If anything, I think fighter pilots have a more strenuous experience than astronauts. They have to deal with intense fluctuations between high and low Gs, and I imagine that cannot be very healthy for the brain.

Astronauts do experience relatively high Gs during launch, but nowhere near what fighter pilots experience during high maneuverability exercises - and after a brief launch, the rest of their mission is entirely in 0G.
