- Forty percent of dementia cases can be prevented or delayed by adopting lifestyle changes
- Nine dementia risk factors were reported by experts in 2017
- Additionally, three dementia risk factors – alcohol consumption, air pollution and head injury were added recently
Dementia could be prevented by modifying twelve risk factors over a lifetime. The risk factors could prevent 40% of dementia cases. The report was presented as Alzheimer's Association International Conference (AAIC 2020)
What is Dementia?
Dementia is not a single disease, it is a collection of medical conditions which results in deterioration in memory, behavior, thinking, social abilities and the ability to perform everyday activities.
Dementia mainly affects older people and includes Alzheimer's Disease.
An increase in dementia is expected especially in low- and middle- income countries. Women are also at a higher risk of developing dementia compared to men.
In developed countries, the rate of dementia has reduced due to lifestyle changes suggesting the possibility of preventing dementia.
What are the Risk Factors of Dementia
Dementia experts in 2017 identified nine risk factors:
- Less education early in life
- Hearing loss in mid-life
- Social isolation
- Physical inactivity

- Head injury in mid-life
- Air pollution in later life
What are the Interventions Recommended by AAIC Commission?

- Restrict the amount of alcohol consumption to 21 units per week. (1 unit is equal to 10 ml of alcohol)
- Quit smoking and encourage others to also quit
- Primary and secondary education must be made compulsory for all children

The commission conducted a thorough study in order to reach their conclusions.
