Scientists named the 5 most rare and mysterious diseases

Scientists called the most strange diseases, about the existence of which few people have heard, but, despite this, they still exist. In reality, specialists discovered a huge number of rare pathologies (a total of more than 7,000), but every day around the world, physicians have to meet new unexplained conditions of the human body. Some pathologies seem so terrifying that it is difficult to believe in their existence.

The disease or disorder is considered rare if in the country they are sick less than 200 thousand people, and the pathologies described below are considered the rarest, but still taking place.

The syndrome of "Another's hand" is manifested in the involuntary actions of one hand, in some cases of legs. Usually, in this disorder, a person commits any movement, for example, starts unbuttoning the shirt, stroking himself or others around the head, throwing objects, etc., but in severe cases his own hand can behave aggressively. A similar case was described about 20 years ago - an elderly patient suffered from her own hand, which could hit her and several times even started to strangle.

When X-ray examination of patients, specialists found out that pathology is caused by lesions of various parts of the brain, including those responsible for movement. Violations of this nature often occur after disorders of cerebral circulation, with diseases of the nervous system, brain tumors, convulsions. Now doctors say that such a disorder has not occurred for several years.

Syndrome of a stone man or fibrodysplasia is characterized by the gradual hardening of muscles and connective tissue. Over time, complete immobility comes, as if the second skeleton is growing. The disease begins with the deformation of the thumbs, and there are also problems with the respiratory system and motor activity.

Pathology is caused by genetic disorders and is detected in 1 out of 2 million people on the planet.

The syndrome of walking corpse or Kotara syndrome refers to mental disorders. For the first time the disease was described by Jules Kotard more than 130 years ago. With this disorder, the patient is confident of the absence of any parts of the body, and also is sure that he is already dead, so he ceases to eat, drink water, bathe and is constantly drawn to the cemetery.

The most striking case in the history of medicine was the case of a patient named Graham, who after a suicide attempt assured the doctors that he was dead (Graham assured doctors that his brain was dead). But after scanning the doctors were extremely surprised - the patient's brain was in the vegetative state, as if under anesthesia or in a sleepy state (coma).

The syndrome of Alice in Wonderland is expressed in a violation of the perception of the world. Pathology was named after the eponymous work of Lewis Carol.

With this pathology, patients usually see their body parts differently - they seem to them more or less than usual. Most pathology is detected in children, usually in adolescence, the disease passes, but sometimes a person can suffer from it all his life. The reasons for the development of the disease, to date have not been clarified.

Allergy to water seems a rather strange disease, since the person himself is more than half the water. In medicine, this condition is called aqua urticaria and is expressed in severe itching of the skin, after water enters it. With this pathology, a person can not swim, fall under the rain, swim in the pool or the sea, etc., besides, own tears can provoke severe itching. Because the allergy is caused not by chemical irritants, antiallergic drugs do not help.
