Prenatal and early postnatal risk factors for autism spectrum disorders

自闭症谱系障碍（ASD）是一种使人衰弱的发育障碍，影响了大约1%的澳大利亚人。我们将研究双胞胎儿童、从妊娠早期就开始跟踪的成年人以及患有自闭症儿童的兄弟姐妹的自闭症样特征，以检验自闭症与产前睾酮水平升高和早期大脑过度发育有关的理论。我们希望能够发现ASD的早期生物学标志物，从而促进患儿的早期识别和干预。

Autism Spectrum Disorder (ASD) is a debilitating developmental disorder affecting around 1% of Australians. We will examine ASD-like traits in twin children, adults followed since early gestation, and siblings of children with ASD, to test the theories that ASD is associated with enhanced levels of prenatal testosterone and early brain overgrowth. We hope to identify early biological markers for ASD, which may promote earlier identification and intervention of affected children.
