Norma, suggest that you contact your closest Neurologist and/or a movement center near you. If all else fails, call the California Neuroscience Institute at 805 988 7599 or better yet, you might try to reach them by email [log in to unmask] You can mention my name if you want. They are excellent and will give you an honest answer.
