Stress Weakens Memory Ability


stress weakens memoryA study revealed that prolonged stress not only leads to mental fatigue, but also affect the ability of memory.

The study, conducted by a team of researchers from the State University of New York at Buffalo on rats, showed that repeated stress causes disturbances in the brain called the prefrontal cortex.

Prefrontal cortex is known as the “CEO of the brain”, responsible for abstract thinking and cognitive analysis, as well as how to act properly in a situation, accoriding to the Huftington Post.

MedPage Today also reported that memory problems can be sourced from the glutamate signal interference, in which the signal is very important in supporting the function of prefrontal cortex.

Based on the study published in the ‘Neuron journal’, glutamate receptor lose signal when the rats had high levels of stress. This in turn triggers a negative effect on the processing of information stored in the brain.

In 2008, a study published in the ‘Journal of Neuroscience’ also shows the relationship between stress and memory. The study, which also involved rats, suggest that brief periods of stress is able to disrupt brain cell communication in areas associated with memory and learning.

The release of the cortisol stress hormone which is high makes a number of rats having trouble remembering how to go through the maze. Stress hormones are known to have powerful effects that can damage the body.

Not only does it has the potential to disrupt the memories in the future, the release of the cortisol hormone can also lead to changes in metabolic processes. Which in turn lead to abnormal blood sugar levels, accelerate osteoporosis triggers bone shrinkage, as well as interfere with the immune system. That is why people who are stressed are susceptible to diseases.

Seeing the bad effects, yous should not underestimate the situation if stress hits you. There are actually many things you can do to overcome stress. Previously, it was known that you can beat stress with right choice of foods.
