Background: The effect multiple sclerosis (MS) has on the social functioning and integration of patients has been recently considered as an important factor of the disease., Objectives: To assess social participation of MS patients with regard to demographic and disease-related variables., Material and Methods: The study comprised 201 MS patients: 140 women, 61 men, aged 24-69 years. The World Health Organization Disability Assessment Schedule (WHODAS 2.0) was applied to assess the aspects of social functioning and the Beck Depression Inventory (BDI) was applied to evaluate the level of depression. Disease duration, degree of disability in Expanded Disability Status Scale (EDSS), most disabling symptoms and type of treatment were determined. WHODAS 2.0 scores (total and within particular domains) and their relationships with age, gender, disease-related variables and level of depression were analyzed., Results: The results of WHODAS 2.0 for 27.4% of patients exceeded the 90th percentile compared to the population norms (with the highest scores for "getting around" and "participation in society" domains). The results of BDI and WHODAS 2.0 were strongly correlated (p < 0.001; β = 0.73) and mobility impairment was related to both of them (p < 0.001; β = -0.12 and 0.25, respectively). Other disabling symptoms were associated with scores in domains "understanding and communicating", "getting around" and "participation in society"., Conclusions: Social participation of the MS patients is affected by the impact of disease and associated with depression. Particular symptoms of neurological deficit (motor and visual impairment, fatigue) influence social functioning more than general disease-related variables.

Background The aim of the study was to assess microstructural changes within strategic brain regions in multiple sclerosis (MS) patients, using diffusion tensor imaging (DTI), with regard to various aspects of disability. Material and methods The study comprised 50 patients with relapsing-remitting MS (37 women, 13 men, mean age 36.4 yrs) and 27 age- and sex-matched controls. Using DTI, fractional anisotropy (FA) and apparent diffusion coefficient (ADC) values were obtained within corpus callosum (CC), both thalami (TH) and middle cerebellar peduncles (MCP). Disability was assessed using Expanded Disability Status Scale (EDSS), MS Functional Composite (MSFC), Symbol Digit Modalities Test (SDMT) and Fatigue Severity Scale (FSS). DTI indices were compared between the patients and controls and in the MS group - referred to disability measures. Results Significant decrease in FA and increase in ADC within CC and both TH were found in MS patients compared to the controls. DTI indices within CC and TH correlated significantly with SDMT score, and within TH and MCP - with MSFC manual dexterity measure. Conclusions Changes in DTI measures in normal appearing white and grey matter in the MS patients indicate subtle alterations of the tissue integrity. An occult damage to the strategic brain regions may contribute to various aspects of disability due to MS. [ABSTRACT FROM AUTHOR]
