When it comes to diseases or disorders, you have probably just encountered the usual terms like cancer, diabetes, or even obesity. But what if you get to encounter someone who experiences a seizure upon hearing a certain voice of a familiar person? What will you do if one day you see your hand having a life of its own?

These are actual symptoms of the weirdest disorders you can ever encounter in your life as gathered impressively by Linda Melone of the Health Department of MSN.

Here are some of the weirdest in the list:

Alien Hand Syndrome

This syndrome is when one of your hands suddenly works all on its own. Neurologist Anthony P. Garcia explains that this happens to patients whose two sections of the brain severely damaged. It becomes disconnected from the central neural system that is in charge of the body's voluntary actions. There is no cure to this yet except for just keeping that other hand busy all the time.

Mary Hart or Reflex Epilepsy

It was a 45-year-old woman who first suffered from this disorder during the nineties. The seizures happen each time she hears the voice of TV show host Mary Hart. According to physician Cynthia Harden, this epilepsy can start from anything at all. This is because it is considered as spontaneous seizures.

Spontaneous Human Combustion

This is just about a body suddenly igniting into flames without any given reason. This remains as one of the mysteries yet to be unraveled by Science experts. In fact, the most recent case of possible SHC is that of baby Rahul from India.

Werewolf Syndrome

What do werewolves have? Lots of hair! Then this syndrome is about having excessive hair growth on the face and other parts of the body. According to author and New York based dermatologist Debra Jaliman, the excessive hair are made visible since the time the person is born.

Moebius Syndrome

This rare case is a neurological condition that involves the lack of capacity of a person to form various facial expressions. There is no other cure for this syndrome but supportive care can help. This genetic disorder happens to 10 in every million births.
