Summary: Using the classic Nintendo game, Super Mario 64, researchers discover playing 3D platform games could help older brains to stave off mild cognitive impairment. Researchers report older people who played the video game had gray matter increases in the cerebellum, hippocampus and dorsolateral prefrontal cortex.

If you’re between 55 and 75 years old, you may want to try playing 3D platform games like Super Mario 64 to stave off mild cognitive impairment and perhaps even prevent Alzheimer’s disease.
That’s the finding of a new Canadian study by Université de Montréal psychology professors Gregory West, Sylvie Belleville and Isabelle Peretz. Published in PLOS ONE, it was done in cooperation with the Institut universitaire de gériatrie de Montréal (IUGM), Benjamin Rich Zendel of Memorial University in Newfoundland, and Véronique Bohbot of Montreal’s Douglas Hospital Research Centre.
In two separate studies, in 2014 and 2017, young adults in their twenties were asked to play 3D video games of logic and puzzles on platforms like Super Mario 64. Findings showed that the gray matter in their hippocampus increased after training.
The hippocampus is the region of the brain primarily associated with spatial and episodic memory, a key factor in long-term cognitive health. The gray matter it contains acts as a marker for neurological disorders that can occur over time, including mild cognitive impairment and Alzheimer’s.
West and his colleagues wanted to see if the results could be replicated among healthy seniors.
The research team recruited 33 people, ages 55 to 75, who were randomly assigned to three separate groups. Participants were instructed to play Super Mario 64 for 30 minutes a day, five days a week, take piano lessons (for the first time in their life) with the same frequency and in the same sequence, or not perform any particular task.
The experiment lasted six months and was conducted in the participants’ homes, where the consoles and pianos, provided by West’s team, were installed.
The researchers evaluated the effects of the experiment at the beginning and at the end of the exercise, six months later, using two different measurements: cognitive performance tests and magnetic resonance imaging (MRI) to measure variations in the volume of gray matter. This enabled them to observe brain activity and any changes in three areas:
According to the MRI test results, only the participants in the video-game cohort saw increases in gray matter volume in the hippocampus and cerebellum. Their short-term memory also improved.
The tests also revealed gray matter increases in the dorsolateral prefrontal cortex and cerebellum of the participants who took piano lessons, whereas some degree of atrophy was noted in all three areas of the brain among those in the passive control group.
What mechanism triggers increases in gray matter, especially in the hippocampus, after playing video games? “3-D video games engage the hippocampus into creating a cognitive map, or a mental representation, of the virtual environment that the brain is exploring.,” said West. “Several studies suggest stimulation of the hippocampus increases both functional activity and gray matter within this region.”
Conversely, when the brain is not learning new things, gray matter atrophies as people age. “The good news is that we can reverse those effects and increase volume by learning something new, and games like Super Mario 64, which activate the hippocampus, seem to hold some potential in that respect,” said West. Added Belleville: “These findings can also be used to drive future research on Alzheimer’s, since there is a link between the volume of the hippocampus and the risk of developing the disease.”
“It remains to be seen,” concluded West, “whether it is specifically brain activity associated with spatial memory that affects plasticity, or whether it’s simply a matter of learning something new.”

Playing Super Mario 64 increases hippocampal grey matter in older adults
Maintaining grey matter within the hippocampus is important for healthy cognition. Playing 3D-platform video games has previously been shown to promote grey matter in the hippocampus in younger adults. In the current study, we tested the impact of 3D-platform video game training (i.e., Super Mario 64) on grey matter in the hippocampus, cerebellum, and the dorsolateral prefrontal cortex (DLPFC) of older adults. Older adults who were 55 to 75 years of age were randomized into three groups. The video game experimental group (VID; n = 8) engaged in a 3D-platform video game training over a period of 6 months. Additionally, an active control group took a series of self-directed, computerized music (piano) lessons (MUS; n = 12), while a no-contact control group did not engage in any intervention (CON; n = 13). After training, a within-subject increase in grey matter within the hippocampus was significant only in the VID training group, replicating results observed in younger adults. Active control MUS training did, however, lead to a within-subject increase in the DLPFC, while both the VID and MUS training produced growth in the cerebellum. In contrast, the CON group displayed significant grey matter loss in the hippocampus, cerebellum and the DLPFC.
