Recent studies have found that an unexpectedly large proportion of autistic children have large heads. Anthropometric measures of consecutive clinic attenders with pervasive developmental disorder (PDD), other psychiatric or language disorders were analysed. Similar data were obtained from two schools for language disordered children. These data, combined with those from previous studies, indicate that about one-third of children with PDD have macrocephaly based on current percentile charts; this rate was significantly higher than in children with language disorder alone. The finding was not a consequence of recognizable medical disorders and suggests that PDD is sometimes associated with abnormal physical development.
最近的研究发现，意外有很大比例的自闭症儿童头部较大。对患有广泛性发育障碍（PDD）、其他精神疾病或语言障碍的连续就诊者进行了人体测量分析。从两所语言障碍儿童学校获得了类似数据。这些数据与先前研究的数据相结合，表明根据当前的百分位图表，约三分之一的PDD儿童患有巨头症；这一比例显著高于仅患有语言障碍的儿童。这一发现并非由可识别的医学疾病导致，表明PDD有时与身体发育异常有关。
