Amyotrophic sclerosis is a disease of the nervous system that attacks nerve cells called neurons in the brain and spinal cord. These neurons transmit messages from the brain and spinal cord to voluntary muscles such as the arms and legs. Initially, this causes mild muscle problems
Amyotrophic lateral sclerosis (ALS) is the most common form of motor neurodegenerative disease. The disease with progressive destruction of motor neurons in the spinal cord, brainstem and motor cortex eventually leads to weakness and disability. Annual incidence 0.4-1 در 76 percent of the population. Disease spread is almost uniform worldwide. Men are almost twice as likely as women to be affected. The average life expectancy is 3-5 years.
The cause of the disease is still unknown. About 10% of cases of the disease are transmitted by family, one of the causes of which is a mutation in the superoxidase gene.

Diagnosis is based on a set of clinical signs and several paraclinical tests, with the advice of a neurologist.
So far, there is no definitive cure for this disease and only supportive therapies are prescribed to relieve the patient’s symptoms. The only specific drug made for this disease (Relutek (Riluzole)). Increases the person.
