Trodat 1 SPECT and Dopamine Polymorphism

February 8, 2016 updated by: Mordechai Lorberboym Prof, Wolfson Medical Center

Association of Polymorphism in Genes Associated With Control of Dopamine Levels in Parkinson's Disease and Tc-99m-Trodat-1 SPECT Imaging.

The study population will include 100 parkinsonian patients in early stage of disease, with total duration not exeeding 5 years.

The patients will undergo neurologic examination and evaluation of disease severity using the unified PD rating scale. Subsequently a brain SPECT will be performed using Tc-99m-Trodat1.

Detailed Description

The study sample will include 100 Israeli Jewish patients with early idiopathic PD who were not treated with anti-parkinson drugs. The clinical diagnosis will be based on the criteria of the United Kingdom Parkinson Disease Society Brain Bank.5 All patients will undergo Tc-99m-Trodat1 SPECT. The severity of the motor symptoms will be assessed with the Unified PD Rating Scale (UPDRS). Genomic DNA is extracted from peripheral blood leukocytes for genetic analysis.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Disease severity versus genetic polymorphism
Time Frame: 1 year
Correlation of disease severity with polymorphism and with striatal affinity to the DAT ligand.
1 year

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Severity of PD compared to specific striatal DAT activity as measures by Tc-99m Trodat SPECT.
Time Frame: 1 year
For each striatal ROI, mean counts will be measured, and specific TRODAT uptake will be calculated, according to the following formula: Specific TRODAT uptake = (mean activity in ROI - mean Activity in occipital cortex) / mean Activity in occipital cortex).
1 year
