Dementia is a complex disease with multiple risk factors. There are certain non-modifiable risk factors of dementia such as age, gender and genetic predisposition. However there are potentially modifiable risk factors, which may reduce your risk of developing dementia and delaying the onset of symptoms. The evidence shows that people who attain higher level of education are less likely to develop dementia. Hence, it is important to remain mentally active and socially engaged even as a person grows older. Other essential measures include physical exercise with healthy lifestyle, avoid obesity, untreated depression and social isolation. Remember to perform regular health checks to ensure your blood pressure, glucose level and cholesterol levels are in good control.
