6. Candida Albicans Fungus

Another from the world of fungi is something many people come in contact with quite often. However, not all have issues with it funny enough. Essentially, Candida Albicans is a pathogenic yeast that can mostly be found in human gut flora. It is often detected in the gastrointestinal tract and mouth and can be seen in about 40-60% of even healthy adults. It can cause the growth of Candida, which results in an infection known as Candidiasis. This infection involves the overgrowth of fungus.

While initially considered to be nothing of note if treated right away, a new study found that Candida Albicans could actually involve severe brain issues. A study done on mice found that it caused brain abnormalities that resembled that of Alzheimer’s Disease as well as memory issues. Imagine if this was weaponized and people could be controlled, all having no clue what happened due to the Alzheimer’s disease-like connection. That could become a true problem!

5. Toxoplasma Gondii

Toxoplasma Gondii happens to be a member of the parasite family. This is actually a brain parasite, which is mostly found in rats. Once a rat is infected by it, the parasite can manipulate the brain with the parasite. For example, instead of running away from cats looking to eat them, it’ll actually run toward them, seeking them out! A study on these infected rats found that they were attracted to the smell of cats and their urine.

They’ll often approach the cat and be killed and/or eaten by them, which results in the parasite moving onto the cat. This allows it to breed. Cases of the parasite have involved humans too, who likely got it from a cat, funny enough. Another study found that as many as 60 million people in the United States alone have been infected by or come in contact with Toxoplasma Gondii. If this is weaponized, it could control humans and make them become walking zombies looking for insane danger.

4. Mad Cow Disease

I know what you’re thinking, humans cannot get Mad Cow Disease due to the whole not being a cow thing. This is true, however, humans have an equivalent to this disease known as Variant Creutzfeldt-Jakob disease. This disease is caused by something called “prion.” It’s a type of protein that can trigger normal proteins in the brain to fold abnormally. This can actually affect both humans and animals. On top of this, it’s even possible to spread to humans via infected meat products.

This prion disorder of sorts is what triggers the Variant Creutzfeldt-Jakob disease. This is a degenerative brain disorder that leads to dementia and affects people similar to Alzheimer’s disease. The disease will cause memory issues, vision problems, memory loss, depression, loss of the ability to speak, and even sudden, jerky movements. All of this could lead one to believe they are seeing a walking zombie-like figure if they came in contact with a person that had a late-stage version of this.

3. Nanobots

We are closer and closer to finding ways to use nanobots to solve a ton of problems for both humans and animals alike. Right now, it is uncertain how far we can go with them. The theory is that the possibilities are endless due to the fact that you can pretty much put them into anything. Specifically, we can inject them into the bloodstream and have them attack certain parts of the body to help us defeat diseases.

Right now there are experiments with nanobots revolving around helping remove cancer issues too. However, due to the possibilities being so endless with nanobots, it’s at least possible to see them used for evil. If a person decided to weaponize them and use them to take over the brains of human beings…this could turn into a real zombie apocalypse. Imagine people walking around mindless, having to do whatever someone claimed. They could force them to kill and even eat other humans!

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.
