ASD流行病学调查发表了2000-2009年平均发生率为20.6/10000，范围从7.2到40.5/10000（fombonne，2009）。最受影响的孩子留在ASDs是成年人，有独立生活，难就业，社会关系和精神健康（Howlin，古德，赫顿& Rutter，2004）。尽管它的高患病率和不良的结果，它代表的概念和诊断的挑战，关于基因和神经化学的病因，有针对性的干预和有效的神经。
自闭症谱系障碍（ASD）是一种复杂的神经发育障碍，含五个亚型：孤独症、阿斯伯格症、雷特症、童年瓦解性障碍和广泛性发育障碍另有规定（美国精神病学协会，1994）。那些有自闭症的孩子显示重复的行为，并在社会交往障碍，沟通。
自闭症是一组疾病，患病率增加。然而，诊断需要研究消除辩论；遗传学和神经化学的病因仍不清楚；没有因备受争议的诊断和评价指导治疗，和未知的neruochemical病因。更多的研究应该进行有效的病因针对性治疗有望治愈ASDs。

Autism spectrum disorder (ASD) is a type of complex neurodevelopment disorders, containing five subtypes: autistic disorder, Asperger disorder, Rett disorder, childhood disintegrative disorder and pervasive developmental disorder not otherwise specified (American Psychiatric Association, 1994). Children who have ASDs display repetitive behaviors, and have deficits in social interaction, communication.
The average prevalence of ASD in epidemiological surveys published from 2000-2009 was 20.6/10,000, ranging from 7.2 to 40.5/10,000 (Fombonne, 2009). Most affected children remain with ASDs to be adults, who have trouble in independent living, employment, social relationships, and mental health (Howlin, Goode, Hutton & Rutter, 2004). Despite its high prevalence and adverse outcomes, it represents challenges in the conceptualization and diagnosis, etiology about genes and neurochemistry, and effective neurally-targeted intervention.

ASDs are a group of disorders, increasing in prevalence. However, diagnosis needs research to eliminate debates; the etiology about genetics and neurochemistry is still unclear; there is no guideline treatment due to the controversial diagnosis and assessment, and the unknown neruochemical etiology. More researches should be carried out and effective etiology-targeted treatment are expected to cure ASDs.
