People who blame parents for this condition are ignorant, stupid, or even possibly, both. For the parent still struggling to find a reason for their child's problems, this may be difficult to accept.

ADHD - Apart from girls manifesting the symptoms differently than boys, there has also been much LESS research done on females. On top of this, the diagnostic criteria, which fits the male model of ADHD, is still used as a tool for diagnosing girls.
Boys frequently stick out more because of their boisterous, overactive behavior.
However, it's believed that ADHD is under-diagnosed in Great Britain at the present time. One reason is because parents are afraid to bring their suspected ADHD children into the doctor. Unfortunately, they're concerned about the use of stimulant medication in treating children. The media here has presented a very negative picture of that. What these people are forgetting though, is not all ADHD-diagnosed children are on medication.
