Neurology is a rapidly changing field right now, and the "lifestyle" is changing as well.
It's true... the acute treatment of stroke has now changed us from specialists who can usually say "Thank you for your call. I'll be in tomorrow morning" to the ER docs, to more like the cardiologists having to run in and deal.
That is not always the case, of course. Some centers are equipped to handle these eventualities without the attending coming in... for example, most academic centers have their residents supervise the tPA cases, and attendings are by phone. Also, some centers are starting "hospital neurologist" programs, much like the internist hospitalists... which, if you are into acute care neurology, can be quite fun and also lucrative.
It's a field in flux... in 20 years, it will resemble internal medicine in its subspecialties... sure, in 2005 any neurologist can do anything, much like in 1955 any internist could do anything.... In the near future, there will be recognized subspecialties, some of which exist now, such as clinical neurophys, stroke, neuromuscular... soon neuroimmunology, epilepsy, movement disorders, etc. The lifestyle will vary greatly based on the subspecialty...
As a clinical subspecialty that is now geared toward treatment, not just the diagnose and adios chinscratching of the previous generation, most neurologists are quite busy, and have a lifestyle similar to that of treatment oriented internists. Oh, mostly, we are still well paid if that's what ya wanna know lol.
