"The Salts of the Earth and Synthetic Insanity" by Dennis Miller is a radically different view of the cause of Bipolar Mental Disorder. Author Dennis Miller uses physiology and biochemistry to explain this disease, also known as manic-depression. This book is unlike any other book on bipolar disease. Author Dennis Miller sets forth a physiologic explanation of the symptoms and cause of this disease. Author Dennis Miller proposes that the mental symptoms are a result of a physiologic disease that affects the kidney. Author Dennis Miller substantiates this theory with over 200 footnotes, many from the medical texts "Harrison's Principles of Internal Medicine" and "The Merck Manual," National Institute of Health, and major universities. If you have this disease or if you are involved in the treatment of this disease, then "The Salts of the Earth and Synthetic Insanity" is an absolute necessity.
