Harvard researchers have identified over a dozen risk factors for dementia and other brain disorders that are preventable and modifiable. The study, which analyzed 37 studies on dementia, stroke, and late-life depression, found that at least two of the disorders could be caused by 17 shared risk factors.
The most common and modifiable risk factors included high blood pressure, diet, and physical activity. However, “overlooked” factors such as fulfillment in life, hearing quality, and pain sensitivity were also linked to brain disorders.
Researchers found that having a purpose in life can protect against changes in the brain that lead to dementia, while a high quality of life reduces the risk of depression. Chronic pain has been shown to lead to depression, and poor hearing can cause cognitive strain and prevent social interactions, which add stress to the brain.
The study’s findings are hopeful, as they suggest that preventive efforts could lead to a reduction in the incidence of dementia, stroke, and depression. However, the researchers emphasized that their findings are based on associations rather than direct causes.
To reduce their risk of developing these age-related brain diseases, individuals can take steps such as managing high blood pressure, maintaining a healthy diet, staying physically active, finding fulfillment in life, and addressing chronic pain. By making these modifiable changes, individuals may be able to lower their risks for dementia, stroke, and depression.
The study’s authors called for more research on modifiable brain health factors and stopping diseases like dementia before they occur. As the researchers stated, “Our study identified 17 modifiable risk factors shared between stroke, dementia, and/or late-life depression, emphasizing that there are many different steps individuals can take to lower their risks for these age-related brain diseases.”
