Alzheimer's and Salsa Dancing

My sister, an active social worker who helped families of veterans solve many problems, was diagnosed with Alzheimer's a few years after retiring. During COVID, she and her husband were alone indoors, not actively involved with others to avoid getting sick. It was during that time that she was diagnosed and I think the lack of socialization made her condition worse. She's now in an assisted living facility but was dancing at an independent living facility prior and doing well. Music and dance is very important for Alzheimer's patients.
