It doesnt really matter what the CDC uses to represent ADHD This is not the CDC its not a medical association its not a waitingroom brochure for concerned parents of hyperactive children Its an encyclopedia Whether or not the image is considered appropriate by the CDC makes absolutely no bearing on whether or not its suitable for an encyclopedia Organizations are not infallible  I trust the CDC to know the symptoms treatment and progression of ADHD I do not trust them to know how to paint a room dress a hyperactive child or illustrate an encyclopedia
