Over the last few weeks I've been in touch with various friends and without exception either they or someone they're related to, have either been diagnosed with or think they have ADHD (partners / husbands / children).
I'm not doubting a for a minute that those who are undiagnosed have really good reason for thinking they have it but only those who can afford private are going to get a proper diagnosis and it seems like so many people could potentially have it that it would make sense to have a rollout of testing. I know this would be expensive but surely if there was a national testing rollout then there could be a way of making the process quicker and more efficient (and cheaper).
My brother has ADHD and was tested abroad and it was much quicker and they used something to measure his brainwaves (sorry I might've misunderstood what exactly that entailed).
Not sure if this is the answer but I really think something is needed.
