Is ADHD hereditary Is ADHD innate?

Is ADHD hereditary? This is a problem that many parents and friends who had ADHD when they were children are very worried, and they are worried that their children will have ADHD as they did when they were young, is this really the case? In order to help you have a deeper understanding of the genetics of ADHD, let's follow along to learn about it, which is as follows:

Regarding the genetic problem of ADHD, a large number of research data at home and abroad show that heredity is one of the main problems of ADHD. As early as the 70s of the 20th century, it was found that 40% of children with ADHD also had ADHD in their parents, that is, familial clustering. Each parent provides 23 chromosomes, which they combine into 23 pairs.

How can these little 23 chromosomes carry all the information that parents have? The birth of life is a mysterious process.

According to the 1985 Chinese Journal of Neuropsychiatry, 36.4% of parents were naughty and hyperactive when they were young, and their siblings had similar symptoms, and their relatives had neuroses, severe psychosis or personality disorders. In 1975, "Foreign Medicine" (Pediatric Division) reported that when studying the family history of 18 cases of ADHD, it was found that the incidence of homogeneous siblings of children with ADHD was higher than that of half-siblings, who in turn were higher than the general population; In 1982, the Chinese Journal of Neuropsychiatric Diseases reported that the study of ADHD twins showed that 7 pairs of monozygotic twins had the same morbidity rate, and 3 pairs of fraternal twins had the same pathopathy rate; In 1981, the Chinese Journal of Neuropsychiatric Diseases reported that there was a family history of ADHD in 700 cases, and 9 pairs of twins had the same disease.

The above data fully shows that genetic factors are closely related to ADHD. As for the way ADHD is inherited, there is still disagreement. In polygenic genetic diseases, the susceptibility is affected by both genetic basis and environmental factors, and the higher the heritability, the greater the role of genetic basis in determining disease susceptibility. Otherwise, it means that environmental factors play a leading role.

Some people have surveyed that the heritability of ADHD is 70% (higher), suggesting that genetic factors play an important role in ADHD, but the influence of environmental factors on the onset of ADHD cannot be ignored. In conclusion, genetic predisposition is the basis for the onset of the disease, and brain injury or poor environmental education from any cause before or after birth plays an important role in precipitating or exacerbating symptoms.

There is currently no unified view of how ADHD is inherited. For a person's growth, genetics plays a role in 3 points, and the acquired environment plays a role in 7 points. Children with multiple symptoms can be developed in a favorable direction through the intervention of the acquired environment.

I believe that through the above description, we have understood that ADHD is hereditary, but it does not mean that there is no way to cure it, any hereditary disease can be improved through acquired ** and nursing **, I hope that parents and friends do not give up on ADHD **.

ADHD has a genetic link. Several studies on family sexual history in the 90s of the 20th century found that 30%-40% of children with ADHD have the disease in their families. Other familial studies have found that children with ADHD often have specific dyslexia in their families.

Researchers have discovered a type of gene called the dopamine receptor DRDC, and 40 percent of all people found to have this variant suffer from attention deficit and hyperactivity. Although the numbers are not absolute, for families where neither spouse has a family history of ADHD, the probability of having a child is 2% to 3%. When family members counsel about the risk of having another child, they receive empirical data based on previous studies.

Summarizing numerous studies, the risk of having another child ranges from 16% to 25%.

Is it possible that ADHD in my child is genetic? A study published in the journal Nature Genomics suggests that ADHD may be hereditary. Scientists have identified more than 300 genetic variants in ADHD, with a probability of increasing the variant by about 19%.

The findings, from the State University of New York Upstate Medical University, refute the narrative that ADHD causes undesirable behavior. In the first study of its kind, researchers analyzed the genetic data of 55,374 people taken from a global database, of whom 20,183 were diagnosed with ADHD.

A total of 304 mutations were found in 12 genes, which could be identified as having a particular impact on mental disorders. Some of these gene variants also overlap with genes that cause 44 other traits, including severe depression, anorexia nervosa, obesity, insomnia, and even smoking. These genetic mutations are thought to affect the patient's central nervous system, which in turn affects brain development and nerve cell signaling function.

The study also demonstrated that impulsive sexual behaviors such as sleep disturbances, binge eating, and smoking can also cause ADHD. ADHD affects 5% of adolescents and adults worldwide. Boys are about four times more likely to suffer than girls.

Previous studies have investigated the influence of genes on people developing ADHD, pointing out that environmental factors are also involved, such as improper parental upbringing.

Is it possible that ADHD in my child is genetic? ADHD is more pronounced in early childhood and may become more pronounced as the child grows older, and symptoms may include persistent restlessness. This is a disease that cannot be abandoned, but taking medication and taking a two-pronged approach can alleviate the symptoms.

Hello, glad for your question :

Attention deficit hyperactivity disorder (ADHD) is a common type of psychological disorder in childhood. Presents with inattention and attention spans disproportionate to age and developmental level, hyperactivity, and impulsivity, often accompanied by learning difficulties, conduct disorders, and maladjustment.

ADHD** needs professional targeting**, it is recommended to go to a regular specialist hospital.

How is ADHD**:

1. Education and guidance. For school-age children, tutoring is mainly in the form of education. Parents or teachers should not be too harsh on the child, as this will make the child more stressed.

2. Formulate a code of conduct. In ordinary life, we should point out some reasonable norms to children, let children do things by themselves, and let children have a sense of achievement. Give appropriate rewards.

3. Psychology**. Parents and teachers communicate more, put forward some education methods in a targeted manner, grasp the psychological characteristics of children, and carry out timely, fair and patient education.

4. Drug control. Go to a regular hospital and ask the doctor to give medication advice.

Hope it helps.

ADHD in children is a common problem of abnormal behavior in children, which is mainly manifested as difficulty concentrating, short attention, excessive activities, and impulsive emotions, which affect academic performance.

** for ADHD in children

1. Genetic causes, genetic factors are one of the main causes of ADHD in children, ADHD is a hereditary disease related to neurodevelopment;

2. Organic causes of the brain, if the mother has been infected during pregnancy, has been exposed to toxic substances, malnutrition of pregnant women, smoking, drinking alcohol and other reasons will affect the fetus, as well as abnormal delivery, low birth weight of children, and brain infection within 1-2 years after birth, or brain trauma will lead to abnormal neurological development of children.

3. The central neurotransmitters are abnormal, the norepinephrone function of children with ADHD is insufficient, and the dopamine function is insufficient, etc., these neurotransmitters can activate the cerebral cortex or strengthen social behavior. This can cause ADHD in children.

4. Caused by psychosocial factors, a bad family environment and social environment will increase the risk of ADHD in children, such as children in the family parents have a bad relationship, the spirit is often spent in tension, depression, fear, prone to excessive impulsive behavior, inattention, emotional instability.

5. For other reasons, excessive intake of lead in children can also cause ADHD in children.

Probably not, every child is different, some are active, some are very quiet.

ADHD is not only innate, but also has other causes, which are roughly referred to as follows.

Genetic factors (20%):

Current studies have shown that the disorder is related to genetic factors, the heritability is, the mode of inheritance is not clear, and it may be polygenic inheritance. Molecular genetic studies have shown that the disorder is associated with polymorphisms in the dopamine receptor gene.

Neurophysiological factors (25%):

Children with this disorder have a high rate of EEG abnormalities, mainly due to increased slow-wave activity. EEG power spectrum analysis showed that the slow wave power increased, the wave power decreased, and the average frequency decreased. Suggests that children with this disorder have delayed central nervous system maturation or cerebral cortex hypoarousal.

Minor brain damage (15%):

Minor maternal brain injury during pregnancy, perinatal period, and after birth may be the cause of the disorder in some children, but no brain injury is present in all children with the disorder, not all children with the disorder have the disorder, and many have no evidence of brain injury.

Neuroanatomical factors (8%):

Magnetic resonance imaging studies have reported a decrease in the volume of the corpus callosum and caudate nucleus in children with this disorder, and functional magnetic resonance imaging studies have also reported a decrease in the metabolism of the caudate nucleus, frontal region, and anterior cingulate gyrus in children with this disorder.

Psychosocial factors (10%):

Adverse social and family environments, such as economic poverty, parental breakdown, and inappropriate educational practices, can increase the risk of children suffering from this disorder.

Other factors (15%):

The disorder may be associated with zinc, iron deficiency, and increased blood lead. Cola, coffee, and food additives may increase the risk of the disorder in children.

ADHD is hereditary. ADHD exudation** is caused by pediatric white matter hypoplasia (retardation), and ADHD in children has two main symptoms, namely attention impairment and hyperactivity. Attention disorders have long been recognized as one of the most prominent manifestations of ADHD in children.

ADHD is manifested as not being able to listen carefully to the teacher's lectures in class, being easily distracted by subtle distractions from the outside world, not being able to concentrate on homework, doing things for fun, not being able to do things consistently, not being able to complete them according to rules and requirements, etc.

The pathogenesis of ADHD is not clear, and it is currently believed that it is caused by the interaction of multiple factors. Heredity is one of the main causes of ADHD. ADHD can be inherited.

As early as the 70s of the 20th century, it was found that 40% of the parents of children with ADHD also have ADHD, that is, familial clustering. Heredity accounts for a large proportion of ADHD**, with a 25% risk for first-degree relatives, a 79% chance for identical twins, and a 32% risk for fraternal twins.

Yes, ADHD is indeed a genetically predisposed condition; There are many reasons why children with ADHD will be affected, and if the parents have ADHD, the child's tendency to suffer from ADHD will increase significantly.

Yes, the probability of heredity is about 60-70%, which is mainly related to the imbalance of neurotransmitters in the brain.

ADHD is genetic.

Genetic causes of ADHD account for about 76 percent. In addition to genetics, it may also be related to neurochemical transmitter imbalances in the brain, familial and psychosocial factors. The disease usually manifests itself as symptoms such as inattention, short attention span, and impulsiveness.
