From Wikipedia...
"Microglia are a type of neuroglia (glial cell) located throughout the brain and spinal cord.[1] Microglia account for 10–15% of all cells found within the brain.[2] As the resident macrophage cells, they act as the first and main form of active immune defence in the central nervous system (CNS).[3] Microglia (and other neuroglia including astrocytes) are distributed in large non-overlapping regions throughout the CNS.[4][5] Microglia are key cells in overall brain maintenance—they are constantly scavenging the CNS for plaques, damaged or unnecessary neurons and synapses, and infectious agents.[6] Since these processes must be efficient to prevent potentially fatal damage, microglia are extremely sensitive to even small pathological changes in the CNS.[7] This sensitivity is achieved in part by the presence of unique potassium channels that respond to even small changes in extracellular potassium.[6]"

10 to 15% of the brian?

What the heck! Let's kill them!!! Let's get the bastards!!!

And ANOTHER 10 to 15% of the BRAIN...

I've been of the opinion that aluminum is responsible. It was rarer than gold before a process to extract it cheaply was developed. The outbreak of dementia seems to follow it's relative abundance.

Sounds like an autoimmune response. Which means, the body’s own devices attacking others.

It’s not fun, and not worth keeping unless there is a way to “block” them.
