What causes learning disorders?

Learning disorders are caused by the malfunctioning of the brain. Some disorders involve multiple sites of the brain, and these sites can be different in men and women. The damage in the brain may be genetic, or it can be due to problems encountered at birth.

Causes of learning disorders may develop during pregnancy. The fetal brain grows from a small number of all purpose cells, and develops into an organ consisting of millions of neurons, which are interconnected nerve cells. While this marvelous evolution is taking place, something can go wrong which may affect how the neurons are made and interconnect.

Other causes of learning disorders may be exposure to alcohol during pregnancy that may cause damage.

Because of the damage causing the learning disorders, the nerve cells are wrongly placed, or they are not organized properly or some may even be missing.

Learning disorders can also be inherited; if one of the parents has a learning disorder, some of the children are likely to inherit it also.

While looking at causes of learning disorders, can the disability be due to a brain tumor or something similar?

Learning disorders are present from the time of a person’s birth. Learning disorders cannot suddenly show up in a child who did not have any previous symptoms. If something like this does happen, then multiple tests have to be conducted to determine whether a stroke, or tumor, or some disease or unusual growth of blood vessels is causing the disorder.

But in cases where learning disorders have been present from birth and are constantly present, one can be sure that they are not caused by neurological diseases.

Prevalence of learning disorders

It is difficult to say how many children suffer from learning disorders, because it is hard to arrive at an agreement on how far behind a person has to be, to belong to the disorder category. If one uses the level of two grades behind where a child should be, then 5- 10% of the people suffer from learning disorders. It was thought in the past that more males than females had the disorder, but now this has been disproved.
