The Impact of Acute Phase Domain-Specific Cognitive Function on Post-stroke Functional Recovery

Area of Science:

• Neurology
• Neuropsychology
• Rehabilitation Medicine

Background:

• Stroke recovery is influenced by various factors, including cognitive function.
• Early assessment of cognitive deficits is crucial for predicting long-term outcomes.

Purpose of the Study:

• To determine if acute-stage cognitive function, assessed via domain-specific tests, independently predicts functional outcomes post-stroke.
• To evaluate the prognostic value of neuropsychological assessments in stroke patients.

Main Methods:

• Forty stroke patients underwent four neuropsychological tests (BNT, CRT, CPT, VFT) approximately 3 weeks post-stroke.
• Functional outcomes were measured using the Korean version of the Modified Barthel Index (K-MBI) at 3 months and the modified Rankin Scale (mRS) at 6 months.
• Regression analysis identified predictors of functional improvement and status.

Main Results:

• Impaired performance on the construction praxis test (CPT) and construction recall test (CRT) predicted better functional improvement (change in K-MBI) within 3 months.
• CPT and CRT scores also independently predicted functional status at 6 months, as assessed by mRS.

Conclusions:

• Visuospatial construction and memory deficits in the acute phase of stroke are significant prognostic indicators for functional outcomes.
• Domain-specific neuropsychological assessments in the acute stage can aid in predicting long-term functional recovery in stroke patients.
