What is mental retardation and types?
The onset of the condition occurs during the developmental period, i.e., gestation through age 18 years.
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)..
How do you test for intellectual disability?
Diagnosing Intellectual Disability Intellectual functioning is assessed with an exam by a doctor and through standardized testing. While a specific full-scale IQ test score is no longer required for diagnosis, standardized testing is used as part of diagnosing the condition.
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 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.
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.
What are the types of intellectual disability?
Types of intellectual disabilitiesFragile X syndrome. Fragile X syndrome is the most common known cause of an inherited intellectual disability worldwide. … Down syndrome. … Developmental delay. … Prader-Willi Syndrome (PWS) … Fetal alcohol spectrum disorder (FASD)
Is mental retardation curable?
A small study of 30 people with the most common inherited form of mental retardation has found encouraging evidence that some symptoms of the disorder can be alleviated with drugs.
How do I know if I’m mentally challenged?
Rolling over, sitting up, crawling, or walking much later than developmentally appropriate. Difficulty communicating or socializing with others. Lower than average scores on IQ tests. Difficulties talking or talking late.
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 age is mental retardation?
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.
What is the most common level of mental retardation?
Most affected individuals have mild mental retardation (IQ of 50 to 70). Moderate mental retardation is defined by a tested IQ of between 35 to 40 and 50 to 55. Severe mental retardation is defined by a tested IQ of between 20 to 25 and 35 to 40.
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.”
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 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.
What is intellectual behavior?
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 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).
