What is considered intellectual disability?

Intellectual disability is a disability characterized by significant limitations both in intellectual functioning (reasoning, learning, problem solving) and in adaptive behavior, which covers a range of everyday social and practical skills. This disability originates before the age of 18.

What is profound mental retardation?

Profound Mental Retardation (MR) is defined by the presence of significantly sub average general intellectual functioning as well as significant limitations in adaptive functioning present prior to the age of 18 years. Individuals with a diagnosis of Severe MR generally obtain IQ scores below 20–25 [1, 3, 4].

What is the life expectancy of someone with mental retardation?

As the table shows, children or adults with profound, severe, or suspected retardation who were immobile, not toilet-trained, and tube-fed had a very low life expectancy and usually died within four years.

What are signs of low IQ?

Lower than average scores on IQ tests. Difficulties talking or talking late. Having problems remembering things. Inability to connect actions with consequences.

What does intellectual disability look like?

Intellectual disability1 involves problems with general mental abilities that affect functioning in two areas: intellectual functioning (such as learning, problem solving, judgement) adaptive functioning (activities of daily life such as communication and independent living)

What is the most common cause of intellectual disability?

Some of the most common known causes of intellectual disability include fetal alcohol syndrome; genetic and chromosomal conditions, such as Down syndrome and fragile X syndrome; and certain infections during pregnancy. Children who have a sibling with autism are at a higher risk of also having autism spectrum disorder.

Is mental retardation genetic?

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.

How many levels of mental retardation are there?

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 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 do they call mental retardation now?

What are the types of mental retardation?

Mental retardation comprises five general categories: borderline, mild, moderate, severe and profound. Categories are based on scores obtained through use of age-standardized tests of cognitive ability (Table 1).

What causes severe mental retardation?

Illness or injury. Infections like meningitis, whooping cough, or the measles can lead to intellectual disability. Severe head injury, near-drowning, extreme malnutrition, infections in the brain, exposure to toxic substances such as lead, and severe neglect or abuse can also cause it.

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.”

Is Autism considered an intellectual disability?

About 1% of the general population is thought to have intellectual disability, and about 10% of individuals with intellectual disability have Autism Spectrum Disorder (ASD) or autistic traits. However, a much higher percentage of individuals with ASD have intellectual disability3.
