This book provides a valuable guide to understanding idiopathic intracranial hypertension (IIH), which is a very complex and painful disease. It is a chronic, often disabling condition resulting in headaches, visual loss, and ringing in the ears. This condition was thought to be rare but is becoming much more common, especially as the population becomes more overweight. Patients with this condition often suffer from intractable headaches with poor quality of life. Very few physicians specialize in this condition, and as a result, there is almost no information or resources available to those trying to understand this condition. The text is designed to take very complex neurosurgical anatomy, principles, and treatments and reduce them down into simple principles. The book contains 12 chapters, each organized into distinct sections. All chapters also contain key points from those paragraphs to summarize useful take home messages. Written by an expert specializing in this debilitating condition, Idiopathic Intracranial Hypertension Explained serves as a valuable guide towards understanding and treating IIH. The ultimate goal is to empower patients and families with knowledge about the disease.
