What they
aren't telling you is that piped-in music is probably what put those poor bastards in the loony bin to start with!

If you want to do the opposite; that is to
generate increased aggression, verbal abuse, signs of agitation, repeated banging of fists against mouse pads, and a dramatic increase in the use of profane language I can tell you EXACTLY what you need to do. In fact, I have involuntarily participated in a lengthy research project on this very subject. I'd tell you all about it, but the nurse is here now with my meds.
The traditional thinking in music therapy with dementia is that you appeal to their era. So we would have chosen Vera Lynn or Gracie Fields.
It's interesting that people are able to reduce an entire age bracket to a certain musical genre, or even a performer. I wonder what band\artist people in my "era" will be averaged out to? Weird...
