Hoarding often occurs without obsessive-compulsive disorder (OCD), it shows distinguishable neuropsychological and neurobiological correlates and a distinct comorbidity spectrum. Further, it occurs secondarily to other psychiatric and neurobiological disorders. Therefore hoarding disorder has been included as a distinct diagnosis in DSM-5.Neuroimaging studies point to functional and structural abnormalities of networks subserving decision making, attention, action planning and emotional regulation.The cognitive-behavioral model outlines the most important characteristics of pathological hoarding, comprising deficits of information processing, maladaptive beliefs about information processing deficits, maladaptive beliefs about posessions as well as emotional attachment to them accompanied with emotional distress and avoidance.Because of a low willingness for therapy plus a high rate of discontinuation of therapy, a manualized cognitive-behavioral therapy approach for pathological hoarding has been established. It builds on observational learning, cognitive strategies, graduated exposure, response prevention, training/coaching to sort out, and relapse prevention are key components of the treatment. Particularily in case of lacking motivation for any kind of behavioral therapy or other psychological treatments, a pharmacotherapy with SSRIs is recommended.
