Study Details

Study Description

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.

Condition or Disease Intervention/Treatment Phase
  • Other: Montreal cognitive assessment
N/A

Detailed Description

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.

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
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)

Outcome Measures

Primary Outcome Measures

  1. sensitivity 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 < 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)

Secondary Outcome Measures

  1. specificity of a Montreal Cognitive Assessment score < 26 to detect cognitive impairment confirmed by a neuropsychological standardized evaluation [Month 3]

    specificity 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 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)

  2. sensitivity of a Montreal Cognitive Assessment score < 23 to detect cognitive impairment confirmed by a neuropsychological standardized evaluation [Month 3]

    sensitivity of a Montreal Cognitive Assessment score < 23 to detect cognitive impairment defined as an abnormal result in at least one of the following tests : Test of Attentional Performance of Zimmermann 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)

  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 ≤ 5/6 in the attention subscale of the Montreal Cognitive Assessment to detect attentional impairment as defined by a Test of Attentional Performance of Zimmermann and Fimm < 5th percentile in at least one of the subscales of the test

  4. 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 visuospatial/executive subscale of the Montreal Cognitive Assessment to detect executive impairment as defined by an abnormal result in one of the following test : 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 )

  5. 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]

    sensitivity and specificity of a score ≤ 4/5 in the attention subscale of the Montreal Cognitive Assessment to detect attentional impairment as defined by a free and cued selective reminding test, 16 items, B version Z-score ≤ -1,65 (in at least one of the subscales)
