Researchers show the positive impacts of musical activities to counteract brain ageing:
Normal ageing is associated with progressive cognitive decline. But can we train our brain to delay this process? A team from the University of Geneva (UNIGE), HES-SO Geneva and EPFL has discovered that practicing and listening to music can alter cognitive decline in healthy seniors by stimulating the production of grey matter. To achieve these results, the researchers followed over 100 retired people who had never practiced music before. They were enrolled in piano and music awareness training for six months. These results open new prospects for the support of healthy ageing. They are reported in NeuroImage: Reports.
Throughout our lives, our brain remodels itself. Brain morphology and connections change according to the environment and the experiences, for instance when we learn new skills or overcome the consequences of a stroke. However, as we age, this ''brain plasticity'' decreases. The brain also loses grey matter, where our precious neurons are located. This is known as ''brain atrophy''.
Gradually, a cognitive decline appears. Working memory, at the core of many cognitive processes, is one of the cognitive functions suffering the most. Working memory is defined as the process in which we briefly retain and manipulate information in order to achieve a goal, such as remembering a telephone number long enough to write it down or translating a sentence from a foreign language.
[...] The participants were randomly assigned to two groups, regardless of their motivation to play an instrument. The second group had active listening lessons, which focused on instrument recognition and analysis of musical properties in a wide range of musical styles. The classes lasted one hour. Participants in both groups were required to do homework for half an hour a day.
''After six months, we found common effects for both interventions. Neuroimaging revealed an increase in grey matter in four brain regions involved in high-level cognitive functioning in all participants, including cerebellum areas involved in working memory. [...]
However, the researchers also found a difference between the two groups. In the pianists, the volume of grey matter remained stable in the right primary auditory cortex - a key region for sound processing, whereas it decreased in the active listening group. ''In addition, a global brain pattern of atrophy was present in all participants. Therefore, we cannot conclude that musical interventions rejuvenate the brain. They only prevent ageing in specific regions,'' says Damien Marie.

Exercise - any kind - involving muscles and joints and balance is great, but also visual tracking and processing, auditory processing (as in this study), olfactory - whatever still works: use it, or lose it.

You do the music stuff it gets better at music but you still forget the names of new people.
Practice memorizing pi, get better at remembering pi but still forget names.
Practice memorizing names, get better at remember names but still forget other stuff.
The physical exercise and "get enough sleep" stuff apparently does help with memory and brain function though. So does good nutrition.

I've heard some of the music TikTok teens dance to and their cognitive decline seems to start very early and in earnest.

You seem to be saying that cognitive decline can prevent music?

I don't know. The older I get the more of the lyrics of songs I even like I start to forget. The longer it goes the more I just hum along.

The brain is a pattern matching engine. It finds patterns, predicts them and it feels good when the predictions are correct.
Music is the ultimate jumble of predictable patterns: base beat and tempo, recurring chorus, lyrics that rhyme, etc. Our brain loves it. But on the flipside it's also an exercise for it.
