Decline in abstract reasoning correlates with later depression. Studies are ongoing:
- to examine the potential mechanisms at work in the correlation... such as unmeasured disease processes, genetic susceptibility, and declines in daily functioning.
- to try to break the correlation with interventions... such as training, treatment, and social support.

Even prior to receiving research results, it may be wise to live as though taking care of one's health, simplifying the daily routine, enjoying positive social interactions, and receiving acceptance and affirmation from family and caregivers despite age-related cognitive decline... may help stave off depression symptoms in older adults experiencing cognitive decline.
