This book is addressed to the general public, to report an important breakthrough in medicine and psychiatry. Working with other scientists, the authors have established that Schizophrenia is basically a physical illness caused by disturbances in the biochemical balance of the body, and that this is determined by genetic disposition. Evidence has accumulated that Schizophrenia may be due to a defective adrenal metabolism which results in production of a subtle poison in the blood of its victims. In varying degree, from mild to shattering, this Schizophrenic toxin interferes with normal brain function and creates bizarre disturbances and changes in perception, mood, and thought. Drs. Hoffer and Osmond have discovered a new therapy for Schizophrenia which relies on a single, harmless, and highly effective vitamin-- Vitamin B-3, also known as Niacin, Nicotine Acid or Nicotinamide. Massive doses-- 3,000 Milligrams per day, or several hundred times the normal dietary requirement-- successfully counteract the Schizophrenic Toxin. This powerful and safe vitamin is also useful in treating depression, children with learning disorders and for many cases of senility. In clear, simple language, the noted doctors cut through the confussion, misconception and myths that have surrounded Schizophrenia, obscuring its reality and compounding its tragedies. This book will be a godsend to many victims of this dread disease and their families.
