What are the essential differences between neurology and the other fields of medicine?

The differences between Neurology and other fields of medicine are dependent usually on the system you are wanting to work within. A Diabetic Educator for instance works in the Gastrointestinal Unit at the hospital or similar employer. Even Neurology has subcategories of physicians. Speech Therapy is a good example to use for the Neurology field. Your school may or may not have a Speech Therapist on staff. If so you may have the ability to ask your Guidance Counselor if they would arrange an interview or meeting. Networking is a large part of adult life and getting to know someone who does what you want to do is always a blessing.
