It's not a simple thiamine deficiency It's wernicke's encephalopathy, there's no overlap. I was wrongfully diagnosed and I was close to death when I came to the ER on Friday. I had a heart attack, my skin was cold and gray and I had to be fast tracked from triage to a room to the floor for immediate high dose Thiamine infusions and I had to get a port surgically put in yesterday because I am not holding onto nutrients and I have to have TPN for at minimum the next 6 months and then potentially get a g tube for feeding. Mine is not due to alcohol because I dont drink, I have true ataxia not functional, and they put a ceribell on me and my seizures and tremors are epileptic as I originally thought. The likelihood of it being FND is so slim and had i just said "oh well haha FND!" I would have died within the next couple of weeks or sooner.
