child development and special needs Flashcards
(37 cards)
what is developmental delay
present when functional aspects of the child’s development in one or more domains are significantly delayed compared to the expected level for age
what is global developmental delay
performance below 2SD below mean of age appropriate, norm referenced testing
what is a learning disability
significant impairment in intellectual functioning and affects the person’s ability to learn and problem solve in their daily life
has nearly always been present since childhood
how common is GDD
1-3% of children
? potentially up to 16%
1% have an autism spectrum disorder
when is GDD identified
only 1/3 identified before school entrance
careful evaluation and investigation can reveal a cause in 50-70% of cases
presentation of GDD - when is it picked up
routine health surveillance
children w/ identified risk factors
parental concern
professional contact - nursery/daycare
opportunistic health contact
UK healthy child programme
assessment of development in children
- hx and examination
- prenatal, perinatal and postnatal events
- developmental milestones
- red book
- environmental, SHx, FHx
- video recordings of child
- observation
1y care assessment tools for development
ASQ - ages and stages questionnaire
PEDS - parents evaluation of developmental status
M-CHAT - checklist for autism in toddlers
SOGS-2 - schedule of growing skills
quantification of developmental abilities
areas of development are age appropriate?
- delay: global (2 or more domains) vs isolated
- disorder: abnormal progression and presentation e.g. autism
- regression: loss of milestones
schedule of growing skills
information of child’s development across a range of areas
0-5yrs
9 key areas
separate cognitive score can be derived
2y care assessment tools
Griffiths mental development scales
Bayley scales of infant development
Wechsler preschool and 1y scale of intelligence

investigations - 3 important things to remember
based on clinical abnormalities
diagnostic yield of specific tests
timing
types of investigations
- genetic testing - chromosomal analysis, fragile X, FISH, array CGH
- CK
- thyroid screening
- metabolic testing: aa and organic acids, ammonia, lactate
- ophthalmological examination
- audiology assessment
- consider congenital infection e.g. toxoplasmosis, CMV
- neuroimaging
1st line investigations for GDD
following thorough hx and exam:
- chromosomes
- fragile X
- U+E
- CK
- lead
- TFT
- urate

- ferritin
- biotinidase
2nd line investigations for GDD and when are they considered
metabolic: bloods (lactate, aa, ammonia, VLCFA, carnitine, homocysteine, disialotransferrin)
- FHx
- consanguinity
- regression
- organomegaly
- coarse features
neuroimaging: MRI, CT (bones, calcification)
