Background: MIL, 70, was diagnosed with vascular dementia just before Christmas. She has been declining but still knows who we are, which is great. Very poor short-term memory, a little bit snappy, has wandered off once, sometimes forgets who FIL is or doesn't believe him when he says things, so tough for him.
They live 130 miles from us. SIL is a 5-minute drive from them & doesn't work & only has teens at home, so helps out a lot.
DH is currently working full-on days (gone from home about 14 hours/day or more), but is in a contract with 6 more weeks to run. Also does football training most weekends & has just gone on Parish council. I work a few hours a week as am mainly SAHM to our 3 DC, 8-year old DS2 has moderately severe autism (think 32.5 hours/week support in mainstream school). We have 1 car for the household.
Anyway, I think that's all background, trying not to drip feed. DH got a message about 2 hours ago from SIL to say MIL was really out of it & they took her to doctors. Doctor said infection but also possibly stroke. They are currently in hospital waiting to be seen, have been prioritised. MIL is apparently a bit better, very sleepy, high temperature & BP.
Understandably, DH is very worried but feels helpless. He was at work when he got the message, on his way home now & awaiting more news.
I don't know how to support him! Have said go to them if he needs to, I can handle things at home etc. In reality I will struggle, especially without car, but his mother takes priority I feel & I would never let on if I do struggle.
We saw them this weekend & she seemed ok, lots of repeating stuff but also fairly alert & happy. So this has come as a shock to us both.
Can anybody suggest anything I can/should do? Or does anybody have any experiences of having a stroke after being diagnosed with vascular dementia? Everything I read on Google talks about stroke being a cause of vascular dementia not vice versa 
Anyway, sorry for rambling & thanks for reading if you got this far. I just feel so helpless
