Final answer:
Amyotrophic lateral sclerosis (ALS) is a neurological disease that affects the motor neurons responsible for voluntary muscle movement. It leads to muscle weakening, lack of coordination, and ultimately paralysis. Special technologies have been developed to help ALS patients communicate.
Step-by-step explanation:
Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's Disease, is a neurological disease that affects the motor neurons responsible for voluntary muscle movement. The disease causes the degeneration of these motor neurons over time, leading to muscle weakening, lack of coordination, and eventually paralysis. ALS primarily affects the neurons that control speech, breathing, and swallowing, making patients rely on machines for communication and breathing assistance. Special technologies, such as brain-computer interfaces, have been developed to help patients with ALS communicate with the outside world.
