What are the different types of mental retardation syndromes?

There are several different types of mental retardation syndromes that can affect people from which Down syndrome and autism are one of the most commonly known. MyCrocephaly and Cretinism are some forms of mental retardation caused by insufficient brain development.

Down syndrome is one of the first things that come to mind when one thinks about the types of mental retardation syndromes. This disorder is genetic and occurs when an individual has more than 46 chromosomes, causing developmental problems in the brain. Down syndrome is easily identified by abnormal facial features such as flat nose, thick eyelids and large ears, among other things. It seems that autism affects people in a very different way. Research has brought some understanding of this disorder, but it will still learn about the brain function of people with autism. It is understood that people with autism are thin other than those with normal brains, which reduces social interactive abilities, but sometimes also increases capabilities in areas like matheme. Verbal skills are usually insufficiently developed and eye contact is rare in people with this disorder.

One of the mental retardation syndromes, which is caused by impaired brain development, is called MyCrocephaly. The name literally means a small head, because the brain, and then the head, is insufficiently developed during pregnancy. The appearance of each child with mecrocephali will vary a bit, but the affected individuals tend to have a head of about 17 inches (43.18 cm) compared to a normal head size of about 22 inches (55.88 cm) and often have a cone -shaped skull. These children have a very limited mental capacity and tend to develop very small language skills.

Cretinism is a type of mental retardation syndrome, which is caused by a thyroid deficiency. This disorder is sometimes caused during fetal development where the thyroid gland is insufficiently developed but can also be caused in DOSthe panel before injury to the thyroid gland. Some diseases such as measles, diphocks and black cough may cause this disorder when bleeding enters the thyroid gland. Early treatment has shown some success in supporting mental development, but if no treatment is adopted in the first year of life, the effects are often permanent.
