What is Compulisve Hoarding Disorder:
Frost and Hartl (1996) provided the first systematic definition, identifying three characteristics:"(1) the acquisition of, and failure to discard a large number of possessions that appear to be useless or of limited value; (2) living spaces sufficiently cluttered so as to preclude activities for which those spaces were designed; and (3) significant distress or impairment in functioning caused by the hoarding." This definition distinguished hoarding from the collecting of objects generally considered interesting and valuable.
