Scientists have found that a state of constant stress can disrupt brain function, causing massive destruction of neurons, accompanied by a loss of memory. In the future, these processes can become a cause of Parkinson's and Alzheimer's diseases.
Most scientists interested in the hippocampus, which is involved in the processes related to the systematization and preservation of long-term memories. This brain memory center is different in that its nerve cells die much more frequently and are more prone to degeneration than other neurons.
Scientists have suggested that this may be due to the fact that the neurons of the hippocampus are more vulnerable to various inflammatory processes in the brain, developing under the influence of stress. This hypothesis is decided to check on laboratory rats.
It was found that under the influence of nervous tension rodent hippocampus inflamed, causing die entire neural structures, carrying with it the accumulated memories. And the worst part is that the processes that are running stress, do not stop immediately after the elimination of the source of negative emotions. Even a month after the end of the experiments, the level of molecules in the hippocampus, associated with inflammation, continued to be extremely high. The researchers believe that the consequences can be dire.
It turns out that the cessation of chronic stress by itself does not save the hippocampus from the beginning damage. In the future, it can threaten the development of dementia and emotional disorders.
