Abnormal movements in infants

Abnormal movements in infants

The world of infant movements is very diverse. Many of them, although they may seem strange to parents, are completely normal. However, there are certain types of involuntary, repetitive movements that can be a sign of neurological problems and require attention.

What should be considered abnormal movements?

• Stereotypies: These are rhythmic, repetitive movements without an obvious purpose (hand flapping, head shaking). Simple stereotypies are common in healthy children and serve as a self‑soothing mechanism. However, pronounced and persistent stereotypies can be one of the symptoms of autism spectrum disorders.
• Infantile spasms (West syndrome): A rare but very serious type of seizure characterized by series of flexion and extension movements.
• Dystonia or chorea: More complex, slow or, conversely, rapid, intermittent movements that indicate involvement of certain brain structures.

How to distinguish from normal?

Unlike tremor, these movements usually do not disappear when the limb is fixed. Unlike seizures, consciousness is more often preserved. If you notice any unusual repetitive movements in your child, the best approach is to record them on video and show them to a pediatrician or a child neurologist.
