Point and say "Bluetooth"

In my lecture today we were covering psychological disorders, and specifically schizophrenia. When I talked about people talking to themselves and responding to stimuli that isn't there, one of my students brought up that it sounded a lot like customers at his store with bluetooth headsets. 

He stated that he saw many people in his store walking around who appear to be talking to themselves. And when they would get into arguments by themselves, it looked even worse. People yell into the air. When others looked at them with puzzled expressions, they simply point to their ear and say "bluetooth".

I got to thinking, what if we gave every delusional schizophrenic a bluetooth looking device. It wouldn't need to be operational, just pulse light in metered intervals. I wonder if schizophrenics would be viewed  and treated with greater understanding, and if they were treated with greater understanding, would they still behave so bizarrely? 

I suspect not, but it was intriguing to think about.
