NCT05347043

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • sensitivity of a Montreal Cognitive Assessment score < 26 to detect cognitive impairment confirmed by a neuropsychological standardized evaluation

    sensitivity of a Montreal Cognitive Assessment score \< 26 to detect cognitive impairment defined as an abnormal result in at least one of the following tests : Test of Attentional Performance of Zimmermann and and Fimm (\< 5th percentile in at least one of the subscales) ; Wechsler Adult Intelligence Scale 4th version digit span (standard score ≤ 5) ; Wechsler memory scale III, spatial span (standard score ≤ 5) ; Wisconsin Card Scoring Test, GREFEX version (number of categories ≤ 5th percentile or if the number of perseverations is ≥ 95th percentile) Wechsler Adult Intelligence Scale 4th version block design (standard score ≤ 5) ; Six elements test GREFEX version (rank score ≤ 5th percentile ); free and cued selective reminding test, 16 items, B version (Z-score ≤ -1,65 in at least one of the subscales)

    Month 3

Secondary Outcomes (5)

  • specificity of a Montreal Cognitive Assessment score < 26 to detect cognitive impairment confirmed by a neuropsychological standardized evaluation

    Month 3

  • sensitivity of a Montreal Cognitive Assessment score < 23 to detect cognitive impairment confirmed by a neuropsychological standardized evaluation

    Month 3

  • sensitivity and specificity of a score ≤ 5/6 in the attention subscale of the Montreal Cognitive Assessment to detect attentional impairment confirmed by a neuropsychological standardized evaluation

    Month 3

  • sensitivity and specificity of a score ≤ 4/5 in the visuospatial/executive subscale of the Montreal Cognitive Assessment to detect executive impairment confirmed by a neuropsychological standardized evaluation

    Month 3

  • sensitivity and specificity of a score ≤ 4/5 in the delayed recall subscale of the Montreal Cognitive Assessment to detect a long term memory impairment confirmed by a neuropsychological standardized evaluation

    Month 3

Study Arms (1)

Intervention

EXPERIMENTAL

All patients will undergo both the MoCA test and the standardized neuropsychological evaluation Montreal cognitive assessment and standardized neuropsychological evaluation (Test of Attentional Performance of Zimmermann and Fimm ; Wechsler Adult Intelligence Scale 4th version digit span ; Wechsler memory scale III, spatial span ; Wisconsin Card Scoring Test, GREFEX version ; Wechsler Adult Intelligence Scale 4th version block design ; Six elements test GREFEX version; free and cued selective reminding test, 16 items, B version ; Behavioral Rating Inventory of Executive Function ; Modified Fatigue Impact Scale)

Other: Montreal cognitive assessment

Interventions
