You’ve probably heard of many diseases and health problems that befall humanoids, but there are some strange syndromes out there that you probably aren’t familiar with. How many of these unusual medical conditions have you heard of?

Exploding head syndrome is a strange sleep disorder where people hear a loud noise or explosion in their head.
Exploding Head Syndrome
Imagine what it would be like to be sleeping soundly, only to be jolted out of a dead sleep by the sound of an explosion tearing through your head? No, you haven’t been shot; you have exploding head syndrome. This strange ailment, also known as hypnagogic or “exploding” sleep disorder, is a rare condition where a sufferer hears loud noises in their head. The most common time these noises occur is while falling asleep. The noises can vary from thunderclaps to gunshots, but the sounds can be bizarre, like creaking doors. In most cases, the sound will last only a few seconds, but they can be more persistent and associated with other symptoms, like seeing a flashing light.
Exploding head syndrome is most common in women over 50 who are stressed or fatigued, but it also occurs in young adults too. According to Cleveland Clinic, 16% of college students reported it in one study. It’s not dangerous — although it can be scary for those who experience it. Unfortunately, researchers have yet to understand why some people experience it and others don’t.

Foreign Accent Syndrome was first described in a Norwegian woman, who was hit in the head by a bomb fragment during World War II and took on a strong German accent.
Foreign Accent Syndrome
Foreign accent syndrome (FAS) is a condition in which a person speaks with a different accent. Suddenly, you sound like you’re from another country. Some people with this syndrome have another condition, like a brain tumor or multiple sclerosis, but there’s been at least one case of a woman developing it after dental surgery. Although rare, there is no cure. The treatment most doctors recommend is speech therapy to correct the accent.
A neurologist in Norway first described the condition in 1941. A Norwegian woman hit by a fragment from a bomb during World War II began speaking with a strong German accent. So strong was the accent that she became the target of hate speech directed against Germans. The disease has since been documented throughout Europe and North America, including cases of people born and raised in the U.S.

Tree Man Disease
Tree Man disease, also known as epidermodysplasia verruciformis, causes a type of viral wart to grow all over the body. The warts are not contagious, and doctors can remove them with surgery, but they tend to grow back. Plus, the warts are associated with a higher risk of cutaneous cancers (cancers affecting the skin). This disorder usually runs in families.
Interestingly, people with tree man disease have problems regulating the amount of zinc inside cells, including…
