This study will assess the performances of the Montreal Cognitive Assessment (MoCA) to screen for cognitive impairment in adults with sickle cell anemia. The results of the MoCA and its subscores will be compared to a standardized neuropsychological evaluation using validated tests.
Sickle cell anemia is a monogenic disease affecting the beta-chain of hemoglobin. Cognitive impairment is more prevalent in patients with sickle cell disease than in matched unaffected individuals. Validated tests to screen for cognitive impairment are lacking in this population. Our goal is therefore to assess the performance of the Montreal Cognitive Assessment (MoCA) as a screening tool for cognitive impairment in adults with sickle cell anemia. The results of the MoCA and its subscales will be compared to a standardized neuropsychological evaluation using validated tests.
