Cerebellar Cognitive Affective Syndrome

The primary objective of the study is to assess the performance of the French version of the Cerebellar Cognitive-Affective Syndrome Scale (CCASS) as a screening test for cerebellar cognitive-affective syndrome. The primary endpoint will be the sensitivity of version 1A of the French scale. The result will be considered positive if the patient fails at least one of the scale's subtests. The diagnosis of a cerebellar cognitive-affective syndrome will be made on the basis of a pathological score in the executive, language, visuospatial or psychoaffective domains of the neuropsychological evaluation (gold standard).
