What causes temporary amnesia?

What is the cause of short-term amnesia?

Instant memory is a type of memory. It is a sensory registration and a direct impression of external information. Psychological research has found that during the period of instant memory, the brain does not store the memory, so it fades quickly after 0.25---2 seconds.

Selective amnesia is when a person forgets some things, people or things that he does not want to remember or escapes after being exposed to external attacks or brain collisions.

There are two types of temporary amnesia:

① Temporary amnesia is due to the brain being violently impacted by the outside world, causing hemocephalus, and the blood clots suppress some memory nerves, causing amnesia. Once the bleeding is released after surgery, the memory will be restored.

②Temporary amnesia is usually caused by sudden and temporary changes in personal consciousness, identity or behavioral coordination when a person is subjected to severe social and psychological pressure, which can easily lead to physical and mental collapse. , if the consciousness changes and the person cannot remember important personal events, psychogenic amnesia will occur.

Supplement: If you are too nervous, you will also suffer temporary amnesia. For example, when performing on stage and suddenly forgetting lyrics or lines, this is also temporary amnesia. It’s almost the same as the second temporary amnesia. The bioelectrical signals between each functional area are too strong during excitement, causing mutual interference between the areas, resulting in transient loss of function! This is normal. Temporary amnesia is caused by short-term memory. The brain has not really received the information, so this situation occurs. What is the cause of short-term amnesia

Selective amnesia. The brains of people with this kind of amnesia will act like filter paper, automatically filtering out things they no longer want to remember and only remembering things they are willing to remember.

Indirect amnesia means that the events of the day are forgotten after 1, 2 or 3 days? You can only gather enough energy for 20 minutes, and you won’t be able to do it after 20 minutes.

Most of the causes of amnesia are due to too many things in work and study, too full schedule, too much physical fatigue, mental depression, anxiety, etc. The following factors are also important causes of memory loss:

< p> 1. Lack of nutrients, especially the lack of B vitamins and amino acids, causes memory loss.

2. Allergies, candidiasis, mental stress, brain tumors, diabetes, alcoholism, hypothyroidism, neurosyphilis, poor blood circulation in the brain, etc. may affect memory.

3. Hypoglycemia can cause memory loss. Changes in blood sugar levels can affect brain function and memory.

4. Patients with cervical spondylosis may experience symptoms such as memory loss, inability to concentrate, frequent dizziness, dizziness, or headaches.

5. Air pollution affects memory. The use of computers, air conditioners and other electrical appliances will significantly reduce negative ions in the air; harmful gases in furniture and decorative materials can cause dizziness, fatigue, memory loss, physical decline, and even disease.

6. Using computers for a long time can also cause memory loss and hinder the development of intelligence.

Research from the British Psychological Association believes: "If you treat the computer as an external memory, your daily memory will be threatened."

7. People with long-term drinking habits will suffer from memory loss. Because alcohol can cause vitamin B deficiency.

8. Being overweight can damage your memory. People who are overweight may experience slower cognitive decline, slower movement, and more severe pain.

9. A high-fat diet will not only increase the risk of cardiovascular and cerebrovascular diseases, but may also damage memory.

10. Improper weight loss will lead to memory loss. The fat content in brain cells is as high as 60%, which is a necessary nutrient to maintain the normal work of the brain.

Red Alert

If severe memory impairment suddenly occurs, with obvious fluctuations, good and bad, this is often caused by cerebral arteriosclerosis. Patients with cerebral arteriosclerosis The blood supply to the brain is often insufficient due to cerebral vasospasm, which affects brain function and causes memory loss. Cerebral arteriosclerosis should be actively treated.

If you don’t even know which direction your home door opens, this may be a sign of stroke or Parkinson’s disease. You should immediately go to the neurology department of the hospital for a comprehensive examination to make a clear diagnosis and provide corresponding treatment.

Temporary amnesia

Generally speaking, the onset of temporary amnesia is usually the same as amnesia in the elderly. The older you are, the higher the likelihood of it happening. Clinically, most patients with temporary amnesia will regain their memory within 24 to 48 hours after the cause is found and treated.

Suffering from temporary amnesia, a sudden loss of memory, is usually related to a problem with the patient's brain function. It is like a computer suddenly crashing and unable to operate normally. Patients usually suffer from 3 conditions: occur, including temporary strokes, epileptic seizures and migraines.

Generally, patients with temporary amnesia only have problems with their memory during a certain period of time. Their basic skills and knowledge are usually not affected, and there are no problems with their behavior itself, as long as they Once the cause is identified and treated, most of the symptoms will not reoccur.

Patients with temporary amnesia caused by temporary stroke usually also represent the precursor of the patient's imminent stroke. Clinically, it can be controlled by administering medication and reminding the patient to adjust his/her daily routine and eating habits. , Delay the occurrence of stroke. What causes people to temporarily lose their memory?

The impact of diabetes on the central nervous system has attracted widespread attention. The concept of diabetic encephalopathy has been gradually enriched and improved. Although there is currently no standard definition, it can basically be understood as: cognitive impairment and neurophysiological and structural changes in the brain caused by diabetes.

First, insufficient insulin secretion leads to hyperglycemia. Chronic hyperglycemia can cause the capillary basement membrane to thicken and narrow the lumen. Coupled with the disorder of lipid metabolism in diabetic patients, blood viscosity increases, blood flow slows down, and cerebral blood flow decreases. Studies have confirmed that reduced cerebral blood flow can impede the brain's understanding, processing, and integration of information, reduce cognitive response and processing capabilities, and ultimately lead to impairment of learning and memory functions. Hyperglycemia can accelerate the early onset of Alzheimer's disease. Epidemiological studies have shown that the risk of dementia in elderly patients with diabetes is twice as high as that in normal controls. Among them, type 2 diabetes is more closely related to Alzheimer's disease. These findings suggest that diabetic encephalopathy in many ways reflects the accelerated aging of the brain.

Secondly, hyperinsulinemia is one of the characteristics of insulin resistance in type 2 diabetes. Type 2 diabetic individuals with hyperinsulinemia and diabetic patients treated with insulin often experience hypoglycemic reactions. The drop in blood sugar will lead to a series of reactions such as the secretion of glycemic regulatory hormones and dramatic fluctuations in blood sugar levels. When blood sugar is lower than 3.0mmol/L, cognitive function damage will occur. The degree of functional damage in different areas of the brain is different, and attention and reaction speed are the most susceptible to damage. Cognitive dysfunction often appears quickly with the onset of hypoglycemia, and the recovery process is quite slow. It usually takes 40 to 90 minutes after blood sugar returns to normal to fully return to normal. Hypoglycemic sensitivity is the greatest obstacle to strict blood glucose control. The frequent occurrence of asymptomatic hypoglycemia during daily blood glucose testing suggests that the patient is developing functional impairment of hypoglycemia awareness.

In addition, hypoglycemia can also induce changes in mood, causing anxiety, depression and fear of recurrence of hypoglycemia, which in turn affects the quality of blood sugar control. Repeated episodes of severe hypoglycemia can accumulate cognitive function impairment and reduce sensitivity to hypoglycemia, resulting in chronic sequelae. What is the cause of temporary blindness?

Condition analysis: The question you asked is that you have a problem of momentary blindness, and you also have a problem of hypoglycemia. In fact, your momentary blindness is a symptom of transient ocular ischemia. The main cause is a temporary poor blood supply to the fundus, which cannot be said to have nothing to do with your hypoglycemia. But the main problem is the blood supply to the brain.

Hello, I am honored to answer your question

Why do people lose their memory?

Amnesia can be divided into psychological causes Sexual amnesia is caused by brain trauma and dissociative amnesia. Dissociative amnesia is mainly caused by the destruction of consciousness, memory, identity, or the normal integration of the environment, causing troubles in life, but these symptoms It cannot be explained by physiological factors. Patients often do not know who they are or experience that there are many "selves".

[color=Blue][b]Psychogenic amnesia symptoms: [/b][/color]

1. The patient loses memory of past experiences. The amnesia phenomenon is Caused by psychological reasons.

2. The patient's memory loss is sometimes limited to the inability to remember things during a certain period of time, that is, he only remembers old things and forgets the present.

3. Some of the memory lost by patients is limited to no memory of important things. This situation is called episodic amnesia.

4. Some patients' memory loss occurs suddenly after suffering a painful blow. After a period of time, the memory may be restored.

[b][color=Purple]Psychogenic amnesia*** has the following four types: [/color][/b]

1. Regional amnesia Symptom: The patient completely loses his memory of the circumstances within a few hours before and after certain traumatic events

2. Selective amnesia: An individual selectively remembers some things and forgets some things that happened during a certain period of time.

3. Total amnesia: refers to the individual completely forgetting his or her life background, including name, address, etc.

4. Continuous amnesia: refers to the individual forgetting the past year or date. Past experiences before the incident

The obvious symptoms of amnesia patients include loss of memory for short-term things, difficulty in verbal expression, and difficulty in understanding abstract things. They can only think about and speak, but cannot do it. wait. Show obvious tendency to forget things, repeat questions, or ask for things repeatedly, be easily agitated or become slow and uncooperative, etc. Therefore, caring for patients with amnesia not only costs a lot of money, but also consumes the caregiver's physical and mental energy for a long time, and even causes depression. It is a huge impact and burden on the family members, and it is also a major pressure on society.

The process of amnesia progresses from mild to severe

1. Mild patients: It is easy to forget what just happened, so it is difficult to learn new things. Sometimes you will lose the familiar path, and then you will be depressed, afraid to go out, and unable to properly reply or handle a lot of letters or bills. Therefore, at this time, he may still be able to go to work and get off work well, without much difference from normal people. However, if it is more serious, it will be difficult to go on business trips, travel, or plan things such as holding a banquet, and the work efficiency will be significantly degraded.

2. Moderate patients: The forgetfulness worsens, and gradually they even forget the names of old friends and things they have done before. Keep repeating one thing, or ask the same questions again and again, or always think that you have not eaten and ask your family for more. What you say to yourself will be ignored, or you will make up stories to stop others. Unable to carry out things well that I have written down and agreed to do. The behavior gradually becomes out of control, easily agitated, weird and wandering around. Clothing that is inappropriate or inappropriate or wearing the same outfit every day. Confused thinking, or delusions, fantasies, hallucinations, etc. As the symptoms continue, they will gradually become unable to bathe themselves, use toilet utensils, and lose control of bowel and bladder control.

3. Severe patients: They do not even recognize their family members and friends, and gradually lose the method of communicating with others. They will shout aimlessly and hit others, and are completely unable to take care of themselves.

Eventually, he could no longer move or swallow, and had to be carried in and out of bed by his family and fed through a gastric tube.

Dissociative amnesia is considered the most common form of dissociative disorder. The most common form of this disease is the loss of personal identity, but the memory of general information is intact. In fact, of all dissociative disorders, memory loss is the most common symptom. Dissociative amnesia affects more women than men and more young adults than older adults. The onset of amnesia in this type of case is usually sudden. The patient will be unable to recall his previous life or personality, and mainly loses "past memories", especially traumatic life events.

The behavior of dissociative wandering disorder is usually more purposeful combined with amnesia. Patients often leave their original family or job and travel to another unfamiliar place to establish another family or job. When they are found, they already have a new "self", but they cannot remember important information about their past (such as their original name, family, and job), and the new self and the old self will not interact. . This disease is rare and usually occurs after wars and major disasters. Dissociative personality disorder is the familiar multiple personality disorder. It is a chronic disease and is also considered the most serious disease among dissociative disorders.

Patients with this disease usually have more than two personalities. At different times, one personality will become the main personality, and each other will be ignored. When one personality appears, the other disappears. The two personalities have their own memories, emotions, behavior patterns, attitudes, etc., and they are usually very different, as if two souls live in the same body.

The cause of this disease is unknown, but research shows that people with antisocial personality, alcohol and drug abuse are prone to this disease. Aphantasia is a persistent or repeated perception that the self has temporarily disappeared, and feels that oneself is strange and unreal. Patients often feel like a robot, in a dream, or feel that they have left their body. This kind of The sensation makes patients uncomfortable, and they know the symptoms are not real.

There are still different opinions on the cause of dissociation disorder. As for the pathogenic mechanism, it is generally believed that it may be "dissociation of psychological functions", that is, individuals who were originally capable of self-awareness and integration, due to pressure, dissociate into various parts, causing thoughts, memories, and behaviors to Being excluded from consciousness, causing symptoms such as amnesia and personality changes.

Although the pathogenic mechanism has not yet been determined, psychological factors are generally believed to be the trigger for the disease. It is generally believed that patients may have inherent defects caused by genes and life trauma. When faced with stressful events in life, they are unable to maturely respond to them, resulting in dissociation. Treatment is usually based on psychotherapy, which includes identifying and appropriately handling stressors, moderate listening, hypnotherapy or drug-assisted interviews, and encouraging patients to overcome symptoms (such as recall).

What is the reason for frequent temporary blindness?

Suggestion: This phenomenon should be used clinically It is called melanoma fugax. Generally speaking, it is related to transient cerebral ischemia, hypotension, central retinal and branch artery spasm, and migraine. Others include excessive fatigue, hunger, and mental fatigue. It has something to do with hysteria, etc. Check your blood pressure. You won't suddenly go blind. Don't put so much pressure on yourself~ It's probably because you have been online for a long time, right? Pay attention to rest your eyes. Why do you feel dizzy when you stand up after squatting for a long time? If you squat on the ground for a little longer and suddenly stand up, you will often feel like the world is spinning and stars are appearing in your eyes. This is caused by temporary anemia in the head. When a person squats, the distribution of blood in the body is somewhat special. Firstly, the two legs are pressed very tightly, and the blood vessels are flattened, so relatively less blood reaches the lower limbs; secondly, because the head is tilted slightly forward when squatting, the blood going to the head is relatively distributed. Some. When you suddenly stand up, the blood vessels in the lower limbs suddenly release their compression, so a considerable amount of blood flows to the lower part of the body. Furthermore, blood also has a certain weight in the body. When you stand up suddenly, due to the attraction of gravity and the effect of inertia, a larger amount of blood flows to the lower part of the body, and the blood distributed to the upper body will reduce. In addition, when standing up, the head is also erect, and it is more difficult for the heart to spray blood toward the head. All of these results in a relatively reduced blood flow to the head.

The human brain is most in need of blood oxygen supply. A short-term reduction in blood supply can make people feel dizzy due to temporary cerebral anemia. In addition, due to the decrease in blood in the head, the blood supply in the eyeballs will naturally be less. In this way, dazzling and Venus-like phenomena will occur. At the same time, anemia and hypoglycemia will aggravate this phenomenon. What causes temporary blindness with glasses

What is love? The meaning of love is very broad, it can be friendship, family affection, love... Among them, perhaps the one that people are most interested in is love, right? Then I might as well talk about love. Love is the most beautiful word. How many people are pursuing it hard. Sometimes people regard love as more important than life. But what is love? How many people truly have everlasting love? How many people have been searching all their lives? Love may be the feeling of heartbeat when you fall in love at first sight, love may be the feeling of committing your body to each other, love may be the feeling of life, death and sexual intercourse... Love is a topic that cannot be said enough. When you fall in love with someone, your heart is frightened and uneasy. You don't know how the other person feels. You have to hide your feelings because you are a reserved person. Maybe your original love

was caused by insufficient blood supply. Some were caused by insufficient blood supply to the brain, or perhaps insufficient blood supply to the heart. It is not life-threatening, but it is a signal. You should pay more attention to your health in the future. Home button What is the reason for the temporary failure after restarting?

Specific reasons:

1. The home button fails due to software conflicts (the most common is the deb plug-in after jailbreaking).

2. The system executes for a long time, causing home response failure.

Solution to malfunction:

1. Open any app, press and hold the power switch for a few seconds until the instruction to slide off appears on the screen. Release the power button but do not slide it to shut down. Press and hold the Home button for a few seconds until the screen returns to the desktop state.

2. Connect the iPhone to an external power source, hold down the home button until the voice interface appears, and then remove the external power source.

Tips:

In addition, dust enters the home button. When the upper and lower contacts are separated by dust, it will malfunction. You have to press it hard. The solution to this is: flick the home button with your hand to pop out the dust inside.

If it is not a system problem or the hardware problem cannot be repaired, consider replacing the home button, purchasing a replacement yourself or solving it through after-sales service.
