Amyotrophic Lateral Sclerosis (ALS) is a fatal disease resulting in muscle weakness, paralysis and ultimately death, often within 2-3 years of symptom onset. These symptoms arise due to the loss of motor neurons from the brain and spinal cord. Treatment options are limited and have little impact on halting progression of the disease. This research project is aimed at developing and characterising new models of ALS that can be used to investigate how motor neurons degenerate in people living with ALS.
