The CI is more common in advanced stages of the disease, although it can occur at any time. Exceptionally, CI is the first manifestation of MS, and these patients develop a progressive cognitive deterioration from the beginning of the disease. The presence of cognitive and psychological difficulties in people with MS contributes more to withdrawal from work and unemployment than physical disability. Įpidemiological studies reported frequencies of cognitive impairment (CI) in patients with MS between 40 and 70% of subcortical profiles. īesides, motor and autonomic symptoms, MS was verified to have a higher risk of developing a wide range of psychobehavioral disorders, such as depression, anxiety, bipolar disorder, sleep disorders, schizophrenia, and other psychotic disorders, all of which share cognitive decline. Multiple sclerosis (MS) is an inflammatory and immune-mediated disease of the central nervous system characterized by the development of focal demyelination and neuronal injury in functionally or anatomically related regions involved in cognitive processing such as the white matter, the cerebral cortical and deep gray matter, and the hippocampus. As for the profile of cognitive dysfunction in patients with MS, the domains most frequently failed by the patients were memory, attention, visuospatial learning, and language. The longer the disease duration and the higher the EDSS, the lower the MoCA score and the higher the education level, the higher the MoCA score. MoCA scale has optimal psychometric properties for routine clinical use in patients with MS, even in those with mild functional disability. MoCA was positively correlated with education level but negatively with EDSS and disease duration. CI was higher in those with a longer duration of illness and a high EDSS. Total MoCA scores were lower in patients with CI versus those with intact cognition. MS patients show low total MoCA score than the controls. The Expanded Disability Status Scale (EDSS) was used to assess the degree of disability, and the Montreal Cognitive Assessment (MoCA) scoring system was used to assess cognitive function. This is a case–control study of fifty patients with MS who met the revised 2017 Mc Donald Criteria and fifty age- and sex-matched healthy subjects. We aim to study the influence of MS on cognitive changes. About 40–70% of patients with multiple sclerosis (MS) develop cognitive impairment (CI) throughout their life.
