Organic delusional disorder (ODD) is rarely diagnosed in psychiatric in-patients, and may be misdiagnosed as delusional disorder (DD) from a similar clinical presentation. The aim of the present study was to investigate the characteristics of ODD and to make a comparison with those of DD patients. Patients who conformed to DSM-III-R criteria for ODD were recruited from an 8-year psychiatric in-patient database. Matching controls were DD patients admitted over the same time period. The prevalence of ODD according to DSM-III-R criteria was 0.4% of total admissions and 2.9% of organic mental disorders. Compared to DD patients, ODD patients less often had a family psychiatric history, and had an older age of onset of psychiatric disorder, longer hospital stays and lower treatment dosage of antipsychotic drugs. It is suggested that a detailed medical history and examination are needed in patients with delusion, especially in patients with a late onset of psychiatric symptoms and no family psychiatric history.
器质性妄想障碍（ODD）在精神科住院患者中很少被诊断出来，并且可能由于相似的临床表现而被误诊为妄想障碍（DD）。本研究的目的是调查ODD的特征，并与DD患者的特征进行比较。符合ODD的《精神疾病诊断与统计手册第三版修订版》（DSM-III-R）标准的患者是从一个8年的精神科住院患者数据库中招募的。匹配的对照组是同期入院的DD患者。根据DSM-III-R标准，ODD的患病率在总入院患者中为0.4%，在器质性精神障碍患者中为2.9%。与DD患者相比，ODD患者较少有家族精神病史，精神障碍的起病年龄较大，住院时间较长，抗精神病药物的治疗剂量较低。建议对有妄想的患者，尤其是精神症状起病较晚且无家族精神病史的患者，进行详细的病史询问和检查。
