Eli5: why can’t your brain stop you from getting sick?

1.20K views

When someone has an autoimmune disease, their brain is sending electrical waves to tell the immune system to attack what it believes to be bad cells. So why can’t you just tell your brain to stop sending those messages, since it’s the one sending them in the first place?

This isn’t remotely accurate, and doesn’t consider the many different mechanisms of immunopathology that *do* happen in various autoimmune disease. The whole premise is just wrong.

There are other nervous/hormonal axes involving the brain, though. The easiest way to conceptualize why those aren’t possible to consciously control is that they’re separately wired.
