Tremor-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 کاملCortical involvement in the generation of essential tremor.
Conflicting results on the existence of tremor-related cortical activity in essential tremor (ET) have raised questions on the role of the cortex in tremor generation. Here we attempt to address these issues. We recorded 64 channel surface EEGs and EMGs from forearm muscles in 15 patients with definite ET. EEG and EMG power spectra, relative power of the rhythmic EMG activity, relative EEG powe...
متن کاملTremor 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 کاملThe timing of tremor: a biological clock in essential tremor?
patients who were older than 60 (tremor duration ≥ 10 years). The difference was highly significant. In multivariate models, while head tremor was associated with age (p < 0.001), it was not independently associated with tremor duration (p = 0.26). Indeed, with the exception of 1 patient, head tremor did not begin before age 36. In sum, these data, from a large sample of ET patients, indicate t...
