How can I tell if my baby is deaf and dumb?

You can talk to the baby, see the baby's reaction, if the baby does not respond to some sounds, the baby is likely to be deaf, you can watch the baby cry when the sound, if the baby often does not cry, it is likely to be dumb.

You can call the baby's name, interact with the baby, or use some techniques to contact the baby, which can effectively determine whether the baby is deaf and dumb.

You can check your child's hearing, call your child from different angles, and observe your child's expression, so that you can make a good judgment.

It is mainly to observe the degree of its response to sound, such as suddenly using a sound toy to attract the attention of the infant and toddler, if the baby's eyes can follow the sound toy to find the sound source, it proves that there is hearing, if the baby puts a sound toy next to him, he does not react, this situation proves that there is a hearing impairment. Severe deafness on both sides, unable to hear normal sounds, and therefore unresponsive to sounds. Some have residual hearing or can hear whistles, thunder, cannons and other sounds, although they cannot speak, but the sound of crying and laughing is normal.

Deafness in early childhood is sometimes difficult to identify, and the younger the age, the greater the difficulty. The main symptom of deaf children is deafness, but many deaf children still have some residual hearing and can respond to external sounds. Therefore, it is often found that deafness is not spoken when it is still impossible to speak.

It is mainly to observe the baby's response to sound, such as using sound toys to attract the attention of infants and young children, if the eyes of infants and young children can follow the sound toys to find the sound source, it proves that there is hearing, if there is no response to the sound toys next to infants and young children, it proves that there is a hearing disorder, so that it can not imitate adults normally, thus causing language development disorders, and will be accompanied by language development delay, which will lead to deafness.

The early symptoms of deaf-mute children are mainly manifested in the inability to hear ordinary sounds, so they do not respond to sounds. Generally, it is difficult to identify the capacity in early childhood, because the younger the age, the greater the difficulty, and the deafness and mute in early childhood are sometimes difficult to identify, and the younger the age, the greater the difficulty. Generally, when the child is two or three years old, he can go to the hospital for relevant examinations and then make a diagnosis.

Genetic elements. If the allele is inherited from the deafness to the offspring, or if the gene is mutated during fetal developmentIt is likely to cause abnormal development of the eardrum or metabolic disorders, which in turn can lead to hearing loss. In addition, hypoplasia of the external auditory canal and in the ear is likely to cause conductive hearing loss, while dysplasia of the ear canal is likely to cause sensorineural hearing loss.

It should be noted that the inheritance mode of congenital hereditary deafness is likely to be autosomal dominant gene inheritance, autosomal recessive gene inheritance, and companion hereditary deafness.

Acquired elements. It is very likely to be related to the occurrence of infection, poisoning, trauma and other related to the pregnant mother during pregnancy or childbirth. The causes of deafness are divided into two types: congenital and acquired, congenital deafness:

It is to emphasize the existing hearing impairment after birth. The reason may be that the auditory system of the child is underdeveloped or does not grow and develop during the embryonic period of the child. This is often accompanied by hypoplasia of the head, face, or other locations and is genetically impeded.

Patients are often found to have ear deformities after birth, such as microtia, absent ear rings, and atresia of the external auditory canal.

The root cause of congenital deafness is that the pregnant mother was treated by virus infection and ototoxic drugs during the embryonic period, which affected the fetal baby's hearing system system software from the ear and caused congenital deafness. Acquired deafness: It is a school that emphasizes that there is no problem with the human organs of the auditory system at birth, and then due to various reasons, English hearing is harmed, and then it cannot hear others or although it has basically learned some language expressions, but it is slowly forgotten because of the long-term lack of deafness, and finally the formation of a deaf-mute school.

During pregnancy, the mother used ototoxic drugs such as penicillin and quinine, which can be carried out in the fetus according to the embryo, causing the fetus to be poisoned by the brain nerves and causing deafness。If the mother is exposed to deep anesthetics during pregnancy, it can also cause fetal hearing hazards. Illness Hazards:

If one of the parents is suffering from sexually transmitted diseases, such as non-gonorrhea and syphilis infection, it can cause congenital deafness in children. The mother suffers from urticaria and toxoplasmosis infection within 3 months of pregnancy, and the viral infection can pose a threat to the fetus through the embryo, resulting in underdevelopment of the ear canal and deafness. Newborns weighing < 1,500 grams at birth, suffering from hyperbilirubinemia, severe ventricular breath during delivery, and purulent meningitis are all likely to cause deafness.

Mainly genetic factors, pregnancy factors, and perinatal factors will lead to the phenomenon of congenital deafness and mute in the baby; Chromosomal abnormalities, autosomal recessive inheritance, pregnant women infected with viruses during pregnancy, pregnant women unable to live during pregnancy, pregnant women abusing drugs during pregnancy, pregnant women with gestational hypertension, these factors can cause the baby to be born deaf and dumb.

I think this situation may be related to congenital factors, genetic factors, or it may be caused by pregnancy. I think it may be due to genetic factors or drugs that cause this to happen, and it is recommended to take the baby to the hospital for a detailed examination as soon as possible.

It is very likely that the baby is not fully developed when it is developing in the mother's womb; Genetics, infections in pregnant women, stunted growth of the baby, damage from medications, premature birth or difficult birth.

This is due to the fact that the baby is not fully developed when he is in the body; It may be due to genetic factors, if the deafness gene in the Qing Dynasty is obvious, if it is a letter, then it will be passed on to their offspring, and there may be some chromosomal abnormalities, and then the deafness will be caused.

Deaf-mute children usually have a certain cause, so how are deaf-mute children caused?

The causes of deafness are divided into congenital and acquired, congenital deafness: refers to hearing impairment that is present after birth. The reason may be that the child's hearing organs are underdeveloped or not developed during the maternal embryonic period.

This is often accompanied by developmental deformities of the head, face, or other parts of the body, and is associated with genetics. Children are often found to have ear deformities such as microtia, absent auricle, and atresia of the external auditory canal after birth. Congenital deafness occurs due to the maternal infection of the fetus during the embryonic period due to viral infection and ototoxic drugs**, which affect the fetal auditory system and cause congenital deafness.

Acquired deafness: It refers to the fact that there is no problem with the hearing organ at birth, and then the hearing is impaired due to various reasons, so that it cannot hear others or although it has initially learned some language, it is gradually forgotten due to long-term use of deafness, and finally becomes deaf and dumb. The causes of acquired deafness include damage from ototoxic drugs, trauma, infectious deafness, etc.

Deaf-mute children may not be noticed by their families at the beginning, so what are the early manifestations of deaf-mute children?

The main manifestation of neonatal deafness is hearing impairment. Generally, when the baby hears the sound, he will have an alarm reaction. In contrast, deaf babies do not respond to alarms.

Ten deaf and nine dumb, test its hearing, such as clapping hands behind the back, putting ** or shaking the bell, to see if the baby has blinking, shaking or crying and other reactions. If your baby is unaware of audio interference, you need to go to the hospital as soon as possible to have his hearing tested with a brainstem potential so that he can take action as soon as possible.

In fact, it is more difficult to identify the deafness and mute of babies in early childhood, because the baby's age is too young. Generally, the main symptom of deafness and mute is deafness, but many children have a certain residual hearing and can respond to external sounds. It is recommended to take the baby to a regular pediatric hospital in time for further examination to see the cause of hearing loss, and to carry out targeted ** according to different **.

After the diagnosis of the condition, it is necessary to carry out corresponding medical intervention and treatment in a timely manner.

Newborns can go for a hearing test; In addition, you can also shake the rattle at home 5 cm away from the baby's ear, before the child is not allowed to see, if the baby stops or reduces physical activity, it means that his hearing is normal, otherwise he should go to the hospital in time for diagnosis. Under normal circumstances, when a three-month-old baby suddenly hears a sound above 60 decibels, he will shake his whole body, clench his hands into fists, blink and other movements; 4-6 months old, responds to sounds, can recognize the mother's voice, and the child's head will turn to the source of the sound; At 7-9 months, they can actively turn their faces in the direction of the sound source, that is, they have the ability to identify the direction of the sound.

Deafness and dumbness means that the mouth cannot speak, and the ears cannot hear. The most common cause of deafness and mute in children is the loss of hearing impairment or loss of speech.

There are four factors that cause deafness and muteness: (1) Congenital factors. Genetic causes, such as rubella during pregnancy, taking medications, etc.

2) Acquired factors. It is caused by birth trauma, dystocia, neonatal hypoxia, premature infants, low neonatal weight (less than 1500 grams), as well as infantile meningitis, encephalitis, facial deformities, etc.

3) Drug factors. Common drugs are gentamicin, streptomycin, neomycin, etc.

Regardless of the cause of hearing impairment, children can lose the sense of sound, learn to pronounce, and learn language, resulting in muteness.

Normally, a 20-week-old child already responds to sounds; 1 Different phonemes can be distinguished at 3 months; Able to learn pronunciation at 10 months; When he is 1 year old, he will be called "Dad, Mom"; At the age of 2, he can say two-word sentences, such as "mine", etc. It can be seen that the enlightening and alluring effect of hearing function on speech function is very huge. In addition, babies will also imitate pronunciation by looking at other people's mouths.

If the baby does not respond normally to external sounds, does not wake up when there is a loud noise, or is slow to learn to speak, it should be examined and treated as soon as possible.

According to incomplete statistics, about 75% of deaf-mute children in deaf-mute schools are caused by the use of deaf-causing drugs, and their hearing recovery is generally difficult.

4) Diseases of the ear itself. Otitis media is more common in childhood and can damage hearing if left unchecked. After tympanic membrane perforation, if the perforation is large, tympanic membrane repair or tympanoplasty can be used to reconstruct or restore hearing.

Sensorineural deafness is called sensory deafness caused by measles and rubella and cochlear damage to the inner ear, which eventually leads to deafness. This type of deafness damages the hair cells involved in hearing in the inner ear's Corti's apparatus, and once damaged, the hearing cells cannot be restored. The first to be damaged is high-frequency hearing, with a damage rate of 10% to 20%.

Because the self-perceived symptoms of hearing loss in the inner ear are not obvious, it often fails to attract the attention of the patient, resulting in deafness.

For deaf-mute children, it should be done as soon as possible. Children with some residual hearing can try to wear hearing aids and be given appropriate hearing and language training, so that they can gain some conversation skills.

Total deafness, i.e., bone conduction hearing loss of more than 100 decibels, can be expected to return to the sound world through the installation of electronic cochlear implants. At present, the world's multi-lead programmable cochlear implants have been able to enable some patients with total deafness to reach the level of independent answering**.
