The prevalence is estimated at approximately 2–3%, with symptom onset often already occurring in childhood or adolescence. This article provides a structured overview of the epidemiology, etiopathogenesis, typical comorbidities and relevant differential diagnoses of pathological hoarding. A further focus is on evidence-based treatment approaches, in particular disorder-specific cognitive behavioral therapy and the relevance of pharmacotherapy for comorbid conditions. Finally, the substantial psychosocial of pathological hoarding as well as social law are discussed.
