Effect of Tai-chi on balance, mood, cognition, and quality of life in women with multiple sclerosis: A one-year prospective study.

INTRODUCTION: One of the most debilitating problems encountered by people with multiple sclerosis (MS) is the loss of balance and coordination. Our study aimed to comprehensively evaluate the effectiveness of one year of Tai-chi exercise in patients with MS using both subjective and objective methods, including posturography. METHODS: This was a single-group longitudinal one-year study performed from the 1st of January 2019 to the 1st of January 2020. The primary outcomes of interest were the Mini-Balance Evaluation Systems Test (Mini-BESTest) and static posturography measures as objective methods to detect subtle changes associated with postural control/balance impairment. Secondary outcomes were measures of depression, anxiety, cognitive performance, and quality of life. All objective and subjective parameters were assessed four times: at baseline, and after three, six and 12 months of regular Tai-chi training. The difference was calculated as a subtraction of baseline values from every timepoint value for each measurement. If the normality test was passed, parametric one-sample t-test was used, if failed, Wilcoxon signed ranks test was used to test the difference between the baseline and each timepoint. Alpha was set to 0.017 using Bonferroni correction for multiple comparisons. RESULTS: Out of 25 patients with MS enrolled, 15 women with MS (mean age 44.27 years) were included for statistical analyses after completing the 12-month program. After 12 months, significant improvements were found in all objective balance and gait tests: Mini-BESTest (p<0.001), static posturography measures (total area of the centre of foot pressure - TA; p = 0.015), 25 Feet Walk Test (25FWT; p = 0.001), anxiety (Beck Anxiety Inventory - BAI; p = 0.005) and cognition tests (Paced Auditory Serial Addition Test - PASAT; p = 0.003). Measures of depression (Beck Depression Inventory - BDI; p = 0.071), cognition (Symbol Digit Modalities Test - SDMT; p = 0.079), and health-related quality of life (European Quality of Life 5-Dimensions Questionnaire - EQ-5D-5L; p = 0.095) showed a trend of improvement but were not significant, which could be the result of a small sample and increased bias due the type II error. CONCLUSION: According to these preliminary results, this study indicates the possible beneficial effects of long-term Tai-chi training on patients with MS. Although these findings need to be confirmed by further studies with a larger sample of participants of both genders and require more rigorous randomized controlled trials (RCT) design, our findings support the recommendation of regular and long-term Tai-chi exercise in patients with MS.

Combined central and peripheral demyelination - one-year follow-up of patient with co-incidence of multiple sclerosis and multifocal acquired demyelinating sensory and motor neuropathy - A Case Report.

Combined central and peripheral demyelination (CCPD) is a rare autoimmune neurologic disease, characterized by immune-mediated damage of myelin sheath at central and peripheral levels of the nervous system. The current knowledge about this disorder is only limited, mainly due to the low incidence of the disease. According to previous studies, CCPD has a very heterogeneous course, insufficient therapeutic response, and an unfavorable prognosis. We report on the 37-year-old patient with a coincidence of demyelinating lesions in the brain fulfilling current McDonald's diagnostic criteria for multiple sclerosis, as well as the presence of an atypical variant of chronic inflammatory demyelinating polyneuropathy (CIDP) - multifocal acquired demyelinating sensory-motor neuropathy (MADSAM), as a subtype of combined central and peripheral demyelination (CCPD).

Brain volume loss in multiple sclerosis is independent of disease activity and might be prevented by early disease-modifying therapy.

INTRODUCTION: Neurodegeneration is likely to be present from the earliest stages of multiple sclerosis (MS). MS responds poorly to disease-modifying treatments (DMTs) and leads to irreversible brain volume loss (BVL), which is a reliable predictor of future physical and cognitive disability. Our study aimed to discover the relationship between BVL, disease activity, and DMTs in a cohort of patients with MS. MATERIAL AND METHODS: A total of 147 patients fulfilled our inclusion criteria. Relevant demographic and clinical data (age, gender, time of MS onset, time of treatment initiation, DMT characteristics, Expanded Disability Status Scale (EDSS), number of relapses in the last two years prior to MRI examination) were correlated with MRI findings. RESULTS: Patients with progressive MS had significantly lower total brain and grey matter volumes (p = 0.003; p < 0.001), and higher EDSS scores (p < 0.001), compared to relapsing-remitting patients matched by disease duration and age. There was no association between MRI atrophy and MRI activity (c2 = 0.013, p = 0.910). Total EDSS negatively correlated with the whole brain (rs = -0.368, p < 0.001) and grey matter volumes (rs = -0.308, p < 0.001), but was not associated with the number of relapses in the last two years (p = 0.278). Delay in DMT negatively correlated with whole brain (rs = -0.387, p < 0.001) and grey matter volumes (rs = -0.377, p < 0.001). Treatment delay was connected with a higher risk for lower brain volume (b = -3.973, p < 0.001), and also predicted a higher EDSS score (b = 0.067, p < 0.001). CONCLUSIONS: Brain volume loss is a major contributor to disability progression, independent of disease activity. Delay in DMT leads to higher BVL and increased disability. Brain atrophy assessment should be translated into daily clinical practice to monitor disease course and response to DMTs. The assessment of BVL itself should be considered a suitable marker for treatment escalation.
