I really don't think thats accurate. I think for DLA its considered a 'mental condition'. FWIW, I don't think its either. I know you arent asking me specifically, but it doesn't bare any relevance to me on whether I think some children should get benefits. Or adults. I think the diagnosis shouldn't - as it doesn't for PIP - I do think the struggles one may have should though. And that is very person-centric.
Someone asked me about levels earlier - I forgot who sorry. I worked in oz for sometime where they did and still do, and here they don't. I agree wholeheartedly with the system here. Levels are quite confusing and ableist in my view and not terribly helpful. Someone can be thriving academically, in work and socially, for example, but struggle deeply with everyday tasks. Spiky profiles are common.
Also, someone asked about how you separate trauma, menopause, ADHD and Autism. It really isn't easy as there are lots of crossovers. Thats why it takes hours and hours of assessments, discussion with MDT, gathering information and history. We need to know we aren't missing something or misdiagnosing. As I said before, trauma and menopause/puberty commonly increases symptoms of adhd/autism anyway, so it often doesn't mean its something else it just means thats when it becomes a greater struggle for the person. Things getting better later, maybe due to a lifechange, or the correct scaffolding for that person, doesn't mean the diagnosis wasn't correct. For example, a person with adhd in the wrong job for them without support could be really really struggling, then they find the right job for them witht he right support and that improves their mental health and wellbeing and they appear to be 'cured'. They aren't cured they just have the right set up for them.
