PSYCHIATRY: Principles, Diagnosis, Clinical Practice and Decision-Making

Psychiatric symptoms rarely arrive in neat diagnostic categories.Depression may conceal bipolar disorder. Hallucinations may arise from psychosis, substance exposure, delirium, neurological disease, or a medical condition. Agitation may represent mania, intoxication, withdrawal, fear, cognitive impairment, or an immediate emergency.Psychiatry: Principles, Diagnosis, Clinical Practice and Decision-Making teaches readers how to approach that complexity with structured clinical reasoning.This comprehensive 500+ page textbook connects psychiatric knowledge with the decisions clinicians and trainees must make: What syndrome is present? What dangerous condition must be excluded? Which diagnosis best explains the presentation? What treatment, disposition, monitoring, and follow-up are appropriate?
