Familial aggregation of cranial tremor in familial essential tremor.
BACKGROUND Essential tremor (ET) is often familial and phenotypic features may be shared within families. Cranial (neck, voice, and jaw) tremor is an important feature of ET. We examined whether cranial tremor aggregates in ET families, after controlling for other factors (age, tremor severity, and duration). METHODS Among ET probands and relatives enrolled in a genetic study at Columbia Univ...

متن کاملFamilial migraine with vertigo and essential tremor.
We report a family with dominantly inherited migraine headaches, episodic vertigo, and essential tremor. All symptoms improved with the use of acetazolamide. Linkage analysis ruled out linkage to markers on chromosome 19p, known to be linked to the genetic defect in families with the clinically similar syndromes of hemiplegic migraine and periodic ataxia. This genetic heterogeneity of migraine ...
متن کاملRelationship between blood harmane and harmine concentrations in familial essential tremor, sporadic essential tremor and controls.
INTRODUCTION Harmane, a potent tremor-producing β-carboline alkaloid, may play a role in the etiology of essential tremor (ET). Blood harmane concentrations are elevated in ET cases compared with controls yet the basis for this elevation remains unknown. Decreased metabolic conversion (harmane to harmine) is one possible explanation. Using a sample of >500 individuals, we hypothesized that defe...
متن کاملFamilial Aggregation of the Cerebellar Signs in Familial Essential Tremor
BACKGROUND Although the hallmark feature of essential tremor (ET) is kinetic tremor, patients may exhibit additional motor features (e.g., intention tremor and mild gait ataxia) that are markers of an underlying abnormality of cerebellar function. ET is also a highly familial disorder, but we do not know whether the presence and expression of cerebellar signs are similar across family members. ...
