My 9 year old has just had private ASD and ADHD assessments (diagnosed to have both).
I spent a long time trying to get my head around it all as it seemed so jolly complicated to me
What I wanted was a one stop shop, that could assess for both, and then prescribe if needed initially, but it seemed that that was not an option at all (certainly not in the North West anyway)
I then realised many of the local/ online ADHD assessors could not prescribe meds if needed, so you would have to find a different team to do this, which looked like a backward step to me
I then swapped my search to an assessor who could also prescribe if she had ADHD and meds were suggested as I didn’t want to have to go back to the start
i did speak to my Gp in advance, and they said if the private assessments showed she had ASD/ ADHD to go back to them and they would then Refer on the NHS - I have no idea how long that will take though and what stage we will go into the process at.
I have been very careful to make sure that the private assessors follow nice guidance, and tried to make sure they also do the same assessments in their NHS role (managed it for the ASD but not the ADHD) as I have heard that makes it more likely for the NhS to accept the diagnosis.
She has just started meds and as above, it looks to be going to cost me a small fortune in getting her titrated onto the right dose etc but we are very fortunate to be able to manage that for now.
I rang our travel insurance between getting the ASD diagnosis and ADHD one as we were going abroad last week. Despite ADHD not being something we apparently needed to declare (ASD was), they wouldn’t ok the travel insurance until we had the assessment back for that as she was ‘under investigation’. Thankfully we had our final assessment the day before we flew and they did ok it. They did ask me lots of questions about when we had first started the referral process in relation to booking the holiday though, so it is possible if you have already made an appointment for an assessment, even if you delay it, the private healthcare MAY consider that in their judgement, but we don’t have private healthcare so I may well be wrong
Good luck, it is a total minefield and really stressful
