LOTCA-visuomotor organization between Neglect group and non- neglect group (p＜0.05). Among the patients with spatial neglect, there were significant differences in KF-NAP, K-MMSE and assessment scores of memory and visual perception between poor outcome group and good outcome group. Attention, memory and visual perception were sig-nificantly correlated with KF-NAP scores (p＜0.05).
Conclusion: Stroke patients with spatial neglect showed more severe impairment in cognitive, motor and general func-tional status, which resulted in delayed functional recovery. Spatial neglect patients with combined memory and visual perception impairment may show poor functional outcome.
