Email #1: Electrical Treatment for RP ()

First time long time listener (2010, I think). I'm a better thinker as a result of the show, so can't thank you enough. The book was great too. To my question: I have Retinitis pigmentosa (genetic degenerative vision condition). Diagnosed at 14 and now 36, so it's well on its way. Recently my partner found a German clinic advertising the Federov Treatment, link at the end. It claims not to cure but stabilize and, in some cases, improve night vision/peripheral vision. The treatment is electrical stimulation to retinal cells/optic nerve or parts of the brain dependent on the condition. It claims to natural - I don't see electricity to the dome in nature, myself - and the website is full of testimonials. I can't find anywhere else that delivers the treatment, although it's delivered by neurologists (good?) and has been going since '93. I've read a pinned review of the available studies, link at the end. Small studies in animals and humans...the improvements as far as I can see are all assumed markers: thicker this, increased blood flow to that, and the killer quote for me: "Despite several studies showing promising results in both animal experiments and clinical studies, there are presently few reports on the mechanisms of action for ES, making this field still poorly understood." I'd love to be wrong and not wait for CRISPR or the phase 2 stem cell trials, but I'm not optimistic. Thanks for all that you do; you're all wonderful. I don't know who picks these up, but I have to say that although she's part of the furniture now, I'm really happy with the addition of Cara. As much as I like the speculative and exciting potential sciences, I think she applies them to the world as it is: environmentally, socially, etc. I did have a COVID question, but this trumps it for me. Stay safe in these peculiar times and thanks again. - Stephen, Manchester, UK
