[Articles] Serotonin and dopamine transporter PET changes in the premotor phase of parkinsonism: cross-sectional studies

Dopaminergic and serotonergic changes progress in a similar fashion in LRRK2 mutation carriers with manifest Parkinson's disease and individuals with sporadic Parkinson's disease, but LRRK2 mutation carriers without manifest Parkinson's disease show increased serotonin transporter binding in the striatum, brainstem, and hypothalamus, possibly reflecting compensatory changes in serotonergic innervation preceding the motor onset of Parkinson's disease. Increased serotonergic innervation might contribute to clinical differences in LRRK2 Parkinson's disease, including the emergence of non-motor symptoms and, potentially, differences in the long-term response to levodopa.
