Depression and dementia disorders are associated with cardiovascular and somatic co-morbidities, which are closely related to physical inactivity. Physical exercise can improve these cardiovascular and metabolic co-morbidities. In addition, physical activity and training are effective in the prevention and treatment of affective and cognitive disorders. These effects were also found in the elderly. Because of limited effectiveness and tolerance of pharmacological standard treatment options, the relevance of physical exercise as a therapeutic tool should be recognized. In a multifactorial way psychological, neurobiological as general somatic (e.g. cardiovascular and metabolic) aspects are involved in the effectiveness of exercise on brain structure and function. Hence assessment of exercise habits and individual recommendations for physical activity should be implemented as a standard procedure in the therapy of affective disorders and dementia, beginning as early as possible but also at higher ages.

Abstract Background Few previous cohorts have studied the different type of physical activities and the degree of cognitive decline. The objective of this work was to analyze the leisure, domestic and professional activities with mild and moderate cognitive disorders in older people living in community. Methods The study used data from the longitudinal and observational study, FrèLE (FRagility: Longitudinal Study of Expressions). The collected data included: socio-demographic variables, lifestyle, and health status (frailty, comorbidities, cognitive status, depression). Cognitive decline was assessed by using: MMSE (Mini-Mental State Examination) and MoCA (Montreal Cognitive Assessment). MoCA was used with two cut-offs (26 and 17) so as to define mild and moderate cognitive disorders Physical activity was assessed by the PASE (Physical Activity Scale for the Elderly), structured in three sections: leisure, domestic and professional activities. Spline and proportional hazards regression models (Cox) were used to estimate the risk of cognitive disorders. Results At baseline, 1623 participants were included and the prevalence of cognitive disorders was 6.9% (MMSE) and 7.2% (MoCA), mild cognitive disorders was 71.3%. The mean age was 77 years, and 52% of the participants were women. After a 2 years long follow-up, we found 6.9% (MMSE) and 6% (MoCA) cognitive disorders on participants. Analyses showed that domestic activities were associated to cognitive decline (HR = 0.52 [0.28-0.94] for MMSE and HR = 0.48 [0.28-0.80] for MoCA). No association were found with leisure and professional activities, and no spline were significant with mild cognitive disorders. Conclusions Analysis showed a relationship between cognitive disorders and type of physical activity, thanks to the use of specific questionnaire of elderly and two global test of cognition. These findings will contribute to the debate on the beneficial effects of physical activity on cognition. Key messages This work allowed to compare two test of cognition and their link with physical activity. It contributes to the debate on the beneficial effects of physical activity on cognition. The work allowed us to see the effect of the different types of physical activity and the impact of the statistical method on the results.

Age Related Changes

Sarcopenia is a complex and multifactorial disease that includes a decrease in the number, structure and physiology of muscle fibers, and age-related muscle mass loss, and is associated with loss of strength, increased frailty, and increased risk for fractures and falls. Treatment options are suboptimal and consist of exercise and nutrition as the cornerstone of therapy. Current treatment principles involve identification and modification of risk factors to prevent the disease, but these efforts are of limited value to the elderly individuals currently affected by sarcopenia. The development of new and effective therapies for sarcopenia is challenging. Potential therapies can target one or more of the proposed multiple etiologies such as the loss of regenerative capacity of muscle, age-related changes in the expression of signaling molecules such as growth hormone, IGF-1, myostatin, and other endocrine signaling molecules, and age-related changes in muscle physiology like denervation and mitochondrial dysfunction. The present paper reviews regenerative medicine strategies that seek to restore adequate skeletal muscle structure and function including exogenous delivery of cells and pharmacological therapies to induce myogenesis or reverse the physiologic changes that result in the disease. Approaches that modify the microenvironment to provide an environment conducive to reversal and mitigation of the disease represent a potential regenerative medicine approach that is discussed herein.

Older Men And Women

Habitual exercise provides protection against fatal coronary heart disease, extends longevity, and enhances quality of life. National surveys show less physical activity in older men and women compared with middle-aged and younger persons; older women are particularly sedentary. Although there are still few longitudinal studies on exercise and physical activity in older individuals, the data support a positive relationship between physical activity and health and function in older individuals. The data further show that with regular physical activity, health and physical fitness are maintained or even increased over time in older individuals. Studies on physical activity requirements for beneficial health effects in the elderly are reviewed and presented, and exercise recommendations for older individuals are given.

Different Levels

The mechanisms underlying ADHD are complex and can be defined at different levels. Cognitive deficits are often part of the disorder, including problems in executive functioning, reward processing, and timing deficits. Alterations have also been reported in brain structure and function in people with the disorder. ADHD is known to be a highly heritable, multifactorial disorder, in which genetic factors—often in combination with environmental factors—are risk factors for disease onset. Early research at the genetic level has implicated monoaminergic neurotransmission, following the serendipitous finding that methylphenidate, a dopamine and noradrenaline transport inhibitor, treats ADHD symptoms. The current models to explain brain malfunctioning in ADHD indeed centre around these monoamine systems. In addition to dopamine, noradrenaline, and (to a lesser extent) serotonin, also glutamate, histamine, and the nicotinic acetylcholinergic system seem to be involved in ADHD aetiology. In the coming years, genetic research is expected to uncover more of the mechanisms underlying ADHD, hopefully resulting in improved treatment options.

Sarcopenia, the loss of muscle mass and function with ageing, is a multifactorial condition that slowly develops over decades and becomes a significant contributor to disability in the older population. Malnutrition and alterations in the muscle anabolic response to nutritional stimuli have been identified as potentially preventable factors that may significantly contribute to sarcopenia. In the present article we review the most recent findings regarding the role of nutritional factors in the development, prevention and treatment of sarcopenia. Specifically, we focus on the nutritional needs of the elderly; the age-related changes in the response of muscle protein metabolism to feeding and to the endogenous hormones released during feeding; and the role played by the splanchnic tissues in the response of muscle proteins to feeding. Finally, we review the issues relative to the potential use of nutritional therapies, including supplementation, for the prevention and treatment of sarcopenia.

Studies on the effectiveness of physical exercise to treat and/or prevent mental disorders are essential and particularly appropriate, given the rapid growth of the elderly population and the consequent increase in the prevalence of neurodegenerative diseases. The onset of neurodegenerative diseases is subtle, and progression is irreversible, as there is still no cure capable of stopping them permanently. Therefore, we should not underestimate these diseases and should immediately begin to combine the treatment with physical activity adapted to specific needs. Indeed, it is well known that physical activity has positive effects on mobility, autonomy, and functional capacity, improving not only cognitive functions, but also reducing the risk of developing dementia. Despite several studies in this field, to date there are no specific and effective protocols that promote physical exercise in people with dementia. Based on this evidence, the aim of the present work was to verify whether an adapted physical exercise regimen could promote the maintenance of psychomotor functions in elderly subjects and, therefore, delay the irreversible effects of combinations of dementia and other pathologies associated with aging. Our results clearly show that exercise is very effective in improving psychomotor functions and delaying the progress of neurodegenerative diseases in humans, since we observed that the subjects maintained their cognitive skills after 8 months of physical activity, moreover, two patients presented an amelioration. Based on the results obtained, we recommend that the motor practice, in any chosen form, be considered an integral part of prevention programs based on an active lifestyle in older people. Future studies will be necessary to establish how long lasting the benefits of a specific physical activity are and whether they are enough to delay cognitive decline.
