2. Cotard’s Syndrome

Cotard’s Syndrome is a rare disorder that is quite horrific to experience. People often call it the “walking corpse syndrome,” if that tells you anything. This mental disorder causes people to have the delusional belief that they are already dead, do not exist, are putrefying, or they’ve lost their blood and/or internal organs. Essentially, these people assume are walking, talking members of the undead. The weird part of this is that they could have conversations with people that are alive.

They will then just have the belief that they are ghostly figures, even if they need to do things normal humans must do like eat and use the restroom. This would be a compelling thing to use as a real zombie apocalypse, at least for those with this disorder. They could assume all are dead, though it would only be something they would see. This would not affect the rest of the world unless these people did something insane. However, we never said this apocalypse had to be something for all.

1. Neurogenesis

Likely the most compelling possibility for a real zombie apocalypse can come from Neurogenesis. This is, in large thanks, to stem cell research that will soon make it possible for people to regenerate decaying organs. The procedure would work for most organs in our bodies but sadly not on the brain. Essentially, when we die our brain actually begins decaying from the outside in. The outer layers of the brain are pretty important and affect our memory, emotions, decision-making, logic, etc.

Unless you decide to revive someone immediately, their outer brain function will be too far gone to bring them back. In a situation such as this, you could technically have an ordeal science has yet to see. If you could bring someone back to life who simply had the outer layer of their brain erased, they’d still be able to live due to the inner parts operating properly. They would just be a mindless zombie. If someone were to find a way to revive the recently dead using Neurogenesis, they could create an army of undead zombies.
