Diagnostic criteria for hoarding disorder in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5)1

APersistent difficulty discarding or parting with personal possessions, regardless of their actual value
BThe difficulty is due to strong urges to save items and/or distress associated with discarding
CThe symptoms result in the accumulation of a large number of possessions, which fill up and clutter active living areas of the home or workplace to the extent that the intended use of those areas is no longer possible. If all living space is uncluttered, it is only because of the interventions of third parties (eg, family members, cleaners, authorities)
DThe symptoms cause clinically significant distress or impairment in social, occupational or other important areas of functioning (including maintaining a safe environment for oneself and others)
EThe hoarding symptoms are not due to a general medical condition (eg, brain injury, cerebral vascular disease)
FThe hoarding symptoms are not restricted to the symptoms of another mental disorder (eg, hoarding due to obsessions in obsessive-compulsive disorder, cognitive deficits in dementia, restricted interests in autism spectrum disorder, food storing in Prader-Willi syndrome)
