Playing ”shooter" video games weakens the brains of young people and puts them at greater risk of dementia in later life, new research suggests.
Researchers at the University of Montreal scanned the brains of habitual players of action video games and compared them to non-players, finding the gamers had less grey matter.
"If action video games lead to decreases in grey matter in the hippocampus, caution should be exerted when encouraging their use by children, young adults and older adults to promote cognitive skills such as visual short-term memory and visual attention," the scientists wrote.
Gaming has been shown to stimulate another part of the brain called the caudate nucleus, more than the hippocampus.
The region acts as a form of ”autopilot" and also regulates humans' understanding of reward.
The scientists said that the more the caudate nucleus is used, the less use is made of the hippocampus, causing it to lose cells.
They recruited 51 men and 46 women and asked them to play a variety of popular shooter games like Call of Duty, Killzone and Borderlands 2, as well as so-called 3D games such as Super Mario, for a total of 90 hours.
Ninety hours of playing shooter games tended to lead to hippocampus atrophy, however playing for the same duration on 3D challenges, which rely more on spatial orientation instinctive responses, increased grey matter within the hippocampal memory system.
British scientists have cautioned against drawing firm conclusions from the study, highlighting the small number of participants.
