Analyzing data from studies around the world involving hundreds of thousands of participants, Deborah Barnes, PhD, a mental health researcher at the San Francisco VA Medical Center, concluded that worldwide, the biggest modifiable risk factors for Alzheimer’s disease are, in descending order of magnitude, low education, smoking, physical inactivity, depression, mid-life hypertension, diabetes, and mid-life obesity. These risk factors are associated with 51 percent of Alzheimer’s cases worldwide and up to 54 percent of Alzheimer’s cases in the United States.
