According to Alzheimer's Association, 44 million people worldwide are living with dementia and by 2050 the number is expected to reach 115 million. 

Here is our effort in spreading the awareness about Alzheimer's disease and other forms of dementia. 

Five lesser known things about Alzheimer's: 

1. Hypertension may help save your brain

Yes, you heard that. If you're over 90, hypertension can save the life of the brain cells. According to a new study from the University of California, hypertension may protect against dementia in people over age 90. 

However the study also not promotes hypertension in the elderly, given that high blood pressure is related to other bad outcomes.

2. Its never too late 

Implementing lifestyle factors, which includes nutritional guidance, physical exercise, management of heart health risk factors, cognitive training and social activities, even in midlife can hedge against Alzheimer's disease later on. 


3. Playing games increases size of the brain

Middle-aged people who were avid game-players tend to have bigger brains than people who did not play games, reported a new study. The volume of the brain part among game-players was larger in areas that tend to be damaged by Alzheimer's disease. 


4. Exercise is beneficial for mind too

Exercise may positively influence how cognitive impairment and dementia develop, two sets of data from the Mayo Clinic Study of Aging suggest. The data further showed that patients who exercised - either lightly or vigorously - were less likely to be diagnosed with cognitive impairment. 

5. A simple smell test would detect Alzheimer's 

Researchers are working on a test of smell that would help doctors predict risk of developing Alzheimer's disease

Researchers, in a study, reported that people who were unable to identify certain odors were more likely to experience cognitive impairment. Experts believe that brain cells crucial to person's sense of smell are killed in the early stages of dementia.
