What causes brain damage? What do you know about the signs of brain damage?

Causes of head injury include trauma, vascular invasion, collateral injury from surgery, and tumor invasion. In a narrow sense, head injury mainly refers to traumatic brain injury, which includes: indirect violence and direct violence causing damage to brain tissue and scalp and skull.

Brain injury, what's going on? Brain injury is one, to be a big noun. Referring to brain injury in general, we refer to a series of diseases such as brain trauma, which causes damage to brain tissue, caused by brain nerve cells, degeneration and necrosis, or apoptosis, such as traumatic brain injury, which causes brain cell necrosis and brain damage.

In addition, cerebral ischemia and hypoxia caused by more reasons, such as drowning, gas poisoning, etc., cause necrosis of troublesome cells. Sometimes we also refer specifically to the necrosis, degeneration, and apoptosis of brain nerve cells.

The history of staying up late and not sleeping well for a long time is about ten years From junior high school to the present, I have recently found that my cognitive ability has declined, and it is said that staying up late has irreversible damage to the brain.

Brain injury is a condition in which the head is traumatized due to various causes, and the causes of brain injury are generally as follows.

A disorder of brain development, often combined with physical retardation, malnutrition, cerebral palsy, cognitive impairment, etc.

Second, head trauma, including closed head injury and open head injury, is mostly caused by car accidents, fights, falls from heights, etc., and of course, damage caused by invasive operations such as surgery.

Third, brain tumors, brain tumors can directly or indirectly cause damage to the brain tissue nervous system, and produce a series of symptoms, other causes are encephalitis, cerebrovascular diseases, cerebral ischemia, hypoxia symptoms, metabolic diseases, endocrine disorders, poisoning and so on.

Open brain injuries are often directly caused by sharp or firearms, and are accompanied by scalp lacerations, skull fractures, dural rupture, and cerebrospinal fluid leakage. Closed brain injury is caused by blunt objects or indirect violence on the head, often with the scalp and skull intact.

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.

Brain cells, which play an important role in brain growth and development, are mainly composed of the following eight kinds of fats, calcium, vitamin C, sugar, protein, group vitamins, vitamin A and vitamin E, many of which are rich in eight substances, can be counted as brain food.

Drugs to nourish brain cells include adenosine triphosphate, coenzyme A, brain heart comfort, cod liver, vitamins, you can eat some drugs that invigorate blood and remove blood stasis, such as salvia tablets, nimodipine to improve, and if you have time, you can inhale oxygen outside to help recovery.

Conduct more ** training, and at the same time according to the degree of damage. Brain development courses are also available, 2447714398

l. Ataxia: due to the lack of cerebellar regulation, the patient is unstable in standing, shaking, and unstable gait, which is the gait of a drunk: when walking, the legs are far apart, swaying from side to side, and the upper limbs are flexed and stretched forward as if they are about to fall.

Difficulty standing on the feet. Generally, you cannot stand on one foot. Handwriting abnormalities are also a manifestation of arm and hand ataxia, with irregular handwriting and tremor of strokes.

Generally, writing is too large, and paralysis tremor is mostly writing too small. 2 Burst language: manifested by slow speech, articulation of punching, monotonous, nasal.

There is a "language similar to a bulbar lesion", but the latter is more peculiar and clumsy, and there is often vocal cord or soft jaw paralysis on objective examination, whereas cerebellar speech is ataxia without paralysis. 3 Poor distance resolution or scale impairment. 4 Alternating dyskinesia.

5 Synergy disorders. 6 Counterattack. 7 nystagmus.

Symptoms of the prelude to a stroke in the cerebellum, a simple test that detects the state of cerebellar damage.
