What? Never in my life have seen charges like that. Cheapest ADHD assessments are around £400-650 mark ans if you want combined assessment with ASD it’s another £600 on top. This is for adults. For children private charges are way higher. But there is no incentive for companies to make up diagnoses.. the money is paid for assessment - not for a diagnosis. They have their money either way.
But as for the flippant ‘May as well assess for other’ comment.. most neurodivergent conditions come with others. And for ADHD, ASD is often comorbid. And you have dyslexia, dyscalculia etc. if someone has one, it is sensible to screen for others especially if a child and it will help them in their education.
And yes. More people are coming forward looking to find out why they struggle, and feel different, and think neurodivergence could be it. For decades women & girls were ignored and doctors believed children grew out of ADHD. Whilst people just learnt to mask. Social media brings awareness but diagnosis is still needed from a psychiatrist to be NHS approved. And one has to have varied symptoms, and evidence from before the age of 12.
I got to 48 until I received my diagnosis and it really explains all of my struggles.. medication for ADHD is amazing for me. I cried the first time it wore off, when I realised how I my life could’ve been so different - had I been diagnosed and medicated as a teen.
Unfortunately NHS being cash strapped in many areas is now refusing to see adults like me, and focussing on children only… making people to pay for private assessment, and medication, as getting shared care from GPs is difficult. All the best for OP in this vital service!
