Validation of the Performance of the French Version of the Cerebellar Cognitive-Affective Syndrome Scale (CCASS) as a Screening Test for Cerebellar Cognitive-affective Syndrome: a National Multicenter Study

The CCASS will be administered by a neuropsychologist starting with version 1A. An alternative version (1B, 1C or 1D) will also be administered. An interval of approximately 30 minutes should be observed between the two administrations. In order to assess the inter-rater reliability of the scale, a second neuropsychologist will be present in the room and will independently evaluate (i.e., blind to his/her colleague's rating) patient's responses. The choice of alternative version (i.e., 1B, 1C, or 1D) will be randomized.
