Rapidly oscillating gamma waves, which reverberate at frequencies of 30 to 120 hertz, are of particular interest in Alzheimer’s research, because their period of oscillation is well matched to the hundredth-of-a-second time frame of synaptic signaling in neural circuits. Study finds light and sound therapy could help fight Alzheimer’s disease. It is known that Alzheimer's disease (AD) patients have significant disruptions in brain waves, especially the gamma frequency (~30 - 100 Hz) waves. In extensive testing in Tsai’s lab with multiple mouse models of Alzheimer’s, the light and sound stimulation technique, called Gamma ENtrainment Using Sensory Stimuli , improved cognition and memory, prevented neurodegeneration, and reduced amyloid and tau protein buildups. The restoration of these waves could one day be an option for Alzheimer’s disease treatment, according to a study outlined on The Scientist . His research has linked impairments in these neurons with weakened gamma waves and Alzheimer’s-like dysfunction in mice (5). Disruptions to these waves have been found in various neurological disorders, not just Alzheimer’s. By exposing mice to a unique combination of light and sound, MIT neuroscientists have shown that they can improve cognitive and memory impairments similar to those seen in Alzheimer’s patients. They think that the strobe-induced changes could prove useful in dealing with Alzheimer’s. These gamma waves are diminished in Alzheimer's disease. A feasibility trial of gamma sensory flicker for patients with prodromal Alzheimer’s disease. Brain wave stimulation may improve Alzheimer’s symptoms.
