Spontaneous blinking in humans is mediated by the central dopaminergic activity and can be a useful clinical sign. The blink rate is decreased in diseases of altered dopaminergic activity like Parkinson’s disease and increased in Huntington’s disease (HD), Tourette’s syndrome, and Wilson’s disease. Blepharoclonus is a rare abnormal movement of the eyelids where repetitive spasms of the lid on gentle eye closure of the eyes are seen. We present a case of Juvenile Huntington’s Disease (JHD) with a rare combination of excessive eye blinking and blepharoclonus.
