123I-MIBG myocardial scintigraphy and neurocirculatory abnormalities in patients with dementia with Lewy bodies and Alzheimer's disease

Our results suggest that MIBG scintigraphy and autonomic function tests may be useful for distinguishing between DLB and AD in clinical practice. Myocardial postganglionic sympathetic denervation and autonomic dysfunctions are present in patients with DLB regardless of spontaneous Parkinsonism.
