Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that primarily affects motor neurons in the brain and spinal cord. As these motor neurons degenerate and die, the brain loses the ability to initiate and control muscle movement, leading to symptoms such as muscle weakness, atrophy, and paralysis. Eventually, ALS can impact essential functions like breathing and swallowing, while cognitive functions often remain intact. The exact cause of ALS is still largely unknown, and there is currently no cure for the disease.
