Clinical Trial: A Study of Brain Imaging with Nuclear Medicine Technology in Individuals with and At Risk for Parkinson''s Disease

This study is currently recruiting patients.

Sponsors and Collaborators: Institute for Neurodegenerative Disorders
Indiana University
Albany Medical Center
Information provided by: Institute for Neurodegenerative Disorders


This study involves study participants who have been clinically diagnosed with parkinsonian syndrome or who are at-risk for parkinsonian syndrome, have a family history of parkinsonian syndrome or exposure to environmental toxins potentially associated with parkinsonian syndrome. Participants will have brain imaging to assess dopamine transporter density. The imaging data coupled with family history and environmental exposure data may provide important information about potential risk factors for parkinsonian syndrome.
Condition Intervention Phase
Parkinsonian Syndrome
 Procedure: [123I]ß CIT and SPECT imaging
Phase II

MedlinePlus related topics:  Brain Diseases;   Movement Disorders

Study Type: Interventional
Study Design: Diagnostic, Non-Randomized, Open Label, Active Control, Single Group Assignment, Safety/Efficacy Study

Official Title: Dynamic SPECT Imaging with [123I] B-CIT in Individuals with Parkinsonian Syndrome (PS) and in Individuals At Risk for Parkinsonian Syndrome

Further Study Details: 
Primary Outcomes: CIT uptake is the Specific: Nondisplaceable striatal uptake ratio
Secondary Outcomes: CIT uptake measures from at-risk individuals will be compared with healthy subjects.
Expected Total Enrollment:  350

Study start: March 2001

The brain imaging is conducted at the Institute for Neurodegenerative Disorders in New Haven, Connecticut. The imaging procedure occurs over a two day period.

On the first day participants are injected with [123I]ß CIT, an investigational radioactive material that localizes in the brain. Study participants will also have a thorough neurologic examination and standard neuropsychological testing, including testing of memory, concentration, abstraction and visual spatial functions.

Twenty-four hours later study participants return to the Institute for Neurodegenerative Disorders where an investigational scanning procedure will be used to obtain SPECT (single photon emission computed tomography) images of the brain.

Participants may be contacted to repeat these procedures every 12 to 18 months.
