Ash8, try to get my name correct - there is no F in the term, these disorders have been thoroughly researched by many eminent professionals for decades.
I am not sure just how many parents you know currently, but whilst there will always be some who are poor at caring, many are driven to distraction by their child's seeming inability to settle and fit in and learn, with correct diagnosis and help within school, many are seeing remarkable results.
This attitude is tired, knee jerk and old fashioned and whilst you are entitled to it, I am allowed to challenge it politely I hope.
