WebAbstract. Parkinson's disease (PD) and Dementia with Lewy Bodies (DLB) are both neurodegenerative diseases characterized by the abnormal intraneuronal accumulation of misfolded α-Synuclein into Lewy bodies and Lewy neurites. They are distinguished in part by the temporal relationship between the onset of parkinsonism versus cognitive signs ... WebLewy body diseases, and dopamine is reduced in the basal ganglia as a consequence of the aggregation of Lewy bodies in this area of the brain (3,4). Imaging of the dopamine transporter (DAT) with SPECT serves as a surrogate marker of the nerve connection between axons from the substantia nigra and neurons in the striatum (5,6). An in vitro
