Tremor in a Bassoonist: Tremor in Dystonia or Essential Tremor?
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...
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 کاملTremor-correlated cortical activity in essential tremor.
BACKGROUND In patients with parkinsonian resting tremor, tremor-correlated activity in the contralateral sensorimotor cortex has been studied by both magnetoencephalography (MEG) and electroencephalography (EEG). In essential tremor, MEG failed to detect cortical involvement. The objective of this study was to investigate whether EEG recording can reveal tremor-correlated cortical activity in p...
متن کاملEssential tremor
Methods Seventy-two patients with severe, medication-refractory essential tremor have been enrolled across seven international centers. Standard assessments of tremor severity and disability will be obtained before and after the procedure. Patients are randomized in a one-to-three fashion to receive either sham procedure or MR-guided focused ultrasound thalamotomy. The Tremor Research Group, ne...
متن کاملAgnosia for head tremor in essential tremor: prevalence and clinical correlates
BACKGROUND Lack of awareness of involuntary movements is a curious phenomenon in patients with certain movement disorders. An interesting anecdotal observation is that patients with essential tremor (ET) often seem unaware of their own head tremor. In the current study, we asked ET patients whether they were aware of head tremor while it was occurring on examination, thereby allowing us to gaug...
