According to Wikipedia, Amyotrophic lateral sclerosis, also known as motor neuron disease is a disease that causes the death of neurons controlling voluntary muscles. ALS is characterized by stiff muscles, muscle twitching, and gradually worsening weakness due to muscles decreasing in size. Most patients with ALS eventually lose the ability to walk, use their hands, speak, swallow, and breathe. There is no cure for ALS is known but the goal of treatment is to improve symptoms.
The cause of ALS is not known in 90% to 95% of cases, but is believed to involve both genetic and environmental factors. The remaining 5–10% of cases are inherited from a person’s parents. I narrowed the topic to write a literature review on research looking for the causes of ALS and how this motor neuron disease affects someone’s life. I hope to find the main causes of the disease and to have an insight on how someone with ALS lives day to day.
