Senior Care: Stress in Older Adults Affects Short-Term Memory
Source: ABC News Radio

(IOWA CITY, Iowa) -- When you’re stressed, it affects the way you think. However, in older adults, stress takes an even bigger toll on the mind by causing short-term memory loss. So why does this happen?

Researchers at the University of Iowa believe the answer is that under stress, the body starts over producing the hormone cortisol, which ordinarily keeps people on their toes when they feel threatened and helps us make quick decisions.

Too much stress over a period of time leads to too much cortisol and that can weaken the immune system, raise blood pressure and make people more susceptible to weight gain.

The other drawback is that a spike in cortisol levels also hobbles the brain’s prefrontal cortex in people 65 and older, which is responsible for short-term memory.

Although that seems to be another drawback of the aging process, there was a previous study that showed older adults with high self-esteem can keep their cortisol levels under control, which in turn, helps the elderly ward off certain health problems.
