Depression May Raise Risk of Alzheimer’s

People who have been depressed may be more likely to develop Alzheimer’s disease later, a study suggests. The study included 486 people, ages 60 to 90. They did not have any form of dementia when the study began. In the next 6 years, 33 developed Alzheimer’s disease. In the study group, 134 people had consulted a doctor because they felt depressed. They were 2.5 times as likely to develop Alzheimer’s as others in the study. Researchers said the cause is not clear. More research is needed. The study was published April 8 in the journal Neurology.
