The phenomenological presentation of late-onset schizophrenia is a topic of considerable debate. This study aims to look at the clinical presentation of late-onset schizophrenia. Charts of all subjects who received a diagnosis of schizophrenia between January 1990 and December 1993 with age of onset being 45 or more were systematically analysed using the OPCRIT checklist. Of the 89 subjects chosen for analysis, 59 satisfied the ICD-10 DCR criteria for schizophrenia and formed the sample of the study. Of them, 20 were males and 39 were females. The mean age of onset for males was 51.6±5.7 years and for females, 53.2±16.7 years. The commonest phenomenon was persecutory delusion (83%) followed by delusion of influence and hallucinations in any modality (66%each). 53% of the subjects had third person auditory hallucinations, while 42% showed negative symptoms. Delusional perception and thought echo were not found in any subject. The implications of these phenomenological findings are discussed.
迟发性精神分裂症的现象学表现是一个颇具争议的话题。本研究旨在观察迟发性精神分裂症的临床表现。使用 OPCRIT 清单对 1990 年 1 月至 1993 年 12 月期间所有被诊断为精神分裂症且发病年龄为 45 岁及以上的患者的病历进行了系统分析。在选择进行分析的 89 名患者中，59 名符合 ICD-10 DCR 精神分裂症标准，构成了本研究的样本。其中，男性 20 名，女性 39 名。男性发病年龄的平均值为 51.6±5.7 岁，女性为 53.2±16.7 岁。最常见的现象是被害妄想（83%），其次是影响妄想和任何类型的幻觉（各占 66%）。53%的患者有第三人称听觉幻觉，42%有阴性症状。没有发现任何患者存在妄想知觉和思维回声。本文讨论了这些现象学发现的意义。
