Causes of autism in children, how autism is caused in children

1. Genetic factors: Among the 20% of autistic patients, his family can find patients with mental retardation, language retardation and similar autism. In addition, about 10% of boys with autism have chromosomal fragility.

2. Viral infection during pregnancy: Women may suffer from measles or epidemic virus infection during pregnancy, which can damage the brain development of the fetus and lead to autism.

3. Metabolic diseases: congenital metabolic disorders such as benzoneuria cause dysfunction and disorder of brain cells, which will affect the function of cranial nerve information transmission and cause autism.

4. Brain injury: Brain underdevelopment caused by factors such as embarrassing miscarriage during pregnancy, premature birth, dystocia, neonatal brain injury during childbirth, and brain damage caused by encephalitis, meningitis and other diseases in infancy may increase the chance of autism.

1. Viral infections during pregnancy Women may suffer from viral infections such as rubella or epidemic during pregnancy, which can damage the brain development of the fetus and lead to autism. 2. Genetic factors Experts said that among 20% of autistic patients, his family can find people with mental deficiency, language retardation and similar autism.

In addition, about 10% of boys with autism have X fragility. 3. Metabolic diseases such as benzoneuria and other congenital metabolic disorders cause dysfunction and disorders of brain cells, which will affect the function of brain nerve information transmission and cause autism. 4. Brain injury includes cerebral dysplasia caused by factors such as embarrassing miscarriage during pregnancy, premature birth, dystocia, neonatal brain injury during childbirth, and brain injury caused by diseases such as encephalitis and meningitis in infancy, all of which may increase the chance of autism.

5. Nervous family atmosphere makes children feel cold Experts believe that children suffering from autism are related to parents' nervous work, lack of time to accompany their children, or impatience and impatience with children.

There are many reasons for this. Autism is a developmental disorder caused by a neurological disorder with symptoms such as abnormal social skills, communication skills, interests and behavioural patterns. Autism is a pervasive developmental disorder characterized by severe, widespread social interactions and impairment of communication skills, as well as stereotyped behaviors, interests, and activities

Autism is a medical term, also known as autism, that is classified as a developmental disorder due to a neurological disorder whose symptoms include abnormal social skills, communication skills, interests, and behavior patterns. Autism is a pervasive developmental disorder characterized by severe, widespread impairment of social interactions and communication skills, as well as stereotyped behaviors, interests, and activities** unknown, and may be related to genetic brain organic lesions, psychosocial factors, etc.

Autism in children is a syndrome caused by brain, nerve and genetic lesions that is becoming more and more common in modern society. Symptoms are characterized by impaired social and verbal communication, as well as abnormalities in interests and behaviors. The incidence of autism is about 5 per 10,000, and it is estimated that there are about 500,000 autism in China's current total population.

There is a significant difference in the incidence of this disease between men and women, and the ratio of male to female prevalence in China is 4:1

Autistic people do not communicate with others since childhood, their interests and hobbies are very limited, and they have some very repetitive and stereotyped behavior patterns. They often have some emotional problems. They are seen in our eyes as patients with depression and bipolar disorder, mainly manifested by not being interested in anything and thus isolating themselves at home.

Hello, happy to answer for you. There are many causes of autism or autism, the first is brain damage caused by a variety of brain factors and diseases; The second is that the pregnant mother is infected by some viruses during pregnancy, which will also affect the baby in the womb; The third is genetic factors, 20% of children with autism are affected by genetic factors.

Autism**:

1. Heredity: The role of genetic factors in autism has become clear, but the specific inheritance mode is still unknown.

2. Perinatal factors: There are more complications in the perinatal period, such as birth trauma and intrauterine asphyxia, than in the normal control group.

3. Abnormal immune system: the number of T lymphocytes is reduced, the number of helper T cells and B cells is reduced, the inhibition-induced T cell deficiency is reduced, and the activity of natural killer cells is reduced.

4. Neuroendocrine and neurotransmitters: related to the dysfunction of a variety of neuroendocrine and neurotransmitters.

5. Family factors: In order to make a living, many parents neglect to take care of their children and rarely accompany their children to grow up.

1. Heredity, in the family of the affected child, autism and language disorder patients will increase significantly compared with the normal population, and even the risk of autism in siblings is more than 50 times higher than that of the general group, and has the characteristics of more males than females in the patient and interactive behavior with twins, so parents should pay more attention to premarital examinations to reduce the possibility of their children getting sick.

2. In terms of immunity, in the population of autistic patients, most children have a gradual decrease in the number of T lymphocytes, helper T cells and B cells in autoimmunity, which induces the deficiency of suppressor T cells and the decrease in the activity of natural killer cells in the body, that is, autism is likely to be an autoimmune disease.

3. Imaging studies, in the field of structural brain imaging technology, researchers found that the total brain volume and left and right ventricle volume of children with autism were significantly larger than those of normal infants, while the volume of the brainstem and right anterior cingulate gyrus was significantly reduced. All of these factors are likely to cause the child to be less intelligent than the average child.

4. Perinatal factors, such as children with autism who have various complications in the perinatal period, such as intrauterine asphyxia and birth trauma, are significantly higher than those in the normal control group. Generally speaking, most children younger than five years old have the corresponding ** diagnosis of brain retardation, such as prenatal or intrapartum brain injury, symptoms are present at birth, and if postpartum, symptoms appear after a period of normal development.

5. In terms of biochemical research, experts found that excessive opioid content in the brain of patients was related to loneliness, emotional numbness and difficulty in establishing emotional connections, and the level of plasma endorphins was related to the severity of stereotyped movements. Therefore, the symptoms of autistic patients are likely to be related to some indicators in the body that are different from normal levels.

Autism in children.

Autistic children have a romantic name, Star Child. They are children from the stars, talking to the world in the way of the stars. It's not that they don't understand our world, it's just that we don't understand them. So, what exactly is autism in children?

Childhood autism is a subtype of pervasive developmental disorder, which is more common in males and begins in infancy and early childhood, and is mainly manifested by varying degrees of speech development disorders, interpersonal communication disorders, narrow interests and stereotyped behaviors. About 3 to 4 patients have significant mental retardation, and some of the children have better abilities in some way in the context of general mental retardation. The prevalence of the disease is 340,000.

However, in recent years, an increasing trend has been reported, and according to the National Institutes of Health's Institute of Mental Health (NIMH), the prevalence of autism in the United States is 1 2. There is no national survey data on autism in China, and only some areas have made relevant reports, such as the report in 2010, the prevalence rate in Guangdong is as high as in Shenzhen.

Autism may be related to:

1.Heredity. The role of genetic factors in autism is well understood, but the exact mode of inheritance is still unknown.

2.Perinatal factors. There were more complications in the perinatal period, such as birth trauma and intrauterine asphyxia, than in the normal control group.

3.Abnormalities of the immune system. It was found that the number of T lymphocytes decreased, the number of helper T cells and B cells decreased, the inhibition-induced T cell deficiency decreased, and the activity of natural killer cells decreased.

4.Neuroendocrine and neurotransmitters. Associated with dysfunction of multiple neuroendocrine and neurotransmitters.

Studies have found that monoamine systems such as serotonin (5-HT) and catecholamines are underdeveloped in patients with autism, and the pineal-hypothalamus-pituitary-adrenal axis is abnormal, resulting in an increase in 5-HT, endorphins, and decreased adrenocorticotropic hormone (ACTH) secretion.

Hope it helps.

Autism is a disease that occurs in individuals with genetic predisposition under the action of specific environmental factors, and is the result of the combined action of genetic factors and environmental factors.

Autism is now recognized as the predominant cause of multiple genes and is environmentally predisposed (e.g., domestic violence), one of the evidences is that the homozygotic twins have a 60% homopathopathic rate and a fraternal twin homopathopathy rate is zero.

1. Genetic factors: From the study of families and spasms, it is found that about 10% to 20% of the siblings of autistic people may have a slight tendency to autism.

2. Infection: Women may suffer from autism due to German measles or rubella during pregnancy, which will damage the brain development of the fetus, in addition, metabolic diseases will also cause brain cell dysfunction and filial piety, affecting the function of brain nerve transmission, thus causing autism.

Factors such as atraumatic miscarriage during pregnancy may increase the risk of developing autism, such as underdeveloped infant brain, premature birth, difficult birth, neonatal brain injury, and brain damage caused by diseases such as encephalitis and meningitis in infancy.

There are a variety of reasons that can cause a child to develop autism, including genetics, brain injury, external environment, and viral infections during pregnancy.

1.Genetics: Studies have shown that about 20% of children with autism are due to genetic factors, and some studies have found that male children are more likely to develop autism. However, it is not clear what gene causes it.

2.Brain injury: When a child has risk factors such as dystocia, meningitis or trauma, the patient's brain damage can lead to autism.

3.In terms of external environment: If the child is in a bad living environment, the physical, mental and mental effects may be negatively affected, and it will lead to autism over time.

4.Pregnant women who have had a viral infection during pregnancy: Studies have shown that a pregnant woman who has a viral infection during pregnancy may affect the brain development of the fetus, which can lead to the development of autism.

If the child is diagnosed with autism, it is recommended that parents take the child to receive formal ** and ** training as soon as possible to reduce the damage to social functioning.

It may be because of the disorder in the development of the child's brain and nervous system, or it may be that parents are too indifferent to their children in daily life, and when the child encounters problems, they do not help the child solve the problem in time, and the relationship between parents and children is also very rusty, and parents often cannot give their children a sense of security.

It may be because parents do not understand their children, or because parents do not communicate with their children much, or because children themselves have no friends and are self-isolated. The child has some questions in his mind. There is also a problem with the parenting style, which is why the child has autism.

Most of them may be due to genetic inheritance, environmental influences, abnormalities in the body's immune system, insufficient care for the child, unfair treatment of the child or the reluctance of parents to communicate with the child, resulting in the child's autism.

Family genetics and autism are also related to a certain extent, the child is surrounded by a relatively lonely environment for a long time, less communication with parents, and the brain is damaged, resulting in insensitivity.

It may be caused by family education, so that the child has a very serious autism, or it may be that the parent's personality is very introverted. Don't like to talk.

There are many reasons for autism, in addition to developing good habits, it is also necessary to reasonably plan physical examinations, so as to achieve early detection and early **, once diagnosed with autism, it must be early **, so as not to make autism more serious. Professional autism** includes children's language development, behavior control, individual training, sensory integration training, parental mutual listening classes, etc., to help children live independently and integrate into society.

It's as if autism is congenital and can't**. Only through the improvement of training can children take care of themselves and integrate into society.

At present, there is no medical conclusion on the cause of autism, but at present, more and more children are showing autism, and many researchers suspect that autism is controlled by the environment and then triggered by environmental factors. Although the role of environmental factors is still inconclusive, experts have analyzed that the following reasons are the main causes of autism in Tianjin.

1. Brain injury: including the underdevelopment of the baby's brain caused by factors such as embarrassing miscarriage during pregnancy, as well as premature birth and dystocia during childbirth, may increase the chance of autism.

2. Viral infection during pregnancy: Measles or epidemic virus infection during pregnancy may lead to autism in infants.

3. Genetic factors: Among 20% of autistic people, his family can find people with mental deficiency, language development delay and similar autism.

4. Metabolic diseases: congenital metabolic disorders, resulting in dysfunction and disorders of brain cells, affecting the function of brain nerve information transmission, and causing autism.
