With evidence showing that lifestyle factors play a key role in the development of dementia, modifying certain habits can help prevent the disease. Quitting smoking, including an exercise schedule, controlling on bad food habits all of these help in reducing risk of dementia. Diabetics have 50% increased risk of dementia. Therefore modifying our behaviors in the beginning can go a long way to keep us healthy in later life. People with signs of dementia must also ensure that they keep their brain active to avoid further progression of the disease. There is increasing evidence suggesting that people in their old age with healthier brains are at a lower chance of developing dementia. They can also lead longer and happier lives.
