Dr. Lagos, a pediatric neurologist and professor, has written the first non-technical book within memory on that stigmatized condition which is not a disease but a symptom with many causes and of many types. It is common in children, almost always controllable (phenobarbital, Dilantin), rarely hindering the development or intellect of the child. This, question and answer course of instruction should be highly reassuring for the four million classified as epileptics -- with as many more experiencing occasional convulsions. From origins (birth trauma, vitamin deficiency, etc.) to diagnostic tests to the available treatments -- Dr. Lagos should benefit all those parents with their handed-down fears of the grand mal, or petit, who will learn how to handle their child at home and bring him up in a normal fashion to lead -- in almost all cases -- a normal life. The book is a model of differentiation and clarity.
