HealthDay News) -- For people with mild cognitive impairment, depression is associated with high risk for development of Alzheimer's disease, but the association can be mitigated with the Alzheimer's disease drug donepezil, according to a study in the June 16 issue of Neurology.

In the current research, the Beck Depression Inventory was used to assess depressive symptoms at study baseline and the cohort was divided into depressed and nondepressed subgroups.

The researchers found that higher Beck Depression Inventory scores were associated with development of Alzheimer's disease.
