How many babies are born mentally challenged?

Can you tell if a baby has mental retardation in the womb?

Triple Screen Test (or Triple Marker). The Triple Screen is a blood test capable of determining whether or not your baby may be at risk for birth defects, such as Spina Bifida, or chromosomal abnormalities, such as Down Syndrome (a common form of mental retardation).

What causes mental retardation in babies?

Fragile X, a defect in the chromosome that determines sex, is the most common inherited cause of mental retardation. Single gene defects such as phenylketonuria (PKU) and other inborn errors of metabolism may also cause mental retardation if they are not found and treated early.

What causes mental retardation in unborn babies?

Causes of mental retardation include fetal alcohol syndrome and fetal alcohol effect; brain damage caused by the use of prescription or illegal drugs during pregnancy; brain injury and disease; and genetic disorders, such as Down syndrome and fragile X syndrome.

Does mental retardation come from the mother or father?

Males inheriting the full mutation from their mothers will develop symptoms while females inheriting the full mutation also have about 50% chance being affected. Affected males will not pass the mutant gene to his sons but all his daughters will be premutation carriers.

What is mild retardation?

Definition. Mild mental retardation is defined as significantly subaverage intellectual ability, which ranges between 50–55 and 70, and concurrent delays in adaptive functioning that present prior to the age of 18.
