Definition

When considering transient loss of consciousness (TLOC), it is the 'consciousness' component that sometimes causes difficulty. For details on a non-resolved loss of consciousness see 'Coma'. Consciousness has two components - wakefulness and awareness.

This needs to be discriminated from situations in which there is loss of tone or a fall.
