Self-reported executive dysfunction, neuropsychological impairment, and functional outcomes in multiple sclerosis

Area of Science:

• Neuroscience
• Clinical Psychology
• Rehabilitation Medicine

Background:

• Cognitive deficits are prevalent in multiple sclerosis (MS).
• The link between self-reported cognitive issues and objective performance in MS is not always clear.
• Executive functions are frequently affected in MS, impacting daily life.

Purpose of the Study:

• To investigate the relationship between subjective complaints of dysexecutive syndrome, objective neuropsychological performance, and daily living activities in people with MS.
• To determine if self-reported executive dysfunction predicts cognitive deficits and functional impairment in MS.

Main Methods:

• A study involving 42 individuals with MS and 13 healthy controls.
• Assessment of subjective complaints using the Frontal Systems Behavior Scale (FrSBe).
• Neuropsychological testing to evaluate cognitive performance.
• Self-reported measures of activities of daily living.

Main Results:

• Subjective complaints of impairment, as measured by the FrSBe, were a significant predictor of neuropsychological deficits.
• Self-reported executive dysfunction also predicted poorer adaptive functioning in daily life.
• The findings highlight a strong correlation between perceived and actual cognitive and functional impairments in MS.

Conclusions:

• Subjective complaints of dysexecutive function in MS are a potent indicator of underlying cognitive and functional impairment.
• These findings have implications for improving the assessment and management of cognitive issues in MS.
• Clinical practice should consider subjective reports as valuable diagnostic information in MS patients.
