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 undergo serial PET imaging scans and plasma sampling for measurement of \\[18F\\]-FMH3 in plasma (both protein bound and free) over a period of up to 8 hours. The primary imaging outcome measure will be the brain regional distribution volumes expressed as a brain tissue to plasma ratio of the radioligand, \\[18F\\]-FMH3.\n\nAt least 2 weeks following the initial imaging visit, subjects may be asked to return for a second injection and scanning procedure to evaluate the reproducibility of the imaging measure using this procedure.
