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 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.
Is Autism & intellectual disability the same thing?
Autism, on the other hand, is defined primarily by social difficulties, communication issues and repetitive behaviors. Yet intellectual disability comes with a suite of developmental delays that can include social differences, and that can lead clinicians astray.
Is mental retardation reversible?
“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 an intellectual disability be cured?
Intellectual disability is not a disease and cannot be cured, however early diagnosis and ongoing interventions can improve adaptive functioning throughout one’s childhood and into adulthood. With ongoing support and interventions, children with intellectual disability can learn to do many things.
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.
Is the most common hereditary cause of mental retardation?
X-linked mental retardation Fragile X syndrome is the most common inherited form of mental retardation and, after Down syndrome, the most common genetic form. It is X linked, with dominant inheritance, and the penetrance is lower in females.
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 does mental retardation affect a child?
Mental retardation is identified between birth and six years old. Affected children tend to lag behind peers in coordination, social skills, and language development. Many children with mental retardation require support from doctors, neurologists, therapists and social workers to increase functioning.
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 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.
