RA assessment should be routinely recorded in all PTA assessment. RA assessment alone therefore had significant and novel utility in post-TBI assessment. In the presence of potential in-hospital confounders including opioids, RA recovered significantly sooner after TBI than AA and was predictive of imminent AA recovery. AA recovery typically followed RA recovery with minimal delay. The scoring is based on the best eye-opening response (1-4 points), best motor response (1-6points) and best verbal response (1-5 points) with the cutoff point for coma at 8 points. The effects of a moderate or severe TBI are different for.
RA recovery preceded/coincided with AA recovery in 100% of those who recovered when AA was defined as ×3 consecutive 12/12 scores (as is current widespread practice). Glasgow Coma Scale (GCS): is a point scale used to assess a patients level of consciousness and neurological functioning after brain injury. A moderate or severe TBI may result in an extended period of unconsciousness (coma) or amnesia. Where RA recovery less frequently followed AA recovery, temporal lobe contusions were more frequent. RA recovery preceded AA recovery in 15/31 (48%), while AA recovery preceded RA recovery in 7/31 (23%) (χ 2 = 8.6, P = 0.003). The two types of amnesia you hear about most often are: Retrograde amnesia Anterograde amnesia Retrograde amnesia is basically a condition in which someone can't recall stored memories, like their mom's maiden name or what happened last Christmas, but they may recall the knock-knock joke their little brother told them a few seconds ago. While RA recovery coincided with a GOAT recovery in 19/31 (61%), AA recovery coincided with GOAT recovery in only 6/31 (19%), (χ2 = 11.5, P < 0.001). AA was primarily assessed using the Westmead PTA Scale, and RA was assessed using the GOAT. The Galveston Orientation and Amnesia Test (GOAT) represented a crude test for PTA (GOAT <75). We compared RA recovery with AA recovery in a prospective cohort post TBI. This suggests potentially significant utility with RA assessment alone since opioids are commonly prescribed post TBI. A recent study demonstrated that although AA and disorientation were both present in non-TBI inpatients uniformly taking opioids, RA was absent. However, RA is often neither assessed nor emphasized. Posttraumatic amnesia (PTA) after traumatic brain injury (TBI) comprises anterograde amnesia (AA), disorientation, and retrograde amnesia (RA).
