Measurement and definition of post traumatic amnesia - an international perspective

This study will examine the definition and measurement of post traumatic amnesia around the world. Post traumatic amnesia is a period of confusion, disorientation and anterograde amnesia that occurs following traumatic brain injury (TBI). Although PTA is commonly used as an indicator of injury severity, there is much variation in how PTA is measured and defined. Through dissemination of an online survey, this study will seek to explore how PTA is measured and defined in different countries. This is a critical first step in promoting consistency in definition and measurement - which allows for better synthesis of research findings internationally. The study will also examine, as a secondary outcome, the medical prescribing practices for neurobehavioural symptoms during PTA.
