Chronic Strain

Stress is the bane of modern urban life and it is imperative to reduce it. This has resulted in exhaustive research in the area. Now scientists from Semmelweis University of Budapest, MedUni Vienna, Yale University, and Karolinska Institute have uncovered a process occurring in the brain that can cause delay in response to stress and can result in long-term effects of stress and chronic strain. They found that a lapse of 10 minutes post the “danger,” the brain area that responds to stress and accordingly acts is activated through the cerebral fluid. Such a discovery might lead to new approaches to fathoming the neuronal methods playing out in cases of chronic strain, post-traumatic stress disorder, and burnout.

As per one of the scientists, earlier they knew about just two stress mechanisms in the brain. A clutch of neurons situated in the hypothalamus triggers both mechanisms. While one of the methods creates a hormonal pathway that causes hormones to be released from the adrenal glands into the bloodstream, the other process is the nerve pathway. The latter is way swifter in establishing a neural connect directly to the prefrontal cortex.

The latest discovery by the group of scientists from the universities mentioned at the start showed that the same neurons can also lead to a third type of stress response. This does not happen immediately. However, even though occurring later, the effect lingers for a while. The whole new mechanism that has been described progresses through the cerebrospinal fluid.
