Those diagnosed with ALS experience difficulty moving and speaking and, as the condition worsens, difficulty swallowing and breathing. Beyond this definition, however, what do those affected by ALS need to know?What You Need to Know about ALS is a part of Greenwood's Inside Diseases and Disorders series.

The text follows a standardized structure, with each chapter exploring a particular facet of the topic. In addition to covering causes, signs and symptoms, diagnosis, and treatment options, books in this series delve into issues that are less commonly addressed but still critical to understand, such as effects on loved ones and caregivers. Case illustrations highlight key themes discussed in the book and are accompanied by insightful analyses and recommendations.
