Grade 4-7–Without becoming overly technical, the authors explain the causes, physiology, treatments, and complications associated with these conditions. The books are well organized, and each title opens with a case history of someone who suffers from the disease. Depression is especially useful for readers seeking up-to-date information, explaining that there are different types of depression, and that many are caused by a chemical imbalance. The text boxes in each book include lists of famous people who suffer from the diseases, explain what readers can do to help people with the conditions, and offer various warning signs. The photos are colorful and although most are merely decorative, some are startling, including the brain scans of a patient with Alzheimer's and one who suffers from depression.
