BackgroundMultiple sclerosis (MS) is an inflammatory demyelinating central nervous system disease with diverse clinical manifestations. The present study aimed to compare the psychiatric outcomes of MS patients with full ambulatory versus impaired ambulatory function and identify the potential risk factors for disability in MS. Seventy MS patients were classified into two groups based on their Expanded Disability Status Scale (EDSS) scores, Group A: full ambulatory (EDSS ≤ 4.5) (N = 48), Group B: impaired ambulatory (EDSS ≥ 5) (N = 22). All participants were evaluated by the Socioeconomic Scale, Hamilton Anxiety Scale, Hamilton Depression Scale, Brief Psychiatric Rating Scale, and The Pittsburgh Sleep Quality Index.ResultsIn the total cohort (N = 70), females represented (77.1%). The mean age was 31.16 ± 6.46, the mean age of onset was 26 ± 6.083, and the mean disease duration was 5.33 ± 3.653 years which was less in Group A than in Group B. Relapsing–remitting multiple sclerosis (RRMS) was the most common presentation (80%), representing 93.6% of Group A. Group A reported more severe depression and anxiety, while Group B had more poor sleep quality. Correlation analysis showed increased relapses, progressive-relapsing multiple sclerosis (PRMS), cervical or dorsal plaques, sensory or motor manifestations, and precipitancy increased disability, while RRMS type decreased disability.ConclusionsFull ambulatory MS patients had high anxiety and depression, while impaired ambulatory MS patients had poor sleep quality. Associated factors for disability were frequent relapses, plaque location, MS subtype, sphincter, and sensory symptoms.Trial registration clinicaltrials.gov, NCT05029830.
