Hoarding disorder: a new diagnosis for DSM-V?

Area of Science:

• Psychiatry
• Clinical Psychology
• Mental Health

Background:

• Hoarding is currently a diagnostic criterion for obsessive-compulsive personality disorder (OCPD) in DSM-IV-TR.
• Extreme hoarding may lead to a diagnosis of obsessive-compulsive disorder (OCD), with potential co-diagnosis of OCPD and OCD.
• Compulsive hoarding frequently occurs independently of OCD and OCPD, suggesting it may be a distinct condition.

Purpose of the Study:

• To review literature on compulsive hoarding.
• To evaluate its relationship with OCD and OCPD.
• To recommend classification for DSM-V.

Main Methods:

• Literature review focused on compulsive hoarding.
• Analysis of diagnostic criteria in DSM-IV-TR.
• Discussion of potential DSM-V classifications.

Main Results:

• Evidence supports classifying compulsive hoarding as a separate disorder.
• A provisional diagnosis of "hoarding disorder" is recommended.
• Potential classification as an obsessive-compulsive spectrum disorder is considered.

Conclusions:

• The creation of "hoarding disorder" in DSM-V is recommended.
• This new diagnosis could enhance public awareness and clinical identification.
• It is expected to stimulate research and the development of targeted treatments.
