Between February and May 2015 Doctors for Peace Onlus, in collaboration with 7 theater companies coordinated by the Gino Franzi Company, proposed to the guests of the Le Betulle Service Center for the Elderly a review of 8 shows. A scientific commission subjected 20 spectators to cognitive tests before and after the review to evaluate the possible therapeutic effects of music and theater, in the hypothesis that cognitive, sensory and emotional stimuli can slow down cognitive decline.
