Depression and Diabetes Both Increase Dementia Risk!
Previous research has shown that both type 2 diabetes and depression can independently increase an individual’s risk for dementia, but what happens when they co-occur? Danish researchers analyzed data collected from 2.4 million adults and found that while depression increases a person’s risk for dementia by 83% and the presence of type 2 diabetes results in a 20% greater risk, those with both type 2 diabetes and depression are 117% more likely to be diagnosed with dementia. This suggests that the presence of both conditions has a synergistic effect on dementia risk, not just an additive effect.
