The prevalence and economic impact of chronic neurologic disease have increased dramatically over the past 50 years, as has the need for accurate, evidence-based measurement of disease progression and improvement. Neurologic rating scales are now used in both clinical trials and in practice to help improve efficiency, decrease costs, better monitor disease course, and direct appropriate therapy. In this extensively updated second edition, you will find new scales for pediatric neurology and rehabilitation, peripheral neuropathy and pain, HIV/AIDS, and more. Frequently used scales for such common conditions as stroke, Parkinson's disease, dementia, and multiple sclerosis have also been updated. The entry for each scale consists of: * A detailed description of original purpose and current use * Information on validation and administration * Actual reproductions of selected scales * Advantages and disadvantages of each scale * Key references to the literature
