title: Auyana head nodders: essential heredo-familial tremor in the Eastern Highlands.
abstract: The syndrome of essential tremor occurs commonly in parts of the Eastern Highlands District. This description of the clinical features is bases on experience of over 200 patients and the influence of some pharmacological agents on the severity of the tremor are recounted. The age and sex incidence in several related linguistic groups is shown to be much greater than in neighbouring areas; so that the disorder can be epidemiologically defined within geographic and ethnic boundaries.
