The minds are not a battle field unit, they're not easy to reach. And wouldn't the fact that it is now brain dead mean it isn't transmitting orders or signals? So wouldn't it be considered dead or at least damaged and rebuilt?

The brain isn't dead, it wasn't damaged. It might temporarily go 'off' the hive network when the weapon fires, but afterwards, it's still there. It still has the capacity, it's still the Mind or whatever, the mental part of it is just dead. No activity or signals. More like a man who won't wake up, rather than a man whose heart just stopped.
