Study Details

Study Description

Brief Summary

AIM: To assess synaptic density and to investigate the potential relationship of regional synaptic loss with motor and non-motor symptoms and with disease progression in the human brain in vivo in patients with PD.

DESIGN: We will include 30 PD patients and 20 healthy controls. All subjects will undergo a clinical examination, with comprehensive assessment of motor and non-motor symptoms, and imaging evaluation consisting of 11C-UCB-J PET-CT and 18F-FE-PE2I PET-MR at baseline and after 2 years.

Arms and Interventions

Arm Intervention/Treatment
Experimental: PD patients

At baseline and 2-year follow-up

Other: 11C-UCB-J PET-CT
Positron Emission Tomography (PET) of synaptic vesicle protein 2A (SV2A) using the radioligand 11C-UCB-J.

Other: 18F-PE2I PET-MR
Positron Emission Tomography (PET) of dopamine transporter (DAT) using the radioligand 18F-FE-PE2I, and brain MRI performed simultaneously.

Outcome Measures

Primary Outcome Measures

  1. Baseline differences in synaptic density. [Data analysis wel be done when all subjects have undergone the baseline evaluation.]

    Baseline differences (%) in synaptic density between patients and controls.

  2. Correlations between clinical scores and synaptic density. [Data analysis wel be done when all subjects have undergone the 2-year follow-up evaluation.]

    Correlations between clinical scores and synaptic density in the patient group.

  3. Differences in the rate of decline of synaptic density. [Data analysis wel be done when all subjects have undergone the 2-year follow-up evaluation.]

    Differences (%) in the rate of decline of synaptic density between patients and controls.

  4. Correlations between progression of the clinical scores and decline of synaptic density. [Data analysis wel be done when all subjects have undergone the 2-year follow-up evaluation.]

    Correlations between progression of the clinical scores and decline of synaptic density in the patient group.

Secondary Outcome Measures

  1. Baseline differences in DAT levels. [Data analysis wel be done when all subjects have undergone the baseline evaluation.]

    Baseline differences (%) in DAT levels between patients and controls.

  2. Correlations between clinical scores and DAT levels. [Data analysis wel be done when all subjects have undergone the 2-year follow-up evaluation.]

    Correlations between clinical scores and DAT levels in the patient group.

  3. Differences in the rate of decline of global and DAT levels. [Data analysis wel be done when all subjects have undergone the 2-year follow-up evaluation.]

    Differences (%) in the rate of decline of global and DAT levels between patients and controls.

  4. Correlations between progression of the clinical scores and decline of DAT levels. [Data analysis wel be done when all subjects have undergone the 2-year follow-up evaluation.]

    Correlations between progression of the clinical scores and decline of DAT levels in the patient group.
