My mission with seniors started when an avocation for singing turned into an advocacy for older adults. I still perform in facilities and use songs in my keynotes. I know firsthand the value of music therapy on dementia and Alzheimer's patients.
This NYT article validates it.
When looking at a care facility take time to participate and evaluate the activity programs. There are some facilities that still meet the stereotype of plopping people by a television and leaving them there. Then there are the progressive ones. Those that use progressive methods like intergenerational programming and music therapy are able to unlock something inside our elders and even halt some of the steady progress these conditions inflict on people.
