Quiz 3 Flashcards
3 Major Criteria for Intellectual Disability
- Manifest before 18 years old
- IQ score falls 2 SD below mean < 65-75
- Adaptive behavior skills deficit in : communication, self-care, social skills, home living, self direction, leisure, work, health & safety, academics
Difficulties with reasoning, problem solving, planning, abstract thinking, judgment, learning from instruction and experience
Intellectual Disability IQ Score
100 Normal or average IQ
Blew 70-75 = DSM V classification for ID
70-79: Borderline
55-69: Mild (most common)
40-54: Moderate
25-39: Severe
Below 25: Profound
Intellectual Disability Incidence
Males more than females; 1-3% of population
6 out of 1,000 with severe disability
Down Syndrome most prevalent form
1 in 800-1,000 live births
Causes: infections, chromosomal abnormalities, environmental causes, no specific etiology
Motor Impairments with ID
Hypotonia, motor control, postural control, balance, force production, flexibility
Assessment & Intervention
Identify the smallest of the child’s abilities
Focus intervention to maximize those abilities
Must inform parents/team of positive abilities
Determine basic responsiveness
Visual stimulation and vestibular input activities to practice tracking and focusing
Heavy touch and pressure or weight bearing
Choose activities that stimulate antigravity extensor (swings, barrels, scooter boards)
Treatment Principles for Children with ID
Use all areas for potential learning (motor, cognitive, affective)
Choose activities that accommodate the “mental” age of the child
Activities should be meaningful and functional
Use repetition and consistency
Establish appropriate goals
Down Syndrome
Chromosomal disorder that results in 47 chromosomes instead of 46
Affects the 21st pair of chromosomes (Trisomy 21)
Most common cause of Intellectual Disability
Types of Down Syndrome
- Trisomy 21 (no disjunction) caused by a faulty cell division that results in having 3 #21 chromosomes
Most common (90-95% have this type) - Translocation (3-4% of all cases) #21 breaks of during cell division and attaches to another chromosome
Genetic predisposition, parent may be carrier - Mosaicism: occurs when some cells receive an extra copy of chromosome 21, Others do not after fertilization
Least common type
Diagnosis of Down Syndrome
Usually identified at birth or shortly after
Based on physical characteristics: low muscle tone, single palm crease, flattened facial profile, upward slant in eyes
Amniocentesis performed 12-20 weeks gestation
Chronic Villus Sampling between 8-12 weeks
Percutaneous Umbilical Blood Sampling performed after 20 weeks
Down Syndrome Health Issues
Brain weight - 76% of normal (microbrachycephaly, decreased # of secondary sulci, decreased # of neurons & synapses, delayed or lack of myelination, seizure disorder, increase in Alzheimer tangles)
Congenital heart defects (VSD)
Visual/Hearing: adult onset cataracts, strabismus, nystagmus, otitis media, hearing loss
Higher incidence of infection, respiratory, vision, hearing problems
Life expectancy 55 years, may be older
Decreased stature, leg length, finger length, hypotonia, ligamentous laxity, decreased strength, Pes Plannus, Patellar Instability, Atlanta-axial instability, Scoliosis, Hip dysplasia
Premature aging seen
Wide space between 1st and 2nd toe, small nose, narrow palate, small mouth, delayed formation of teeth, protruding abdomen
Assessment of Hypotonia
Morgan-Paleg Hypotonia Scale
Score 1-3 (1=normal, 2=mod, 3=severe)
1. Head control
2. Vertical suspension
3. Sitting
4. Hip abduction
5. Ankle dorsiflexion
6. Standing
Assessment of Ligamentous Laxity
Score of > or = 4/9 considered indicative of generalized hypermobility
Apposition of thumb to forearm
Extension of pinky to 90 degrees
Extension of elbow beyond 90 degrees
Extension of knee beyond 10 degrees
Forward flexion of trunk, legs straight, palms touching floor
Orthotics
Have child fitted for orthotics when they begin to pull to stand and cruise
Wear 50% of the time
During therapy use orthotics with postural work or play
SMO
Hip helper shorts
Minimize external rotation and excessive abduction in babies and toddlers with low muscle tone
Improves rotational movement and limits W sitting
Designed for babies 6 months to 3 yrs old
Standers
Start at 9 months if child is not sitting independently for play
Start at 12-15 months if child is not yet pulling to stand or cruising
Position in hip abduction
Treadmills
Recommend 8 min 5x a week for pre-walkers
Or 20min 5x a week for older children
Gait Trainers
If no treadmill, start at 9-12 months
Aging with Down Syndrome
Hypothyroidism: low energy, weight gain, bradycardia, constipation, dry skin
Cardiovascular: mitral valve prolapse
Obesity: 79% male, 69% female
Arthritis, hip dysplasia, osteoporosis
Alzheimer’s Disease
Depression
ADHD criteria
symptoms present for 6 months that is maladaptive and inconsistent with development level of the child
clinically significant impairment present in 2 or more settings
onset of impairment must be before age 7, even if diagnosed later
boys>girls
most common type is combined inattentive and hyperactive-impulsive
when girls diagnosed, most often it is inattentive type
Inattention symptoms
- careless mistakes
- Attention difficulty
- Listening problem
- Loses things
- Fails to finish things
- Organizational skills lacking
- Reluctance in tasks requiring sustained mental effort

- Unable to wait his/her turn
- Not able to play quietly
- On the go
- Fidgets with hands or feet

ADHD exclusion criteria
ADHD is not diagnosed if the symptoms occur in the course of a pervasive developmental disorder, psychotic disorder OR
if the symptoms are likely due to another psychiatric disorder
ADHD Co-Morbid Conditions
Oppositional Defiant Disorder: pervasive pattern of negativistic, defiant, disobedient, and
hostile behaviors toward authority figures
Conduct Disorder: Repetitive pattern of violating the basic rights of others and/or societal laws
Mood Disorders: depression, bipolar
Anxiety
Learning Disorders
**Child with ADHD + Conduct Disorder more likely to develop antisocial behavior
Medications and Side Effects for ADHD
Methylphenidates & Amphetamines (appetite loss, sleep distrubance, changes in blood pressure/pulse, dysphoria, irritability, exacerbation of tics)
Strattera (nausea, headache, anorexia, insomnia)
