![]() ![]() Increased Physical Activity Can Prevent Cognitive DeclineĮpidemiological generational follow-up studies, case–control studies and systematic retrospective studies have all shown that the risk of Alzheimer’s disease, vascular dementia or overall dementia is reduced, regardless of the amount of physical activity, the amount of physical activity during leisure, the amount of total physical activity or the better level of fitness. According to a study, older adults who were physically active, even if it was low-intensity activity such as gardening or golf, had larger brains compared to those inactive seniors. Exercise enhances brain growth and prevents cognitive decline. Surprisingly, these are the same areas that respond to physical activity. The decline of the brain’s hippocampus and prefrontal cortex, which play important roles in memory formation and complex thinking, is a risk factor for Alzheimer’s disease. the greater the amount of physical activity, the better the prevention effect. Systematic review and meta-analysis studies confirm that the effects of exercise prevention of various types of dementia and Alzheimer’s disease show a dose response trend. Studies have shown that hydrogen peroxide oxidation(H 2O 2) damage in the body can cause the accumulation of amyloid beta-amyloid (Aβ) and alpha-synuclein (α-syn) in the cells of normally inactive people, which is not the case in endurance athletes. In addition, past studies, from the physiological and molecular biological levels of nerve cells, have provided favorable evidence that increased physical activity can prevent dementia in older people. Ĭase–control studies have suggested that increased physical activity can significantly reduce the risk of dementia in older people. Since the benefits of exercise in reducing the risk of atherosclerosis (cerebrovascular disease) are well established, exercise may have a more immediate beneficial effect on brain neuroplasticity and resilience to brain aging and neurodegeneration. Exercise can reduce the effects of atherosclerotic cerebrovascular disease to promote brain health. These atherosclerotic cerebrovascular mechanisms differ from neurodegeneration and age-related loss of neurofibril networks and synapses. Primary vascular dementia is common, and cerebrovascular small vessel diseases too (e.g., white matter osteoporosis and lacunar disease) seem to combine with neurodegenerative processes to cause dementia. Its characteristics are sudden deterioration of cognitive function, ups and downs, step-by-step degradation, slow movement, slow response, gait instability and mental symptoms. Dementia occurred in 25% of the cases after five years of surveillance. If a stroke victim survives, roughly 5% of survivors will develop dementia symptoms. Generally, vascular dementia occurs after stroke. ![]() Brain cell death caused by mental decline is the second leading cause of dementia. Vascular dementia is due to stroke or chronic cerebrovascular lesions, resulting in poor blood circulation in the brain. In general, frequent exercise for 6–8 weeks lessens the risk of dementia development. Various workout modes will be introduced based on various physical conditions. Exercise has been proposed as a potential lifestyle intervention to help reduce the occurrence of dementia and Alzheimer’s disease. Prospective studies have found that even light to moderate physical activity can lower the risk of dementia and Alzheimer’s disease. Even so, research has shown that we can take steps to reduce the risk of developing it. Researchers worldwide are investigating ways to prevent Alzheimer’s disease however, currently, there are no definitive answers for Alzheimer’s prevention. Multiple infarct dementia is caused by a cerebral infarction, which disrupts blood supply in multiple locations and impairs cerebral cortex function. Since women live longer than men, the proportion of women with Alzheimer’s disease is higher. The fraction of the population with dementia is smaller before the age of 65, and it increases after the age of 65. ![]() Alzheimer’s disease is characterized by atrophy, shedding, and degenerative alterations in brain cells, and its occurrence is linked to age. Most dementia cases are caused by Alzheimer’s disease (AD) and multiple infarct dementia (vascular dementia, multi-infarct dementia). 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. 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. Senile dementia, also known as dementia, is the mental deterioration which is associated with aging. ![]()
