Been there, done that. Got the scars to prove it. Literally.
I was 46 when mine hit. Just one. That was enough. Caused by a PFO, as in Patent Foramin Ovali. All babies are born with a hole between the atrial chambers of their heart. It is usually healed closed soon after birth. But usually doesn't mean always. I went that far never even knowing i had it. Walked into the shop one day, and wham, whole right side shut down. I had quit drinking years before that, but I remember being what I'd call half drunk before that. But never just half, as in one side of me.
The hole had allowed a tiny clot to pass from atrial chamber to atrial chamber, straight on to the back of my brain. Tiny clots are usually filtered out in the liver and such, but with the PFO, I had a built in bypass for any filtering.
So, they hauled me to Scott and White hospital, for 8 days. Longest I had ever been in the hospital in my life. Took them a couple days to determine for sure what caused the stroke. Then we figured out that the way to fix it all, and keep it from happening again, was gonna involve open heart surgery. They do it with a catheterized device these days, but that was still experimental then. Couldn't put me on the heart lung bypass to open up my heart till the stroke site healed. That took about six weeks or so. I was on rat poison(coomaden) till that healed. There was more to that part than I'll get into now, but I went into the hospital in early Feb to do the surgery. 3 days later, I walked out. Big scar up my chest, went home for 6 weeks to let that heal. Then they turned me loose, with restrictions, to go back to work. Told me not to pick up anything over 15 pounds. I didn't tell them that the big Cat 50 mill I always ran didn't have a tool one that weighed less tan 15lbs, but I got it done, by being careful.
I was lucky. My stroke didn't leave me with any deficits. Balance wasn't quite what it used to be, but it got some better as the years have passed. That was 13+ years ago. The lack of most stroke related deficits helped a lot, plus the fact that I was out for 6 weeks recovering from the surgery is gonna be a big difference in your case and mine. I really didn't notice too much fatigue at the time. I had lost some conditioning, but it came back pretty quick.
It is likely that the decision making deficit you are experiencing is a stroke related deficit. Part of the brain that got starved for oxygen may have been the part that helps with that process. Your brain will try to find alternate paths, different synapses, to use to accomplish the job. Most of this happens in the first two weeks after the stroke. But it can be worked on and improved on later on, to a degree. The fatigue may be in the same category. Only time and your situation will tell. Keep working, try not to get frustrated, and good luck. The harder you can work on the deficits, the more progress you will make. No one can say exactly what you should or shouldn't be able to accomplish, except that the harder you work, the more progress you will make on YOUR problems. The limits have more to do with you and how you approach them than anything else. Biggest tools you have are perceverance and time. Lots of time.
