An illustration showing the human nervous system highlighting motor neurons affected by ALS, revealing progressive muscle weakness and neurodegeneration.
Amyotrophic lateral sclerosis (ALS), widely known as Lou Gehrig’s disease, remains one of the most devastating neurodegenerative disorders of our time. It is a fatal condition that gradually destroys the motor neurons responsible for voluntary muscle movement.
These neurons, located in the brain and spinal cord, are essential for everyday actions such as walking, speaking, swallowing, and breathing. Once they begin to deteriorate, the body slowly loses its ability to function, leading to progressive weakness, muscle twitching, paralysis, and ultimately respiratory failure.
