The study found that middle-aged adults with high levels of cortisol had lower brain volume and cognitive function than those with lower cortisol hormone, indicating that stress was the cause.
The hormone cortisol is involved in a number of normal processes of the body, including metabolism, immunity and memory formation. But extra cortisol is also released when we are stressed, thereby increasing the body's process.
Although the study did not look deeper to find out if there were people with dementia, this effect could be a factor of later cognitive decline, said one of the authors of the study, Sudha Seshadri, professor of neurology at UT San Antonio Health. "We have already shown that changes of this magnitude predict the level of mental dementia, or even vascular brain injury, two or three decades later," said Seshadri.
The study involved more than 2,200 adults who participated in the Framingham heart study, whose average age was 48 years. Everyone underwent a psychological examination at the beginning of the study, which tested memory and thinking skills, and was examined again about eight years later.
They also gave blood samples, which researchers used to measure cortisol levels, and the majority of them had an MRI to measure brain volume.
