What are the causes of the birth of children with disabilities?
According to statistics, about 3% of all children born in the world are born with abnormalities. However, in fact, developmental disabilities are more common. Nature is designed in such a way that, in most cases, children with developmental disorders do not appear at all; die early in the development stage. So, about 70% of all spontaneous abortions at a term of up to 6 weeks occur due to gene anomalies.
In order to understand what children are born with deviations and in what cases it happens, it is necessary to know about the possible causes of the development of violations. All of them can be conditionally divided into: external (exogenous) and internal (endogenous).
External factors include those factors that have influenced the body from the outside, have led to the development of deviations. It can be:
- negative impact of the environment;
- abdominal trauma in pregnant women;
- presence of chronic infections (eg, toxoplasmosis );
- use of medicines.
Among the endogenous factors in the first place are genetic anomalies. Their appearance is directly influenced by:
- age of parents;
- heredity - if the parents had deviations in development, then the share of the probability of occurrence of such in children is great;
- negative impact of environmental factors (living in industrial areas, work at the enterprise of the radiological industry, etc.).
Also, if the father is already 40 years old, a child with deviations may be born, and it does not depend on whether he has a health disorder or not. The fact is that according to studies of Western scientists, it is in men with age that the risk of anomalies of germ cells increases, which in the end can lead to deviations in children.
