Content: It was found that the rats exposed to chronic psychosocial stress could not learn to adapt to new situations and environments, and had impaired memory on the RAWM. Chronic stress affects a person's cognitive functioning differently for normal subjects versus subjects with mild cognitive impairment. Chronic stress and elevated cortisol (a biomarker for stress) has been known to lead to dementia in elderly people. A longitudinal study was performed which included 61 cognitively normal people and 41 people who suffered from mild cognitive impairment. The participants were between 65 and 97 years old. 52 of the participants were followed for three years and repeatedly received stress and cognitive test assessments. Any patient that suffered from signs or conditions that would affect their cortisol level or cognitive functioning was exempt from participating. In general, higher event based stress was associated with more rapid cognitive impairment. However, participants with greater cortisol levels showed signs of slower decline. Neither of these effects held for the non-cognitively-impaired group.
