ALS is a neurodegenerative disease that affects nerve cells in the brain and spinal cord. It is a complex disease that requires a multidisciplinary approach to diagnosis, treatment, and care. Many people choose to study ALS to understand its underlying mechanisms, develop new therapies, and improve the quality of life for those affected by the disease. Additionally, studying ALS can provide insights into other neurodegenerative diseases such as Alzheimer's and Parkinson's.
