What Causes Mental Retardation?
While there are many causes of mental retardation, doctors find the condition in only 25% of the cases. There are risk factors associated with the causes of mental retardation. The roots of intellectual disability can be divided into several categories 1:
Infections which may manifest themselves at birth or right after birth. This may include HIV infection, meningitis, listeriosis, congenital CMV or rubella, encephalitis, among others.
Chromosomal abnormalities which may include cri du chat syndrome, translocation of a gene, fragile X syndrome, or discrepancies in the number of chromosomes, such as the Down’s syndrome.
Environmental causes such as the deprivation syndrome
Genetic abnormalities and inherited metabolic conditions such as phenylketonuria, galactosemia, Hurler syndrome, to name a few.
Metabolic causes such as hypoglycemia, congenital hypothyroid, and hyperbilirubinemia
Pre and post-natal trauma such as sever head injuries, intracranial hemorrhage
