American scientists from the University of Rochester have found that small amounts of alcohol reduces the risk of Alzheimer’s disease. Article researchers published in the journal Scientific Reports, a brief account of the scientific work described in the press release on the website MedicalXpress.
Experts have established that alcohol has a beneficial effect on limfaticheskoi system, which purifies the Central nervous system of mammalian waste products. Limfatica system was opened in 2012 in the course of the experiment on mice. It is based on the pumping of CSF (cerebrospinal fluid) in brain tissue and its subsequent removal together with a number of proteins and other compounds that can participate in the development of dementia and other pathological conditions.
It turned out that the consumption of large amounts of alcohol over a long period of time negatively affect the function of limfaticheskoi system, which is reflected in the growing number of inflammation markers in astrocytes — cells that are key regulators of injection of the cerebrospinal fluid. However, low doses of alcohol (0.5 grams per kilogram of body weight per day) enhanced the effectiveness of the system in rodents compared to mice from the control group.
According to scientists, the data suggest that low to moderate alcohol consumption reduces the risk of developing dementia, whereas excessive addiction to alcohol negatively affects cognitive abilities.
