What is the reason for a child's head shaking?

Patient's question:

Child shakes head

Doctor's answer:

If the child is just playful, it's nothing to worry about. Parents can educate the child properly. If it's unconscious, then it's necessary to consider whether the child might have Tourette syndrome. Childhood Tourette syndrome is a behavioral disorder caused by a functional defect in the extrapyramidal nervous system. Its main manifestations include: squinting, shaking the head and shoulders, waving hands and nodding, kicking legs and twisting the body, and saying dirty words, among others. Severe cases may also involve throat noises, often uncontrollably emitting abnormal sounds like "hmm," "ah," or "cough."
