Thanks for your post, Yes I suppose it is possible in theory, but as in the first phase described in the article, surviving motor units are taking in charge junctions of the dying motor units, so the disease is invisible. There are many theories about what causes ALS, most are borrowed from other diseases and some may reflect our thinking processes: We need a single cause for our comfort. But there may be no single cause of ALS, and perhaps no causal chain at all. Actually it could be simply that when an upper motor neuron is stressed the disease is named ALS, when it is a neuron in substancia nigra it is called Parkinson, and when it is in the cingulate gyrus (and mostly in lobes) we call it Alzheimer. But actually it is a story about neurons that are dying in the brain.
