Juvenile Huntington’s disease (JHD) is mostly characterized by rigidity, myoclonus, bradykinesia, dystonia and seizure. We report a 9-year-old male JHD patient presenting excessive blinking as the initial symptom two years prior to typical JHD symptoms. Genetic analysis revealed expansion of 108 CAG repeats and magnetic resonance imaging showed caudate atrophy with lateral ventricular enlargement.
