“Call of Duty” puts you in risk of Alzheimer’s disease

According to the scientists of Montreal University, those teens who spend a great deal of their time playing “Call of Duty” and “Assassin’s Creed” may be at increased risk of Alzheimer’s disease and some other mental disorders in mature age.

According to the scientists of Montreal University, those teens who spend a great deal of their time playing “Call of Duty” and “Assassin’s Creed” may be at increased risk of Alzheimer’s disease and some other mental disorders in mature age.

When boy plays those games, he navigates the screen using one of the most important parts of brain – caudate nucleus. That causes loss of grey matter in the hippocampus. Due to previous studies, researchers have made, the volume in the hippocampus was greatly reduced. Hippocampus controls memory, learning process and emotions that person feels. It is also associated with such neurological and psychological disorders like dementia and depression.

The Canadian team thinks that if those eager players have less grey matter, they are more likely to have mental illnesses. The study was published in Proceedings of the Royal Society B and the whole experiment was described there. So, 26 players and 33 people, who didn’t play the games, took part in the test. They all wore skull caps which were recording their brainwaves and eyes moves when people saw a virtual maze with trees and mountains decorations. The participants had to regain those objects.

The results showed that players used their caudate nucleus much more than ordinary people (players – 80,76%, non players – 42,42%). Non-players relied on their hippocampus, which is brain’s spatial memory.

The caudate nucleus is said to be linked with drug and alcohol addiction.

Dr Gregory West, of the University of Montreal, said, those who played a lot of video games were in much higher risk of Alzheimer’s disease than ordinary people.

Nowadays, people all over the world spend about 2 billion hours a week playing video games. That means, each of them spends 10,000 hours in games by the time they are 21. But the influence of active gaming is now beginning to come out.

The brain scans will be further explored and researchers are going to investigate the straight effects of specific action video games on the caudate nucleus and the hippocampus.
