Brief Summary:
The underlying goal of this study is to assess 123-I AV39 SPECT imaging as a tool to detect ß-amyloid deposition in the brain of AD research participants and age- and gender-matched healthy subjects
Detailed Description:
Approximately 20 patients with Alzheimers disease AD and 10 healthy controls will be recruited to participate in this study Healthy controls will be examined to ensure that there is no evidence of neurodegenerative changes including cognitive decline
All subjects will undergo written informed consent and a screening evaluation including baseline clinical laboratory testing a baseline physical and neurological evaluation and baseline cognitive evaluations
Subjects will be asked to undergo a bolus injection of 123-I AV39 Subjects will undergo serial SPECT imaging scans and serial venous plasma sampling for measurement of 123-I AV39 in plasma both protein bound and free over a period of up to 6 hours
Subjects may be asked to undergo a second imaging visit between 2 and 6 weeks following the initial imaging visit following similar procedures to the initial imaging visit to evaluate the reproducibility of the imaging measure using this procedure The imaging analyses will be performed by an image-processing specialist who will remain masked to the procedures employed with each imaging acquisition
The primary imaging outcome measure will be the brain regional distribution volumes expressed as a brain tissue to plasma ratio of the radioligand 123-I AV39 Time to the peak uptake and amplitude of the peak uptake will be evaluated for all brain regions and the results for the AD patients and controls will be compared
For those subjects undergoing repeat imaging visits the data from the initial scan will be compared to the second scan to determine which offers the reproducibility of the imaging outcome measure
