People who regularly play action video games could be at increased risk of developing neurological and psychiatric disorders, a study suggests.

The research, published in a Royal Society journal on Wednesday, found that people who played games such as Call of Duty, Grand Theft Auto V and Tomb Raider were more likely to employ navigational strategies associated with decreased grey matter in the hippocampus part of the brain.

Decreased volume in the hippocampus has been associated with disorders such as schizophrenia, post-traumatic stress disorder, depression and Alzheimer’s disease.

The lead study author, Prof Greg West, from the University of Montreal’s department of psychology, said the paper indicated that benefits of video games, such as improved attention and perception, highlighted in previous studies, could come at a price.
