Motor neuron diseases (MNDs) are a group of relatively rare, progressive neurodegenerative conditions (with amyotrophic lateral sclerosis/ALS being the most common) characterized by degeneration of upper and lower motor neurons leading to motor and extra motor symptoms. The etiology of MND is believed to involve complex interactions of environmental, lifestyle, and genetic factors, but so far only a few convincing risk factors have been established. Several putative risk factors associated with sporadic cases have been suggested, including repetitive blows to the head and traumatic brain injury. ALS is considered a sporadic disorder in 90% of cases. The incidence of ALS in the United States is 1.5 to 2.2 per 100.000, but varies significantly by age, sex, and race. The incidence of ALS generally increases with age and peaks during the seventh decade of life. There is not a large number of relevant studies for reliable conclusions about the connection between sports and BMN. However, there is increasing interest in the role of contact sports (eg, American football and rugby) following the diagnosis of BMN in several high-profile professional athletes. Several case-control studies have found an increased risk of MND among people who engage in strenuous physical activity, but other studies of this type did not find this risk (association) or the association was negative. Several other studies have shown an increased risk of BMN with traumatic brain injury, while others have found no association. The risk of MND varies depending on the type of sport played. For many individual sports, no increased risk of BMN was observed, including cricket, basketball, tennis, swimming, hockey, volleyball, badminton, field hockey, sailing, rowing, diving and skiing. However, several meta-analyses have shown a 1.3 to 1.7 times higher risk of MND in athletes who suffer a head injury, compared to the general population. Experience shows that exercise can be physically and psychologically important for people with ALS. Although the results so far do not provide clear conclusions regarding physical therapy or/and exrecise regimens to maintain function and quality of life in people with ALS, we can say, for sure, that moderate exercise is not harmful. Regarding the type of exercise, moderate intensity and not very high frequency (two sessions per week), combining strength and aerobic resistance, may be the best option to see improvements in ALS patients and prevent fatigue that further impairs their quality of life.Key words: amyotrophic lateral sclerosis – sports – physical therapy

Background: The COVID-19 pandemic has generated significant symptoms of stress, anxiety, and depression among health care workers, which can negatively affect the health and well-being of individuals. Although the WHO stressed the importance of nurturing mental health in the context of the COVID-19 pandemic, a more significant response focused on this area was still lacking in most countries. Objective: The aim of the study was to examine the differences in the levels of depression, anxiety, and stress in healthcare professionals in relation to exposure to contact with COVID-19 positive patients, as well as to examine the differences and correlation of sociodemographic characteristics of health workers in the experience of symptoms of depression, anxiety and stress. Methods: The research included 266 respondents, and it used a socio-demographic questionnaire and the DASS-21 scale. Mann-Whitney U tests, Kruskal-Wallis test and Spearman correlation coefficient were used in data processing. Results: The prevalence of high to extremely high symptoms of depression was reported in 45.49% of employees, anxiety 63.91% and stress 23.22%. Those who have been in continuous contact with COVID-19 positive patients, or 27.07%, report experiencing high or extremely high symptoms of depression, 36.60%, high to extremely high symptoms of anxiety, and 22.18% high to extremely high symptoms of stress. Discussion: The degree of self-care and family care, education level, and work experience were found to be a statistically significant factor in experiencing symptoms of depression, anxiety, and stress. Workers who were more in contact with COVID19 patients reported a higher degree of symptom on the DASS-21 scale. Those employees with more work experience had previously encountered similar situations of uncertainty and pressure, had better developed defense mechanisms, and showed less pronounced symptoms. A higher level of education often implies a higher degree of involvement in active treatment around each patient, which results in more responsibility and pressure in a given situation. Conclusion: High levels of stress, anxiety and depression in healthcare workers can lead to repercussions in their work with patients. Therefore, the mental health of health workers should be put in focus, as a very important part of the public health problem during the COVID19 pandemic.
