You can go to YouTube and watch a surgeon remove a living liver fluke from a liver. You can watch worms crawling inside an intestine. There are heartworms and larvae that migrate into the lungs and brains.
I am fairly certain that I had flukes clogging my bile ducts. Once killed, my digestion improved and my appetite changed. I passed Gallstones painlessly. I passed multiple cholesterol stones painlessly.
It is known that parasites cause a lot of symptoms. Google Dr. Andreas Kalcker. He has a free 18 page pdf on parasites that has pages of symptoms.
There are some parasites that can travel into the brain and cause seizures. It's common in So and Central America. There are parasites that cause blindness and severe swelling of extremities. Common worms can live in the eyes and can be expelled from the mouth and nose.
Parasites can create a biofilm to hide from our immune system. In an effective parasite cleanse, you have to destroy that biofilm.
Parasites have preferences for carbs, sugar, iron and B12. They can create cravings in their host for the same. It's best not to feed them.
There are so many parasites and so much that we don't know about them. They can adapt to drugs and run from treatments.
How many nightmares do you want? How much paranoia? How phobic do you want to get?
Keep reading this forum.

No its not easy for parasite to get to your brain. The body only defense is white blood cells and increase body temperature.


Don't have much defense for worms. But yes they can control you Candia does by giving you intense Sugar cravings.

It is quite possible for infections to reach the CNS but the effects are largely due to systemic involvement in infections. For instance cytokines are powerful immune factors that are produced when infection hits the body, they pass through the blood brain barrier and enter the CNS where they inhibit normal brain function. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2136407/

Pathogens create a large amount of oxidative stress which overloads the body's detoxification functions, for instance the liver becomes overloaded and toxins are backed up. Cell membranes are attacked by the oxidative stress and can no longer operate at normal functioning. When cell membranes are attacked then cells don't behave as they should. Remember there are many types of cells that all perform certain functions (neurotransmitters, hepatic cells and so on).

Strong immune reactions cause endocrine shifting which further limits the body to function correctly. Adrenals become taxed and can no longer function to produce vital hormones and the whole cycle continues.

This is why it is necessary to support the body with nutritional intervention to stop the degradation and in the meantime to use effective strategies to eliminate pathogens and the co-infections.

I'm not sure about all the answers to this, but the myelin sheath can get destroyed and plaques can form in the brain that they call MS or ALS. The body has to be cleaned out by colon cleansing and Liver Flushing that will allow the whole body to clean itself out. Wheat germ oil is good for rebuilding the myelin sheaths.

parasites poison the body with their waste products and can cause alteration in ability to absorb nutrition and probably use it to advantage. Fungus can alter brain function and is responsible for panic attacks. From what I've read it eats holes in the blood brain barrier and the brain gets the acetaldehyde from the metabolism of yeast fungi. Been there and done it.
