Often misunderstood and misdiagnosed, normal pressure hydrocephalus (NPH) is a disease of the elderly that is on the rise as the population ages. Its similarities to Parkinson's disease, dementia, and other chronic neurodegenerative conditions make diagnosis challenging, requiring clinicians to be alert to the signs and symptoms that differentiate it. Here is the first comprehensive book on the topic, written by experts who have researched and taught courses on NPH for years. From clinical characteristics and pathophysiology to signs and symptoms, radiographic findings, diagnostic tests, and state-of-the-art treatment techniques, it covers everything practitioners need to know about this multi-faceted condition. Special features include: - A description of the classic symptom triad of gait disturbance, urinary incontinence, and dementia - Coverage of the full sequence of the diagnostic work-up, including imaging.
