Separating hoarding from OCD

Behav Res Ther. 2009 Jun;47(6):520-2. doi: 10.1016/j.brat.2009.02.014. Epub 2009 Mar 3.


There is confusion about the status of excessive hoarding. In particular, there is an unresolved question about whether or not it is a manifestation of obsessive-compulsive disorder (OCD). There are some definite similarities between 'compulsive' hoarding and OCD, but they are outweighed by the differences between them. It is proposed that the matter can be clarified by separating hoarding from OCD, and that this would advance clinical work and research.
