Is mental retardation a genetic disorder?
Mental retardation is caused by a number of different factors.
Among genetic disorders, Fragile X syndrome and Down syndrome are the commonest causes of mental retardation.
Fragile X syndrome (FXS) is an inherited form of mental retardation.
FXS is estimated to affect 1 in 2,500 males and 1 in 8,000 females..
At what age is mental retardation diagnosed?
When is the diagnosis made? The onset of mental retardation is in childhood, before 18 years of age. The diagnosis is generally made after infancy, between the preschool and school-age periods. Sometimes the diagnosis may be made later, at the time when a thorough assessment is performed.
Is mental retardation a birth defect?
What is Down syndrome? Down syndrome is a genetic disorder that includes a combination of birth defects, including some degree of mental retardation, characteristic facial features and, often, heart defects, visual and hearing impairment, and other health problems.
What is the life expectancy of a person with mental retardation?
Results. Kaplan-Meier survival plots showed a strong negative association between severity of intellectual disability and survival, with median life expectancies of 74.0, 67.6, and 58.6 years for people with mild, moderate, and severe lev- els of handicap.
What is borderline mental retardation?
Borderline intellectual functioning, also called borderline mental retardation (in the ICD-8), is a categorization of intelligence wherein a person has below average cognitive ability (generally an IQ of 70–85), but the deficit is not as severe as intellectual disability (below 70).
What are the signs of mild retardation in adults?
Such challenges may include the following:Memory problems.Attention problems.Difficulties interacting socially.Impaired self-esteem or lowered sense of self-worth.Difficulties finding and maintain employment as adults.Being unable to live on one’s own due to required assistance and supervision.More items…
What are the 4 levels of mental retardation?
The DSM-IV classifies mental retardation into four stages based on severity: mild (IQ score of 50-55 to approximately 70), moderate (IQ score of 30-35 to 50-55), severe (IQ score of 20-25 to 35-40), and profound (IQ score of less than 20-25).
What are signs of low IQ?
Lower than average scores on IQ tests. Difficulties talking or talking late. Having problems remembering things….IQ 50-70.Slower than normal in all areas.Can conform socially.Can acquire daily task skills.Integrated in society.No unusual physical signs.Can acquire practical skills.Reading and math skills up to grades 3-6.
Can MRI detect mental retardation?
MRI allows detection of multiple minor morphological anomalies. Most have classically been considered as normal variants but they may in fact be markers of cerebral dysgenesis and are currently the only anomaly detected in the work-up of patients with mental retardation.
What causes mild mental retardation?
trauma before birth, such as an infection or exposure to alcohol, drugs, or other toxins. trauma during birth, such as oxygen deprivation or premature delivery. inherited disorders, such as phenylketonuria (PKU) or Tay-Sachs disease. chromosome abnormalities, such as Down syndrome.

What is the most common cause of mental retardation?
Down’s syndrome is the most common specific cause of mental retardation, followed by the Fragile X syndrome, which mainly affects boys.
Does mental retardation get worse with age?
What mental changes occur, as adults with mental- retardation grow older? Like the general population after age 50, people with mental retardation, who do not have Down syndrome, experience a gradual decline in overall intellectual capacity, a decrease in their speed of recall, and slower general cognitive functioning.
What is considered a mild disability?
Mild disability is marked by the ability to learn practical life skills, blend in socially, attain reading and math skills up to grade level 3-6, be functional in daily life, and have no observable physical signs of disability.
Can mental retardation be reversed?
“The same mutation in animals produces learning disorders, which we were able to eliminate in adult mice. Our work and other recent studies suggest that some forms of mental retardation can be reversed, even in the adult brain.”
