Researchers are working to find out ways by which Alzheimer's disease can be diagnosed early, i.e. before it occurs and even before it shows any symptoms. Experts from the National Institute on Aging and the Alzheimer's Association have proposed some ways on the same that include three major stages of the disease: the pre-clinical Alzheimer's, the mild cognitive impairment, and the Alzheimer's dementia.
This research is important because Alzheimer’s disease is a very dreadful degenerative brain disease and it neither has any cure nor any proper rules for diagnosis, until its last stage. Therefore, experts are focusing upon it and are also preparing drugs for its treatment.
According to a survey conducted by Alzheimer's Association, it was revealed that more than 5.3 million Americans are suffering from this terrible disease, and out of them, most people are above the age of 65 years.
Creighton Phelps, PhD, Director of the Alzheimer's Disease Centers Program in the Division of Neuroscience at the National Institute on Aging in Bethesda, Md, said that they want to be prepared with such cases, and are thus discovering ways by conducting constant clinical trials.
He further added, “If the results should be positive, the idea is that they will work better in someone whose brain is relatively intact so the earlier we can diagnose someone as being on track for Alzheimer's disease, the better these agents may work”.
