According to the research conducted by the scientists from the University of Magdeburg (Germany), the release of dopamine hormone in the body increases long-term memory performance in terms of storing information.
The tests involved senior people aged 65 to 75 years. Some of them received pills containing dopamine, while the others were given pacifiers. The indicators of the second group did not change, whereas the first group demonstrated about 20-30% better long-term memory in comparison with the average figures.
Thus, the “hormone of happiness” is not only useful for the psyche, but for the body as well: the improvement of memory and cognitive function of the brain is proved to be able to protect the person from the development of degenerative diseases (Parkinson’s disease, Alzheimer’s disease and others).
