BRAIN DISORDERS

TRANSVERSE MYELITIS- Transverse myelitis, also known as TM is a neurologic syndrome caused by inflammation of gray and white matter of the spinal cord.

10 INCREDIBLY STRANGE BRAIN DISORDERS
You're used to relying on your brain. Whatever else happens, your personal lump of gray matter will take in the world, and respond to it in a fluid and predictable way. But actually, whatever your brain does is made up of many successive mental steps — and if just one of those steps fails, you'll find yourself behaving very differently. Here are 10 weird and highly specific brain conditions, and what they each show us about the human brain.

10. ASTASIA-ABASIA PATIENTS ARE ALWAYS ON THE VERGE OF FALLING Astasia-Abasia is also known as Blocq's Disease, after Paul Blocq, the French doctor who first described it. It's the inability to stand or walk properly, but there's more to it. At first, a person with this condition appears very drunk. Patients lurch when they try to stand or walk. Patients seem dangerous to themselves. They overbalance extravagantly, always catching themselves at the last moment. But that's the condition — they always catch themselves. People with Blocq's Disease almost never hurt themselves. They only fall when a doctor, a loved one, or a soft place on the ground is available. Often this condition is in response to stress. The most famous case of this happened in the 1960s, when not one but two cadets at West Point came down with the condition, doctors believe as a response to the pressure of training at the prestigious school.

9. ANOSOGNIA PATIENTS ARE UNABLE TO RECOGNIZE THEIR OWN INJURIES Anosognia arises in conjunction with other injuries — generally strokes and blindness. People who have lost the ability to control one half of their body will say that they just don't want to move that part of their body. They'll say that that half of the body is really working normally, after all. When doctors show that it isn't working, they'll say that the body parts that the doctors are pointing to belong to someone else, or even that they have three hands, arms, or legs, and are moving the ones that the doctors don't see. There was even a case of a woman who had gone almost completely blind but insisted that she could see normally - cobbling together a 'vision' of what was happening around her from glimpses on the undamaged parts of her eyes, from memories, and from any sounds that she could hear around her.

8. BROCA'S APHASIA PATIENTS ARE ABLE TO DO EVERYTHING BUT SPEAK Patients with Broca's Aphasia are able to write, to read, to listen and understand people, and are able to talk - but not able to form many coherent words. The condition is the result of an injury to Broca's area, the patient's ability to control what their mouths are saying goes away. Some patients are able to manage about four words, but most lose their ability to say what they want. Occasionally, they even lose the ability to understand that they aren't saying what they mean to say. One of the most famous cases of this was a man who simply repeated "Tono tono tono tono tono," to every question asked him. Although he could comprehend everything, he couldn't make his mouth say the words he needed to respond.

7. PALINOPSIA PATIENTS LITERALLY CANNOT UNSEE THINGS
Palinopsia is not actually a medical disorder. It's just the after-image that most people see after they look away from bright objects. Sometimes, though, it lasts a little too long. A seventy-three-year-old woman attended a Christmas party the day after a very bad headache and noticed that, after she looked at a Santa Claus who was working at the party, she saw a Santa beard on everyone's face for the rest of the party. Days later she still saw people in red Santa hats and red Santa jackets walking around the streets. Another woman saw parts of her husband's face superimposed on everything, or halos of light from a window spilling...
