Westmead Post-Traumatic Amnesia Scale
The Westmead Post-traumatic Amnesia Scale (WPTAS) is a brief bedside standardised test that measures length of post-traumatic amnesia (PTA) in people with traumatic brain injury. It consists of twelve questions that assess Orientation (mental), orientation to person, place and time, and ability to consistently retain new information from one day to another. It is administered once a day, each and every day, until the patient achieves a perfect score across three consecutive days, after which the individual is deemed to have emerged from post-traumatic amnesia. PTA may be deemed to be over on the first day of a recall of 12 for those who have been in PTA for greater than four weeks.Tate, R. L., Pfaff, A., Baguley, I. J., Marosszeky, J. E., Gurka, J.

Post-traumatic Amnesia
Post-traumatic amnesia (PTA) is a state of mental confusion, confusion that occurs immediately following a traumatic brain injury (TBI) in which the injured person is Orientation (mental), disoriented and unable to remember events that occur after the physical injury, injury. The person may be unable to state their name, where they are, and what time it is. When continuous memory returns, PTA is considered to have resolved. While PTA lasts, new events cannot be stored in the memory. About a third of patients with mild head injury are reported to have "islands of memory", in which the patient can recall only some events. During PTA, the patient's consciousness is "clouded". Because PTA involves confusion in addition to the memory loss typical of amnesia, the term ''"post-traumatic confusional state"'' has been proposed as an alternative. There are two types of amnesia: retrograde amnesia (loss of memories that were formed shortly before the injury) and anterograde amnesia (pr ...
