Stress and the brain

Cortisol, the stress hormone is linked to shrinkage or atrophy of the hippocampus, the area of the brain that is responsible for memory.

"We found those with high cortisol levels and high amyloid, declined in terms of their memory performance at a much faster rate than those that had high amyloid, but low cortisol, so the cortisol levels in their blood was contributing to a faster rate of memory loss."


Professor Simon Laws, Edith Cowan University

"There is a growing body of evidence that increased cortisol may be deleterious for the late-life cognitive performance, and may be associated with an increased risk for cognitive decline and dementia, in particular dementia due to AD. In patients with AD, the increased cortisol at preclinical and early clinical stages is associated with a poorer prognosis and a more rapid cognitive decline."
