I do agree with some of this post.
It's always a good idea to exclude any other common causes before jumping to a conclusion.
And because ADHD is such an on-trend subject right now, I'm aware that there's the risk of people jumping to conclusions. The difficulty with autism and ADHD is that some of the traits can be experienced by NT folk. This leaves it open to the whole "oh, everyone is a little bit ADHD because we're ALL like that." It's a really frustrating argument to have to battle against.
I think the key things here are the intensity of the symptoms. For example, losing things isn't unique to ADHD but literally, if I don't have a specific place to put something I have to walk around with it in my hand or else there's a very good chance it will be lost forever.
The ADHD symptoms can sound generic but it's the severity of the symptoms and the extent to which they disrupt your life. Regularly forgetting where you put your keys is not the same as losing every single thing you have and struggling to keep track of literally everything. All of the time. I can lose things without even getting up out of the chair or moving my feet!
The other thing is the constancy of the symptoms. If these symptoms are new, or just appear during the menopause, then it's unlikely to be ADHD.
While the menopause can exacerbate ADHD symptoms, they don't just appear out of the blue. It's one of the indicators for diagnosis - the symptoms have to be present since childhood and be omnipresent. A thyroid disorder or the menopause will present as new symptoms.
Last thing is the wide-ranging symptoms. Some people might tick off a few of the symptoms. They may even experience one or two of the symptoms to a significant degree. However, with ADHD you will have wide-ranging symptoms that cover a whole list of different aspects, it's not just isolated to one or two elements of the diagnostic criteria.
And all of this is why diagnosis is so bloody hard. Especially in women as our presentation can be very hard to spot. And please don't take this the wrong way, @Willyoujustbequiet but the fact you were assessed doesn't mean you don't have ADHD. If your child has it and you genuinely tick off all of the things on the ADHD list of symptoms that you mention, there is a very good chance that the person you saw just isn't expert enough in identifying the presentation in women. It's a fairly common problem, especially via the NHS route as they don't use experts in neurodivergent women.
I should probably add for clarity that I have ADHD and I'm also autistic, diagnosed in my 40s.
How are you with time-keeping OP? I couldn't see a reference to that (unless I missed it).
