简要总结

The research aim to study in detail the motor, cognitive and affective modifications of Parkinsonian patients (compared to control subjects) at a moderate stage of the disease and to analyze by positron emission tomography (PET) imaging with the specific radioligand [11C]SB207145 the expression levels of this 5-HT4 receptor. At the same time, the study will monitor the impact of the 5-HTTLPR polymorphisms of Serotonin Transporter (SERT) and Brain-derived neurotrophic factor (BDNF) Val66Met on the expression of the 5-HT4 receptor in subjects.
