The work group is recommending that this be included in DSM-5 but is still examining the evidence as to whether inclusion is merited in the main manual or in an Appendix for Further Research.
-Persistent difficulty discarding or parting with personal possessions, even those of apparently useless or limited value, due to strong urges to save items, distress, and/or indecision associated with discarding.
-The symptoms result in the accumulation of a large number of possessions that fill up and clutter the active living areas of the home, workplace, or other personal surroundings (e.g., office, vehicle, yard) and prevent normal use of the space. If all living areas are uncluttered, it is only because of others’ efforts (e.g., family members, authorities) to keep these areas free of possessions.
-The symptoms cause clinically significant distress or impairment in social, occupational, or other important areas of functioning (including maintaining a safe environment for self and others).
-The hoarding symptoms are not due to a general medical condition (e.g., brain injury, cerebrovascular disease).
-The hoarding symptoms are not restricted to the symptoms of another mental disorder (e.g., hoarding due to obsessions in Obsessive-Compulsive Disorder, lack of motivation in Major Depressive Disorder, delusions in Schizophrenia or another Psychotic Disorder, cognitive deficits in Dementia, restricted interests in Autistic Disorder, food storing in Prader-Willi Syndrome).
With Excessive Acquisition: If symptoms are accompanied by excessive collecting or buying or stealing of items that are not needed or for which there is no available space.

Delusional: Completely convinced that hoarding-related beliefs and behaviors (pertaining to difficulty discarding items, clutter, or excessive acquisition) are not problematic despite evidence to the contrary..." Link
