Q&A with Dr Marion Thank you all for your questions. We have put as many as we could to neurologist Dr Marie-Helene Marion and filmed our Q&A. In this discussion we focused on focal dystonias and botulininum toxin. Expand Thank you to all those who submitted questions - unfortunately due to time restraints we have been unable to ask all the questions and we have grouped some questions together. If you still have questions please do contact our Helpline on 020 7793 3650 or by emailing [email protected] So that you can find individual questions easily, we have included the timings for each question below: 0.00 - Introduction 0.58 - What causes dystonia in adults? Can any vaccines, peripheral nerve damage, the menopause, surgery have any affect? 6.18 - Does dystonia spread?
