Question: Question: The parents of a 2-year-old girl consult because they are concerned about their daughter's development. They have observed that approximately from 18 months, their behavior is different from that of other children of their age. Until then, they had attributed their limited interaction to the fact that they were becoming more independent, and the lack of language development, to which they were not yet enrolled. In the consultation you observe that the girl does not respond when she calls her by her name, shows little eye contact, performs vocalizations without communicative intention, and does not look at where the parents point her. Given these findings, all of the following statements are true, EXCEPT one: 
 Options:  <1> Parents should be reassured, recommended schooling as soon as possible, and arrange a follow-up in 3 months. <2> The most likely diagnosis is autistic spectrum disorder. <3> A diagnostic evaluation must be carried out by a team with experience in autism. <4> Appropriate early intervention is recommended. <5> The origin of the disorder is multifactorial.

Answer: 1
