Juli Bollinger, M.S.

Huntington’s Disease

Huntington’s disease is a fatal neurodegenerative disease characterized by uncoordinated and uncontrollable movements, cognitive deterioration and behavioral and/or psychological problems. Symptoms usually appear between the ages of 30 to 50, and worsen over a 10 to 25-year period until the patient eventually dies. Chorea is the pronounced symptom of the condition. Children of Huntington's disease parents know that they have a 50-50 chance of getting the disease and many are relunctant to take the genetic test prior to symptoms appearing.
