Not all children are at the extreme far edge of problems like AS, ADHD etc, I can see that the extreme end, may need medication, but most of these children can manage in ordinary classrooms with a little help with management skills.
I have dysparaxia and probably ADHD.I got through school, went to university, had a reasonably successful career, and have been married for 50 years. DS has dysparaxia and probably ADD. He is a senior academic, an expert in his field, appears on tv half a dozen times a year because of this and again is in a long marriage. Fortunately neither of his children has either problem.
At his secondary school, his teachers recognised his problems, although not their cause within days. On the first parents evening, they told us what they did to deal with it. Each teacher was different, one wouldn't let him sit near a window, another asked him something at regular intervals, another wouldn't let him have a book on is desk and so on.
What worries me these days is that while it is great that these problems are recognised, we tend to over react to them. Most people have problems to overcome but we develop the resilience to deal with them, now we are victimising and medicating children instead of enabling them to cope with their problems.
