Intellectual Disability and Fetal Alcohol Syndrome Flashcards
Eugenics movement
1900-1930 heyday - segregation, sterilization, restrictive immigration policies
DSM-5 intellectual disability
- Diagnosed prior to 18 yrs old
- These two criteria are NEEDED
- IQ is less than or equal to 65-75
- Impairment in adaptive functioning
in 2 or more areas
- Communication, self-care,
home living, social skills, use
of community resources, self-
direction, academics, leisure,
health, safety
Intellectual disability prevalence
1-3% overall
Mild is 85% of that
Common sources of information in assessing intellectual disability
- IQ testing
- Interview parents/caregivers
↪ Adaptive functioning scales
↪ Scales of Independent Behavior - Direct observation
Etiological factors in intellectual disability
Complicated & varied
Two group approach: distinction between organic and cultural/familial
Organic: early environmental issues can impact IQs
Cultural/familial: genetics
Chromosomal abnormalities and intellectual disability: List
- Down syndrome
- Fragile X syndrome
- Prader-Willi syndrome
- Angelman syndrome
What is Down Syndrome?
Extra 21st chromosome (“trisomy 21”).
~ 1 in 1000 population but rises with maternal age
What is Fragile X Syndrome?
Significant intellectual disability
Protruding ears
Male-dominated
Difference in X chromosome
1/10,000
Prader-Willi Syndrome
Inherited from MOTHER
Constant hunger ➛ high obesity risk
Chromosome 15
Angelmann Syndrome
Inherited from FATHER
Chromosome 15
Pointed ears, elfin face, intense need for socialization ➛ loneliness, anxiety
What is Fetal Alcohol Syndrome characterized by?
Characterized by:
1. Facial characteristics
↪ epicanthal folds, thin palpebral fissure, wide nose bridge, flat philtrum
- Lower head circumference and physical growth retardation
- Intellectual disability and/or neuropsychological impairment
Fetal Alcohol Spectrum Disorder
Some, but not all, of the requirements for FAS
FAS prevalence
< 1%
FASD prevalence
~1%
FAS - limitation of alcohol
Greatest concern over binge drinking – 5+ drinks in one sitting, especially in early pregnancy.
There was an animal study showing 2 drinks leading to impairment, but the clinical implications are unclear.
