Research published in the Alzheimer’s & Dementia: the Journal of the Alzheimer’s Association may indicate a significant step forwards in developing a blood test which could be able to predict the risk of Alzheimer’s Disease onset with 87% accuracy.
Research on more than 1,000 people, at various stages in the transition from mild cognitive impairment to Alzheimer’s Disease, has identified a set of ten proteins in the blood.
This development raises the possibility of a test capable of predicting, reasonably accurately, which patients with mild cognitive impairment are likely to develop Alzheimer’s Disease in the following year. Such a test to predict the development of Alzheimer’s Disease – and / or other forms of dementia – could reduce the high number of failures in drug trials, thereby facilitating medical research and ultimately the development of new treatments, as has been discussed earlier.
