Differential diagnosis between schizophrenia and pervasive developmental disorder (PDD) including Asperger's syndrome, needs evaluation of apparently similar symptoms among the two disorders and careful collection of information about developmental history of each patient. Some conditions that have been traditionally regarded as schizophrenia, seem to have overlapping parts with those of PDD. An example of them is schizophrenia--like symptoms observed occasionally in individuals with PDD. The relationship of the two disorders remains to be investigated. I present a case of an adolescent with early symptoms of schizophrenia, in whom there seems to have been PDD symptoms in his early childhood. The issue of the differential diagnosis of the two disorders is discussed on the basis of the case. It is sometimes difficult to diagnose PDD in mildest cases in adolescence or adulthood, presumably because they show subtle symptoms in their early childhood in terms of interpersonal relationships and caretakers of them are likely to fail to recognize their problems, which may cause difficulty in sufficient collection of information about their early childhood.
精神分裂症与广泛性发育障碍（PDD）（包括阿斯伯格综合征）之间的鉴别诊断，需要评估这两种疾病中明显相似的症状，并仔细收集每位患者发育史的信息。一些传统上被视为精神分裂症的病症，似乎与PDD有重叠部分。其中一个例子是在PDD患者中偶尔观察到的精神分裂症样症状。这两种疾病的关系仍有待研究。我介绍一例患有精神分裂症早期症状的青少年病例，其在幼儿期似乎存在PDD症状。基于该病例讨论了这两种疾病的鉴别诊断问题。在青少年期或成年期的最轻微病例中，有时难以诊断PDD，大概是因为他们在幼儿期人际关系方面表现出微妙的症状，并且他们的照顾者可能未能认识到他们的问题，这可能导致难以充分收集有关其幼儿期的信息。
