Memory in Polish multiple sclerosis patients - correlations with mood and fatigue

Area of Science:

• Neuroscience
• Clinical Psychology
• Rehabilitation Medicine

Background:

• Multiple Sclerosis (MS) is a chronic neurological disease affecting cognitive functions, particularly memory.
• Understanding the factors influencing memory deficits in MS is crucial for patient management and rehabilitation.
• Previous research indicates potential links between MS, cognitive impairment, and quality of life indicators.

Purpose of the Study:

• To assess memory functions in Polish patients diagnosed with multiple sclerosis (MS).
• To investigate the associations between memory performance and clinical aspects of MS, including neurological status, mood, fatigue, and employment.
• To identify predictors of memory impairment in the MS population.

Main Methods:

• Employed the California Verbal Learning Test (CVLT) and Brief Visuospatial Memory Test-revised (BVMT-R) to evaluate memory.
• Utilized the Hospital Anxiety and Depression Scale and Modified Fatigue Impact Scale to assess psychological and fatigue symptoms.
• Compared 100 MS patients with 150 healthy participants (HP), analyzing correlations with clinical data and employment status.

Main Results:

• MS patients demonstrated significantly poorer performance on both verbal and visuospatial memory tests compared to healthy controls.
• Secondary progressive MS patients exhibited the lowest memory scores.
• Worse neurological status was identified as the sole clinical predictor of memory deficits, while fatigue and depression showed significant group differences but not direct memory association.

Conclusions:

• Memory impairment is a significant issue in multiple sclerosis (MS) patients, directly influencing their employment status.
• While fatigue and depressive symptoms are common in MS, they were not found to be direct predictors of memory status in this study.
• Neurological status is a key factor associated with memory disturbances in individuals with MS.
