Abstract
The effects of aging on brain dopamine transporters was evaluated in 2 6 healthy male volunteers (age range, 21-63 years) using positron emis sion tomography and [C-11]cocaine. The ratio of the distribution volum e for [C-11]cocaine in basal ganglia to that in cerebellum was used as a model parameter for dopamine transporter availability and showed a significant negative correlation with age (r = 0.65, p < 0.0005). This results document an age-related decline in dopamine transporters in h ealthy individuals.
