I had a stroke in 2015. I was 32. We were getting ready to go meet friends for a playdate with our toddlers and as I was about to put on my jacket, I felt the weirdest sensation of my right arm just somehow disappearing. I turned around to tell my husband that something weird happened and then realised I could not speak. That made me realize I was having a stroke.He realized something was wrong, panicked, asked me if I was having a heart attack. I was able to use my working arm to point to the head. By that point also some slurred speech was possible so I could tell him to call an ambulance.By the time the ambulance arrived my symptoms disappeared and they were rather skeptical because a stroke is not the most likely explanation at that age. But they took me to the hospital anyway where an MRI confirmed a stroke.Long story short, it has been 4 years now and no cause could ever be identified. Not for the lack of trying, they've tested me for every super rare thing the neurologist could think of over these past few years.
However, I am sure your doctors will tell you as they told me (f they don't, searching pubmed can), as scary as it is, not being able to find a cause actualy gives you the best prognosis, especially when you are young (and 47 is also young for stroke statistics).The subgroup of stroke victims with no known cause has best survival and recovery statistics.
Sometimes now when I raise this issue with some random doctors they're rather dissmissive (as in, you're alive 4 years later, it barely counts) and I always feel mildly annoyed, but also a little bit relieved because as annoying as it bloody is to have a doctor dissmiss such a massive traumatic health event, it also feels better than being met with horror and fear that you will die in front of them if they do something wrong (which was very common when I got pregnant in 2016).
I'm sorry this happened, from my experience I would say don't underestimate the psychological toll this will take when it sinks in and consider getting psychotherapy as soon as possible. I first wanted to be all "now I will know to appreciate life" but it developed differently, I became very anxious and depressed and had clear PTSD signs from it. Don't read too much on google, there is way too much shit that will scare you out there, you need to really understand statistics and epidemiology if you want to read that stuff (I used to work in this field and I understand all those things but it is still difficult to think rationally about it all when depression and anxiety kick in).
Just remember, not finding a cause is not a bad outcome in terms of prognosis.
Good that you are FIRE...to be honest the biggest concrete influence any of this now has on my life is, well, goodbye private medical/life insurance. But we were also financially super responsible way before this happened and we can manage to face any future without insuring me extra over what is state provided (we're in Europe so there is less weird stuff about healthcare around here, thank God).
