Mental Retardation (Definition)

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

Specific testing: All children develop at different rates. Some learn to talk early (especially girls), some late, and some regress in language. Some develop rapid motor skills while others are much slower. Special testing can be done at school age to measure learning ability and to establish a scale of aptitude.

Many children with genetic risks are developmentally normal. ...Read more

What are the symptoms associated with developmental delay?

Each developmental: domain has a range of ages at which typically-developing infants & toddlers reach expected milestones. Screening for these is on firstsigns.org. Not attaining a milestone by the age at which 90% of children do so is a delay. The trajectory of development over time is more important than reaching a milestone at a single point in time. Developmental surveillance is, therefore,recommended by the AAP. ...Read more

For instance, most babies are pulling up on furniture and attempting to take a first step around their first birthday. If they get to 15-16 months and aren't doing it, we say that's a delayed ...Read more
