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.
FAS associations
Poverty and smoking
Washington Diagnostic System for FASD
Four aspects
1. Growth deficiency
2. Brain dysfunction
3. FAS facial features
4. Alcohol exposure
Ranked 1-4,
↪1: none
2: unknown
3: some risk
4: high risk
Pediatrician and psychologist score, then use scores to assign to patterns
Washington Diagnostic System Patterns
Growth 3, Face 4, Brain 3, Alcohol 4 = FAS
Growth 2, Face 4, Brain 4, Alcohol 3 = Atypical FAS (some difference in presentation)
Growth 2, Face 3, Brain 3, Alcohol 2 = Static Encephalopathy (stable damage to brain, can’t be certain that alcohol was the cause)
Lack of FAS facial features
Alcohol Related Neurodevelopmental Disability (ARND)
FAS interventions
Individually tailored
Depends on nature of impairment. Can include life skills training, executive function tasks, traditional behavior therapy for problem behaviors.
Medicine is also an option for attention and/or mood problems.
