I too had brain swelling.
I would fall to the floor.
I had severe neural issues.
When I took Iodine, the problem became much worse.
I figured out it (brain swelling) was being caused by liver toxins, and parasites in the brain stem.
I had bacterial, and fungal gut infections, in addition to parasites.
Later on I lost circulation in the limbs, and the lungs filled up with fluid, the pulse went to 200.
I would start with 2 weeks of deoxycycline, scan for SIBO and SIYO using herbal kind of things. The current release of my document, and earlier CZ posts detail some of these herbs.
I tried crates of herbal parasite cures. None touched my infection. I assume worms have grown up since the early days, and herbs just cannot reach them.
I even failed at anti-parasitic things. It seamed as I was destined to die. Then I retraced my steps and came across 2 papers, one suggested high dose albendazole, the other suggested combining praziquantel with albendazole for rare infections.
After my hair fell out from albendazole, I started to dump flukes. To make a long story short, Flukes caused my brain infection. Once the flukes were gone, the Ascaris worms died. I now seam to be parasite free some 61 days after combining the two.
8 years of hell, and finally, hopefully just in time, I have some life back. My kidneys and liver are not to pretty, my memory bad, but I am still alive. No thanks to the doctors.
