Can a premature baby have less intelligence than a normal baby? Developmental delays

Generally speaking, premature infants have immature immune systems and poor resistance, and are prone to diseases in the neonatal period, the most common of which are respiratory distress syndrome, asphyxia, and infection.

Premature babies are able to catch up with normal babies within two weeks. However, some premature babies are born with low blood sugar and low blood calcium, causing febrile convulsions, resulting in brain nerve damage, thus endangering the brain development of premature babies and resulting in low intelligence. Therefore, for premature infants, it is necessary to take good care of them and check them on time to prevent higher damage to the baby.

If the premature infant is not treated before 32 weeks of pregnancy, the fetus will be born with more severe ventricular breath, and the recovery will be more suboptimal, and there is a greater probability of damage to the central nervous system, thus leading to more serious intellectual retardation. If after 32 weeks of pregnancy, premature babies who have been treated by intervention do not have a relatively serious ventricular condition and the survival rate basically reaches the level of full-term babies, then the damage to the central nervous system will be much lighter, and the probability of mental impact will be greatly reduced.

Every child's condition is different and it is not certain that they will be affected. Like my baby was born at 28 weeks, born 2 pounds and 2 taels, is a sure slap baby, when living in the incubator is also a critical notice of a big push, the doctor will talk about the situation is particularly serious, it is said that like my baby intelligence this week should be affected, my baby is more lucky, not more than 7 months will call mom, seven months will call dad, now not eleven months, to say that the parents of the big grandmother, can understand some such as a warm welcome goodbye and other words, very naughty, is a nosy woman. The doctor said that the child was definitely not stupid.

Naturally, there are some big sports that are definitely a bit outdated compared to full-term babies, after all, there are so many premature babies. Until now, doctors have not seen the state of intellectual backwardness.

The weight of the brain in premature babies is generally 370 grams during the period of term and doubles by June. Doubled again in the course of 2 years of age. At this time, the net weight of the human brain is three times that of a newborn baby at term.

In babies between zero and six months, the human brain creates 700 nerve cell connections per second. Nerve cell connections are subject to innate hazards and acquired natural environment. Especially parent-child activities with parents.

Between 6 months and 3 years old, the rate of brain development is about 80% to 90%, and the total number of axons in the child's brain will increase rapidly at this stage. It's like a small tree absorbing nutrients and slowly becoming more and more luxuriant. Therefore, the leading cadres are three years old is an important period of brain development, if their baby is a premature baby, the mother can complete the correct guidance according to this stage, the baby's intelligence will take a very big leap, and even higher than some full-term babies need to be more intelligent.

The answer to whether or not the intelligence of premature babies will be affected varies from person to person, some children may be affected, some may not be affected at all, and there are very large individual differences. Theoretically, the younger the gestational age, the more likely premature infants are to develop neurological sequelae, such as cerebral palsy.

1. Avoid strenuous exercise: in the early stage of pregnancy, when the embryo is not full-term, do not do too much exercise, especially strenuous exercise and exercise that is easy to increase abdominal pressure, although appropriate exercise is required after the second trimester, but the exercise needs to be mainly walking and yoga for pregnant women;

2. Cervical preventive cerclage: for pregnant women with a history of preterm birth or a history of late miscarriage in the last month, ultrasound examination should be performed at about 12 weeks of pregnancy to measure the length of the cervical canal, if the length of the cervical canal has been progressively shortened, cervical preventive cerclage is required, and patients who are prematurely born due to cervical insufficiency can be subjected to preventive cervical cerclage in the next pregnancy to reduce the risk of premature birth after another pregnancy;

Most of them are not, unless they are born with respiratory distress or poor development, otherwise their IQ will not be damaged. When you reach the third trimester, you should pay attention to rest, try to reduce your activities, and pay attention to nutritional supplements when preparing for pregnancy.

If it is just a simple premature infant, there will be no problem with intelligence. In the third trimester, don't eat too greasy food, don't do heavy work, don't work too hard, and go for regular prenatal checkups can avoid premature birth.

Don't like to cry

The initial stage of mental retardation in newborns is usually characterized by long sleep, inactivity, little crying, dull expression, and prolonged drooling. These are early signs of mental retardation, and mothers should be aware of them. Manifestations of mental retardation in newborns, long sleep, sleep all day, inactivity, little crying, sometimes accompanied by screaming and weak crying; The time to laugh is delayed.

Normal babies will smile at their mothers at 4 to 6 weeks after birth, while mentally handicapped children will not smile at 3 to 4 months.

Always in a daze

The expression is sluggish and expressionless, normal children can pay attention to their surroundings in a month, and mentally disabled children are not interested in people and things around them; It's late to play fingers. Normal children at 3 to 4 months of age, lying down to watch, play with their hands, while mentally handicapped children generally appear after 6 months, clumsy movements; frequent drooling and protruding tongue, which persists beyond 1 year of age; 2 Keep small toys or other objects in your mouth at the age of 3 years, while normal children do not put objects in their mouths after 1 year of age.

Poor learning ability

poor response to speech, inattention to adults and talking to him, delayed speech development; Can't count, 3 or 4 years old can't count, can't add and subtract simply; Slow development of major movements such as raising the head, turning over, sitting, standing, and walking; It has a special appearance that is different from the average child. If the above symptoms are found, the child should go to the hospital for examination and diagnosis, so that it can be detected and treated early.

Due to "congenital insufficiency", premature infants have poor thermoregulation function, immature respiratory center, and are more likely to have respiratory dysfunction, which is manifested as shallow breathing, irregular respiratory rhythm, apnea, cyanosis and other symptoms, in addition to cerebral hypoxia. In addition, alveolar lack of surfactant predisposes to the formation of hyaline membrane disease, which aggravates hypoxia. Premature infants have poor swallowing and digestion function, easy to vomit and choke on milk, which can cause aspiration pneumonia and aggravate hypoxia.

Preterm infants are undernourished.

Premature infants have imperfect liver function, which leads to the deficiency of enzymes and proteins that contribute to jaundice, so that jaundice cannot resolve quickly, and hyperbilirubinemia occurs. In addition, preterm infants with poor coagulation and hypoxia are prone to intracranial hemorrhage. Severe diseases such as apnea and aspiration pneumonia, hyaline membrane disease, hyperbilirubinemia, intracranial hemorrhage, etc.

It can lead to hypoxic necrosis of brain cells in premature infants, affecting children's intellectual development. Premature infants are also prone to hypoglycemia and hypocalcemia, causing convulsions, brain cell damage, brain development disorders, and mental retardation.

Premature infants are mentally retarded by frequent crying and sluggish reflexes, which are often the case in premature infants.

The sleeping time is particularly long, the eyes are relatively dull, not lively at all, and there are basically these manifestations; Yes, premature babies are likely to have mental retardation.

The reaction is relatively slow, the expression is more sluggish, the time to laugh is a little later, and sometimes the drooling will be drooling; Sometimes they are mentally retarded, and some are not.

If the child is born prematurely, the development is normal, the intelligence will generally not be affected, and the development may be relatively slow, as long as the baby is well cared for.

Suggestions: First, it is recommended to create a quiet and comfortable environment for the baby, do not disturb the baby, do not often hold or move him. Second, the resistance of premature babies is weak, so we must pay attention to keeping warm and not letting the baby get cold or heat.

The indoor where the baby lives must pay attention to the control of temperature and humidity, and also maintain ventilation, keep the indoor relief clean and clean, and avoid bacterial infection of the baby's health.

Preterm birth is one of the risk factors for mental retardation in children, but it is not necessary for premature infants to develop mental retardation, depending on the degree of preterm birth, the nature and severity of the disease accompanying birth, and the family environment.

In addition, whether preterm babies are actively monitored for development after birth and whether early intervention is carried out for possible developmental delays also affect the intellectual developmental outcomes of preterm infants.
