Pervasive developmental disorder ADHD PDD Asperger

From Jeena Yahan 2011 Brochure

The number of children with PDD and ADHD is difficult to determine because children with PDD alone often have elements of impulsiveness and hyperactivity. A child with PDD may also have mental retardation, but even if he does not, his PDD is likely to prevent him from participating fully socially and in many school and home activities.
