<s>[INST] I am a prek teacher and one of my 4 year old boys turns his head repeatedly left and right non stop...he does it mostly while he s sitting down during learning time. He also rolls his eyes slightly backwards..Also when i ask him a question he only repeats the same thing i say to him. He only draws circles and eats an apple by turning it round and round..What is wrong with him? [/INST] Hi..by what you quote I feel that what he is exhibiting are early signs of autistic spectrum disorder and he need psychological evaluation and expert care. I suggest you advise his parents to take him to a child clinical psychologist and get him evaluated.Regards - Dr. Sumanth </s>
