What do you call a temporary loss of consciousness?

The correct medical term for a brief loss of consciousness is syncope (pronounced SIN- cop-ee). Fainting and blackout are colloquial terms for syncope.

syncopy is fainting.. temporary loss of consciousness.

Player Teresa611, I picked syncope too.

There is a video on YouTube called "My RPG-7 Exploded on Me" from Ballistic High-Speed channel. As the title states, the weapon blows up in the shooter's face causing some serious injuries. There is a lapse of time from the moment of the explosion to the moment his mates begin to aid him, 7 to 10 seconds, of which the shooter has no recollection at all, despite being somewhat conscious for half or so of this time. It's amazing how the brain works and reacts to serious trauma.

so pregnant women blackout when they faint.....
