Depression linked to dementia related brain changes

A study with 1,764 people (avg. age 77) was conducted, who were from the Rush Memory and Aging Project as well as the Religious Orders Study. These participants were constantly tested throughout the trial on various things such as, loneliness, depression, lack of appetite and their ability to think and memorize random bits of information for eight years. (Graham) 680 passed away during the study; autopsies were performed on the majority of the people to look for damage in the brain and signs of dementia. Problems with thinking and memory arose within 52% of the participants, which can indeed lead to Alzheimer's disease; it turns out that 18% of the people developed dementia. (Medical Center) Before the dementia started, a lot of people were more likely to have higher levels of depression symptoms but had a fast decrease in depression symptoms after dementia developed in their brain.
