Neurodevelopmental disorders are conditions that affect the functionality of the brain. With many neurodevelopmental disorders, the signs and symptoms most often begin to show when a child is young, usually around preschool years.

Family dynamics and school considerations are also included with these cases given the ages of the clients. Questions for consideration are included.
