Brain highlights the study "Midlife Psychological Stress and Risk of Dementia" by Lena Johansson and colleagues that details the relationship between psychological stress in midlife and the development of dementia in late life. A representative sample of females aged 38-60 years were examined in 1968-69, and re-examined in 1974-75, 1980-81, 1992-93 and 2000-03. During the 35-year follow-up, 161 females had developed some type of dementia. The risk of dementia was about 65% greater for women who reported stress in midlife as compared to those who did not.
