Developmental Coordination Disorder (DCD), or Dyspraxia, is a neurodevelopmental disorder affecting motor skills, coordination, and movement in children and adults. It impacts daily activities, academic performance, and social interactions. Follow us here at Specific Learning Disorder (SLD)

Diagnostic Criteria 

To diagnose DCD, the following criteria must be met:

1. Motor skills are substantially below expected levels for age and intelligence.

2. Motor difficulties interfere with daily activities, academic performance, or social interactions.

3. Symptoms from early childhood (may not become apparent until academic or occupational demands increase).

4. Motor difficulties are not better explained by:

• Intellectual disability.
• Visual or hearing impairment.
• Motor disorders (e.g., cerebral palsy).
• Neurological conditions (e.g., stroke).
