Unusual Forehead Tremor in Four Patients with Essential Tremor
Forehead tremor has only been reported in two patients with essential tremor, one with rhythmic tremor and the other with dystonic tremor. We report 4 new patients with essential tremor who present a 4-6 Hz frontal tremor registered by electromyography and unusual features like frontal tremor preceding limb tremor or unilateral involvement. Frontal tremor is present in some patients with essent...
متن کاملUnawareness of head tremor in essential tremor: a study of three samples of essential tremor patients.
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...
متن کاملGABAergic dysfunction in essential tremor: an 11C-flumazenil PET study.
UNLABELLED Essential tremor is the most common movement disorder, but the underlying pathophysiology is not well understood. A primary overactivity of cerebellothalamic output pathways is the most conspicuous finding, as indicated by animal and human studies. It has been argued that this overactivity may be due to impaired central inhibition, and converging evidence points toward a potential ro...
متن کاملInfluence of alcohol on gait in patients with essential tremor.
OBJECTIVE To study the effect of ethanol on gait in patients with essential tremor (ET). METHODS Using a three-dimensional opto-electronic gait analysis system, the authors analyzed gait at free-speed walking, at a given velocity, and during tandem gait. Patients with ET with advanced disease were examined before and after a small oral dose of ethanol. The results of the patients with ET were...
متن کاملDiffusion tensor imaging in patients with essential tremor.
BACKGROUND AND PURPOSE The traditional paradigm has regarded essential tremor (ET) as a benign disorder. However, recent clinical, neuroimaging, and neuropathologic studies suggest that ET may be a progressive neurologic disorder. Based on clinicopathologic findings that cerebellum and its outflow are the key structures in ET and degeneration of gray matter in cerebellum is followed by conseque...
