... As mentioned in the pathophysiology section, there are a wide variety of triggers implicated in the motor neurone degeneration seen in ALS. The main two implicated currently implicated in ALS are: Oxidative damage – as a result of a mutant SOD1, superoxide radicals accumulate hence cause damage. Thi ...
