Name changed to avoid outing self.
My DH had a terrifying episode on Saturday night. He had stayed up watching TV and woke me up in the early hours by thrashing round the kitchen. I came down to tell him off
but quickly realised he wasn't really himself 
He was talking absolute jibberish, slurring his words, very clumsy, lost hand-eye co-ordination, and was really confused. He was talking to me and thought he was making sense, but actually it was just a jumble of words, most of them not even connected.
I genuinely thought he was having a stroke so called an ambulance (felt like a plonker; the person on the phone clearly thought he was just drunk but I knew it was much, much different to when he is drunk) and the paramedic who came was as bemused/concerned as I was. He did some basic tests and then called an ambulance crew to transport DH to hospital.
By the time we got to hospital (maybe an hour after the initial call?) DH was lucid but was still very confused. He kept asking me to repeat what had happened and would occasionally ramble about unrelated things.
Because he was lucid and acting relatively normally by this point we obviously weren't high up the priority list and were in A&E for hours and eventually sent home without seeing a doctor (the wait would have been more hours and the nurse recommended a rest and seeing his own GP today)
Saw GP today. He was very patient, very thorough in observing DH and listening in detail to what happened, but says we'll probably never know why it happened and should try to relax and assume it won't happen again. He's ordered some blood tests and uhm-ed and ahh-ed over whether to book a CT. In the end he hasn't booked the CT, saying the chance DH had a Mini-stroke/TIA are 'virtually nil' due to his age and otherwise good health.
I'm still concerned. I know this GP has done years and years of training. I know I should just trust him. But Saturday night was terrifying and I really, really don't want it to happen again. Everything I find online suggests that young people can and do have TIAs and that TIAs are often warning signs before a bigger stroke. WWYD? Should we go back and request the CT? (Any risks of a CT? Why wouldn't he have asked for one?) Get a second opinion? Anything else?
If you got this far, thank you
I needed to get that off my chest!
