I'm not sure that it does. My psychiatrists over the years and my sister have described me as very intelligent . However I have much lower non-verbal than verbal intelligence. I struggle with day to day practical tasks. I get quite a bit of help from my stepdaughter and someone who comes in twice a week to clean. The help is described in my care plan as enabling me to continue living independently in my flat.
I was diagnosed very recently and apparently DSMV doesnt use low and high functioning any more - they say you're either level 1 (needs support), level 2 ( needs substantial support) or level 3( needs very substantial support). That makes more sense to me.
High functioning never really made sense to me either. In my case would that be describing tne person who (just about) manages to hold down a professional job. Or would that be the person who is then so tired they need to sleep most of the weekend, that is completely bewildered by the local shop changing the till layout, has put up with a loo seat that falls off for more than a year because they cant quite get it together to sort a new one (true story!). The person that cant sleep without their childhood teddy bear at the age of 40 something, or like you, descends into total chaos without someone else to clean the house!
That's interesting. I was diagnosed late last year and wasn't given a high/low functioning or a number. Just an asd diagnosis. Those levels make a lot more sense. There still might be the odd person where it's difficult to place them due to varying needs but it definitely makes more sense than high and low.
I also sound similar to you. I have a job but spend much of my evenings/weekends sleeping. I end up living with issues that could be easily fixed for no good reason. I can't keep my flat tidy to save my life. I also sleep with my childhood teddy although I'm not quite 40 yet.
I didnt actually get a number either, just ASD. Im assuming level one based on the fact I survive without a lot of support except for some adjustments at work and a cleaner. On the other hand that is 'low support gets', not necesarily 'low support needs'...
I would be level 1 I'm sure because I manage on my own. Ok my flat is an absolute tip but I do tidy it eventually. There are other things I struggle with but I muddle through.
My question mark is when something happens that causes me to melt down I struggle to function at all.
