This video answers the questions: What is Hoarding Disorder? How can Hoarding Disorder be differentiated from ObsessiveCompulsive Disorder (OCD), ObsessiveCompulsive Personality Disorder (OCPD), and Autism Spectrum Disorder (ASD)?

Hoarding Disorder Criteria from DSM5:

A: persistent difficulty discarding possessions, regardless of value
B: the difficulty we see with criterion A is due to a perceived need to save the items and to distress associated with discarding those items
C: the difficulty results in the accumulation of possessions that congest and clutter active living areas and substantially compromises their intended use. If living areas are uncluttered it’s only because of thirdparty intervention, like family members
D: clinically significant distress
E: not attributable to a medical condition like a brain injury
F: not explained by the symptoms of another mental disorder like OCD, MDD, schizophrenia, or autism
specifiers: with excessive acquisition, with good or fair insight, with poor insight, with absent insight/delusional beliefs
