Imagine a big button in your brain. To go to sleep you turn off the lights, close the curtains, tell the body to get into rest mode and once ready press the button.
Anesthesia is someone sprinting in, and slamming the button down without turning off the lights or any of that. Just shuts off consciousness.
In Fatal Insomnia the button isn’t connected to anything anymore. As the disease gets worse the button basically melts too. Theres nothing to hijack.
Thats because fatal insomnia is a very rare prion disease. This means a very important protein in the nervous system misfolds. Misfolded proteins do not function correctly if at all, and build up in the brain.
Its like CJD another prion disease. The nervous system just goes bad and we can’t do anything.
