Having depression is known to increase your risk for developing Alzheimer’s disease. Now a new, preliminary study released today, February 24, 2021, reports that if people do develop Alzheimer’s disease, those with depression may start experiencing dementia symptoms about two years earlier than those who do not have depression. People with anxiety who develop Alzheimer’s may start experiencing dementia symptoms about three years earlier than those who do not have anxiety, according to the study that will be presented at the American Academy of Neurology’s 73rd Annual Meeting being held virtually April 17 to 22, 2021.
