Neurodegenerative diseases are a group of pathologies that cause severe disability due to motor and cognitive limitations. In particular, cognitive impairment is a growing health and socioeconomic problem which is still difficult to deal with today. As there are no pharmacologically effective treatments for cognitive deficits, scientific interest is growing regarding the possible impacts of healthy lifestyles on them. In this context, physical activity is gaining more and more evidence as a primary prevention intervention, a nonpharmacological therapy and a rehabilitation tool for improving cognitive functions in neurodegenerative diseases. In this descriptive overview we highlight the neurobiological effects of physical exercise, which is able to promote neuroplasticity and neuroprotection by acting at the cytokine and hormonal level, and the consequent positive clinical effects on patients suffering from cognitive impairment.

Background: Three studies assessed the (a) effectiveness of verbal instructions presented via technology in helping persons with moderate Alzheimer's disease perform daily activities and (b) impact of activity engagement on mood. Methods: The 3 studies targeted coffee preparation with 2 women, use of make-up with 2 women, and use of make-up and tea preparation with 3 women. Intervention effects on activity performance were assessed through nonconcurrent multiple baseline designs across participants or multiple baseline designs across activities. The impact of activity on mood was assessed by recording indices of happiness during activity trials and parallel nonactivity periods. Results: Verbal instructions presented via technology were effective in helping all participants perform the target activities. The participants also showed mood improvement (ie, increases in indices of happiness) during the activity. Conclusion: These results suggest that the approach reported may be a useful strategy for helping persons with Alzheimer's disease.
Huntington's disease (HD) is an inherited neurodegenerative disorder characterised by motor impairment, cognitive decline and psychiatric disorders. Dysphagia is a pathologic condition that increases morbidity and mortality of the affected people. Our aim was to evaluate dysphagia in a group of HD patients in view of motor, cognitive and functional decline. Thirty-seven genetically confirmed HD patients were submitted to clinical evaluations of swallowing. Bedside Swallowing Assessment Scale (BSAS) was used. Dysphagia Outcome and Severity Scale (DOSS) was applied for a preliminary classification of swallowing difficulties. All patients were also evaluated by the Unified Huntington's Disease Rating Scale (UHDRS). A group of 39 controls comparable for sex and age were recruited for BSAS scores normalisation. The BSAS scores indicated that in our HD cohort, 32.4% presented relevant or severe dysphagia. The DOSS levels were significantly correlated with main clinical features, such as age, disease duration and motor impairment, with special regard to lingual protrusion ability, dysarthria and bradykinesia. The total functional capacity (TFC) and cognitive scales did not show significant correlation with DOSS levels. The results of clinical examination of swallowing indicated that dysphagia is a prevalent motor symptom of HD.
Gymnastics athletes are exposed to a high risk of injury, but also of developing musculoskeletal pain. These data are still little investigated in the available scientific literature. An online survey was distributed to 79 professional athletes who practiced artistic and rhythmic gymnastics. The survey collected demographic and anthropometric data, information about the sport practice, the training sessions, the prevalence of musculoskeletal pain gymnastics-related, and lifestyle habits. Musculoskeletal pain had a high prevalence, involving 65 of 79 athletes (82.3%). A significant correlation was found between musculoskeletal pain and the duration of sports practice, both for general pain (p = 0.041) and for specific districts: right wrist pain (p = 0.031), left wrist pain (p = 0.028), right shoulder (p = 0.039), left hip (p = 0.031), right thigh (p = 0.031), and left knee (p = 0.005). Another statistical association was found between right wrist pain and BMI (p = 0.001), and hip pain and BMI (p = 0.030). Hours spent in a sitting position were also correlated with the incidence of pain (p = 0.045). Wrist pain and right shoulder pain had a statistically significant association with the age of the athletes (right wrist pain: p = 0.038; left wrist pain: p = 0.004; right shoulder pain: p = 0.035). The more the gymnasts practice this sport, the more likely they are to develop musculoskeletal pain. Increased age and a higher BMI, as well as daily prolonged sitting position, seem to be potential risk factors for the onset of musculoskeletal pain. Future studies could plan training strategies aimed at preventing musculoskeletal pain associated with gymnastics, in order to promote its further spread.
