How does a neurologist differ from a psychiatrist?

Different specialty: Both are physicians graduating from medical school and 4 years of residency. There's some crossover in conditions like dementia, but focus & training differs. Neurologists deal with disorders of the central and peripheral nervous system -- focus on anatomy and nerve pathways. Psychiatrists deal more with brain processes, chemistry, and emotional disorders. Oversimplified, absolutely. :-).

Different Brain MDs: Neurologists (n) and psychiatrists (p) both treat brain illnesses, just different types. N: brain illnesses relating to movement, memory, infection, stroke, tumor, vascular, nerve conduction illness. (p): brain illnesses relating to thinking, mood, anxiety, behavior, including any impairment in eating, thinking, functioning alone or with people. P and n provide meds. P trained in psychotherapy.
