My 29 year old daughter is on Disability for Asperger s syndrome, she has gotten significantly worse past 2 years with one new strange behavior of running water in sink continuously. At first we thought it was to drown out bothersome noise of people talking but she does it in finished apartment in basement she has isolated by herself with full kitchen, bath, etc and will have water running for hours, even when she is on top floor of house, no where near the running water. Any idea why? Maybe something to do with OCD or something?
