Individual cases of HD vary in terms of the symptoms present. People affected with HD may at first notice personality changes, depression and mood swings. Many experience impaired judgment and memory loss.
Physical symptoms accompany the mental changes.
Patients may appear clumsy or fidgety at first. As the disease progresses, stuttering and slurred speech become common. Eventually restless movements become exaggerated and incessant. Although each case varies in terms of the symptoms present in each sphere, all cases worsen over time. Death usually occurs an average of 16 years after onset due to complications of the disease or accidents and sometimes even suicide.
