I'm about to start on Freddd's protocol pretty soon, and I was also considering having my mother try it too... but I didn't know if it was ok for older people to do it too? She's 78, and is in poor health... it's kind of a complicated story, but in a brief nutshell, she has Parkinson's Disease (but relatively mild), which, as a side note, I believe was caused by many decades of her having a large amount of dental toxicity in her mouth (amalgam fillings, several root canals, as well as some other stuff, like dissimilar metals in her mouth, metal bridges, and a couple infected teeth, etc). (I myself got extremely ill from amalgam mercury poisoning many years ago, and am still trying to recover right now... so genetically speaking, it seems quite likely to me that she also could have a genetic predisposition to getting ill from mercury, as well as other toxins) She got much worse right after she got a bad case of flu/pneumonia in December 2014 (almost 2 years ago now, at age 76). That was the first time she ever got pneumonia/flu, and it indicated to me that her immune system was now low. (My thought on it was that after many decades, the mercury and other toxins in her mouth might've finally significantly lowered her immune system, esp. in old age) Anyway, shortly after that, she went into a rapid and major decline... she lost 20 pounds, got extremely weak, fell for the first time, kind of developed "CFS" overnight, her back got much more stooped, and she had to start using a walker (previous to that, she could walk without one). She also, in the last year or so, has a chronic hacking cough, and the signs of a chronic "cold" (runny nose, some sneezing, etc), which to *me*, looks like signs of a chronic infection (that her now low immune system probably can't fight off). Since all this first happened (starting Dec. 2014), she has been in a pretty similar state up until now, but just a *tad* improved from that earlier time, due to, I think, just a lot of time passing from the initial acute illness, plus just continuing to try several health-promoting things, like frequent gentle exercise, good diet, etc. (We also finished up extracting all her infected teeth and all root canals, except there is now only one root canal left... we left that in for now b/c she needs that tooth for chewing) The reason why I was *considering* trying Freddd's protocol for methylation on her is b/c.. 1. on a recent blood test, her homocysteine level was elevated. (I think the range was from 1-14 or so, and hers was 17, I think), and 2. on a genetic blood test I did last year, called Counsyl, it said that I tested positive for the MTHFR genetic mutation. (So I figured if I have this, maybe she has it too, being that we're closely related?) Questions: 1) Does an elevated homocysteine level on a blood test (such as in her case) indicate impaired methylation? (and thus a potential candidate to try Freddd's protocol?) 2) If I tested positive for the MTHFR genetic mutation, does it seem likely that she has it also? Or does the MTHFR mutation not necessarily occur frequently in closely related relatives... and to be sure, maybe she should get tested herself first, before trying Freddd's protocol? 3) Can old people (and in relatively poor health), like her (age 78), also try Freddd's protocol? 4) Does anyone by chance have any thoughts/feedback as to perhaps why she had such a huge decline after her flu/pneumonia event in Dec. 2014, that I had just mentioned? Any and all feedback greatly appreciated!! Thanks!
