Takeaway
Different pediatric dystonia etiologies display signature patterns of glucose metabolism.
Why this matters?
Pediatric dystonia remains under-recognized and difficult to diagnose and manage. Functional imaging has revealed abnormalities in the sensorimotor network and may help to map out the underlying pathology.
These findings lay down the groundwork for understanding the pathogenesis of dystonia and indicate FDG-PET as a useful tool for assessing therapeutic efficacy or predict outcomes.
