A new and simple blood test may able to accurately predict Alzheimers disease years before its symptoms are noticeable. The test could detect with 90 percent accuracy whether or not a healthy individual will develop Alzheimer’s or amnestic mild cognitive impairment could come on the market within the next three years, researchers say. If future and larger studies mirror the results, the test could fill a major gap in treatments to combat brain degeneration. It could allow for early intervention with drug therapies and for patients to complete early estate planning and documentation and if they desire, to make arrangements for long term care. Despite years of research and some medications, there is not yet a good treatment for Alzheimers, which affects an estimated 35 million people.
