This Figure is from Goldstein D.S., “Preclinical Catecholaminergic Biomarkers of Central Lewy Body Diseases,” J Clin Neurol2026;22:6-16. It shows two tri-phasic curves for loss of catecholamine stores in “body-first” central Lewy Body Diseases (LBDs)—loss of cardiac norepinephrine content via thoracic imaging and loss of putamen dopamine content via brain imaging.
