Developmental Coordination Disorder Flashcards
what was DCD previously called?
clumsy child, development clumsiness, developmental apraxia, motor coordination problem, dyspraxia, perceptual motor dysfunction
Prevalence of development coordination disorder
3-5%
- 5-6% of school age children
- M:F ratio is 2:1
Who has a higher risk of development coordination disorder?
children born weighting less than 3.3lbs or before 32 weeks gestation
pathophysiology of DCD
- dysfunction of cortical networks
- changes in white matter
- less activation in areas associated with timing, motor control, spatial. and error processing
DCD and coexisting conditions
- LD: learning disabilities
- ADHD: attention deficit hyperactivity disorder
- Sensory integration/ Sensory motor disorder
- Autism spectrum disorder
Percent of children with DCD who have epilepsy
25%
How is DCD diagnosed?
through classification in the Diagnostic and Statistical Manual of Mental Disorders - 5th Edition
- Neurodevelopmental Disorder
- Subcategory: motor disorder
- 4 criteria
DSM-V Diagnostic Category
- Acquisition and execution of coordinated motor skill are substantially below what is expected for age
- Motor skill deficit interferes with academic achievement, ADL, leisure and play
- Onset of symptoms is in early development
- Deficits are not better explained by intellectual disability, visual impairment, or a neuron condition such as CP, MD, or a degenerative disorder
Common characteristics of DCD
- delayed motor development
- clumsiness
- balance and coordination problems
- handwriting problems
- hypotonia/joint laxity
- overweight or obese
- low fitness level
multi-system involvement
motor –> information processing –> psychosocial –> repeat
DCD involves…
social, concentration, organization, fine motor, communication, gross motor
Difficulties with motor skills
- Difficulty with ADLs (utensils for eating, dressing)
- Difficulty with handwriting or drawing
- Difficulties with balance and coordination
- Poor praxis
- Low muscle tone
- lower level of fitness than age-matched peers
Information processing/sensory issues
- impaired ability to judge distance
- poor body awareness
- poor timing
- short and long term memory issues related to sequencing motor tasks
- perceptual deficits
- slower response times
psychosocial difficulties
- learning difficulties
- reading problems
- behavior problems
- poor interactive play skills
- lower self esteem
- lower self worth
- increased anxiety
Standards for Screening and Examination of DCD
- European Academy of Childhood Disability Guidelines
- Academy of Pediatric PT CPG
