Patient Series. Thirty-two parkinsonian patients (15 women, 17 men; mean age [±SD], 67
±7.4 y) were studied. All patients with Parkinson's disease who were admitted to or …

This study addressed whether cardiac sympathetic denervation progresses over time in
Parkinson's disease. In 9 patients without orthostatic hypotension, 6‐[18F] fluorodopamine …

We aimed to characterize the relationship between cardiac sympathetic and
parasympathetic dysfunction employing cardiac 123I-meta-iodobenzylguanidine (MIBG) …

In the last few years, cardiac sympathetic dysfunction in Parkinson disease (PD) has been
postulated on the basis of decreased cardiac uptake of sympathoneural imaging tracers …

Methods: We studied35 patientswith Parkinson'sdisease and 24 control subjects with other
central nervous system diseases. The latter group consisted of 12 subjects with other …

Background: In Parkinson disease, orthostatic hypotension can result from L-dopa treatment
or from sympathetic neurocirculatory failure. The latter is detected by abnormal blood …

Attention has been drawn to cardiac sympathetic denervation in Parkinson's disease (PD)
based on clinical studies using [123I] metaiodobenzylguanidine scintigraphy; however, the …

The uptake of 6-18F-fluorodopamine by cardiac noradrenergic nerves enables visualization
of the sympathetic innervation of the left ventricular myocardium by PET. Patients with …

The study was undertaken to investigate by means of iodine-123-labelled
metaiodobenzylguanidine (MIBG) scintigraphy the peripheral sympathetic function in …

Patients with idiopathic Parkinson's disease (PD) have impaired sympathetically mediated
neurocirculatory innervation. Here we analyzed the correlation between cardiac 123I …
