How Music Can Prevent Cognitive Decline

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.
