Depression and Diabetes Can Increase Risk of Dementia
A new study has indicated that the combination of having diabetes and depression can significantly increase the risk of developing dementia. The study, lead by Dr. Dimitry Davydow, an associate professor of psychiatry and behavioral sciences at the University of Washington School of Medicine in Seattle, was published to the April 15 online edition of JAMA Psychiatry.
The study looked at roughly 2.4 million people in Denmark that are age 50 or older that have had depression, Type 2 diabetes or both conditions at the same time. The findings indicated that the risk of dementia increased by 15 percent if the patient had diabetes alone. If the patient had depression, the risk of dementia increased by 83 percent. If the patient had both conditions, then the risk of dementia increased by 107 percent.
The association between diabetes, depression and dementia was even stronger for people that were under the age of 65. For this group, roughly 25 percent of the cases of dementia were due to depression and diabetes. The study indicates that there is a link between depression, diabetes and dementia but was unable to establish a cause and effect link between the conditions.
The researchers attribute the findings to the fact that both depression and diabetes create threats to vascular health. Therefore, lifestyle choices can be extremely helpful in preventing dementia because they can make a huge difference in the quality of life for diabetes and depression patients. The researchers recommend that all groups increase physical activity levels.
