[Postural tremor as first symptom of Huntington disease].
BACKGROUND
Initial manifestations of Huntington's disease (HD) are varied and chorea is not always the first motor symptom.


METHODS
We report the case of a 44-year-old woman, with a family history of HD, who presented isolated head and upper limbs tremor for 4 years. Genetic testing confirmed the diagnosis of HD and no cause of secondary postural tremor was found. Propanolol was introduced with success.


CONCLUSIONS
This kind of presentation is unusual and has mostly been reported in the juvenile form of HD.
