According to a Study:
- The findings showed that habitual players of action video games had reduction in grey matter in the hippocampus.
- Hippocampus,a key brain area for memory
- This challenged the previously held notion that it may boost brain power.
- In addition,reduce stress and aid in improving symptoms of depression, the researchers said.
- Associate professor at Universite de Montreal (UdeM) IN Canada.
- Said,”video games have shown to benefit certain cognitive systems in the brain, mainly related to visual attention and short-term memory.”
- Further, the study showed that instead of the hippocampus.
- 85% of players tend to increasingly make use of another part of the brain called the striatum to navigate their way through a game.
- Striatum has an area known as the caudate nucleus that acts as a kind of “autopilot” and “reward system” and also helps us form habits and remember how to do things like ride a bicycle.
- However, the more the players use the caudate nucleus, the less they use the hippocampus, and as a result the hippocampus loses cells and atrophies, the researchers rued, in the paper detailed in the journal Molecular Psychiatry.

- If action video games lead to decreases in grey matter in the hippocampus (of young adults).
- Caution should 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, researcher suggested.
- According to the study, patients with Parkinson’s disease combined with dementia.
- As well as those with Alzheimer’s disease, schizophrenia, depression or PTSD.
- All of whom have less grey matter in their hippocampus should “not be advised to (follow) action video game treatments.
