Emerging noninvasive biomarkers for early detection of Alzheimer's disease.
Alzheimer's disease (AD) diagnosis still depends on the triad of clinical, imaging and neuropsychological testing. The development of accurate, easy to use and inexpensive biological markers for AD is a long-standing aspiration for researchers and the medical community. Here we describe some of the recent advances in the field of biomarkers, both in cerebrospinal fluid (CSF) and in peripheral blood.
