Evaluation and Treatment of Depression May Reverse Memory and Cognitive Difficulties in Older Adults with Mild Cognitive Impairment”  reviews interesting research which found that older individuals with worse depression and mood symptoms are more likely to develop mild cognitive impairment (MCI), and to progress from MCI to dementia. The worse the symptoms of depression and mood disorder, the more likely the progression from MCI to dementia.

On the other hand, the researchers noted that improvements in depression and mood symptoms led to a greater likelihood of cognitive improvement. In fact, one third of the participants who had progressed to MCI had the benefit of reverting back to normal cognition with treatment of their depression and mood symptoms.
