Five patients with late-life onset of schizophrenic symptomatology (late-life paraphrenia) were found to have occult organic disorders. Although it was not possible to prove that the organic disorders were causal in these patients, none had any psychiatric illness until late in life and none had any significant risk factors for developing schizophrenia. This study demonstrates the need to investigate the medical and neurologic condition of any elderly patient presenting with a new onset of delusions. Modern investigative techniques may permit more accurate classification (and therapy) of some patients with late-life paraphrenia.
五名出现迟发性精神分裂症症状（晚发性妄想痴呆）的患者被发现患有隐匿性器质性疾病。尽管无法证明这些器质性疾病在这些患者中具有因果关系，但他们在晚年之前均无任何精神疾病，也没有任何患精神分裂症的重大风险因素。这项研究表明，有必要对任何新发妄想的老年患者的医学和神经状况进行调查。现代检测技术可能会使一些晚发性妄想痴呆患者得到更准确的分类（以及治疗）。
