Several recent studies have shown that hyperbaric oxygen (HBO₂) therapy carry cognitive and motor therapeutic effects for patients with acquired brain injuries. The goal of this study was to address the specific effects of HBO₂ on memory impairments after stroke at late chronic stages. ⋯ Although further research is needed, the results illustrate the potential of HBO₂ for improving memory impairments in poststroke patients, even years after the acute event.

Prospective monitoring of posttraumatic amnesia (PTA) is recommended following moderate to severe traumatic brain injury (TBI). However, few studies have examined the typical order in which items recover on PTA scales. Different methods have been used to define recovery, and the order reported is not consistent across the literature. The purpose of this study was to improve understanding of the progression of PTA by reporting the duration to recovery of items and categories on the Westmead Post-Traumatic Amnesia Scale (WPTAS) according to different criteria. ⋯ The traditional view of PTA recovering in the order of person, place, time, and memory does not adequately describe the profile of recovery on the WPTAS. Considering the recovery of individual items is necessary to understand and account for individuals differences in the order of recovery.

Few studies have examined whether psychological distress and pain affect cognitive functioning in the acute to subacute phase (up to 30 days postinjury) following mild traumatic brain injury (mTBI). The current study explored whether acute posttraumatic stress, depression, and pain were associated with performance on a task of selective and sustained attention completed under conditions of increasing cognitive demands (standard, auditory distraction, and dual-task), and on tests of working memory, memory, processing speed, reaction time (RT), and verbal fluency. ⋯ Acute posttraumatic stress and pain show strong associations with selective and sustained attention following mTBI.
