Abstract

Background

To compare the frequency and pattern of cognitive impairment in neuromyelitis optica spectrum disorder (NMOSD) and multiple sclerosis (MS) patients.

Results

Twenty NMOSD and forty MS patients were included. Clinical and detailed neuropsychological assessment was done using frontal assessment battery and Kolkata cognitive battery supplemented with additional standard tests for different domains of cognitive functions. Domain wise tests were performed and compared. 15/20 (75%) NMOSD and 32/40 (80%) MS patients had cognitive impairment (p = 0.65). Executive function, verbal fluency, information processing speed, visuo-constructional ability, attention, complex calculation, and memory were more commonly involved in NMOSD in decreasing order. Compared to MS, the pattern was similar except that verbal fluency was more impaired in NMOSD. Expanded Disability Status scale (EDSS) correlated with cognitive involvement in NMOSD (p = 0.02) as against MS.

Conclusions

Executive function, verbal fluencies, and information processing speed were more affected compared to visual and verbal memory in NMOSD patients. The pattern of cognitive performance was similar in the MS group, even though clinical and radiological characteristics and pathophysiology is different, suggesting similar brain involvement.
