What Are The Physical Adn Behavioral Characteristics Of Mental Retardation
Some do some don't: Most older kids and adults will be aware of their learning and performance difficulties when they have milder forms of intellectual impairment. The more profound the impairment, the less likely they are aware of the ramifications. ...Read more
Mental retardation is an old fashioned term now replaced with the term “Intellectual Disability”. It is defined as a measured intelligence below the normal range (less than 70) combined with inability to perform activities of daily living . For this designation a person must, in addition to having low measured ability, be significantly limited in at least two of the following areas: self-care, communication, home living, social/interpersonal skills, self-direction, use of community resources, functional academic skills, work, leisure, health, and safety. The four degrees of intellectual disability are mild, (IQ between 55-70) moderate,(between 35 and 50) , severe and profound. In the severe and profound ranges individuals have language, communication and motor impairments and cannot be tested. Profound disability, is usually associated with a neurological condition. In addition to the categories of mild, moderate, severe, and profound, categories are sometimes used to designate those intellectually disabled persons who can benefit from some degree of academic training. Those designated "educable” can handle academic work at a third-to sixth-grade level, and usually have IQs that fall between 50 and 75. The designation “trainable” refers to those who can progress as far as second grade work and can live in a sheltered string without one on one constant care. It is important to know that a measured IQ is not as important as the access to and ability to respond to emotional, ...Read more
There are several : 100's of causes of Intellectual Disability beginning with inherited mutant genes & genetic accidents that occur during egg & sperm formation; epigenetic factors like viruses that alter function but not sequence or structure of genes; teratogens like alcohol, tobacco & drugs from 3 weeks after conception till term & beyond; maternal illnesses, , etc. See pediatrics.med.nyu.edu for much more. ...Read more
Legal definition: According to the individuals with disabilities education act, intellectual disability (formerly mr) is "significant subaverage general intellectual functioning, existing concurrently with deficits in adaptive behavior and manifested during the developmental period, that adversely affects a child's educational performance." idea 2004, public law 108-446. ...Read moreSee 1 more doctor answer
Observation: Testing for mr is a matter of formal or informal observation of how a child is functioning compared to other children the same age. Approaches vary by age and circumstance. For young children, doctors may ask a series of questions about milestones that the child should be making at each check-up. There also are highly standardized formal tests that look at the child's ability directly. ...Read more
Interesting question: As defined, retardation is a permanent level of diminished intellectual performance pared with poor performance on self help tasks. Most people affected by mr are in a mild range and may integrate into society as functional adults with a relatively normal life. You cannot boost the intellect but can identify stronger areas of function within their impairments. ...Read more
Unchanged: Mr is relatively constant, partly because it is defined as a percentage of the population. One big change that has occurred over the past 10-15 years, though, is that many previously labeled as severe or profound mr now are called autistic. Mr is a less popular term--enough so that there the term is being dropped in favor of intellectual disability. ...Read more
Several levels: Broadly, mr is divided into mild, moderate, severe, and profound, contrasting actual function to chronological age. For a 10 yo, mild mr is 5-7 yo; for moderate mr, 3-5 yo; for severe mr, 2-4 yo; and for profound mr, 1-2 yo. This is not always precise--some may be stronger is some areas an weaker in others. Also, the more severe the mr, the quicker the child reaches maximum performance levels. ...Read more
Many possibilities: A brain can be genetically abnormal (chromosome defect).It can be genetically normal but injured by toxins(lead, alcohol).It can be injured by disease, meningitis, cytomegalovirus, etc. It can suffer trauma ( car crash, head injury). Each event can lead to a decline in the functional capacity of any brain with impairment varying as the degree of the disorder. ...Read more
