Memory loss because of biological clock disturbance

Research by US scientists shows that people who travel long distances through many meridians often spend a month recovering some memory.

Associate Professor Lance Kriegsfeld of the University of California is the director of the study. He said ' jet-lag ' is a fatigue phenomenon due to the body's internal clock disturbance after a long flight across time zones. His research and colleagues on the long-term effects of changes in life rhythm to the brain suggest that impairment of brain function can also occur in people who often work night shifts, or time Schedule is not fixed . Therefore, people who are constantly disrupting their daily circadian rhythms - including flight attendants, hospital staff, or shift workers - are all vulnerable to long-term behavior. and cognitive function .

To conduct research, scientists have been working on hamsters. Hamster rats were selected as subjects of study because they have an accurate daily circadian rhythm and are controlled by a 24-hour circadian clock, similar to the human biological clock.

The object of the study is a group of hamsters

The mouse girls had to experience a 6-time difference - the equivalent of a flight from Paris to New York. This change of time takes place twice a week and lasts for a month. The results showed that the hamster group ' research subjects ' were more tired and absent than the ' control ' hamster group. Surprisingly, the ' study subjects ' group of mice that took months to live in normal conditions could ' restore memory '.

It took a whole month for him to be distracted and recover his memory

Explaining the phenomenon, the researchers said they have traced changes in neuronal neutron decline in the ' Hippocampus hill ' - the brain region plays an important role in retaining and recalling memory. emotion and awareness. Accordingly, compared to the stable hamster group, the group of mice often suffered from time zone difference only formed half of the new neuron neutron in the ' Hai code hill ' within a month, after having to often undergo 'jet-lag'.

Not only that, other studies have shown that people who often have to fly through many time zones also exhibit dementia or reduced learning ability, even appear at the temporal lobe atrophy. Scientists claim that the time zone difference has reduced the formation and development of neurons in the ' Hippocampus hill ' and could lead to the risk of reducing function in this brain region.

This new finding may explain in part why workers often have to work as shifts and those who travel long distances . often react slowly and are more susceptible to diseases such as diabetes and heart disease. , high blood pressure, cancer and impaired reproductive function.

To minimize these harmful effects, Associate Professor Kriegsfeld recommends that people who regularly change biological clocks should spend a day off for every hour of difference . Night shift workers should sleep in a quiet dark room so that the body can adapt to changing working time in life ' taking night and day and night .'
