-dyscalculia - mathematics
Motor Disorders - Neurodevelopmental Disorders
-motor coordination is below expectations based on age/intelligence and when
coordination problems significantly interfere with functioning
3 Major types of motor disorders? - 1. Developmental coordination disorder: impaired
development of motor coordination (delays in crawling, walking, dropping things, poor
sports performance)
2. Stereotypic movement disorder: repetitive motion activity (head banging, body
rocking)
