A concussion of the brain, doctors call a violation of cerebral functions, the cause of which was an injury that is not associated with damage to blood vessels. Usually, the phenomenon is caused by the impact of the medulla on the inner side of the cranium, while the processes of the nerve cells are stretched. Although the injury is not considered severe, the consequences of a concussion can be quite serious.
Conduct and personality disorder
Often people who have suffered a concussion complain of irritability and aggressiveness that has appeared in their behavior. Even small troubles make them angry and nervous. They become either whiny or rude, their mood is constantly changing - from menacingly quiet to brightly hostile. They do not notice the joyful moments of life, see only the negative, take offense at the people around them, consider themselves misunderstood and deprived of attention. If similar symptoms were observed before the injury, then in the post-traumatic period they are noticeably exacerbated.
Scientists have noticed that if a person has an injured frontal part, then he is more likely to experience a state of euphoria, a decrease in critical attitude towards himself and his actions. It is perceived by others as arrogance or pride.
After a concussion, people often cannot concentrate, they get tired faster, especially after mental work. They become weather dependent, during rains, snowstorms, magnetic storms in the sun, solar and lunar eclipses, they suffer from headaches, note lethargy, weakness, depressed mood. Memory deteriorates: a person cannot remember the author of familiar lines or music, his calculations do not differ in accuracy, he gets confused in the rules of grammar, etc.
Traumatic brain injury can damage the autonomic nervous system, thereby increasing the risk of heart and vascular malfunction. Insufficient blood circulation disrupts the functions of all organs.
After a concussion, psychotic symptoms are not very common, and yet there are precedents. In these cases, they talk about damage to the areas of the brain responsible for vision, smell, hearing and speech perception. The affected person is haunted by hallucinations, i.e. he hears voices, sees some images. Sometimes he becomes obsessed with delusional ideas (for example, about domination over the world or global surveillance of him by intelligence services, etc.). This happens especially often with those who hit the back of the head.
There is an opinion that post-traumatic epilepsy can occur only with a severe head injury with memory loss or deep fainting. However, analysts talk about the possibility of persistent, recurring epileptic seizures, even with minor external influences. Or, doctors emphasize, there is an activation of hidden foci that did not let know about themselves before. This type of epilepsy occurs more often when the injury occurs in the temporal regions or the crown of the head.
Initial attacks can be mild, little attention is paid to them, and a person is left untreated for a long time. Meanwhile, this directly affects the cognitive abilities, the mental state of the patient.
Neuroses and psychosis
A fairly common consequence of a concussion of the brain is neurosis. Feelings of strong anxiety, fear, horror, an absolute inability to concentrate, to engage in educational or work activities, constantly haunting a sick person - these and other manifestations of neuroses prevent a person from fully living in society. Neuroses, if left untreated, can go to the stage of psychosis.And these are already cardinal violations in the perception of the surrounding world. Without professional treatment, psychoses threaten the development of dementia and other serious dysfunctions of the brain.
