Visual and acoustic interventions for improving mental health in advanced age

Data accumulated in the last years indicate that certain visual and acoustic interventions are of geroprotective potential. Among them are bright light, white noise, and also rhythmic sensory stimulation (flickering light, binaural rhythms), etc. It should be noted that visual and acoustic interventions are simple in use, safe and practically do not have adverse side effects and do not need special medical control. Here, we review the studies on using the visual and acoustic interventions for improving mental health with regard to the advanced age and age-related pathology. We also discuss possible mechanisms of their therapeutic action and points for the future investigations.
