You usually start by seeing your GP. They will ask you about your general health and symptoms and will also examine you. Your doctor will then decide whether to do tests or refer you to a specialist. Some people have symptoms that come on quite suddenly such as a severe headache and drowsiness or a fit (seizure) and need to go straight to an Accident and Emergency (A&E) department.
