Abstract:
Juvenile-onset dystonia that improves after levodopa may occur in both dopa-responsive dystonia (DRD) and juvenile parkinsonism (JP), clinically similar conditions with different prognoses and management goals. The authors show normal striatal uptake of the dopamine transporter ligand FP-CIT with SPECT in a clinically atypical case of DRD, in contrast to the reduced uptake observed in JP.
