Epidemiology

We should have guessed it earlier. Alzheimer’s disease is the most frequent type of dementia in the elderly and it affect almost half of all the patients suffering from dementia. As Mum grew older, her risk for getting this disease multiplies. Amongst all the people who have an age of 65 years, 2-3% of them show some signs and symptoms of the disease, while 25-50% of all those aged 85 have symptoms and a larger number will have the disease without its usual symptoms. With every 5 years after 65 years old, the probability of contacting the disease doubles. I simply could not imagine how many people in the world suffered the same disease as Mum did. It is such a unexpectedly large number of the people suffering and slowing dying before the eyes of everyone due to Alzheimer’s disease.
