Abstract
Senile dementia, also known as dementia, is the mental deterioration which is associated with aging. It is characterized by a decrease in cognitive abilities, inability to concentrate, and especially the loss of higher cerebral cortex function, including memory, judgment, abstract thinking, and other loss of personality, even behavior changes. As a matter of fact, dementia is the deterioration of mental and intellectual functions caused by brain diseases in adults when they are mature, which affects the comprehensive performance of life and work ability. Most dementia cases are caused by Alzheimer’s disease (AD) and multiple infarct dementia (vascular dementia, multi-infarct dementia). Alzheimer’s disease is characterized by atrophy, shedding, and degenerative alterations in brain cells, and its occurrence is linked to age. The fraction of the population with dementia is smaller before the age of 65, and it increases after the age of 65. Since women live longer than men, the proportion of women with Alzheimer’s disease is higher. Multiple infarct dementia is caused by a cerebral infarction, which disrupts blood supply in multiple locations and impairs cerebral cortex function. Researchers worldwide are investigating ways to prevent Alzheimer’s disease; however, currently, there are no definitive answers for Alzheimer’s prevention. Even so, research has shown that we can take steps to reduce the risk of developing it. Prospective studies have found that even light to moderate physical activity can lower the risk of dementia and Alzheimer’s disease. Exercise has been proposed as a potential lifestyle intervention to help reduce the occurrence of dementia and Alzheimer’s disease. Various workout modes will be introduced based on various physical conditions. In general, frequent exercise for 6–8 weeks lessens the risk of dementia development.
Highlights
Introduction published maps and institutional affilDementia is not a single disease, but a group of symptoms
The results show that physical activity and exercise can improve the cognitive performance of people with cognitive impairment to some extent [33,34,35], but it is not clear which combination of frequency, intensity, duration, and type of exercise has a better effect on cognitive performance
Studies have established a link between leisure-time physical exercise and the risk of all-cause dementia or Alzheimer’s disease (AD), with the AD risk curve tending to flatten at higher levels of activity [68]
Summary
Most patients fall into this category, among which the following three are the most common. The most obvious symptoms are memory decline, problems in the identification of time, place, and people, and more than two kinds of cognitive dysfunction, which is a progressive degradation and irreversible. It is a neurodegenerative disease in which nerve cells in the brain are damaged [5]. As the second most common degenerative dementia, in addition to the cognitive dysfunction, in early stage, patients may experience stiffness, hand shaking, walking instability, and repeatedly unexplained fall phenomenon. Drugs have not been proven to have a neuroprotective effect on dementia, the growing body of literature demonstrates that long-term, regular exercise has significant benefits on cognition, dementia risk, and dementia progression [11,12]
