![]() ![]() Occupational therapy intervention based upon the PRPP System of Task Analysis and Intervention improved subjects' ability to apply information processing strategies during occupational performance when compared to current intervention approaches. Amnesia, in the Greek language, means forgetfulness. If you have amnesia you may be unable to recall past information (retrograde amnesia) and/or hold onto new information (anterograde amnesia). Subjects demonstrated improved information processing strategy use both prior to and following emergence from PTA. Overview What is amnesia (amnesiac syndrome) Amnesia is a dramatic form of memory loss. Large treatment effects favoured the PRPP Intervention. Seven subjects significantly improved in their application of processing strategies during the PRPP Intervention in comparison to current OT Intervention phases. Post traumatic amnesia (PTA) is a period of cerebral malfunction following brain injury during which a person is confused and unable to establish continuous. PRPP Intervention adopts an information processing approach that simultaneously focuses on task training, strategy training and strategy application within occupational performance. The PRPP System is a dynamic assessment and intervention approach that directly links results of cognitive task analysis with strategies for intervention. PTA status was monitored with the Westmead PTA Scale. ![]() Information processing capacity during occupational tasks was measured using the PRPP System of Task Analysis. Current OT intervention was alternated with the experimental Perceive, Recall, Plan and Perform (PRPP) System approach over 4-weeks. Single-system experimental design (ABAB) across subjects.Įight subjects were recruited during acute rehabilitation. All rights reserved.To investigate the effectiveness of occupational therapy (OT) with adults demonstrating agitation and post-traumatic amnesia (PTA) following brain injury. ![]() We review the literature regarding PTA and, in particular, the continued role of the WPTAS in directing neurosurgical practice.Īgitation Confusion Post-traumatic amnesia.Ĭrown Copyright © 2013. Currently, the Westmead PTA scale (WPTAS) directs most in-hospital TBI management throughout Australasia: however, in addition to general defects, specific limitations have been identified in the levels of evidence for WPTAS validity. Although all of these features were fully described (or implied) by the earliest pioneers, most current PTA scores do not assess the complete "post-TBI syndrome". While it can be concerning, this is actually a phase in which the brain is healing. Signs of post-traumatic amnesia can include confusion, impaired memory, and unusual behavior. Recently, impairments in attention and executive functioning have also been emphasised indeed, some consider these the primary disturbance with PTA. Post-traumatic amnesia is a common stage after a brain injury where the survivor struggles with memory, especially when emerging from a coma. More instructively, the complete "post-TBI syndrome" also comprises an extensive cognitive deficit which includes a confusional state, as well as a behavioural disturbance characterised by acute agitation. ![]() Whilst anterograde memory is certainly disrupted in PTA, PTA in fact involves a far more extensive memory disturbance. Accurate PTA assessment is important, because over-evaluation leads to excess social, financial and opportunity costs, whilst under-evaluation risks patient welfare. Despite the lack of a consistent definition, PTA is widely used as a construct in neurosurgical practice to guide decision-making and prognosis. Of patients hospitalised for traumatic brain injury (TBI), most pass through a state of altered consciousness known as "post-traumatic amnesia" (PTA). ![]()
