Index – Science – Aging, Memory and Alzheimer’s: Caffeine!

Caffeine is the world’s most consumed psychoactive substance, with 80 percent of the world’s population using it in the form of coffee, tea or soft drinks. Your PR hasn’t always been good, but the positive news is getting stronger lately – that affects everything in the right direction Alkaloid coffee/tea/cola and caffeine. According to the current view of science, not eating a lot is especially good for health.

The molecular pathways of regular consumption are still not fully understood, but more and more experiments are being conducted on small mammals to explore the effects of caffeine on the body. The temper natureIn a recent study published in We can read about the experience of David Bloom, a professor at the University of Lille, and Anne-Lawrence Butelier, a researcher at the University of Strasbourg.

Glaze list of precious rodents

French lucky rats were soaked in caffeinated water for two weeks and then the hippocampus of the rodents were examined for any change after ingestion of the stimulant. The research team discovered that the area of ​​the brain responsible for memory was more active than the hippocampus of decaffeinated mice. Studies of their brains have shown that caffeine induces neuron-specific epigenetic changes in certain genes, increases the activity of transcription factors (DNA-related proteins that can suppress or help express genes) and even has a positive effect on brain metabolism. So caffeine, in addition to increasing our alertness, also has lasting changes in the brain can cause.

Both bees and rats contained caffeine

This time, not only did the mice benefit from the caffeine, but the bees finally got a good turn from the scientists: after ingesting the caffeine, they were examined and found that they were able to remember the smell of the previously acquired flowers. On the other hand, caffeinated mice performed better on memory tests. These results are consistent with the observation that caffeine improves the hippocampus’ ability to regulate neuronal excitability.

Overall, the researchers concluded that regular caffeine intake improves information encoding, normalizes synaptic plasticity, and may positively affect cognitive decline, such as in Alzheimer’s disease or other neuropsychiatric conditions. So just drink it peacefully over two or three cups of coffee a day until We can still do it.
