DEVELOPMENT OF THE
WESTMEAD PTA SCALE

Researchers at Westmead Hospital have extended the work of the Oxford group to produce the Westmead PTA Scale. It consists of 7 orientation questions and 5 memory items designed to objectively measure the period of post-traumatic amnesia (PTA).

The Westmead PTA Scale is a standardised and prospective measure of PTA and represents a move away from the subjective and retrospective estimates of the past.
