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 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.
How do you identify an intellectual disability?
Intellectual functioning, or IQ, is usually measured by a test called an IQ test. The average score is 100. People scoring below 70 to 75 are thought to have an intellectual disability. To measure adaptive behavior, professionals look at what a child can do in comparison to other children of his or her age.
Is mental retardation genetic?
We have not yet understood all the genetic factors involved in mental retardation. Currently more than 50 genes have been associated with syndromic and 25 genes with nonsyndromic X-linked mental retardation only and this is expected to be only 40% of the families with X-linked mental retardation.
What are the prevention of mental retardation?
1) Rubella immunization – to prevent the phenomenon of congenital rubella and its attendant morbidity. 2) Improved prenatal care – with concern for the pregnancy at risk, including improved nutrition, management of diabetes, and prevention of prematurity.
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.”
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.
What is mental retardation called now?
Intellectual disability (ID), once called mental retardation, is characterized by below-average intelligence or mental ability and a lack of skills necessary for day-to-day living.
What are the stages 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 is severe mental retardation?
Definition. Severe Mental Retardation is defined by the presence of significantly subaverage general intellectual functioning as well as significant limitations in adaptive functioning (adaptive behavior) present prior to the age of 18 years.
What are the 4 levels of mental retardation?
The condition is further divided into four levels of retardation based on IQ, which include mild mental retardation (IQ between 50-55 and 70), moderate mental retardation (IQ between 35-40 and 50-55), severe mental retardation (IQ between 20-25 and 35-40), and profound mental retardation (IQ below 20 or 25) (American …
What is the life expectancy of a person with mental retardation?
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.
