Mental deficiency is caused by many different reasons. These causes are three groups: prenatal causes, maternal causes, postnatal causes.
What are the reasons that influence the brain development of the baby on the mother’s womb?
– Feverish and infectious diseases such as rubella, syphilis
– Mother can not feed well and balanced
– Mother’s alcohol and smoking
– Material addiction
– The mother is over stressed and heavy working conditions
– Inadequate listening
– X-ray exposure
– Mother’s medication for childbearing and failed practices
– Pregnancy poisoning
It causes various disorders in the baby’s brain that is still developing in the mother’s womb.
The anomalies that occur in the development of the baby’s skull in the womb also cause mental deficiency.
The most common anomalies in the development of the skull are hydrocephalus and microcephaly.
Hydrocephalus: The head is excessively large compared to the body.
Microcephaly: The head is extremely small compared to the body. The most common chromosomal abnormality is down syndrome. Down syndromes are also referred to as “mongoloid” because of the resemblance of some physical features to mongols.
Down syndrome; chromosomal excess. In these patients, there are 3 chromosomes instead of 2 in the 21th chromosome pair. Therefore, they have 47 chromosomes instead of 46 chromosomes. For this reason, all children with Down’s syndrome are similar. Apart from these, blood disagreement is a condition that can lead to mental deficiency.
Blood disagreement; Rh-positive blood-group mother and Rh-positive blood-group father marriage; the baby’s blood group is Rh-positive. In this case, the blood of the mother who is connected to the mother’s blood circulation and which is being nourished by this way shows the mother’s blood incongruity; which can lead to various disorders in the baby’s brain.
Finally, factors such as close family marriages, soy attraction factors, mother’s age younger than 18, older than 35 years, and the fact that her father is very old also lead to mental deficiencies.
Causes of mental retardation due to birth
- Birth is inadequate and occurs under difficult conditions
- Preterm pregnancies that last from 37 weeks to 42 weeks
- Difficult and operational births
- The baby is physically damaged resulting in falls and knocks during delivery
- Infusion of light and oxygen in the cuboid to infants who are placed in a cupola
- Factors such as the anxiety of the child at the moment of birth
- Which will negatively affect both the development and the existing capacity and equipment
Can lead to various mental deficiency.
The moment of birth is anoxia; During the birth process, the baby can not get enough oxygen. This can happen for many reasons. These include; we can say that the umbilical cord wanders around the baby’s neck, abnormal and prolonged births, the child’s inversion during delivery, and the drug given to the woman at birth. Many researches have shown that long-term oxygen deficiency; which leads to brain paralysis, epilepsy or mental impairment due to brain cell damage.
Reasons for postpartum mental retardation
Inflammatory and infectious diseases in the infancy or childhood: flowers, rubella, diphtheria, brain inflammation, mumps, meningitis, typhus, typhoid, polio, severe (eg central nervous system) infections, muscle and reflex problems, severe jaundice after birth severe illnesses, severe accidents and shocks, various disorders in the brain of the child’s passionate or confidential transfer, can be caused by various diseases and trauma and accidents, severe economic and cultural insufficiencies, nutritional deficiencies. As a result, the mental functions of the child are at various levels of inadequacies.
It should not be forgotten that individual differences are also the case for such factors. A similar event has no negative effect on a child, but can lead to severe damage to the other child.
