This could have nothing whatever to do with what caused your episode, but it might be of interest, so it can't do any harm to tell you that my wife had a very similar "funny turn" last April which also turned out to be a minor stroke.
The medical profession put her through a battery of tests: blood tests, cholesterol, MRIs etc etc in an effort to explain why she'd had a stroke at a comparatively young age (late 40's). Apart from mildly elevated cholesterol, there was nothing out of the ordinary until they gave her a "bubble test" which revealed that she had a PFO (Patent Foramen Ovale) or hole in the wall between the upper chambers (atria) of her heart. It seems that there is a growing body of evidence linking PFO with what they call "cryptogenic" stroke, i.e. one whose cause is not otherwise obvious. Seemingly (and I apologise to those with greater medical knowledge if this explanation isn't 100%, I'm just trying to keep it simple) blood from one atrium is pumped to the lungs for oxygenation, and some tiny clots which may be present get lodged harmlessly in the lungs which thereby act as a filter. Thereafter it returns to the heart where the other atrium sends it off, duly oxygenated and filtered, around the rest of the body. With a PFO the unfiltered blood can get through to the "rest of the body" atrium and cause problems elsewhere, including the brain. There is also an as-yet completely unproven but very interesting-looking correlation between PFO and migraine, and an intriguing number of migraineurs who have had PFO closure operations have experienced a significant reduction in frequency and intensity of migraines, if not a complete cessation - with one caveat, of which more in a mo....
My wife had her PFO examined in greater detail with the previously-mentioned Trans Oesophageal Echocardiogram (which involves swallowing a camera) and was assessed as suitable for having her PFO closed. This was done in November with a keyhole procedure involving a pair of what I can best describe as something like a pair of small cocktail umbrellas (albeit made of a nickel-titanium alloy with a PTFE membrane) sent in via a tube inserted in the femoral artery.
Although her PFO was now closed, she seemed to have an
increase in the frequency of her migraines (from which she's suffered all her life), which was disappointing because she'd had high hopes of the closure op helping with these. We then began to investigate the possibility that she might be having a reaction to the nickel content of the closure device, (as she's always had a reaction to the nickel content of cheap jewellery - although lots of women don't get on with cheap jewellery, for many other reasons!) With some research online, it seemed that using Clopidogrel and not Persantin as the anti-platelet medication might very quickly put a stop to that; she had been put on Persantin (dipyridamole) after the stroke, and the change to Clopidogrel seems (touch wood) to have done the trick - no more migraines since. Once the body's tissue has completely grown over the PFO closure device (six months or so post-op) she may be able to come off the Clopidogrel.

As I say, all this could be completely irrelevant to you, but maybe not.
Very, very best of luck to you.
