I searched for "autism and aging" in the NAS website and got no results.  A call to share and discuss resources on this topic.

Somewhere to start with maybe.

Autism in Middle and Old Age: What Do We Know, What Do We Need to Know? - SPARK for Autism

Here are 3 blog posts I have just found (linked to pay for courses and naturally no advocacy of same intended) however there are practical suggestions here for free for a more positive experience of being both old and autistic as well as simply describing the problems! 

Ageing and Autism – Attwood & Garnett Events

Autistic and Ageing – Part 1: When later-life changes have different o – Attwood & Garnett Events

Autistic and Ageing, Part 2: Five practical foundations for ageing wel – Attwood & Garnett Events

The first link could have been sourced from my biography.

I would love to do some of those courses but they would be addictive. I’d have to complete them all and then I’d regret spending a fortune.

Yes, it's interesting that although "every autistic person is different" that there is a sense of commonality in experience ArchaeC 

I suspect that the course would be good to go to for a variety of reasons too.  And yes they could cost a fortune.

The key strategies for a healthier later life the course suggest include rebuilding structured routines, leveraging special interests, and ensuring environmental modifications for comfort.

perhaps autistic people in later life don't necessarily need courses to think about and organise these things ourselves?

It is suggested that routines are generally good for autistic people TheCatWoman - praps tha's why we can be said to be resistant to change.  Myself i'm alright with change if i have time to consider and adjust to it - and ideally i do it on my own terms...

hehe meanwhile "au contraire" TheCatWoman  I would observe that you are one of the biggest contributors and participants to this social network :-) 

I agree that this can be engaged with more on our own terms tho' and that it can be hard work in some sorts of company.

yes "pass time with good company" :-) that's meant to be henry VIII isn't it - hehe bit late for your era of interest isn't it :-)
