11 extremely rare mental health disorders that will shock you!

We don't all look at the world in the same way.

The brain's limitless energy has been a subject of intrigue and mystery for scientists and researchers since time immemorial. Nobody knows what a full-throttle brain can do. It is the brain's energy that led to geniuses like Einstein.

On the other side of the spectrum, it is the same energy that showed its dark side in people like the recent mass murderer Stephen Paddock.

Oliver Sacks' classic book The Man Who Mistook His Wife for a Hat introduced the world to an unheard of brain disorder, but that was only the tip of the iceberg.

Read into some of the most bizarre mental conditions and disorders out there that have even left scientists and doctors ina state ofhelpless dilemma and will change your perception of reality. 

#1 Boanthropy: a cow hiding inside the human brain


A delusional disorder in which a person believes himself to be a cow or an ox, boanthropy is a rare mental disorder. Scientists believe that the disorder begins with a dream and then oversteps reality, thus taking over the person's psyche and eventually growing into a full-scale state of delusion. In some cases, hypnotism has also led to an individual developing this condition.

According to The Book of Daniel, Nebuchadnezzar, King of the Neo-Babylonian Empire, was said to be suffering from the disorder. The book stated that the King 'was driven from men, and did eat grass as oxen.'

#2 Mary Hart Syndrome: Seizure on hearing Mary Hart's voice


Outrightly bizarre, there have been reported cases of people getting a seizure attack upon hearing the voice of Mary Hart, a prominent TV personality.

A doctor who was investigating the case, revealed that a patient who claimed to get seizure attack after hearing Mary Hart's voice, was indeed true.

The doctor also reported that the woman would clutch her head, end up confused and dazed, giving them a peek into the symptoms of this condition. This syndrome has affected only those who have had a previous history of seizure attacks.

#3 Capgras delusion: Advanced schizophrenia


This delusion compels a person to think that their loved ones have been replaced by imposters—even aliens and robots. Common among patients who suffer from paranoid schizophrenia or have suffered a brain injury and even dementia, this disorder afflicts females more than males.

Case in point: A 36-year-old woman, post her child's birth, developed a delusion that her son and other family members had been replaced by imposters. She lived with the delusion for five years. Finally, the woman was given electroconvulsive therapy (electric shocks are passed through the brain to induce a seizure), and recovery fell in place gradually.

#4 Alien Hand Syndrome: Out-of-body experience

This is a condition in which the patient's arm functions like it has a mind of its own. It swings, responds, grabs, moves around, all at its own accord, without the person having any control over the movements. This condition has also led to depression in many patients as they develop a delusion that there is somebody else controlling them.

The condition may be caused when the connections between the brain's two hemispheres are severed, but can also happen after a stroke or some other brain injury. Only about four dozen cases of alien hand syndrome have been reported in the world.

#5 Hemispatial neglect: Half-dead and half-alive brain.


This condition is common among people who have suffered a stroke or damage to one side of the brain. The person is unable to process information received from that side of the body or environment (often the side opposite to the brain injury).
