Genetic: Prenatal screening for genetic defects and genetic counseling for families at risk for known heritable disorders can decrease the incidence of genetically caused mental retardation.
Social: Government programs to insure adequate nutrition are available to the underprivileged in the first and most critical years of life, which can reduce retardation associated with malnutrition. Social programs to reduce poverty and provide good education can impact the mild "retardation" associated with impoverished and lower socioeconomic status. Early intervention in abuse and deprivation will also help.
Toxic: Environmental programs to reduce lead and mercury exposure and other toxins will reduce toxin-associated retardation. However, the benefits may take years to become apparent. Increased awareness by the public of the effects of alcohol and drugs during pregnancy can reduce the incidence of retardation.
Infectious: The prevention of congenital rubella syndrome is probably one of the best examples of a successful program to prevent one form of mental retardation. Constant vigilance, such as in the relationship of cats, toxoplasmosis, and pregnancy, helps to reduce retardation that results from this infection.
