Making changes to your lifestyle can reduce the risk of stroke, dementia, and late-life depression simultaneously, reveals a recent study. Researchers have identified 17 common risk factors for these brain-related conditions, emphasizing that addressing even one factor can have a positive impact on others. For instance, engaging in activities like biking to boost physical activity can help manage high cholesterol and blood pressure, which are shared risk factors.
The study underscores the potential for prevention of these conditions, especially considering the projected increase in dementia cases by 2050. Previous research indicates that addressing modifiable risk factors could prevent a significant percentage of strokes, dementia, and late-life depression cases.
Aleksandra Pikula, a vascular neurologist and study co-author, highlights the importance of understanding shared risk factors among these conditions. The study, published in the Journal of Neurology, Neurosurgery & Psychiatry, analyzed data from multiple studies to compile a list of 17 modifiable risk factors.
Four factors were identified as beneficial, including cognitive activities, physical activity, a sense of purpose, and moderate alcohol consumption. Conversely, eleven factors were associated with increased risk, such as high blood pressure, smoking, and poor sleep quality. Additionally, diet and social engagement were found to have both protective and detrimental effects on brain health.
High blood pressure emerged as the most significant risk factor among the three conditions. Addressing this silent killer through lifestyle changes or medication can have a substantial impact on reducing the incidence of these conditions. The study emphasizes the importance of starting risk factor reduction in mid-life for optimal outcomes.
Although the study focused on associations rather than causation, it provides valuable insights for developing targeted interventions at a population level. Implementing lifestyle changes, such as increasing physical activity and social engagement, can significantly reduce the risk of developing these brain-related conditions.
Experts suggest that promoting physical activity and healthier lifestyles through policy changes is crucial for preventing chronic diseases like dementia. By implementing interventions at a population level, such as tobacco control measures and creating supportive community environments, lasting changes can be achieved to address these conditions effectively.
