Regular exercise has been found to lower the risk of Parkinson’s disease in women, according to a long-term study, providing further evidence of its preventive benefits.
A recent study supports the idea that regular exercise can help prevent Parkinson’s disease. The research, conducted over a long period of time, focused on women and found that those who engaged in more physical activity had a lower risk of developing Parkinson’s compared to sedentary women. Previous studies had mainly observed this protective effect in men, so this study contributes to our understanding of exercise’s impact on women’s risk of Parkinson’s. One limitation in previous research was the possibility of reverse causation, where people with early Parkinson’s might reduce their exercise before their symptoms appear. To address this, the researchers analyzed data from a long-running study in France that followed the health of women over several decades. They found that women with Parkinson’s had reported less exercise on average even years before their diagnosis, indicating a potential link between exercise and reduced risk. Although the study doesn’t definitively establish a cause-and-effect relationship, it strengthens the case against reverse causation and suggests that physical activity may contribute to preventing or delaying Parkinson’s disease.
