Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that affects nerve cells in the brain and spinal cord. ALS causes muscle weakness, paralysis, and eventually leads to difficulty in breathing and swallowing. The exact cause of ALS is unknown, but it is thought to be a combination of genetic and environmental factors. Some potential risk factors include age, gender (men are slightly more likely to develop ALS than women), family history, and exposure to certain toxins. There is currently no cure for ALS, but treatments can help manage symptoms and improve quality of life.
