Huntington's Disease Diagnosis
Because many of these symptoms can be caused by other diseases, a detailed physical and neurological examination is usually needed. Not surprisingly, a family history of the disorder is often the biggest clue that you may have Huntington’s disease.
Special blood tests can help doctors determine your likelihood of developing Huntington’s disease. A CT scan of the head can evaluate the scope and scale of brain cell damage and loss of brain tissue. An MRI scan or a PET scan may also be used.
