ALS

Introduction

ALS stands for Amyotrophic Lateral Sclerosis, sometimes called Lou Gehrig's disease. It is a rapidly progressive and fatal neuromuscular disease that is characterized by degeneration of a select group of nerve cells and pathways (motor neurons) in the brain and spinal cord. This loss of motor neurons leads to progressive paralysis of the voluntary muscles.
