Head nodding/head-shaking is a tic experienced by many people with tic disorders. It can resemble and/or be identical to neck-related tics, creating similar movements.
Is head-nodding and shaking a motor or vocal tic?
Would this be a simple or complex tic?
As a stand-alone tic, this would usually be considered simple. This changes if more muscles are used, or combined with additional tics. This could be moving a limb or saying a word or phrase.

What to look out for
Individuals with this tic may find themselves prone to headaches. Repetitive movements may cause dizziness and nausea. More severe movements may also affect the neck region.
The neck is a very sensitive area, and prone to injuries. Tics can slow down the healing process of injuries to the neck or head region.
It would be advised to see a specialist for advice if this is the case.
Is this caused by Tourette syndrome?
This may be a symptom of Tourette if combined with at least one other motor tic and one vocal tic. These have to be present for one year.
