DCD EXAM QUESTIONS AND ANSWERS
what kind of disorder is DCD
neurodevelopmental, motor disorder
pt presentation is a clumsy kid essentially
describe the development of nomenclature for DCD
"motorically awkward"
development dyspraxia
perceptual motor difficulties
Developmental Coordination Disorder (DCD): was established at the
International Consensus Conference on Children and Clumsiness 1994, 2011
diagnostic criteria was created in the DSM-V
what is the epidemiology of DCD
5-6% of all school age children
boys:girls 2:1
co-existing conditions
- ADHD
- LD
- ASD
- sensory differences
- behavioral/mental health concerns
when is DCD normally diagnosed
typically around 5 years or later
not because this is when this is happening, but rather because the requirements
,of task for this age becomes a bit more complex and differences are more
noticeable
common co-existing conditions with DCD
ADHD
LD
ASD
Sensory differences
behavioral/mental ehalth concerns
what are the risk factors for DCD
it is not well understood
risk factors: inc risk by 2x in both:
- prematurity: specifically < 32 weeks gestation
- low birth weight: < 1500gm
not causal however
- instead these factors are associated with DCD occurance
descrive the pathology of DCD
it is unknown really
but different brain activity in
- primary sensory motor cortex
- posterior superior temporal gyrus
- cerebellum
- supplemental motor area
the pathology of dCD is relatively unknown but there is different brain activity
in several areas, these brain regions are associated with which abilities
timing
motor control
motor learning
special processing
error detection
, so this is where we will see problems
T/F
there is potential that someone with DCD could struggle with any step in the
action planning system
true
describe the impairments of BSF in DCD
**not every child with DCD has the same impairments**
impaired coordination
poor spatial organization
poor feedback and feed-forward motor control
- causes them to be stuck in early stages of motor learning for longer
Poor short and LTM
Neuro "soft signs": low tone, persistent primitive reflexes, immature movement
Dec strength
Slow movement (reaction time and movement time)
"Fixing"
T/F
DCD is easy to diagnose due to the fact that all children pretty consistently
demonstrate the same impairments
false
not every child with DCD will have the same impairments
