Abstract

Over the past ten years, dopaminergic imaging has become increasingly part of the assessment and diagnosis of dementia. There are numerous PET and SPECT ligands available that target different steps in the process of neurotransmission. Abnormalities in dopaminergic imaging measures are consistent features of dementia with Lewy bodies (DLB) and other parkinsonian syndromes, and can be used to facilitate diagnosis, particularly in distinguishing between DLB and Alzheimer's disease. This review summarizes present knowledge in this area and the implications for current and future clinical practice.
