Dementia risk increases with age; people over 65 are more likely to develop it, but younger individuals can also be affected. Other risk factors include:
- High blood pressure, high cholesterol, and diabetes.
- Head injuries and lack of regular exercise.
- Smoking, poor diet, and high alcohol consumption.
- Women are statistically more likely than men to develop dementia.
Healthy lifestyle changes, such as regular aerobic exercise, may help reduce risk and support brain health.
