The Application of Audio-Visual Entrainment for the Treatment of Seniors’ Issues

by David Siever, Edmonton, ALberta, Canada

As the majority of the North American population continues to age, cognitive decline in older adults is becoming an ever-growing concern. With the increase in age comes a decrease in cerebral blood flow, slowing of the brain's alpha rhythm and increased theta activity. These changes correlate with reduced cognition, spanning memory, problem solving ability, difficulty with language and speech, and locomotion. Chronic stress impairs hippocampal function leading to a host of disorders including Alzheimer's disease. The left hemisphere of the brain has a tendency to loose functionality before the right side, which may enhance spatial creativity and when coupled with fears and feelings of helplessness, may also bring forth depression. Preliminary studies of Audio-visual entrainment (AVE) have shown this technique to be promising in the treatment of age-related issues common with our senior citizens. AVE is proving to rehabilitate cognitive function in seniors and the best application of AVE may be that as a prophylactic against cognitive decline.
