He suddenly couldn't speak in space. NASA astronaut says his medical scare remains a mystery

The astronaut who prompted NASA's first medical evacuation earlier this year said Friday that doctors still don't know why he suddenly fell sick at the International Space Station.

Just wanted to clarify: Here "space" means merely 300km above earth's surface and not thousands or millions.
Even 300km is very difficult to survive (space station's zero gravity, etc.)

Zero g. Stroke, or TIA. Right?

Isn't a TIA just a stroke that's small enough to be invisible on imaging?

My dad had a TIA, and this certainly sounds similar.

Could be a high energy particle damaging brain?
