Can virtual reality boost brain power in movement disorders?

This study tested whether using immersive virtual reality or computer-based brain training could improve thinking and memory in people with Parkinson's or Huntington's disease who have mild cognitive problems. Sixty-four participants were randomly assigned to one of three groups: virtual reality exercises, computer-based cognitive stimulation, or music therapy. The goal was to see if the high-tech approaches could delay worsening of cognitive function better than music therapy.
