SCOTTSDALE, Ariz., March 5 /PRNewswire/ -- Brain fitness training makes you a better listener says Michael Merzenich, PhD, who delivers the Carhart Memorial Lecture today at the American Auditory Society annual meeting in Scottsdale, Arizona.
Dr. Merzenich's talk is entitled "Hearing and the Brain Plasticity Revolution." He will discuss recent results from the IMPACT Study, which are being published next month in The Journal of the American Geriatrics Society. An advance copy of the breakthrough study, led by researchers from the
A total of 487 healthy adults over the age of 65 participated in the randomized controlled trial. Half were assigned to a group that trained for a total of 40 hours over the course of 8 weeks on cognitive training software - the Brain Fitness Program(TM) from Posit Science(R). The other half spent an equal amount of time learning from educational lectures delivered via computer and followed by quizzes.
The Brain Fitness Program was developed by a global team of neuroscientists to improve auditory processing and memory. It consists of six exercises done on a computer and is based on the science of brain plasticity - the ability of the brain to change in response to cognitive stimulation.
The study found that participants who trained on the software more than doubled their auditory processing speed, with an average increase of 131%. They also saw gains on standard measures of memory and attention of 10 years, on average. Perhaps most importantly, these changes were big enough that participants reported significant improvements in every day activities (such as remembering what people said or understanding conversations in noisy restaurants). The gains of the brain exercise group were clinically significant; the gains of the lecture group were significantly smaller and not clinically significant.
Treva Kean Strauss, aged 82, of Novato, California participated in the brain exercise half of the study. "After participating in the IMPACT study I saw improvements in my memory, my attention and even my hearing," said Ms. Strauss. "It was a wonderful experience."
When speech comes in more rapidly than the brain can process it reliably, or when it is processed with degraded accuracy, it results in people saying they missed what was said. They may attribute it to a bad phone connection, to a noisy room or to someone not speaking clearly. These problems in hearing are not really problems with reception by the ear, rather they are problems in brain processing. Such difficulties commonly lead to difficulty in hearing, in being attentive and in remembering what was said.
By addressing the speed and accuracy of auditory processing, the software improves the ability to hear in common real life situations where people may speak quickly or in noisy environments. The recent study showed that better auditory signal processing goes beyond making someone a good listener to actually improving memory and attention - leading to fuller function in every day life.
"This is the beginning of a revolution in brain health," said Dr. Merzenich.
