developmental retardation

基本解释

Symptoms can vary from normal to severe developmental delay or mental retardation.
症状变化较大，可以是正常的或严重的发育延迟或智力低下。
A person with cerebral palsy may have average intelligence or can have severe developmental delays or mental retardation.
脑瘫患者可能会拥有平均智力水平，也可能智力发育极为迟缓。
However, muscle spasms, hyperreflexia, refractory epilepsy, developmental delay, and mental retardation are common in children afflicted with the disorder.
然而，肌痉挛、反射亢进、顽固性癫痫、发育迟缓、智力低下是常见的症状。

So, it's not really a developmental ... it's not really a developmental delay in the way that it might make sense to think about certain forms of retardation.
孤独症并非发展延迟,不应当把它理解为,某种形式的发育迟缓
