The brain is such an intricate system.

It is now believed that the amyloid plaques are a defense measure of the brain against the herpes virus. Experiments have shown virus infections leading to more deposits of amyloid beta proteins in the brain.
"We know about the devastating effects of Alzheimer's, but scientists still aren't certain about how it gets started. New research lends credence to an older idea, that bacteria and viruses could be contributing to the root causes of the brain disease.
In this latest study, the association has only been spotted in mice and petri dishes, but it's still a significant finding.
When infected with herpes viruses, previously linked to Alzheimer's, neurons in both the mice and the lab tests quickly developed amyloid beta (Aβ) plaques – thought to lead to Alzheimer's.
The scientists behind the study are suggesting that the plaque build-up might be the result of some kind of defence mechanism put in place by the body, as it tries to protect itself from attack.
Those sticky buildups of proteins then start damaging the connections between brain cells rather than guarding them.
For years, questions have been asked about how the onset of Alzheimer's is linked to the amyloid beta plaques found in the brains of those who have the disease. This new research further bolsters the hypothesis that the herpes virus is somehow involved.
"Our findings reveal a simple and direct mechanism by which herpes infections trigger the deposition of brain amyloid as a defense response in the brain," explains one of the researchers, Rudolph Tanzi from the MassGeneral Institute for Neurodegenerative Disease (MIND)."

I cared for Mom for seven years and learned so much from my experiences with her and Alzheimer's.
