Abstract

Purpose: To evaluate the cerebellar cognitive affective syndrome scale (CCAS-S) in patients with acute cerebellar stroke (ACS) and examine its relationship with the discharge destination.

Methods: Patients with first-time ACS admitted to our hospital between April 2021 and April 2023 were included. The CCAS-S, Mini-Mental State Examination (MMSE), and Scale for the Assessment and Rating of Ataxia (SARA) were evaluated 1 week after stroke onset, and Functional Independence Measure (FIM)/Barthel Index (BI) at discharge, duration of hospitalization, and discharge destination were evaluated. The Mann-Whitney U test was used to compare CCAS-S and variables.

Results: Thirteen consecutive patients with ACS and age-matched comparison groups were included. The MMSE was within the normal range in all patients; however, patients with stroke had a lower total CCAS-S score (median 72, IQR 66-80) and a higher number of failed tests (median 4, IQR 3-5) than comparison. Significant deficits were observed in semantic fluency (p = 0.008), category switching (p = 0001), and similarity (p = 009). Definite CCAS were diagnosed 10 patients, respectively. Patients discharged home showed better SARA and FIM/BI but similar CCAS-S compared to those discharged to rehabilitation hospitals.

Conclusion: In patients with ACS, it is the impairment of motor function, not CCAS, that affects discharge destination.
