If your child has frequent blinking, eye squeezing or eyebrow raising for unknown reasons, beware that your child may have a childhood tic disorder.
Tic disorder is a neuropsychiatric disorder that begins in childhood and adolescence and has a clear genetic predisposition. It is a group of unexplained movement disorders, mainly manifested by involuntary, rapid, purposeless muscle motor twitching or vocal twitching in one or more parts, and may be accompanied by hyperactivity, inattention, compulsive movements and thinking or other behavioral symptoms.

The main clinical manifestations are motor or/and vocal twitches, which may occur sequentially or simultaneously. Usually the first symptom is eye, face or head twitching, such as blinking, tilting of the mouth, shaking of the head, etc., and then gradually progresses to the shoulders, limbs or trunk, and may develop from simple motor twitching to complex motor twitching.
