Alzheimer's is not an essential part of aging — it's a disease. As of 2016, more than 40 million people are afflicted by Alzheimer's, and by 2050, every second person over 80 years old is expected to be afflicted. In this video, Alzheimer's researcher, Samuel Cohen talks about how although there is currently relatively little that can be done to prevent, cure or slow the disease down, with more research and study on normal mental function in old age, a cure is possible. Significantly less money and time has been spent on Alzheimer's research as compared to other diseases. Research in cancer and AIDS has benefited from awareness initiatives by patients and relatives, and it's time to push for the same in Alzheimer's.
