Although we are sympathetic to Reynolds and Slocum's concerns, 1 their editorial errs on several points. The authors cite deference to regulatory (presumably Food and Drug Administration) approval as a constraint. The FDA has long recognized broad physician discretion in using FDAapproved drugs or d

β¦ Synopsis
In some cases, it is difficult to differentiate essential tremor (ET) from Parkinson's disease (PD), especially in the early stages of the disease. We investigated cardiac sympathetic dysfunction using (123)I-metaiodobenzylguanidine (MIBG) myocardial scintigraphy in 22 patients with ET, in comparison with early PD and tremor-dominant PD (TDPD). The mean ratio of (123)I-MIBG uptake in the region of interest in the heart to that in the mediastinum (H/M ratio) was significantly greater in patients with ET (1.99 +/- 0.21) than in those with either TDPD (1.28 +/- 0.11) or early PD (1.28 +/- 0.17; each P < 0.001). The H/M ratio in all patients with ET was greater than two standard deviations above the range of the ratio in the patients with early PD or TDPD.

We used transcranial magnetic stimulation in 10 patients with essential tremor and 8 matched healthy subjects. A round stimulating coil was placed over the vertex and electromyographic activity was recorded from the first dorsal interosseous muscle. Paired transcranial stimuli were delivered at inte
## Abstract Several studies have reported an increased risk to develop Parkinson's disease (PD) in essential tremor (ET) populations. Hyperechogenicity of the substantia nigra (SN) is a common transcranial sonography (TCS) finding in PD and has been suggested as a PD riskβmarker in nonparkinsonian
