The international stats on ADHD show we have massively under-diagnosed historically. This isn't surprising because our health system, the NHS, has rationed mental health and learning difficulties healthcare to the available resources. The various thresholds are designed around capacity, not absolute clinical thresholds. Traditionally, your neurodiversity has to be so severe that you simply can't function in society, and even then you will be drip fed, delayed, and probably need to go to court to get any support.
Both my daughters have neurodiversity but our local council - one that has been repeatedly taken to court by parents and found guilty - had filtered them both out on the grounds that the school didn't find them unmanageable.
They could continue to go through life hating themselves for being different, eating disorders, suicide attempts etc.
Or I could pay out my precious, dwindling, savings to go private.
I dont believe anyone voluntarily pays thousands in private healthcare unless they are absolutely desperate.
So far I haven't taken the plunge and they are both on 6 year long waiting lists. At some point if I get the money, I would pay. But I worry that it would be discredited by that Panorama programme. So we wait.
I wonder if that one provider was just a corrupt one. I don't think they all are. I think the vast majority of people who apply do so because its absolutely self-evident to them that they have it.
That's my genuine take on it.
