My father has Huntington chorea and his body is stiffening up. I would like to know if this means he is going to pass away soon. His side of the family has had this disease. It has not skipped anyone yet. I was young and don't remember what happens. See answer
Resent test results showed 17 repeats from each parent. The social worker suggested that the test might be in error because the number of repeats is the same. Instead of telling the person they did not have HD, she suggested the test was in error. How likely or unlikely is it for the number of repeats to be the same? When one needs a definitive positive or negative, this negative result, being suggested as possibly an error, is heart wrenching, especially for the patient and her family. Is it uncommon for the numbers to be the same? Should she be retested? How common are mistakes in diagnosing HD? The patient lost a parent to HD. See answer
Can a person of any gender, age, or ethnicity have Huntington disease? See answer
I am a personal trainer working with a client who has HD. While I have seen progress with the exercises we are doing, I am looking for more information regarding the types of exercises that are found to be most effective or certain exercises that should be avoided. See answer
What tests will my doctor order to confirm if I have Huntington disease? See answer
A friend of mine has been diagnosed with Huntington disease. No one else in his family has this condition. Is it possible that a chemical exposure could have caused it, such as to vinyl chloride? See answer
I have a family history of Huntington's disease. My mother was diagnosed with it about 5 years ago. I just needed to know some information about where I can get tested. Also, how early can they start treatment if I am diagnosed with it? I'm only 21 years old. I just thought that maybe the sooner they start the better. See answer
