RBANS analysis of verbal memory in multiple sclerosis

Area of Science:

• Neuropsychology
• Neurology

Background:

• Subcortical neurodegenerative diseases like Parkinson's disease (PD) and multiple sclerosis (MS) often impair verbal memory recall.
• Previous studies suggest memory retrieval can be enhanced by recognition or organizational strategies, but methodological issues raise concerns.

Purpose of the Study:

• To investigate verbal memory performance in patients with multiple sclerosis (MS) using a standardized methodology.
• To compare memory patterns in MS with previously established patterns in Parkinson's disease (PD).

Main Methods:

• Utilized the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) verbal memory subtests.
• Calculated Z scores for Story Memory, List Learning, Story Recall, List Recall, and List Recognition relative to age groups.
• Analyzed pairwise score differences to assess memory recall and recognition patterns.

Main Results:

• Multiple sclerosis patients exhibited better recall for stories compared to lists.
• Patients with MS demonstrated superior List Recognition performance over List Recall.
• These findings contrast with Parkinson's disease patients, who did not show enhanced story recall or recognition over recall.

Conclusions:

• Multiple sclerosis patients display unique verbal memory profiles, differing from Parkinson's disease patients.
• The observed memory differences may relate to distinct neuropathological impacts, particularly in entorhinal regions.
• Memory impairments in most MS patients appear mild and potentially amenable to intervention.
