Most ALS is not genetic, and im not sure about parkinsons, but I suspect it's similar. Lots of studies these days are finding links between viruses that dont actively cause much harm when you are infected, but and up being highly associated with autoimmune diseases. A prime example is Epstein-barr virus and MS. I have no clue what the mechanisms are, and im sure scientists are still learning, but basically an infection could cause an immune response that is too strong, and even after the infection is gone, the response remains.
