You may have already seen this fabulous news elsewhere, but I think it is so amazing I'm posting this Upworthy link, which shows the sheer wonder of it all very nicely.
This is the discovery that the lymphatic system does in fact connect with the brain. As someone with both potential autoimmune AND a neurological condition, this is hugely exciting information, and it does kind of underline the potential truth in all the gluten sensitivity theories for thyroid sufferers, but also, oh, so much more. It's so amazing, in fact, I hardly know where to start with thinking about the potential.
It's also great from the point of view of silencing depressing doctors who like to make fatalistic pronouncements about your condition. When talking about my Trigeminal Neuralgia once, my doctor announced "You will never know what caused it. You will never find a cure." At the time, aside from being deeply distressed at this nihilism, I was also furious that a so-called man of science could be so sure of this, given that we know hardly anything about anything. This discovery is living proof, if any were needed, that they discover new things all the time and NO-ONE, not even arrogant doctors with God complexes, can be sure of anything.
Keep up the hope - enjoy!
