Using SPECT imaging of the Dopamine transporter, van Dyck’s work has shown that there is loss of dopamine from the aging striatum, and that this is related to a slowing of reaction time, a measure of mental chronometry. van Dyck uses PET imaging to track Alzheimer’s-related pathology, to learn how pathology relates to ApoEApoE genotype, and whether it is diminished by potential treatments. Dr. van Dyck has collaborated with Dr. Richard Carson at the Yale PET Center to test the new PET ligand 11C-UCB-J, which binds to SV2A to provide an assay of presynaptic axon terminals in the human
