Genetics

Genetics is the study of genes and heredity. Heredity is the passing of genetic information and traits (such as eye color and an increased chance of getting a certain disease) from parents to offspring.

Blood metabolites reveal lifestyle links to brain health before dementia

Blood metabolome profiling in dementia-free middle-aged adults linked 14 metabolites to cognition and 22 metabolites to MRI markers of brain health. Lifestyle, clinical factors, medication use and gut microbiota appeared to shape many of these metabolites, with ergothioneine emerging as a notable cognition-linked signal.
