Back when she processed the 9.3TB equation, Anna mentioned that she was relieved the neural tissue wasn't damaged since that always leads to loss of some memories for her. Based on that, she'd likely at least suffer complete amnesia if her head was destroyed.
That said, if it was a decapitation strike and the head itself survived, I suspect she'd just plug it back on with her Impeller. We've seen her create water pipelines and distribute electricity during her first construction mission, the same principles could be used for re-connecting her brain.
