A new study shows that having depression may nearly double your risk of developing dementia later in life. The research will be published in Neurology®, the medical journal of the American Academy of Neurology.
"While it's unclear if depression causes dementia, there are a number of ways depression might impact the risk of dementia," said study author Jane Saczynski, PhD, with the University of Massachusetts Medical School in Worcester, MA.
"Inflammation of brain tissue that occurs when a person is depressed might contribute to dementia. Certain proteins found in the brain that increase with depression may also increase the risk of developing dementia. In addition, several lifestyle factors related to long-term depression, such as diet and the amount of exercise and social time a person engages in, could also affect whether they develop dementia."
