Salivary cortisol patterns predict cognitive decline in older adults

An irregular pattern and consistently higher levels of a stress hormone called cortisol found in the saliva were associated with cognitive decline later in life - Blacks specifically had lower overall cortisol levels and less change in their levels during the day than whites - according to newly published research.

Largest neuroimaging study of bulimia nervosa finds structural brain differences linked to diagnosis and binge-eating severity

Researchers at the Icahn School of Medicine at Mount Sinai found that individuals with bulimia nervosa have structural differences in brain regions involved in reward and motivation, as well as social and sensory processing, and that more frequent binge eating is associated with more widespread differences in brain structure, according to research published today in JAMA Psychiatry.
