Neurological features in celiac disease (CD) are not rare (5%-36%), but tremor is scarcely described. Subjects with CD and healthy controls completed an online survey using WHIGET tremor rating scale. One thousand five hundred and twelve subjects completed the survey, finally 674 CD patients and 290 healthy subjects were included. A higher prevalence of tremor in CD patients was observed in com...

Tremor amplitude was monitored in untreated patients with essential tremor by a procedure designed to minimise fluctuations due to factors known to influence tremor. Tremor was measured hourly for 6 hours in 14 patients and on five to seven occasions (separated by at least a week) in 22 patients. A wide range of within-patient variability was found, with some patients showing little and others ...

PURPOSE To examine the long-term risk of essential tremor (ET) in migraine. METHODS Using population-based administrative data from a subset of the National Health Insurance Research Database (NHIRD) of Taiwan, we identified 22,696 newly diagnosed migraineurs (mean age 44.5 years) and a matched migraine-free cohort of 90,784 individuals in the period 2000-2008. Multivariable Cox proportional ...

JMD Dear Editor, Tremor is a common clinical feature in dystonia. It can be seen in both affected and unaffected body parts in patients with dystonia. Clinically, it may not be easily distinguishable from essential tremor, currently defined as a bilateral, largely symmetric postural or kinetic tremor involving the hands and forearms that is visible and persistent, with an associated or isolated...

Essential tremor (ET) still remains a clinical diagnosis. Nonetheless, it is misdiagnosed in 30 to 50% of cases. There are a number of areas of diagnostic uncertainty. One of these is isolated head tremor, on which published data are limited and at variance. We studied the prevalence of isolated head (i.e., neck) tremor in ET in two population-based studies (Turkey and New York) and a large cli...

We reported the case of a 74-year-old woman suffering from essential tremor for 20 years which was treated effectively with purified bovine brain gangliosides containing GM1, GD1a, GD1b and GT1b gangliosides. The trials of the treatment were conducted twice, 40 mg and 20 mg gangliosides per day respectively administered intramuscularly. Essential tremor dramatically improved with gangliosides o...

Practolol, propranolol, and placebo have been tested on an objective test of lithium induced tremor. Both beta-blocking agents produced significantly more tremor than the placebo. It is argued that lithium induced tremor is closer to essential than to physiological tremor.

The relationship between plasma propranolol concentration and relief of essential tremor was examined in 11 patients during treatment with oral racemic propranolol in doses of 30 to 640 mg/day. Although propranolol decreased tremor in all 11 patients, the degree of improvement varied widely in individuals (mean 51%, range 25--90%), and was not related directly occurred at plasma propranolol con...

Estimating the functional topology of a network from multivariate observations is an important task in nonlinear dynamics. We introduce the nonparametric partial directed coherence that allows disentanglement of direct and indirect connections and their directions. We illustrate the performance of the nonparametric partial directed coherence by means of a simulation with data from synchronized ...

The neuronal physiological correlates of clinical heterogeneity in human essential tremor are unknown. We now test the hypothesis that thalamic neuronal and EMG activities during intention essential tremor are similar to those of the intention tremor which is characteristic of cerebellar lesions. Thalamic neuronal firing was studied in a cerebellar relay nucleus (ventral intermediate, Vim) and ...
