According to a new study published in the online issue of official medical journal of the American Academy of Neurology, Neurology, depression in older adults could have a ling to memory-related problems. The study also suggests that in older people with larger symptoms of depression, the brain may have structural differences as compared to the brains in people who are not showing symptoms for depression.

As depression symptoms can be effectively treated, it may become possible that the early treatment of these systems could bring a reduction in memory and thinking issues seen in older adults with depression. The better understanding between memory issues and depression could help better treat nearly 25% of the total number of older adults showing depression symptoms.

The study researched 1,111 people, all with an average age of 71 years and all stroke-free. All underwent brain scans, an assessment of thinking and memory skills, and a psychological exam at the beginning of study. The thinking and memory skills of all the people studied were analyzed after an average of five years again. During the beginning of the research, nearly 22% of the participants showed symptoms of depression. The rate of depression was estimated based on a clinical depression risk test.

It was found in the study that greater depression symptoms were related to worse state of episodic memory in the subjects. Also, subjects that displayed greater depression symptoms had structural difference in brain such as 55% more possibility of forming small vascular lesions in the brain as well as smaller volume of linkage was found between gravity of depression symptoms and change in thinking skills over the period of research in the subjects.
