In the context of 'Learning Disabilities', what primary functional impairment in the neurological system of children with 'Developmental Dyspraxia' affects their gross and fine motor skills the most?

In the context of child development and pedagogy, Developmental Dyspraxia is a neurodevelopmental motor disorder.

Key Characteristics:

• It primarily occurs due to a lack of proper information exchange and neurological coordination between the motor cortex, basal ganglia, and cerebellum.
• Children affected by this condition experience severe difficulty in planning and executing voluntary muscle movements (such as tying shoelaces, writing, buttoning shirts, or maintaining balance), despite having completely normal general intelligence.
