What do you know about the signs of brain damage?

Brain injury is a type of brain injury that results from a huge impact of an external force. Brain injury is a very serious disease, the mortality rate of mild brain injury is between 4 and 7 percent, and the mortality rate of severe brain injury is as high as 50 or 60 percent, and brain injury can also lead to many diseases, affecting people's normal life.

For one, brain damage can lead to motor dysfunction. If the brain's motor center is damaged, it will be unable to control its behavior like a normal person, and it will not even be able to control things with your hands.

Second, when the blood vessels in the patient's brain are damaged by external force, the patient's intracranial blood pressure will increase suddenly, resulting in brain herniation disease. Brain herniation is a brain disease with central fever and gastrointestinal bleeding as the main symptoms, and usually requires surgery to be complete**.

Third, for patients with cerebral contusion and brainstem injury, if the necessary drug treatment is not carried out in time, it will lead to brain lesions. If there is a residual blood clot in the brain, it will lead to the formation of a hematoma in the skull, and if there is a lack of nutrients in neurons, it will lead to a decrease in the recovery function of the nerves, so that the patient cannot maintain the original mental state, which is manifested as memory loss, inability to concentrate, etc.

When the cerebral blood vessels are injured and ruptured, causing intracranial hematoma, the patient has deepened consciousness disorder, the symptoms of increased intracranial pressure are aggravated, the symptoms of brain focal are aggravated and increased, and even the symptoms of cerebral herniation appear; Supratentorial intracranial hematomas often cause temporal uncinate hernias, which present with coma, ipsilateral, and contralateral hemiplegia; Infratentorial hematomas often cause cerebellar tonsillar herniation, and patients experience suboccipital pain, neck rigidity, and even respiratory arrest.

Brain injuries often lead to a variety of functional impairments, such as movement disorders, cranial nerve dysfunction, cognitive impairments, personality disorders, behavioural and emotional disorders, speech and swallowing disorders, and social skills disorders.

When it comes to brain injury**, many people have common misconceptions. Many people think that **** is redundant, and they feel that if they save their lives, they will have no worries. This kind of thinking is very likely to lead to the patient's lifelong inability to return to the original state of life, in the patient's condition is stable within one month to three months, is the best period for the patient to carry out ** training, must be treated positively, can not be lazy.

Brain injuries first lead to damage to the brain, and later on, can lead to increased intracranial pressure. The main clinical manifestations of increased intracranial pressure are headache, dizziness, and nausea and vomiting. Of course, severe intracranial pressure increases the risk of coma in patients with brain herniation, and even affects breathing and heartbeat.

The second part of the symptoms is that brain damage may lead to focal signs. For example, if a brain injury occurs near the nerves that control eye movements, it can cause eye movement dysfunction. If the optic nerve is damaged, it may lead to vision loss and visual field defects.

If the brain injury happens to damage the language center, it will cause the patient to have aphasia, poor speech, slurred speech and so on.

Severe pain, confusion, etc. severe pain and pain, accompanied by projectile vomiting; If you are delirious or have a severe injury, you may not be conscious.

Severe head pain, severe head pain is often accompanied by symptoms of nausea and vomiting, which is mostly persistent, projectile vomiting, different from ordinary vomiting. Headaches are also persistent, severe headaches, which are different from ordinary headaches and can have periods of complete ** in between.

Brain injury refers to the damage to the meninges, brain tissue, cerebral blood vessels and cranial nerves after being subjected to external forces.

The patient has a transient impairment of consciousness immediately after the injury, which lasts for a few seconds or minutes, generally not more than 30 minutes, and can be accompanied by ** pallor, sweating, blood pressure drop, bradycardia, shallow and slow breathing, decreased muscle tone, dull or absent physiological reflexes and other manifestations of autonomic nerve and brainstem dysfunction, most of them can not recall the recent situation at the time of injury and before the injury after waking up, and remember the past clearly, called retrograde amnesia, often headache, dizziness, insomnia, tinnitus, nausea, vomiting, emotional instability, Symptoms, such as memory loss, usually last days or weeks, and no positive signs on neurological examination. Depending on the location and severity of the injury, the clinical manifestations vary greatly, ranging from mild symptoms to coma or even death. Impairment of consciousness is one of the most prominent symptoms of cerebral contusion, and if the patient becomes unconscious immediately after the injury, he or she should be immediately sent to the hospital for treatment.

People who often sleep with their heads covered, because the carbon dioxide concentration in the quilt increases, the oxygen concentration continues to drop, and the humid air is inhaled for a long time, which is very harmful to the brain.

Staying up late, smoking, drinking, watching electronic products for a long time, eating some junk food; Because these will lead to endocrine disorders, which will affect the body's metabolism and make the brain not get certain nutrients and rest.

Stay up late. Because staying up late will make people's brain in a state of excitement, but at night the brain needs to rest, and staying up late will deplete the brain excessively.

Brain damage, the consequences are severe.

The brain is divided into left and right brains, and crosses control the human body, for example, the left brain controls the right side of the human body, and the right brain controls the left side of the body.

Moreover, there are five functional areas on the surface of the brain, which are the somatic motor center, the somatosensory center, the visual center, the auditory center and the language center.

For example, if you injure the left side of the brain, you will have an abnormality on the right side of the body, and you may lose sensation or movement.

Cerebellar lesions often present with cerebellar ataxia, damage to different parts and different incoming and outgoing nerve fibers, and the clinical manifestations are slightly different, and the common functional impairments mainly include the following aspects: (l) Posture and gait abnormalities: manifested as unsteady standing, widening of the gait base, staggering gait, swaying from side to side, truncal ataxia, and more common in cerebellar vermis injury.

Among them, the upper bandage is easy to fall forward, the inferior part is easy to fall backward, and the cerebellar hemisphere injury is easy to fall to the affected side. (2) Coordination disorder: due to coordination disorders such as speed, rhythm, amplitude and strength of voluntary movements, patients often have cerebellar clumsy syndromes such as poor dissociation, intention disorder, fine motor coordination, abnormal alternating movements, and dysgraphia (capitalization).

3) Speech disorder: ataxia of speech organs and muscles can appear slow speech, slurred speech, intermittent voice, pause, etc., plosives and poetic language. (4) Other symptoms:

Cerebellar lesions may also present with symptoms such as decreased muscle tone, rebound, and ataxia nystagmus.

That is, there will be unsteady walking, drinking water and choking

Analysis: Brain soft tissue injury is generally caused by external institutional pressure, and when it reaches a certain intensity, it induces damage and produces symptoms. Generally, it can be divided into two categories: acute injury and chronic cumulative injury.

When soft tissues are injured by blunt or sharp force, it can cause contusions or (and) lacerations of local soft tissues (including **, subcutaneous tissues, muscles, including nerves, blood vessels, and lymphatic tissues). Patients with bleeding around the eyes, nose, and ears.

Patients who develop nausea and vomiting after injury. Progressively blurred patients. Patients with spasticity, paralysis, and speech impairment.

Patients with severe headaches. Immediately take to hospital**. Wish**.
