sever, chronic disability
*must result in 3 or more functional limitations (self-care, language, learning, mobility, self-direction)
what is replacing the term mental retardation?
intellectual disability
*signifiantly subaverage general intellectual functioning, existing concurrently with deficits in adaptive behavior and manifested during the developmental period, that adversely affects child’s educational performance
what is the incidence of intellectual disability?
3% of US pop
(6-7 million ppl)
1-10 american families directly affected by it
what is the most common cause of intellectual disabilies?
- genetic conditions leading cause
- inborn error of metabolism
- prenatal influence (drugs)

comprehensive standardized assessment of adaptive behavior that is designed for ppl from 4 to 21 years old that is a precise diagnostic info around the cutoff point where an individual is deemed to have “significant limitations” in adaptive behavior
diagnostic adaptive behavior scale
*presence of such limitations is one of the measures of intellectual disability

- -.9/1000 if mom less than 33
- -38/1000 if mom greater than 44
how do you dx downs syndrome?
- prenatal test/amniocentesis
- physical exam
- chromosomal studies
what are some characteristic physical features of dow syndrome?
- obesity
- short stature
- hypotonia
- intellectual deficiency
- palmonplanar, keratosis, xerosis
- short broad hands
- inc GI issues
- celiac disease

-is a red and white, deep, irregular ulcer, may have soft tissue enlargement, (heal in 7-14 days)
riga-fede disease
what is the tx of rida-fede disease?
ID cause, modify feeding position and device, smooth incisal surface, extract teeth, CHX rinse
