I think it is ridiculous when people claim that neurological problems are untreatable. they are on the whole no less untreatable than psychiatric disorders, and the rare degenerative disorders are just that, rare. psychiatry shares some of these neurodegenerative disorders (dementias) with our neurology colleagues. epilepsy and migraine - which are are amongst the most common - are eminently treatable. MS and parkinson's disease are about as treatable as chronic schizophrenia or severe bipolar disorder. Most conditions in medicine are not curable, and many are fatal or terminal. For the right person, there is nothing more rewarding that managing those problems for which we have no cure, or for which relief of symptoms is sub-optimal.
Neurologists are not largely dissatisfied with the field because it is boring (the brain has the widest range of possible diseases of any organ), nor because of poor renumeration (they do on average make significantly more than psychiatrists). It is because the kind of person who often goes into neurology is interested more in disease than in patients, only to find that most of what they are seeing is psychiatric (headaches, fatigue, vague weakness, chronic pain, non-epileptic attacks, depression, anxiety, personality disorder, conversion disorder) that they have no interest in dealing with.
This is 100% true. Clinically, neurology can be the most intellectually demanding, yet satisfying discipline in medicine. The neurological exam is the most difficult of all of the physical exams in medicine, takes years to learn how to do accurately and consistently, and is still very much relevant. I am loving my neuro rotations as a resident- seeing both the classic pathologies as well as the zebras- and the finesse with which the experienced attendings diagnose at bedside is just incredible. Being at a huge academic medical center with one of the nation's premier neuro departments has definitely provided me with an unforgettable experience. I agree with Splik- neurologists get disgruntled when they step away from academia and enter private practice, where they have to deal with the "uninteresting" conditions Splik mentioned- and they have to see a TON of patients to keep up RVUs. The ones who stay in academia, however, seem very satisfied and never want to retire.
I really hope that I am alive to see a revolution in psychiatry where we can be as sophisticated as neurologists in our diagnostic methods- meaning it takes an actual MD using skill sets from years of basic science, clinical science, and residency to truly be able to reliably and accurately diagnose pathology. DSM III was a great step forward in terms of reliability, but now, as anyone who has ever worked in an inpatient psychiatry knows, now with operational, disjunctive criteria, everyone who works on the unit- nurses, techs, SWs, etc etc etc think that they are the diagnosticians. And to some extent, it's true- our diagnostic methods are taught to every mental health professional, essentially qualifying them as diagnosticians (at least in their minds).
Relating to that last point, because of its deeply intellectual and difficult nature, neurology is one of the fields most protected from midlevel encroachment, which is definitely a good thing. The neuro department at my institution hired a few NPs, but they are largely confined to clerical roles. I have personally seen a neuro NP completely miss pseudohyponatremia and different neuro NP have no clue what a Wallenberg is. Seriously, Hughlings Jackson, Paul Broca, Carl Wernicke, Jean-Martin Charcot, Pierre Marie, Norm Geschwind etc would be absolutely irate that people so unqualified are allowed to "practice" neurology!
In any case, psychiatry is intimately linked with neurology, without question moreso than any other field, and for the advancement of our field, neurology is absolutely invaluable.
