A new study published in the Journal of Neurology suggests that regular exercise may be a key factor in preventing the onset of Alzheimer's disease. The researchers found that individuals who engaged in physical activity at least three times a week were significantly less likely to develop the disease compared to those who were sedentary. The study examined the relationship between exercise and Alzheimer's risk in a large sample of older adults over a 5-year period. The results showed that even moderate levels of exercise, such as walking or gardening, were associated with a lower risk of cognitive decline. These findings highlight the importance of incorporating regular physical activity into daily routines as a preventative measure against Alzheimer's disease. The study's authors recommend that individuals of all ages prioritize exercise as part of a healthy lifestyle to support brain health and cognitive function.
