glad to hear you survived the black hole of surgery omores (whoever you are)
anywho, a few technical notes:
1.) you can apply directly to places for peds neuro as a senior medical student. you'd do your two years of peds at the same place as where you'd do pedi neuro. as you prolly know, there is no centralized application system (sucks); but the competition for pedi neuro spots is very different (b/c so few ppl end up going into it). of course, you can also apply as a peds intern and land a great spot (e.g. last year an intern at the middle of the road peds program at my school applied and landed a spot at Hopkins, this person wasn't a mud/phud or superstar)
2.) you might not have to do two years of peds. the ABPN (American Board of Psychiatry and Neurology) requires one of the following: a. two years of peds residency; b. an intern year of IM and an intern year of Peds; c. an intern year of peds and one year of basic neuroscience research. [Note: not all programs may accept b or c, depends on the PD and department. also, you may be able to swing just doing one year of peds if you're a MD/PhD and your research was in the basic neurosciences... that would have to be negotiated and approved before starting residency]

re bread and butter problems you'll see as a pedi neuro (listed by a great pedi neuro at my school): epilepsy, neuromuscular disease, cerebral palsy, ADD/ADHD, mental ******ation/developmental delay, CNS malignancy, neurogenetics.
it's a pretty broad spectrum, but as a general pedi neuro you can prolly expect >50% of your practice to be epilepsy. of course, if you subspecialize you'll skew your patient population (esp if you're at a big academic center w/ a strong pedi neuro presence)
also, adult neuro has a huge spectrum as well. during our medical school experiences (which are mostly inpatient) we're going to see inpatient problems, and thus many people think that adult neuro is mainly stroke, stroke, and more stroke.
part of the challenge is to know your personality and emotional strength. it takes a very special person to be able to deal w/ these innocent kids and their parents. i think kids are great, but i hate to see them sick and wouldn't be able to deal w/ so much suffering (esp as you'll see many of your patients die).
good luck on your decision. try to schedule as much elective time in adult and pedi neuro at your home and outside institutions, and see if you can't spend a good deal of time in clinics w/ a general adult neurologist and a general pedi neuro. remember that you will have a little pedi neuro training as an adult neuro resident (the minimum is 3 months, which is what all the programs that i applied to required; you could prolly use some of your elective time to do a pedi neuro elective if that floats your boat. BUT i doubt you'd be able to practice as both an adult and a pedi neuro).
