By Mayo Clinic staffAfter onset of the disease, signs and symptoms continue until death. Though the signs and symptoms vary from person to person, vital functions, such as swallowing, eating, speaking and walking, usually degenerate over time. Depression is common in Huntington's disease, and some people are at risk of suicide. However, death generally occurs as a result of complications of the disease, such as a fall or an infection like pneumonia.
