Stress is harmful for the brain in older people - the scientists

Stress affects all organs and systems. The brain is no exception. Constant anxiety, processing and conflicts affect the functioning of neural connections. The signal simply does not pass, that affects the person's ability to remember and thinking.

Data were installed in the experiments with laboratory mice. Overstrain of the nervous system and the constant stress activates a genetic mutation. Especially dangerous in old age, when any pathology can lead to irreversible changes.

Thus, mice exposed to constant stress, had fewer neural connections than rodents from the control group. Animals after stress had no control of their own actions.

Scientists have proved that stress hormones disrupt the normal functioning of the nervous system, destroy educated connections between neurons. If at a young age such processes can take place without a trace, older years any anxiety exacerbates age-related cognitive impairment.
