Scientists do not stop to explore the coffee and its effect on the human body. Opinions appear different - both good and bad. Some experts try to prove a positive effect of the drink on our bodies, some - bad. Not long ago, researchers decided to find out - how refreshing drink acts on the human brain.

Previously, scientists have only talked about the positive impact of coffee on the human brain. However, a recent study showed the other side - is that dependence on the drink can vary dramatically, though it occurs over the years. Therefore, the best recommendation of physicians - to change the dose of coffee for a living. This applies to the elderly. It is the brain of the people of above 60, coffee has a strange effect - impairs brain activity.

Italian scientists are interested in the question of the effects on the cognitive functions of the human brain may cause excessive consumption of coffee. The research, which lasted for three years, have shown that frequent use of favorite for many people drink can impair memory and even lead to some dangerous diseases.

In the experiment, attended by more than one and a half thousand volunteers, observations were conducted for a group of patients, which included men and women aged 65 to 85 years. It turned out that those who have for years been drinking on the day of one or two cups of coffee were less prone to mental illness than completely sober or drinking coffee only occasionally.

According to their findings, people who adhere to the habits of moderate coffee consumption (1-2 cups a day), the probability of the development of small cognitive biases was generally lower as compared to those who did not drink coffee or do it rarely. More frequent consumption of coffee does not give decrease such risks.

But that's changing the usual amount of coffee proved dangerous. So, those people who in old age began to drink more cups than accustomed for many years, the risk of mild cognitive impairment were approximately 1.5 times higher than in those who remained faithful to the habits.

Also cognitively healthy people who have changed over the study period the habit of coffee consumption upward, there were twice as likely to develop cognitive problems than those who reduced the consumption of the beverage.

What is the reason, scientists can not yet say for sure.
