Hoarding is common in obsessive-compulsive disorder (OCD), affecting nearly 30% of patients. Hoarding symptoms in OCD are linked to earlier onset, greater severity, and co-occurring conditions, complicating treatment.

Area of Science:

  • Psychiatry
  • Clinical Psychology
  • Behavioral Science

Background:

  • Hoarding is a frequent symptom in obsessive-compulsive disorder (OCD).
  • Patients with hoarding symptoms often exhibit more severe OCD and poorer treatment response.
  • Understanding hoarding within OCD is crucial for effective clinical management.

Purpose of the Study:

  • To investigate the prevalence and characteristics of hoarding symptoms in a cohort of OCD patients.
  • To compare clinical features and co-occurring conditions between OCD patients with and without hoarding symptoms.
  • To explore the familial transmission patterns of hoarding in OCD.

Main Methods:

  • A cross-sectional study involving 126 subjects diagnosed with OCD.
  • Assessment of hoarding symptoms using standardized diagnostic criteria.

  • Comparison of demographic, clinical, and familial data between hoarding and non-hoarding groups.

    • Main Results:

    • Nearly 30% of OCD subjects presented with hoarding symptoms, with a 2:1 male-to-female ratio.
    • Hoarding was associated with earlier age at onset, increased OCD symptom severity, and specific symptom subtypes (symmetry obsessions, counting/ordering compulsions).
    • Hoarders showed higher rates of social phobia, personality disorders, pathological grooming, and a family history of hoarding and tics.

    Conclusions:

    • Hoarding symptoms in OCD may indicate a distinct clinical subgroup with more severe illness and comorbid conditions.
    • The presence of hoarding complicates OCD treatment due to increased symptom severity and co-occurring disorders.
    • Hoarding appears to have a familial component in some OCD-affected families, suggesting potential genetic or shared environmental influences.
