Patients with HD show persistent difficulty discarding or parting with personal possessions, even those apparently useless or of limited value, due to strong urges to save items and the distress and/or indecision associated with discarding. The hoarding causes clinically significant distress or impairment in social, occupational, or other important areas of functioning. Patients with HD also show stronger inheritance, earlier onset and poorer treatment response compared to OCD. However, there has been little information about HD. To clarify the clinical characteristics of HD, we conducted a clinical survey for HD. 【Methods】Participants who are suffering hoarding symptoms were recruited from the Department of Neuropsychiatry, Kyushu University Hospital and the related clinics. The diagnoses of HD were assessed by The Structured Interview for Hoarding Disorder (SIHD). Comorbid axis I disorders were screened by the Structured Clinical Interview for DSM-IV (SCID). Clinical information of each participants such as onset age of hoarding symptom were investigated individually in detail. The study was approved by the local ethics committee, and each participants provided a written informed consent after receiving a complete description of the study. 【Conclusion】Thirty-three participants completed the survey. Among them, twenty-one participants were diagnosed as HD. The mean age of participants with HD were 45.1±13.5. The age of onset were 18.1±12.8. Comorbid axis I disorders are as follows: Major Depression=11, ADHD=5, OCD=2, Bipolar Disorder=2, Panic Disorder=2. The results suggested that HD occurs in adolescence and have a chronic course. Our results also showed that most participants with HD had comorbid mental disorders including depression and ADHD.
