This video from Nature Video discusses the neurons behind amyotrophic lateral sclerosis (ALS). The narrator explains that ALS is a neurodegenerative disease that usually begins in adulthood and progresses rapidly.
The disease is characterized by the loss of both upper and lower motor neurons, leading to muscle deterioration and the inability to move, eat and breathe.
In most cases, there’s no known cause of the disease and there’s currently no cure or effective treatment. The disease begins when errors in the systems that build up and break down cellular proteins set off a chain reaction that eventually leads to a mutation of DNA. Further research is required for scientists to figure out which process causes the death of motor neurons so they can try to halt that process, slowing down or reversing the effects of the disease.
