Thanks for that. I researched Cu ATSM and found this article
http://www.jbc.org/content/286/51/44035.full. It's very interesting but I note they didn't do any other health studies, that is, side effects and that the mice were killed before any long term effect could be noted.
My GP recently wrote a letter to the Government stating that I had less than 24 months to live due to Neuro degeneration so at this point in time I have nothing to lose by trying alternative treatments.
I have an appointment to see a neurologist in September so I'll ask him to check out this research and see if he recommends some treatment.
In the meantime I've been started on a new tablet (an anti epileptic) to see if we can stop my ongoing episodes of partial blindness. Fingers crossed.
