Q

What are the 5 assumptions that the definition of ID must be applied in?

A 
Appropriate context
Consider cultural/linguistic diversity
Limitations coexist with strength
develop profile of needed supports
With supports life with ID will generally improve

Q

Intermittent Level of Support

A

Support is not always needed. It is provided on an “as needed” basis and is most likely to be required at life transitions (e.g., moving from school to work)

Q

When are pre-natal screenings recommended

Study These Flashcards
A 
First trimester (11-14 weeks)
2nd trimester (15-20 weeks)
21
Q

What do they look for at the first trimester screen?

Study These Flashcards
A 
nucal translucency
Blood test (PAPP-A, hCG)
22
Q

What do they look for at the 2nd trimester screen?

Study These Flashcards
A

hCG, estriol, AFP, Inhibin

23
Q

Common characteristics of Downs Syndrome

Study These Flashcards
A

Flat occiput/face, upward slating eyes, flat nasal bridge, small ears, protruding tongue
Sensory/visual deficits, hearing loss, heart defects, immune deficiency, thyroid disease, osteoporosis, sleep apnea, Alzheimers

24
Q

Musculoskeletal characteristics of Downs Syndrome

Study These Flashcards
A

Hypotonia, ligamentous laxity (atlantoaxial instability), decreased strength and cardiovascular fitness

25
Gross motor development with Down Syndrome
Occurs in same order as typically developing peers. Physical and medical characteristics of down syndrome can interfere with development (linked to mental age, gross more quickly than fine motor) Motor development improves with practice (more practice, clumsiness and decreased refinement), difficulty with balance (slower reaction times), decreased strength, strong visual learners.
26
When do gross motor skills improve the fastest?
Birth to age 6. fastest at younger ages then levels off.
27
How do DS kids compare to typical children with regard to GMS?
With DS didnt achieve all skills on GMFM by age 6, DS need more time to learn movements as complexity increases.
28
What is fragile X syndrome?
Mutation of the FMR1 geneMost commonly inherited form of ID (more males than females), females are usually the carrier
29
S/S fragile X syndrome
Facial features (some not all); large head, long face, prominent ears, chin, and forehead developmental delays social/behavioral problems seizures males usually mild-severe ID, females can have normal intelligence or some degree of ID.
30
Behavioral problems of Fragile X syndrome
``` Anxiety ADHD Sensory Defensiveness Hyperarousal Aggression Sleep disturbances Self Abuse ```
31
MSK S/S of Fragile X syndrome
``` hypotonia joint laxity joint dislocation scoliosis balance problems pes planus pectus excavatum ```
32
What are fetal alcohol spectrum disorders? (FASD)
An umbrella term for a group of conditions that can occur in a person whose mother drank alcohol during pregnancy.
33
How does FASD work?
Alcohol crosses placenta to baby, immature liver metabolizes it slowly so longer exposure to alch for baby, it's a teratogen for neurodevelopmental disorders
34
What is ARBD?
Alcohol Related Birth Defects - malformations and dysplasias of cardiac, skeletal, renal, ocular, auditory and other systems.
35
S/S Fetal Alcohol Syndrome
Abnormal facial features Growth problems CNS abnormalities Deficits in motor devel, posture, balance, coordination, gait Problems with learning, memory, attention span, communication, vision or hearing Hard time in school/trouble getting along with others.
36
Alcohol related neurodevelpomental disorder
Complex range of disabilities in neurodevelopment and behavior, adaptive skills, self regulation
37
How is ARND different from FAS
ARND includes FAS in which there are distinct facial features and growth retardation.
38
Will people with ARND have ID and problems with behavior/learning?
They might. Might to poorly inschool, have difficuties with math, memory, attention, judgement, and poor impulse control
39
What organ systems might be affected by ARBD?
heart, kidneys, bones, hearing or mix.
40
What is Prader-Willi Syndrome?
Microdeletion of long arm of paternal chromosome 15 - rare
41
S/S Prader WIlli syndrome (around birth)
Hypotonic at birth, difficulty with feeding and sucking, FTT, muscle weakness, strabismus, speech and motor delays (sit 12 mo, walking 24 mo)
42
Characteristic facial features of prader willi syndrome
almond shaped eyes, narrowing of the head at the temples, durned down mouth, thin upper lip
43
Later S/S of Prader WIlli Syndrome
Develops insatiable appetite around 2-3 y.o. Decreased growth hormone (lack of adol. growth spurt) Short stature (small hands/feet) Delayed/incomplete puberty behavior problems inadequate temperature control sleep disturbances skin picking mild ID risk for pathologic Fx 2ndary to OP d/t dec sex hormones High pain threshold
44
MSK S/S Prader WIlli
scoliosis, kyphosis, foot pronation, osteoporosis Difficulties with balance/coordination and motor planning, decreased strength Obesity related complications (type 2 diabetes, heart disease, stroke)
45
Medications for prader willi
Growth hormone, sex steroids, none effective for hyperphagia.
46
Clinical S/suggesting lesion in the hypothalmis and ANS
Altered respiration response, temp regulation, dc metabolic rate, altered BP response, increase pain tol, poor satiety rec, diminished salivation, excessive daytime sleepiness
47
What is Angelman Syndrome?
``` Microdeletion of maternal chromosome 15 UBE3A protein (important for synaptic connections in the brain) Freq misdiagnosed as CP or autism ```
48
S/S Angelman's syndrome
Developmental delay, ataxic gait/tremulous movement of limbs (quick & jerky) Hypermotoric (frequent laughing, smiling, hand flapping, waving), non-verbal or minimal use of words, short attention span. Seizures microcephaly Hypopigmentation
