Sudden loss of consciousness in the brain, what is the cause of sudden loss of consciousness

Sudden loss of consciousness, consider a syncopal episode, mainly because of a sudden decrease or interruption of cerebral blood flow, resulting in a brief episodic loss of consciousness. The common causes are as follows: 1. The most common is cardiogenic syncope, which is due to various heart diseases, such as arrhythmia or bradycardia, tachycardia, and cardiac arrest, resulting in syncopal episodes.

2. Brain-derived syncope may be caused by various cerebrovascular diseases, such as cerebral infarction or cerebral embolism, which cause short-term insufficient blood supply to the whole brain, and brain-derived syncope will occur. 3. Vasoinhibitory syncope, common in young women, such as thin physique, after staying up late or tired, suddenly blackened eyes and lost consciousness. 4. Situational syncope, such as some men suddenly lose consciousness after urinating at night.

Summary. There are many situations of sudden loss of consciousness, the common is caused by hunger or low physical fitness, if you have this feeling after not eating or exercising for a long time, it means that you have to replenish energy, if you have this feeling at the moment of standing up after a long time of squatting, it is your physical fitness is relatively low, it is recommended that you exercise properly.

What is the cause of the sudden loss of consciousness.

Hello, can you describe the circumstances under which you suddenly lost consciousness?

There are many situations of sudden loss of consciousness, the common is caused by hunger or low physical fitness, if you have this feeling after not eating or exercising for a long time, it means that you have to replenish energy, if you have this feeling at the moment of standing up after a long time of squatting, it is your physical fitness is relatively low, it is recommended that you exercise properly.

Of course, it is not excluded that you may have a disease, but if this condition affects your normal life or is more frequent, it is recommended that you go to the hospital for a check-up.

Hello dear<>

The answer for you is as follows: to determine whether a person has really lost consciousness, it is best to go to an authoritative institution to undergo psychological testing and the identification of psychological experts, and you can also pass the CT examination of the brain or department to check whether there are organic lesions in the relevant department. Amnesia is a disorder of memory confusion, simply put, loss of memory.

There are two main types of causes of this disease, the first of which is organic causes, that is, lesions in the part of the brain. For example, traumatic brain injury, or cerebrovascular disease cerebral infarction caused damage to the cerebral cortex such as the frontal and temporal lobes, which may cause amnesia. The second is caused by psychological factors, such as depression and anxiety, or some emergency events that cause a psychological defense mechanism.

I hope my answers help.

You may have vasosuppressive syncope.

A person who faints suddenly, accompanied by a transient impairment of consciousness, is called syncope.

The most common cause of syncope is vasosuppressive syncope (also known as isolated syncope).

Syncope can be divided into 4 categories:

A reflex syncope:

1 Vasoinhibitory syncope – the most common, accounting for more than 50%. Syncope is often induced by fatigue, fasting, poor ventilation and mental factors (tension, pain); There are prodromal symptoms such as transient dizziness, dizziness, weakness, and limb weakness before syncope; Syncope is accompanied by slow pulse, decreased blood pressure, paleness, cold sweats, etc., and the recovery is rapid without obvious sequelae.

2 Orthostatic hypotension - often occurs when the supine position is converted to an upright position, and can also occur when standing for a long time, and the blood pressure drops during syncope without obvious changes in heart rate.

3 Micturition syncope - mostly in young and middle-aged men, syncope often occurs during or after urination.

4 Carotid sinus syncope – seen in middle age and above, syncope is associated with a sudden turn of the head.

2. Hypoglycemic syncope:

Seizures are associated with fasting and can also occur 2 to 4 hours after a meal, syncope often occurs slowly, with fatigue, dizziness, sweating, and hunger, and recovery is slow, and it may improve after thirst for sugar water. There is no significant change in blood pressure and pulse at the time of attack, and blood glucose levels often do not match symptoms.

3. Cardiac syncope:

Patients often have a history of heart disease, often due to severe arrhythmias, such as high tachycardia, bradycardia (less than 40 points) or asystole, and obstruction of cardiac blood discharge due to valvular heart disease, resulting in cerebral insufficiency and syncope.

4. Cerebral syncope:

Common cerebrovascular diseases such as cerebral arteriosclerosis and transient cerebral ischemia are caused, mostly in elderly patients.

If it is clear**, the following tests can be done:

ECG or 24-hour Holter ECG, cardiac ultrasound, EEG, cervical spine X-ray, blood glucose, etc. Neurologic and autonomic function tests, such as the recumbent stand test and the upright tilt test, are helpful in the diagnosis of vascular syncope.

As we grow older, many people will gradually have some memory problems that they can also perceive, such as not being able to remember other people's names, etc., which is relatively normal, and if it does not affect life very much, it is not necessary to worry about it.

You can't remember what happened recently, you can only remember what happened earlier, and there is a condition called "amnesia", in which the patient cannot form a normal memory of recent events, but your symptoms do not seem to be severe enough to suffer from that condition. Memory-related disorders** are in the brain and are usually caused by degeneration of brain tissue or damage to brain tissue.

If 1, it is not an elderly person (brain tissue degeneration) 2, there has been no recent brain injury, such as brain ** or the like, then it should be a sign of memory loss. 1. Eat more foods that nourish the brain, especially foods rich in lecithin (such as soybeans, egg yolks and animal liver) are good for memory; 2. Use more brains, the more you learn, the better your brains will be; 3. Don't be too tired and pay attention to rest; 4. Regulate emotions, excessive sadness, anger and other emotions may also cause memory loss.

Ghost press refers to sleeping and suddenly having consciousness, but the body cannot move. In sleep neuromedicine, this is a symptom of sleep paralysis. The sleep cycle is from the onset of sleep, light sleep, deep sleep, deep sleep, and finally rapid eye movement (dreaming).

Sleep paralysis is the REM stage that occurs during the sleep cycle, which is the sleep cycle when we enter deep sleep and start dreaming. In REM sleep, a person's dreaming activity accelerates and the body's voluntary muscles begin to rest, a temporary paralysis that sometimes causes the person to remain unable to move after waking up from a dream. During REM, our skeletal muscles, except for the respiratory and eye muscles, are in a state of extremely low tension.

It's a protective way to prevent us from hurting ourselves or the person next to us when we make a move in the dream. Sleep paralysis is caused by the fact that during the REM period, the consciousness has been awakened, but the muscles of the limbs are still in a state of low tension, resulting in the situation of not listening to the command of consciousness. Hallucinations are often caused by abnormal conditions in the body that cannot be explained by the brain, coupled with fearful fantasies.

Ghost presses can occur during lunch breaks and during evening sleep. In fact, this situation has nothing to do with ghosts at all, and there is a formal scientific name in medicine: sleep paralysis.

Sleep paralysis usually occurs when the patient has just fallen asleep or is about to wake up, and the person feels that he has woken up and can hear the sounds around him and see the images around him, but the body cannot move, nor can he make a sound, and sometimes he has hallucinations. Most people panic at this time, but fortunately, most of them will slowly or suddenly recover their movements over a period of time. Because of the panic feeling at the time of the attack, many people will feel scared after waking up, and intuitively think that it is caused by the suppression of some unknown object, so there is a saying of "ghost press".

This condition is usually caused by a brief lack of oxygen in the brain, and the brain is awake, but your innervation nerve is not transmitted, so you want to move, but you can't move.

This phenomenon is commonly known as ghost pressing, and there are many theories about this phenomenon, some say that the hand is placed on the heart position, and the heart is compressed by the pressure of the whole body blood supply; Some say that it is caused by excessive mental pressure and often staying up late to rest; However, this phenomenon is good if it is affected by external factors, so don't worry.

Problems with the regulation of the nervous system. It is normal for the brain to wake up suddenly, and the body to react lag.

This is very normal, just a physiological reaction of the human body, which was called a ghost press in ancient times. Almost everyone has had this experience.

I've been to this situation too, and more than once. The head is clear from the brain, but Bai can't move the body. Yes.

Du feels so scared, some people say that this is a DAO ghost press, although science can't explain it, but I'm not superstitious. So I still think it's a physical condition.,Maybe it's more tired.,Anyway, it's nothing to do with ghosts.。 Don't worry about this, it'll be fine when it's over.

Every time I wake up, I breathe a sigh of relief and hope I don't have it again next time.

It is a natural phenomenon that the brain is conscious but unable to move due to the hand pressing on the heart or a heavy object pressing on the chest.

This is because some nerves may be pressed while sleeping.

Maybe it was a light sleep, and I didn't sleep very much, which caused the brain to be conscious all the time.

The next time it happens, think about what you're most angry about, and you'll be fine.

The truth is that you don't wake up at all in the light sleep stage

Why do we often feel like we're awake and conscious when we sleep, but our bodies can't move and can't. So at this point our brains are"Sober", but the body muscles are"Relaxing", if this time dreams.

You're sick, and you have to go to the doctor instead of pondering here. Sudden loss of consciousness I think is quite dangerous, and if you let it continue, you will get seriously ill.

I think if you often have such symptoms, you should still pay attention, and it is best to go to the hospital for a comprehensive examination, so that you can rest assured and see if there are any changes in your body? Or if there is something similar, you should also pay attention to it in the future, otherwise it will be too late to regret it when it really happens.

You can go for a brain examination to see if there is any brain disease, I have a fellow who has cerebral necrosis, fainted and died, and he has a large area of cerebral infarction necrosis, so there is something that is not under his control and needs to be examined in the brain.

It is estimated that your brain should not think too much, overwork, especially new problems, it will be very laborious. Either you go to the hospital and have your brain checked, so you can rest assured. Either you have a good attitude, exercise more, and do what suits you.

Your condition is a kind of cerebral infarction. The blood supply can't keep up. You should pay attention. It's time to go. Hospital visits. Do it. ct。Check it out. Depending on the results, you should see a doctor. You must not take it seriously.

Then you should go to the hospital for a full body check-up!

You recommend that you see a neurologist as soon as possible, because there is a high possibility of insufficient blood supply to the brain. It is generally related to cervical spondylosis and arteriosclerosis. It is recommended that you see your local neurologist to take nimodipine under their guidance Cispiline Cervil Salvia, intramuscular or intravenous infusion of petadine, and traction, physiotherapy, infrared, and massage **.

Be sure to quit smoking, eat a low-fat diet, avoid maintaining a posture for a long time to work and study, especially work and study with your head down, and take a break of about 10 minutes every 10 hours or so. Sleeping pillows that don't fit well may also aggravate this symptom. Pay attention to adjusting the height of the pillow.

The main causes of sudden loss of consciousness are syncope and seizures. Syncope refers to the sudden decrease in cerebral blood flow caused by transient, episodic loss of consciousness, common syncope has the following four types, 1. Vascular inhibitory syncope: it is common in young women, who are relatively thin and weak, due to staying up late, tiredness or sudden blackening in front of the eyes and loss of consciousness after standing for a long time during menstruation, but it can be quickly relieved after lying in bed.

2. Cardiogenic syncope: It is a sudden syncope due to various heart diseases, arrhythmias, bradycardia or tachycardia, and cardiac arrest. 3. Brain-induced syncope:

It includes cerebral syncope caused by insufficiency of whole cerebral blood supply caused by various cerebrovascular infarctions, transient ischemic attack, hypertensive encephalopathy and ischemia and hemorrhage of the brainstem.

Sudden loss of consciousness may be due to episodes of hypoglycemia or due to vasosuppressive syncope. Epilepsy, severe arrhythmias, and old strokes are induced by factors such as admission to the hospital for routine blood tests, brain CT tests, and if hypoglycemic seizures are diagnosed. Just take this glucose solution orally according to your doctor**.

It is possible that the recent mental stress has been too much, resulting in ideology being prone to trance and the need to relax appropriately.

Sudden loss of consciousness, that is, if the person faints, then he must be sick, and as for what kind of illness he has, he has to go to the hospital for examination.

Sudden loss of consciousness can be caused by many causes, but the most common is caused by ischemia or oxygen to the brain.

If a person suddenly loses consciousness, it may be that something is wrong with the brain, a cognitive impairment, or the person is very frightened.
