Glasgow Coma Scale
The AWPTAS, derived from the Revised WPTAS, includes the five verbal orientation items from the Glasgow Coma Scale (GCS) and three picture cards used to measure memory. The RWPTAS has been shown to be more accurate than the Glasgow Coma Scale in the identification of cognitive deficits in patients with mild TBI. The A-WPTAS is administered hourly rather than daily. It is used for measuring the length of PTA following a mild traumatic brain injury (that is, when PTA is less than 24 hours).
