Do Professionals agree or disagree about the definition, classification, and terminology of intellectual disabilities.
disagree
Does a person’s level of intellectual functioning remains stable throughout his/her life.
no
Is it difficult to pinpoint the cause of intellectual disabilities in many people?
yes
When do many authorities believe that it is appropriate to introduce vocational content to students with intellectual disabilities?
elementary school
What is he most significant change in the field of intellectual disabilities?
the fact that the name changed from mental retardation to intellectual and developmental disabilities.
mandated that “intellectual disability” replace “mental retardation” in many areas of the federal government
Rosa’s Law
Which groups of children are disproportionately identified as intellectually disabled by the public schools?
African American and Native American
A disability characterized by significant limitations both in intellectual functioning and in adaptive behavior as expressed in conceptual, social, and practical adaptive skills. This ability originates before age 18
intellectual disability
the social and practical intelligence used in people’s everyday lives; along with IQ, is considered in making a determination of intellectual disability
adaptive behavior
According to the AAIDD, can intellectual functioning and adaptive behavior can be improved
yes
What involves being able to “read” when someone is angry and not being gullible or easily tricked or manipulated?
social intelligence
What involves the ability to solve everyday problems, such as preparing meals, using transportation, making change, using the Internet, etc…
practical intelligence
resources and strategies that promote a person’s development, education, interests, and personal well-being; critical to the AAIDD’s conceptualization of intellectual disabilities

What is the cognitive ability of a student with mild intellectual disabilities?
IQ of 50 to 70
What is the cognitive ability of a student with moderate intellectual disabilities?
IQ of 35 to 50
What is the cognitive ability of a student with severe intellectual disabilities?
IQ of 20 to 35
What is the cognitive ability of a student with profound intellectual disabilities?
IQ below about 20
What is the average (mean) score on an IQ test?
100
According to the hypothetical “normal curve,” approximately what percentage of the population is expected to have IQ scores between 0-70?
2.27%
In recent years, the percentage of cases in which the cause of intellectual disabilities is known has dramatically increased due to
the mapping of the human genetic code.
A common way to categorize causes of intellectual disabilities is to consider the
time at which the cause occurs.
any of several syndromes resulting from abnormal or damaged chromosomes; can result in intellectual disabilities
chromosomal disorders
A condition resulting from an abnormality with the 21st pair of chromosomes
down syndrome
a type of down syndrome in which the twenty-first chromosome is a triplet
trisomy 21
Claudia is a third grader with intellectual disabilities. She has thick epicanthal folds in the corner of her eyes, small stature, decreased muscle tone, speckling of the iris of the eye, a small oral cavity, and short, broad hands with a single palmar crease. These characteristics are typical of
Down syndrome.
Alzheimer’s disease has been linked to which cause of intellectual disabilities?
down syndrome
What is the name of the child in the video on down syndrome?
Bradley
Does the likelihood of having a child with Down syndrome increases with the age of the mother?
yes
A method of screening the fetus for developmental disabilities such as Down syndrome or spina bifida; a blood sample is take from the mother and analyzed
maternal serum screening (MSS)
A congenital midline defect resulting from failure of the bony spinal column to close completely during fetal development
spina bifida
A medical procedure that allows examination of the amniotic fluid around the fetus
amniocentesis
A method of testing the unborn fetus for a variety of chromosomal abnormalities, such as down syndrome; a small amount of tissue from the chorion is extracted and tested
chorionic villus sampling (CVS)
A method of screening for Down syndrome; fluid from behind the fetus’s neck and protein from the mother’s blood are analyzed
Nuchal translucency ultrasound
Fragile X syndrome occurs more often in
males
A condition in which the bottom of the X chromosome in the twenty-third pair of chromosomes is pinched off; can result in a number of physical anomalies as well as intellectual disabilities
Fragile X syndrome
Caused by inheriting from one’s father a lack of genetic material on the fifteenth pair of chromosomes; leading genetic cause of obesity; degree of intellectual disabilities varies, but the majority fall within the mildly intellectually disabled range
Prader-Willi syndrome
cessation of breathing while sleeping
sleep apnea
an abnormal curvature of the spine
scoliosis
A condition resulting from deletion of material in the seventh pair of chromosomes; often results in mild to moderate intellectual disabilities, heart defects, and elfin facial features; people affected often display surprising strengths in spoken language and sociability while having severe deficits in spatial organization, reading, writing, and math
Williams Syndrome
Deficiencies in enzymes used to metabolize basic substances in the body, such as amino acids, carbohydrates, vitamins, or trace elements; can sometimes result in intellectual disabilities
Inborn errors of metabolism
A metabolic genetic disorder caused by the inability of the body to convert penylalanine to tyrosine; an accumulation of phenylalanine results in abnormal brain development
Phenylketonuria (PKU)
A condition causing development of a small conical-shaped head; proper development of the brain is prevented, resulting in intellectual disabilities
microcephalus
A surgically placed shunt that drains excess fluid away from the brain is used to treat
hydrocephalus
A condition characterized by enlargement of the head because of excessive pressure of the cerebrospinal fluid
hydrocephalus
Fetal alcohol syndrome is classified as resulting from a/an
environmental hazard
A range of disorders in children whose mothers consume large quantities of alcohol during pregnancy
fetal alcohol spectrum disorders (FASD)
Abnormalties associated with the mother’s drinking alcohol during pregnancy; defects range from mild to severs, including growth retardation, brain damage, intellectual disability, hyperactivity, anomalies of the face, and heart failure
fetal alcohol spectrum (FAS)
A serious viral disease, which, if it occurs during the first trimester of pregnancy, is likely to cause a deformity in the fetus
Rubella (German measles)
Deprivation of oxygen
anoxia
Babies who are born weighing less than 5.5 pounds; usually premature
Low birth weight (LBW)
What are three perinatal causes to intellectual disabilities
anoxia, low birth weight, infections such as syphilis and herpes simplex
A venereal disease that can cause mental subnormality in a child, especially if it is contracted by the mother-to-be during the latter stages of fetal development
syphilis
