Is palilalia more often related to tourette's or autism spectrum? my child has asd and multiple motor tics started palilalia 6+ months ago.

Statistics unavailab: Palilalia can occur in both. Reports would implicate tourette's as most common, but it has been reported in autism and asperger's. Formal comparative incidence studies appear to be unavailable at this time. Perhaps one of my colleagues in research will comment further.

Much more tourette's: Also given that for tourette's vocal tics are central to the diagnosis along with motor tics. Vocal tics including palilalia, are not the case for the autism spectrum. By the way, echolalia is more common in the autism spectrum. And remember, the cornerstone for autism spectrum is social awkwardness and this is not a requirement for tourette's. Take care.
