DNA, RNA blood test may help detect Alzheimer’s earlier: study

A blood test that looks at both DNA and RNA information may help identify Alzheimer’s disease patients more accurately, according to a study led by researchers from Seoul National University Bundang Hospital and Indiana University. The researchers sought to develop a more practical way to screen people at high risk of Alzheimer’s disease, the most common cause of dementia. Current precision tests, such as positron emission tomography scans and cerebrospinal fluid tests, can be costly or invasive
