To broadly sample ET in different settings, we selected cases from three settings: a tertiaryreferral center (largest sample),5 a population-based study in Manhattan,6 and a brain repository.7 As expected, cases differed in several respects (Table). Using the same clinical questionnaire, each case was asked whether he/she sometimes has a head tremor. A 20 minute videotaped tremor examination wa...
Genetic polymorphisms in Solute carrier family 1 (glial high affinity glutamate transporter), member 2 (SLC1A2) have been linked with essential tremor. SLC1A2 encodes excitatory amino acid transporter type 2 (EAAT2), which clears glutamate from the synaptic cleft. One postulated mechanism for essential tremor is the over-excitation of glutamatergic olivo-cerebellar climbing fibers, leading to e...
Six patients with essential tremor tested in the therapeutic effectiveness of a 6-carbon alcohol, methylpentynol, 200 mg/day, against placebo in a randomised double-blind clinical cross-over trial. The effect of methylpentynol on postural tremor amplitude was not different from that of placebo.
Using a computer-controlled torque motor and manipulandum, 50 ms torque pulses and 70 second trains of binary pseudorandom torque disturbances were applied to the wrists of 10 adult controls and 22 patients with essential tremor in order to study the interaction between mechanically-induced stretch-reflex oscillations and essential tremor. These two oscillations were separated by applying inert...
BACKGROUND The re-emergent tremor of Parkinson's disease (PD) is generally recognized as a postural tremor. PHENOMENOLOGY SHOWN A PD patient with a re-emergent tremor occurring during a task (spiral drawing), which on the surface produced a tremor that resembled that of essential tremor (ET). EDUCATIONAL VALUE Researchers and clinicians should be aware of features of this re-emergent tremor...
High frequency deep brain stimulation of the thalamus can help ameliorate severe essential tremor. Here we explore how the efficacy, efficiency and selectivity of thalamic deep brain stimulation might be improved in this condition. We started from the hypothesis that the effects of electrical stimulation on essential tremor may be phase dependent, and that, in particular, there are tremor phase...
