When it comes to a diagnosis of Alzheimer’s disease, what you don’t know may not kill you, but knowing the truth as soon as possible appears to be the better approach — one that may improve the emotional well-being of both patients and their caregivers, suggests new research from Washington University in St. Louis.

Medical advances have made it possible to diagnose Alzheimer’s at very early stages, but a 2004 review of research found about half of all physicians were still reluctant to inform patients of an Alzheimer’s diagnosis. While many physicians fear a dementia diagnosis would only further upset an already troubled patient, this follow-up study found quite the opposite.

“We undertook this study because we wanted there to be some data out there that addressed this question and that we could show to physicians and say, ‘Most of the people don’t get depressed, upset and suicidal. So, this fear that you have about telling them and disturbing them is probably not legitimate for most people,'” says Brian Carpenter, Ph.D., associate professor of psychology in Arts & Sciences at Washington University.

The study, published in the current Journal of the American Geriatrics Society, is co-authored by Carpenter and colleagues in the Division of Biostatistics, the Department of Neurology and the Alzheimer’s Disease Research Center at the University’s School of Medicine. [continue reading…]

Depressed heart attack patients have a higher risk for sudden death in the months following a heart attack. Now a team led by researchers from Washington University School of Medicine in St. Louis has found that the risk continues for many years.”There’s a two- to four-fold increase in a person’s risk of dying following a heart attack if they also happen to be depressed,” says Robert. M. Carney, Ph.D., lead author of the new study and professor of psychiatry at Washington University. “Previously we thought the impact of depression was strongest for the first three to six months following a heart attack and then gradually dropped off within a couple of years. Instead, we found that the effect lasts for at least five years.”

Carney, with colleagues from Duke University Medical Center, Harvard University, Yale University, the National Heart, Lung and Blood Institute (NIH) and the Mayo Clinic, followed more than 750 heart attack patients for five years. The findings will appear in an upcoming issue of the Journal of Affective Disorders and are currently available online. [continue reading…]
