Amyotrophic lateral sclerosis or more commonly known as ALS is a progressive neurodegenerative disease. It is characterized by the death of motor neuron cells in the cerebral cortex, brain stem and spinal cord and is accompanied by loss of muscle control, which eventually leads to complete paralysis (Suzuki and Svendsen, 2008). This paralysis causes death due to respiratory failure within 3-5 years after diagnosis.
