To the Editor: The editorial by Stuart C. Yudofsky, M.D., and Robert E. Hales, M.D. (1), was thoughtful and addressed a large conceptual issue in psychiatry. However, I am less sanguine about the rapprochement between neurology and psychiatry and their subsequent unification in neuropsychiatry. Psychiatry is the only medical specialty that concerns itself with the patient’s subjective world and labors at the uncomfortable interface between mind and brain, attempting to straddle both. As frustrating as the results of the effort sometimes become, it is at the core of our professional identity.
