I deeply and sincerely hope that the lithium therapy does in fact stop further progression of the disease, or even slow it down. More power to the PALS for taking this informal study (the spreadsheet to track effects) into your own hands. There is not always time to wait for the slow process of formal scientific investigations, though these are also critical to confirm or refute the results of the Italian study. If my dad were still around, I would encourage him to try it, as there is just about nothing to lose. Also, lithium has been used as an effective drug for other illnesses for many years, and therefore doctors will have access to it and it is not so experimental as taking something that is not already approved for other uses.
