See if you can get your family member/friend into the Mclean OCDI in Boston. His/her insurance might cover it, and it's widely regarded as the best program for people with OCD in the country.http://www.mclean.harvard.edu/patient/adult/ocd.php
My parents pressured me to go, because I had been dealing with intrusive bad thoughts (a form of OCD). But I only stayed a week, because I didn't think whatever I had was close to as bad as what the other patients had. Anyway, that's how I came to Boston in the first place.
Thank you for the thought, but OCD and Hoarding are totally different beasts. Recent studies, and the major specialists of Hoarding have all come to the conclusion that while Hoarding used to be seen as a subset of OCD, they are entirely different in terms of associated sensations, brain chemistry, and behavior patterns, and that treatments for OCD and Hoarding are not at all the same.
Hmmmmm, I was in therapy with an OCD specialist only a few months ago, and that's certainly not the impression I got. Could be totally wrong though.
