This book provides clear and concise guidance for clinicians when they encounter a patient with psychosis, starting with the medical work-up to arrive at a diagnosis and ending with the comprehensive care for patients with established schizophrenia.  It covers the optimal use of medications (emphasizing safe use) but also addresses other treatment approaches (psychological treatments, rehabilitation) and the larger societal context of care, including how to work effectively in complex systems. It uniquely condenses the literature into teaching points without simplifying too much, effectively serving as a learning tool for trainees and professionals.  For this second edition, the book was extensively updated and its content expanded, with new figures as well.  Each chapter begins with an initial summary and includes Tips and Key Points in text boxes.  Each chapter also includes links to external websites and additional readings.
