HealthDay (8/12, Preidt) reports researchers found “a significant link between worsening depression symptoms and mental decline over two to seven years, and both of these trends seemed to be linked to a buildup of amyloid protein in brain tissue.” The study’s lead author, Dr. Jennifer Gatchel of Massachusetts General Hospital, said the study’s results suggest that “depression symptoms themselves may be among the early changes in the preclinical stages of dementia syndromes.” The findings were published in JAMA Network Open.

Health IT Analytics (8/12, Kent) reports the researchers “found that mild or moderate depression together with brain amyloid, a biological marker of Alzheimer’s disease, could result in changes in thinking and memory over time.”
