(after 50) there is probably plenty of time to become qualified and practice as a doctor before the onset of symptoms would prevent you from working as a doctor. You would also have time to pay off the university fees from the medical course. However if people in your family have had onset of HD in their 30s and 40s it might be important to consider whether it is worth putting all the years of study and the cost to only be able to practice as a doctor for 10 years or so. It might also be difficult to get ahead financially as you may have only just finished paying off the fees before you can no longer work as a doctor. These are difficult factors to weigh up as it is also important to pursue your dreams and you will be happier doing something you have always wanted to do. Having said that it is very difficult to get into a medical course. I assume you would be applying for a post graduate medical course, for which you have to sit an exam, which I understand is difficult to pass. It might be an idea to also look at other professions in which you could work in the medical field but not have to be a doctor eg physio, occupational or speech therapist, nurse, or medical researcher.
