尽管自闭症谱系障碍 (ASD) 的研究取得了进展,但对 ASD 生物学基础的了解以及确定新型有效治疗靶点的了解仍然有限。自闭症的主要生物学理论之一是皮质过度兴奋模型。虽然大量的遗传和表观遗传研究支持这一模型,但这种特殊的生物学改变与自闭症谱系障碍的已知表型之间的关系尚不清楚。通过使用感觉处理改变的例子,这篇综述说明了皮质兴奋性如何影响神经过程,最终导致自闭症谱系障碍的一些核心临床表型。还讨论了皮质兴奋性模型在转化研究和药物开发中的应用。
Despite the progress that has been made in research on autism spectrum disorders (ASD), the understanding of the biological basis of ASD to identify targets for novel, effective treatment remains limited. One of the leading biological theories of autism is a model of cortical hyperexcitability. While numerous genetic and epigenetic studies support this model, how this particular biological alteration relates to known phenotypes in ASD is not well established. Using examples of sensory processing alterations, this review illustrates how cortical excitability may affect neural processes to result eventually in some core clinical phenotypes in ASD. Applications of the cortical excitability model for translational research and drug development are also discussed.
