Psychiatry is a branch of medicine concerned with the diagnosis, prevention and treatment of mental disorders. The assessment of a patient's condition usually begins with a case history and mental status examination. In order to obtain the case history of the patient, the psychiatrist asks the patient several questions. The answers to those questions aid the psychiatrist in the diagnosis and treatment process. A mental status examination is meant to assess a patient's mental state at a fixed point of time, by observing his appearance, attitude, speech, mood, behaviour and thought process. It is very useful in assessing a person's suicidal thoughts. This book unfolds the innovative aspects of psychiatry which will be crucial for the progress of this field in the future. It studies, analyzes and upholds the pillars of psychiatry and its utmost significance in modern times. Students, researchers, experts and all associated with psychiatry will benefit alike from this book.
