"Identifying the Top 3 Changeable Risk Factors for Dementia"

A new study identifies a vulnerable brain network that is susceptible to both schizophrenia and Alzheimer's disease, with diabetes, air pollution, and alcohol consumption being the most impactful modifiable risk factors for dementia. The study, based on brain scans of 40,000 individuals, highlights the negative effects of these factors on brain health, while also noting the potential influence of genetics and external factors such as health, social, cultural, and educational influences on brain size and dementia risk. Additionally, another study suggests that modern lifestyles, including sedentary behavior and exposure to air pollution, may contribute to the increased risk of dementia.
