Stress The Short Term Reduce Remember

Stress the short term that lasts only a few hours can damage the brain-cell communication in some areas related to the ability to learn and remember the power, said the researchers from Unviersity of California.

Have known that the stress of the last several weeks or months can damage cells in the area of communication and memory in the brain's ability to learn, but the study gave the first evidence that short-term stress has the same impact. Study in the Journal of broadcast Neurosicence.

"Stress continues to occur in our lives and can not be dodged," said Dr. Tallie Z. Baram, the leader of the study. "Our findings can play an important role in the development of drugs at this time that might prevent the impact that this is not desirable and offers understanding of why some people forget or have difficulties to maintain the information during the full pressure of the situation."

In their study, Baram and colleagues identified a new process of how stress is causing the impact. They found that not involve hormones, known as the broad causes of stress, cortisol, which flows throughout the body, acute stress the fact that certain molecules called corticotropin releasing hormones (CRH) - which disrupt the process of how the brain collects and stores memories.

The researchers found that these molecules inhibit the interaction with the CRH molecules reseptor eliminate stress on the damaged area involved with learning and memory.

Baram also said that there are groups that show the ability to inhibit reseptor CRH, and studies that can play a role in the establishment of therapy based on the collection in order to handle the loss of memory and learning ability related to stress.
