I would agree with this for some children.
For others I know who’ve been diagnosed, the Army would be an excellent career for them. Structure, loads of physical activity and routine. I remember teaching a child who’d been diagnosed about 20 years ago. He thrived on all the approaches designed for autism (which my autistic pupils ignored and avoided), structure, short learning approaches, tangible rewards, physical activities etc. we were told his father repeat offended petty crimes in order to return to prison - craving routine, structure. It’s thought many in prison probably have adhd. Doesn’t excuse the crimes but could mean that better support earlier in life might have helped. (I’m in favour of the government’s approach for more physical routes in education.)
diagnosis is a double edged sword.
I would prefer a diagnosis of executive function difficulties and then a profile which pin points the specific difficulties the individual has. And then all manner of interventions- some physical eg OT/ physio , some routine based, and in certain circumstances, for those who really can’t filter and focus, medication.
It does get extremely difficult when a child is living in a chaotic home where the parents are also really struggling. It’s hard to tell in those circumstances what is causing the executive function issues; environment or if it’s their own health.
Sometimes the parents have extreme adhd, medical and mental health issues. It’s clearly heritable. But also trauma and chaotic home life can impact. It matters from the pov of medicalisation, does the child need a more stable background or would the child benefit from medication ?
An often ignored symptom is haphazard exhaustion. Falling asleep randomly. And extreme swings of emotions. Children becoming exceptionally angry very quickly and loosing their tempers. However, if you’ve had disrupted sleep and are experiencing parental swings of emotion in similar fashions, is the child likely to be being affected by their environment?
The condition definitely exists; one just spent a year with several children who are autistic but varying levels of ability to focus and filter and impulsive sensory seeking behaviours make teaching very challenging. Some are awaiting adhd diagnosis but the only reason is to see if meds might help. The one who was medicated has made the most progress but alongside an awful lot of environmental approaches too.
