New biomarkers offer hope for early detection and prevention of Alzheimer's

The failure to diagnose Alzheimer's disease, the most common form of dementia in the elderly, at an early stage of molecular pathology is considered a major reason why treatments fail in clinical trials. Previous research to molecularly diagnose Alzheimer's disease yielded "A/T/N" central biomarkers based on the measurements of proteins, β-amyloid ("A") and tau ("T"), and "N" encompassing neurodegeneration. A/T/N can be measured in brain tissue, by in vivo brain imaging techniques, and by analysis of cerebrospinal fluid and plasma.

Leptin variations may influence brain health and dementia development

New research is more closely linking obesity to dementia. Higher levels of leptin, a hormone that helps maintain normal body weight, is associated with better signal-transmitting brain white matter in middle-aged adults, according to a study by The University of Texas Health Science Center at San Antonio (UT Health San Antonio).
