Resumen de A test to see if you will get Alzheimer's
There is now a test to predict Alzheimer's disease two or three years before symptoms occur. The assessment, the first to give such early warning, identifies 10 molecules in the blood associated with the disease before symptoms start. The hope is that it might be able to predict Alzheimer's disease decades in advance and help the development of preventative therapies. Howard Federoff at Georgetown University in Washington DC and his colleagues studied 525 people aged 70 and over for five years. The group showed no signs of mental impairment at the start of the study. Each year, the team performed a detailed cognitive examination and took blood samples from the participants. During this time, 28 people developed Alzheimer's or mild cognitive impairment, thought to be the earliest noticeable sign of several types of dementia, including Alzheimer's disease.
