Future research may show that there are many possible als causes. What causes als? viagra cost The cause or causes of als (amyotrophic lateral sclerosis) are not known, and scientists do not yet know why als strikes some people and not others.   als research scientists are looking at a number of possible als causes, including:   genetics glutamate autoimmune responses environment.   gene mutations an important step toward finding the causes of als came in 1993, when research scientists discovered that mutations in the gene that produces the superoxide dismutase 1 (sod1) enzyme were associated with some cases of familial als. buy viagra cheap   (click familial amyotrophic lateral sclerosis for more information about familial als. viagra 10mg duration )   the sod1 enzyme is a powerful antioxidant that protects the body from damage caused by free radicals. viagra mg 100 Free radicals are highly reactive molecules that are produced by cells during normal metabolism. buy viagra online pay with paypal If these free radicals are not neutralized, they can accumulate and cause random damage to the dna and proteins within cells. viagra vs viagra vs viagra reviews   although it is not yet clear how the sod1 gene mutation leads to motor neuron degeneration, researchers have theorized that an accumulation of free radicals may result from the faulty functioning of this gene. In support of this theory, animal studies have shown that motor neuron degeneration and deficits in motor function accompany the presence of the sod1 mutation.   causes of als article continues on next page > advertisement   als disease written by/reviewed by: arthur schoenstadt, md last reviewed by: arthur schoenstadt, md amyotrophic lateral sclerosis familial amyotrophic lateral sclerosis causes of als als symptoms als diagnosis treatment of als als research als and who it affects advertisement   referring pages: articles terms of use advertise with us contact us about emedtv privacy policy copyright © 2006-2012 clinaero, inc. generic viagra for sale in usa Emedtv serves only as an informational resource.
