Generally speaking, mental disabilities such as the antiquated term retardation are diagnosed anytime before the age of 18. Specifically though, it is possible to reach a diagnosis as early as 24 months.
IQ is not strongly associated with age. An IQ of 56 represents mental retardation, but nothing about the person's age.
Developmental disability can be retardation. A developmental disability is a mental/physical impairment onset before the age of 22. A developmental disability affects three or more of daily living activities like independent living, learning, mobility and self-care. Examples of dd are not only mental retardation, but cerebral palsy, autism and Down Syndrome.
Retardation is holding something back. In a way, applying the brakes in a car is retardation.
The word "moron", which is now considered to be outdated and cruel, was a term used in the psychological community to describe someone who had an IQ of 51-70 (or a mental age of 8-12). This is now called "mild mental retardation".
Medical Encyclopedia: Mental Retardation Definition Mental retardation is a developmental disability that first appears in children under the age of 18. It is defined as an intellectual functioning level (as measured by standard tests for intelligence quotient) that is well below average and significant limitations in daily living skills (adaptive functioning). Description Mental retardation occurs in 2.5-3% of the general population. About 6-7.5 million mentally retarded individuals live in the United States alone. Mental retardation begins in childhood or adolescence before the age of 18. In most cases, it persists throughout adulthood. A diagnosis of mental retardation is made if an individual has an intellectual functioning level well below average and significant limitations in two or more adaptive skill areas. Intellectual functioning level is defined by standardized tests that measure the ability to reason in terms of mental age (intelligence quotient or IQ). Mental retardation is defined as IQ score below 70-75. Dictionary: mental retardation n. Subnormal intellectual development as a result of congenital causes, brain injury, or disease and characterized by any of various cognitive deficiencies, including impaired learning, social, and vocational ability. Also called mental deficiency. Neurological Disorder: Mental retardation Definition Mental retardation (MR) is a developmental disability that first appears in children under the age of 18. It is defined as a level of intellectual functioning (as measured by standard intelligence tests) that is well below average and results in significant limitations in the person's daily living skills (adaptive functioning). Sci-Tech Encyclopedia: Mental retardation A developmental disability characterized by significantly subaverage general intellectual functioning, with concurrent deficits in adaptive behavior. The causes are many and include both genetic and environmental factors as well as interactions between the two. In most cases the diagnosis is not formally made until children have entered into school settings. In the preschool years, the diagnosis is more likely to be established by evidence of delayed maturation in the areas of sensory-motor, adaptive, cognitive, social, and verbal behaviors. By definition, evidence of mental retardation must exist prior to adulthood, where vocational limitation may be evident, but the need for supervision or support may persist beyond the usual age of social emancipation. http://www.answers.com/mentally%20retarded
There are three criteria for mental retardation. 1) IQ must be below approximately 70, as measured by an intelligence test, or in roughly the bottom 2% of the population. 2) This decline in IQ must interfere with the person's ability to function in daily life. For example, a person with mild mental retardation may have difficulty handling money, cooking for themselves, or taking medicine as prescribed. 3) Onset of these difficulties must occur prior to age 18. This is why, when a person develops these problems as a result of Alzheimer's Disease or other dementia, they are not described as mentally retarded.
