People living with MS (pwMS) are impacted physically, psychologically, and socially. Illness perception refers to a person's cognitive and emotional representations of their disease, which can impact their psychophysical well-being and treatment adherence.<\/jats:p>\n                  <jats:p>To assess the illness perception of pwMS and determine how it is impacted by cognitive dysfunction and fatigue.<\/jats:p>\n                  <jats:p>In this cross-sectional pilot survey study, the Brief Illness Perception Questionnaire (B-IPQ), Montreal Cognitive Assessment (MoCA-BR), Modified Fatigue Impact Scale (MFIS-BR), and Multiple Sclerosis Quality of Life Questionnaire (MSQOL-54) were used. Demographic and clinical data, as well as the Expanded Disability Status Scale (EDSS), were collected.<\/jats:p>\n                  <jats:p>A total of 30 RRMS patients (66.7% of female subjects, with a mean age of 36.8\u2009\u00b1\u20091.8 years) were enrolled. The mean score on the B-IPQ scale was of 30.2\u2009\u00b1\u20098.9 points, with 40% presenting a threat perception of the disease. No significant correlation was observed between cognitive performance and illness perception (r\u2009=\u2009\u22120.058; p\u2009=\u20090.761). However, significant correlations were found between illness perception and all fatigue domains (total: r\u2009=\u20090.578; p\u2009=\u20090.001; physical: r\u2009=\u20090.594; p\u2009=\u20090.001; psychosocial: r\u2009=\u20090.672; p\u2009&lt;\u20090.001), except the cognitive domain (r\u2009=\u20090.360; p\u2009=\u20090.051). The EDSS and MSQOL-54 scores also demonstrate significant correlations with illness perception (EDSS\u2009=\u20092.30; p\u2009=\u20090.034; MSQOL-54 physical: r\u2009=\u2009\u22120.776;

of life, and disability levels, but it does not appear to be affected by
