What everyone should know about Mental Retardation


What is Mental Retardation?

  • It’s impaired or incomplete mental development. People who are mentally retarded are limited in their ability to learn and their capacity for putting learning to use.
  • Mental Retardation means SLOWING DOWN but not STOPPING
  • People who are retarded feel, think and hope, just like everyone else. Despite their limitations, they have more similarities with others than they have differences.
  • There are many different degrees of mental retardation

Causes of mental retardation:

Any condition, illness or injury that interferes with mental development before, during or after birth can cause mental retardation.

These can be either

Medical – hereditary factors, genetic abnormalities, poor prenatal care, injuries to mothers-to-be or infants, etc.
Social – lack of mental stimulation, physical abuse, poverty, discrimination and other nonmedical conditions.
There is no measurable damage to brain tissue itself in most cases of retardation. So — it’s usually impossible to know beforehand if an infant will be mentally retarded.(Retardation can occur in any family, regardless of race, income or education level.)Over 250 specific causes have been identified, but they account for only 1/4 of all cases of mental retardation.



8 Leading Known Causes of Mental Retardation

1. Infections during pregnancy. Infections are especially dangerous during the first 3 months. German measles (rubella) is one infectious disease that can cause a baby to be born retarded. It can be prevented by vaccination before pregnancy.

2. Abnormal delivery. Premature babies are more often retarded than full-term babies. Very long, extremely rapid or difficult childbirth all can cause brain damage leading to retardation. The problem usually is an insufficient oxygen supply to the baby (anoxia).



3. Infectious Illness in infancy. Infectious illnesses that most commonly affect mental development in infants are meningitis and encephalitis. These illnesses usually can be successfully treated if diagnosed early.

4. Toxic agents. These can be eaten or inhaled by a pregnant mother or a baby. Take medicines only by prescription – and with your physician’s approval. Alcohol consumption by pregnant women can cause retardation in their children, so don’t drink. Lead poisoning, contracted when small children chew lead-painted objects, can cause retardation.

5. Metabolic Disorders. Different defects in body chemistry can cause several types of retardation. Phenylketonuria, hypothyroidism, galactosemia and others can be corrected if diagnosed promptly and a proper diet is followed.

6. Rh Blood Factor Incompatability. This may lead to severe retardation. Good prenatal care and transfusions right after birth can prevent damage. New vaccines for Rh negative mothers can prevent damage to the baby in many cases.

7. Physical Malformations. Hydrocephalus (fluid accumulation in the brain) and craniosynostosis (premature hardening of the skull) sometimes result in retardation. These can sometimes be corrected by surgery.

8. Down’s Syndrome. An inborn genetic defect, Down’s Syndrome affects one out of every 600 babies. There’s no known cure, but tests are available to detect genetic disorders in parents and the unborn child. Down’s Syndrome is more common when the mother is over 35.


What is being done to help people with mental retardation?

Much basic and applied research still is needed in this field. Many basic questions still are unanswered.

Today we have the knowledge to help most people who are retarded lead fuller, happier lives through

  • Special education
  • Clinical programs
  • Social services
  • Vocational rehabilitation
  • Unfortunately, despite recent advances,
  • most people who are mentally retarded do not yet receive the professional help they need. Statistics show:about 240,000 persons in public and private residential facilities.
  • about 800,000 in regular and special education classes
  • millions still need services.



It’s time to close the gap between what is known and what is done through…

1. Early diagnosis and treatment. Retardation often is not diagnosed until children start school. This presents an unnecessary disability during the years of greatest growth.

All infants should be examined periodically for all types of disablities or abnormal conditions, including mental retardation.

2. More workers for mental retardation programs. Specially trained professionals are needed. High school and junior college graduates can build rewarding careers in this people-helping field that needs thousands of trained personnel with hundreds of different skills.

3. Expanded education and service programs. Education for individuals who are retarded can be expanded and improved.

Many needs of people who are retarded can be met through outpatient services, which can be included in community health-care plans.

4. Increased research and information exchange. This includes searching for cures, helping to find ways toprevent retardation, compiling statistics, providing genetic counseling, etc.Information, research and resource centers to share information are important tools for learning more about retardation and for putting knowledge into action.

5. New legal code and legal services for people who are retarded. There is a special need for free or low-cost legal services.

Laws based upon outdated prejudices about mental retardation should be changed. Most persons who are retarded can and should exercise the same legal rights as others.

6. More vocational opportunities and training. People who are retarded can be excellent workers and can learn a wide range of job skills.

More job opportunities are urgently needed, as well as better coordination between vocational training and job placement.

7. Family counseling and assistance. Most people with mental retardation are happier and do better as part of a family. Family counseling can help families keep members who are retarded living with them instead of in institutions, by providing emotional and pratical guidance and support.

8. New living facilities. Facilities must be available to take over when families are unable to care for a relative who is retarded.

There is a need for more group homes, foster homes, day-care centers and small residential facilities. The trend is away from larger institutions, which often lack funds and staff required for quality care.

9. More services for more people in the future. Private agencies, government and industry can work together, combining a wide range of knowledge and resources.

Cooperation is the best way to develop better distribution of services to all groups.




What you can do…..
