peds: learning disorder&disability Flashcards
what three things should an evaluation of a developmental delay include?
Evaluation should define developmental deficits, determine reason if possible, and plan for a treatment program
5 types of developmental delays
- Intellectual Disability
- Specific Learning Disorder
- Communication Disorders
- Motor Disorders
- Autism Spectrum Disorder
what are the 3 areas that a “specific learning disorder: could be in?
Written expression
Reading
Math
4 types of communication disorders
Language Disorder
Speech Sound Disorder
Childhood Onset Fluency Disorder (Stuttering)
Social (Pragmatic) Communication Disorder
3 types of motor disorders
Developmental Coordination Disorder
Stereotypic Movement Disorder
Tic Disorders
intellectual developmental disorder (intell. disbality): an Impairment in development of _______ and ______ functioning, dx by what three things?
cognitive and adaptive fxning
a. Deficits in intellectual functioning (low scores on formal IQ tests, <70)
b. Impaired functioning in adaptive functioning
(1+ activities of daily life, across multiple environments)
c. Onset during the developmental period
normal IQ is ____ with a standard deviation of about ___
100, 10-15
Intellectual disability is diagnosed based on…
a. IQ Score
b. Deficits in adaptive functioning
c. Both IQ score and deficits in adaptive functioning
C. BOTH
etiology of ID, if its more severe are you more or less likely to find that cause?
more likely!
etiology of ID: prenatal
genetic syndromes, brain malformations, maternal disease, environmental (alcohol, drugs, toxins)
etiology of ID: perinatal
labor and delivery-related events leading to neonatal encephalopathy
etiology of ID: postnatal
hypoxic ischemic injury, traumatic brain injury, infections, demyelinating disorders, seizure disorders, severe and chronic social deprivation, toxic metabolic syndromes (lead, mercury)
Down syndrome: what is the cause? IQ range? what increases the risk of this occuring?
extra chromosome on 21st pair.
Broad IQ range – mean 47-50
high maternal age increases risk
down syndrome, what are they more susceptible to? life expectancy?
Susceptible to infections, particularly respiratory
Few reach 50 years old; many die in childhood
what is Fragile X ?
Small section of genetic code repeated on X chromosome
Severe to mild ID (intellectual disability)
fragile X: what type of delays? physical features? (kinda weeds)
Delay in crawling, walking, or twisting; hand clapping or hand biting; hyperactive or impulsive behavior; speech and language delay; tendency to avoid eye contact
Physical : flat feet, flexible joints and low muscle tone, large body size, large forehead or ears with prominent jaw, long face, soft skin
trisomy 18: what is the cause? what is one major key feature?
Third copy of genetic material from chromosome 18, instead of the usual two copies
- rocker-bottom feet
what is prader-willi syndrome
disease that involves obesity, (strong craving for food) decreased muscle tone, decreased mental capacity, and sex glands that produce little or no hormones.
two types of single gene defects (no family history)
prader- willi and wilson’s disease
what is wilson’s disease?
disorder in which there is too much copper in the body’s
tissues. The excess copper damages the liver and nervous system
most common preventable cause of ID?
fetal alcohol syndrome
3 signs of fetal alcohol syndrome
- CNS deficits (low IQ), ADHD symptoms
- Faces with broad set eyes, narrow eye
slits, flat cheeks, short nose, thin upper
lip & nose, flat philtrum - Growth retardation
4 signs in pregnancy of a possible ID
- loss of fetal growth, minimal fetal movement
- abnormal weight gain by mother
- maternal drug or alcohol use
- illness during pregnancy (rubella, syphilis, HIV especially)
signs during birth of possible ID
not looking normal at birth, small
