早期诊断小儿智力低下是有价值的,因为父母可以及时采取合理的扶养方法与其他有关措施。但是大多数此类婴儿往往误以为正常而漏诊。儿科医生通常过高估计此类年幼儿的智能。概括起来,导致智力低下延误诊断的有以下三种情况:第1.逗人喜爱的小孩被漏诊。第2.能走的小孩被漏诊。第3,对于低于一定年龄的小儿错误地认为“太年幼而不适于检查。” Early diagnosis of children with mental retardation is valuable because parents can take timely and reasonable support methods and other relevant measures. But most of these babies often mistakenly think they are misdiagnosed. Pediatricians often overestimate the intelligence of such young children. To sum up, there are three cases of delayed diagnosis of mental retardation: 1. The cute kid is missed. The second child can be missed. Third, children younger than a certain age mistakenly think “too young to check.”
