Although it is predominantly a muscular disease, impairments in the central nervous system in patients with facioscapulohumeral muscular dystrophy (FSHD) have been described in the literature.
OBJECTIVES: To describe the cognitive profile of patients with FSHD and to correlate the impairments found with clinical variables and quality of life.
METHODS: Cross-sectional and case-control study that evaluated FSHD patients using a series of cognitive assessments (Mini-Mental State Examination - MMSE, Montreal Cognitive Assessment - MoCA, verbal fluency with phonological restriction - FAS, categorical verbal fluency - FAS-cat, trail-making test - TMT, and Rey's Verbal Auditory Learning Test); a neurological severity scale (Gardner-Medwin-Walton - GMWS); and a quality of life measurement tool (Medical Outcomes Study 36-Item Short-Form Health Survey).
RESULTS: Individuals with FSHD (13) and healthy controls (26) were paired by gender and age. Significant differences between case and control groups were found in MMSE, TMT A, and A7 (p≤0.05) and MOCA (p≤0.001) performances. A positive correlation was verified in long-term memory impairments and the age in which symptoms appear (r=-0.593, p=0.033). Regarding quality of life assessment, the emotional domain correlated to MEEM (r=0.657, p=0.015), TMT A (r=-0.601, p=0.030), and A7 (r=0.617, p=0.025) performances.
CONCLUSIONS: Individuals with FSHD presented mild impairments in the performance of tasks that involve attention, planning, and long-term memory functions. Those impairments were associated neither with the disease duration nor with its neurological severity.
