Impairment of the serotonergic system during the prodromal phase of Parkinson’s disease – ProdomalPD

Submission summary

Parkinson’s disease is characterized by the dopamine denervation leading to motor symptoms, and spreading of misfolded alpha-synuclein in the brain. However, the serotoninergic system is also affected and has been linked to non-motor symptoms that may precede the motor phase of the disease. The present project aims to further investigate the impairment of the serotoninergic system at the prodromal stage of the disease in carriers of alpha-synuclein gene mutations (rare disease), and, in parallel, in an animal model of prodromal serotoninergic injury. We will investigate by state of the art of PET imaging and deep clinical and behavioral assessment the relationships between impairment of pre and post-synaptic serotonergic markers and the presence and severity of non-motor symptoms. The better understanding of the pathophysiological mechanisms taking place during the prodromal phase of the disease may lead to new therapeutic options to reduce these non-motor symptoms.
