Just because you've been diagnosed with a neurological condition, don't rule out the possibility of travelling and seeing the world. Of course, you may have limitations in terms of where you travel, how you travel, where you go and what you do on your trip.
It's a good idea to see your GP and/or neurologist when you begin to plan your journey, and shortly before you go. They will be able to advise you of preparations and precautions and any special arrangements you might need to make for a safe and comfortable holiday.
Your travel plans will be guided by the nature of your disability and your mobility situation.
