Description
Book SynopsisThis book provides the contemporary, caring guidance you need to diagnose and manage seizures in a young patient. Beginning with an overview of the classification of seizure syndromes, the authors take a practical approach to a common but complex clinical challenge.
Trade Review“In general, I think this book very sound. It would be an excellent introduction for neurology residents and a good review for general paediatric neurologists who feel a bit out of touch with current treatments for epilepsy.” (The Canadian Journal of Neurological Sciences, 1 September 2013)
“This is an exceptional read, unlike others in the way it addresses the treatment of children with epilepsy, rather than just the treatment of epilepsy.” (Doody’s, 2 August 2013)
