Diagnoses and treats mental illness through medication and therapy, one of medicine's only specialties with legal authority to detain a patient in crisis. A psychiatrist is a physician who diagnoses and treats mental illness, licensed to prescribe medication and, in most countries, one of the few professionals with legal authority to detain a patient against their will for safety. That distinguishes the role from a psychologist, who holds a doctorate in psychology rather than medicine and in most places cannot prescribe, and from a general therapist or counselor, whose training is shorter and narrower. A psychiatrist's toolkit spans medication, talk therapy, and, in severe cases, procedures like electroconvulsive therapy — reasoning across biology and biography at once.

The profession's authority once rested on custody, not cure: for centuries the mentally ill were confined in asylums by keepers with little ability to treat what they observed. Philippe Pinel's removal of chains at Paris's Bicêtre in 1793, Emil Kraepelin's turn-of-the-century classification of psychosis, and the 1952 arrival of chlorpromazine — the first drug that reliably calmed psychotic symptoms — each pushed the job further from custodian toward physician. The DSM's 1980 shift to checklist-based diagnosis then remade how psychiatrists talk to each other about what they're treating at all.

Today the job splits sharply by country: some psychiatrists spend most of a session prescribing and monitoring medication in fifteen-minute slots, others still deliver an hour of talk therapy themselves. Global demand is rising faster than training pipelines can fill it, telepsychiatry has made rural and cross-border care routine, and ketamine- and psilocybin-based treatments are re-entering serious clinical trials after a half-century of prohibition. Nothing about the underlying task — reasoning about a mind through incomplete, self-reported evidence — is easy to hand to software, but the paperwork increasingly is.
