Brain Dislocation

What is brain dislocation? Let's try to answer this question and understand what disease may be associated with displacement of the cerebral hemispheres.

Brain dislocation is damage to the skull that causes nerve tissue to move out of its normal position and become compressed inside the skull. This disease is one of the most serious injuries to the central nervous system that can occur as a result of head injury or brain disease (eg, epilepsy).

The causes of brain dislocation can be different. Most often, this pathology is caused by a head injury, for example, in a car accident, in any other type of transport injury, or when hitting the head on a surface at work or at home. Also, dislocation develops more often in children than in adults, when it grows and reaches adult size. Congenital pathology is possible with increased intracranial pressure, head injuries, hemorrhage, etc.

In every person, all parts of the brain are located outside the normal boundaries of their space, deviating up or down from the average position by only a few millimeters. However, this “norm” is different in men and women: they have slightly different shapes and locations of the semilunar protrusions on the outside of the skull. Brain dysplasia can be congenital or acquired during life. This leads to excessive stretching of the meninges due to, for example, the congenital position of the cerebral hemispheres or the formation of cysts in the brain and an increase in the speed of blood flow between the blood and areas of the brain located closer to the membrane, increasing intracranial pressure, which is usually accompanied by headache. It is normal for children and young adults to have misaligned brains as they grow and the shape of their skull changes. The disease is characterized by a different clinical picture. With mild severity, symptoms do not appear at all or the symptoms are mild. There are no impairments of consciousness or psychomotor functions. There is a slight stiffness of the neck muscles (when the head is fixed), fewer of these symptoms, but nystagmus is present - oscillatory movement of the eyes. For this reason, a person cannot focus his gaze on any specific object or object. A severe form of concussion is characterized by a violation of the victim’s consciousness: he does not come to his senses after loss of consciousness for a long time; signs of status epilepticus, seizures; hemiplegia, paralysis of individual limbs; bradycardia (slow heart rate) and irregular heart rhythm. It is also possible to develop mydriasis (dilated pupil). A drop in blood pressure is all symptoms associated with the development of a hypotensive state. The patient may lose consciousness. Involuntary loss of feces is another symptom.
