Symptom #2: Fatigue
A big brain is a very useful thing. It helps us to hunt, to protect ourselves and, in the cases of humans, it allows us to use science to manipulate the world around us. Despite all the many positives of having a big brain, though, it comes at a price.
A large brain needs a lot of energy to keep it nourished. This is not usually a problem for us but when something goes wrong, a lot of energy is needed to help fix the brain. This means that even more energy and nutrients are diverted away from the rest of the body and toward the brain. This leaves the rest of the body without the nutrition it needs, leaving us feeling fatigued.
