Most of us all already aware of schizophrenia, OCD or even Bipolar disorder. But there exist some disorders that are rare and fairly unknown in the society. So here some are usual, uncommon disorders that you should know about.

1) Pica

Mostly seen in pregnant women, small children or people with developmental disabilities, this disorder is characterized by an appetite for substances that don’t offer any nutrition like ice or even non-food substances like paper or paint.

This disorder is particularly harmful as that can lead to issues like food poisoning, gastro-intestinal obstruction or even tearing in the stomach. Pica is also found in animals and is most commonly seen in dogs.

2) Mary- Hart syndrome:

Mary-Hart is an American TV celebrity who co-hosted a popular entertainment show, “Entertainment Tonight”. Distinctively, there have been many instances that show people experiencing seizures upon hearing this celebrity’s voice.

Though it has been reported that the only people who experience this kind of syndrome are the people who suffer from seizures from other reasons as well.


3) Foreign Accent Syndrome:

A rare mental condition and a speech disorder, Foreign Accent Syndrome (FAS) is characterized by a development of a foreign accent (different from their native accent) without having acquired it from the foreign accent’s place of origin.

This syndrome is usually a result of stroke, head trauma, migraine or developmental problems. First reported in 1907, there have been 62 recorded cases between 1941 to 2009.

4) Autophagia:

There have been a lot of cases in which people enjoy eating other people’s flesh. But autophagia is a condition of eating your body parts by simply biting or chewing impulsively.
This disorder sometimes accompanies other disorders like psychosis or schizophrenia.

Autophagia is also found in rats, where they start by biting their nails and end up eating their toes. This disorder can be seen ranging from a mild disorder to fatal.


5) Boanthropy:

This is a psychological disorder in which a person believes himself to be a bovine, mostly a cow or an ox. The disorder usually starts out as a dream and goes on to pervade the waking mind, eventually taking hold as a full-blown delusion.

According to the Book of Daniel, Nebuchadnezzar, King of the Neo-Babylonian Empire, is generally thought to have suffered from this condition. The book states that he “was driven from men, and did eat grass as oxen.”


6) Alien Hand Syndrome:

Alien hand syndrome occurs when a person’s arm appears to move involuntarily or grab hold of things without the control of the person. It is caused by a conflict between the left and right parts of the brain or mixing of damaged brain wires. It also occurs in some cases after brain surgery, stroke, infection, tumor, aneurysm and specific degenerative brain conditions such as Alzheimer’s disease.

Though there is no cure for this disease, the symptoms can be reduced by keeping the alien hand occupied and involved in a task.
