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.
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.
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: the dorsolateral prefrontal cortex that controls planning, decision-making and inhibition; the cerebellum that plays a major role in motor control and balance; and the hippocampus, the centre of spatial and episodic memory.
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.
