Childhood Music Lessons May Provide Lifelong Boost in Brain Functioning

ScienceDaily (Apr. 20, 2011) — Those childhood music lessons could pay off decades later -- even for those who no longer play an instrument -- by keeping the mind sharper as people age, according to a preliminary study published by the American Psychological Association.

The study recruited 70 healthy adults age 60 to 83 who were divided into groups based on their levels of musical experience. The musicians performed better on several cognitive tests than individuals who had never studied an instrument or learned how to read music. The research findings were published online in the APA journal Neuropsychology.

"Musical activity throughout life may serve as a challenging cognitive exercise, making your brain fitter and more capable of accommodating the challenges of aging," said lead researcher Brenda Hanna-Pladdy, PhD. "Since studying an instrument requires years of practice and learning, it may create alternate connections in the brain that could compensate for cognitive declines as we get older."

While much research has been done on the cognitive benefits of musical activity by children, this is the first study to examine whether those benefits can extend across a lifetime, said Hanna-Pladdy, a clinical neuropsychologist who conducted the study with cognitive psychologist Alicia MacKay, PhD, at the University of Kansas Medical Center.

The three groups of study participants included individuals with no musical training; with one to nine years of musical study; or with at least 10 years of musical training. All of the participants had similar levels of education and fitness and didn't show any evidence of Alzheimer's disease.

All of the musicians were amateurs who began playing an instrument at about 10 years of age. More than half played the piano while approximately a quarter had studied woodwind instruments such as the flute or clarinet. Smaller numbers performed with stringed instruments, percussion or brass instruments.

The high-level musicians who had studied the longest performed the best on the cognitive tests, followed by the low-level musicians and non-musicians, revealing a trend relating to years of musical practice. The high-level musicians had statistically significant higher scores than the non-musicians on cognitive tests relating to visuospatial memory, naming objects and cognitive flexibility, or the brain's ability to adapt to new information.
