Research has shown that having musical training and listening to or playing music in old age can help keep the brain healthy especially as it ages. Since listening to music is like exercising the brain, one can expect the benefits of better memory and mental sharpness as they age. [4]
Even people who have some form of brain damage can regain partial or full access to memories (depending on severity) by listening to music, as listening can help draw on old memories and neurological patterns due to the fact that the rhythm and sounds of music stay within the core of the mind for a long time.
