Patients with multiple sclerosis often misjudge their cognitive abilities. While global self-assessments don't match test results, specific task perceptions correlate, though often underestimated. Factors like fatigue and depression influence these perceptions.

Area of Science:

  • Neuroscience
  • Psychology
  • Clinical Medicine

Background:

  • Multiple sclerosis (MS) frequently impacts cognitive functioning.
  • Understanding the discrepancy between perceived and objective cognitive performance in MS is crucial for patient care.
  • Previous research indicates a complex relationship between self-awareness and actual cognitive deficits in neurological conditions.

Purpose of the Study:

  • To investigate the relationship between perceived and objective cognitive functioning in patients with multiple sclerosis.
  • To identify factors that predict perceived cognitive functioning in this population.
  • To clarify how patients with MS perceive their cognitive abilities in daily life and on specific tasks.

Main Methods:

  • A cohort of 221 patients with multiple sclerosis was assessed.

  • Objective cognitive functioning was measured using a comprehensive test battery.
  • Perceived cognitive functioning was evaluated through self-reported global assessments and specific task performance perceptions.

    • Main Results:

    • Patients' global perceived cognitive functioning was unrelated to objective performance on the full cognitive test battery.
    • Perceived performance on specific cognitive tasks correlated with objective performance, but patients tended to underestimate their abilities.
    • Depression, anxiety, fatigue, and disability level predicted global perceived cognitive functioning, not objective cognitive performance.

    Conclusions:

    • In multiple sclerosis, global self-perceptions of cognitive function do not align with objective measures.
    • Specific task-based self-perceptions in MS patients show some correlation with objective performance, albeit with underestimation.
    • Clinical interpretation of patients' cognitive concerns in MS should consider psychological and physical factors, as objective performance is not the sole determinant of perceived functioning.
