The paper describes a clinical case of applying a set of computer-based stimulation programs for cognitive impairment arising from severe open traumatic brain injury (TBI). It demonstrates the rehabilitation capabilities of a set of «Neurotechnology+» stimulation programs for correction of cognitive deficits in patients with dysregulated moderate cognitive impairment resulting from experienced severe open TBI. It is noted that the use of a set of the programs contributed to the improvement of impaired regulatory and neurodynamic functions, the expansion of phonemic and semantic speech activity, and the improvement of memory processes. The described case suggests that computer-based cognitive training has a positive impact on cognitive recovery after post-traumatic brain injury.

AbstractThis study examines rates of reporting of new or worse post-traumatic symptoms for patients with a broad range of injury severity at 1 month and 1 year after traumatic brain injury (TBI), as compared with those whose injury spared the head, and assesses variables related to symptom reporting at 1 year post-injury. Seven hundred thirty two TBI subjects and 120 general trauma comparison (TC) subjects provided new or worse symptom information at 1 month and/or 1 year post-injury. Symptom reporting at 1 year post-injury was compared in subgroups based on basic demographics, preexisting conditions, and severity of brain injury. The TBI group reported significantly more symptoms at 1 month and 1 year after injury than TCs (each p < .001). Although symptom endorsement declined from 1 month to 1 year, 53% of people with TBI and 24% of TC continued to report 3 or more symptoms at 1 year post-injury. Symptom reporting in the TBI group was significantly related to age, gender, preinjury alcohol abuse, pre-injury psychiatric history, and severity of TBI. Symptom reporting is common following a traumatic injury and continues to be experienced by a substantial number of TBI subjects of all severity levels at 1 year post-injury.

Comorbid post-traumatic stress disorder with traumatic brain injury (TBI) produce more severe affective and cognitive deficits than PTSD or TBI alone. Both PTSD and TBI produce long-lasting neuroinflammation, which may be a key underlying mechanism of the deficits observed in co-morbid TBI/PTSD. We developed a model of co-morbid TBI/PTSD by combining the closed head (CHI) model of TBI with the chronic variable stress (CVS) model of PTSD and examined multiple behavioral and neuroinflammatory outcomes. Male C57/Bl6 mice received sham treatment, CHI, CVS, CHI then CVS (CHI → CVS) or CVS then CHI (CVS → CHI). The CVS → CHI group had deficits in Barnes maze or active place avoidance not seen in the other groups. The CVS → CHI, CVS and CHI → CVS groups displayed increased basal anxiety level, based on performance on elevated plus maze. The CVS → CHI had impaired performance on Barnes Maze, and Active Place Avoidance. These performance deficits were strongly correlated with increased hippocampal Iba-1 level an indication of activated MP/MG. These data suggest that greater cognitive deficits in the CVS → CHI group were due to increased inflammation. The increased deficits and neuroinflammation in the CVS → CHI group suggest that the order by which a subject experiences TBI and PTSD is a major determinant of the outcome of brain injury in co-morbid TBI/PTSD.

AbstractThe prevalence and nature of post-traumatic stress disorder (PTSD) following mild traumatic brain injury (MTBI) is controversial because of the apparent paradox of suffering PTSD with impaired memory for the traumatic event. In this study, 1167 survivors of traumatic injury (MTBI: 459, No TBI: 708) were assessed for PTSD symptoms and post-traumatic amnesia during hospitalization, and were subsequently assessed for PTSD 3 months later (N = 920). At the follow-up assessment, 90 (9.4%) patients met criteria for PTSD (MTBI: 50, 11.8%; No-TBI: 40, 7.5%); MTBI patients were more likely to develop PTSD than no-TBI patients, after controlling for injury severity (adjusted odds ratio: 1.86; 95% confidence interval, 1.78–2.94). Longer post-traumatic amnesia was associated with less severe intrusive memories at the acute assessment. These findings indicate that PTSD may be more likely following MTBI, however, longer post-traumatic amnesia appears to be protective against selected re-experiencing symptoms.

Traumatic brain injury (TBI) is often associated with cognitive impairments. The psychological sequelae of cognitive deficits and emotional problems contribute significantly to the disability in the patient and to the distress of the family. The study aimed to develop a cognitive retraining programme to enhance cognitive functioning in TBI. 25 years old male presenting with history of left temporal hemorrhagic contusion with cerebral edema underwent 2 months of a cognitive retaining programme, addressing executive functions impairment. A single case experimental design with pre- and postassessment was adopted to evaluate changes in the patient in response to the intervention. Improvements were found in cognitive functioning, and in symptom reduction and behaviour. The 2 months hospital based cognitive retraining programme was found to be efficacious in ameliorating symptoms and improving cognitive, social and occupational functioning post traumatic brain injury.

ObjectivesTo estimate the prevalence of post-traumatic stress disorder (PTSD) in a large civilian population with traumatic brain injury (TBI), and to assess whether brain injury severity is correlated with PTSD symptoms.DesignObservational, cross-sectional study.Setting and participantsOutpatient clinic in a major UK trauma centre and secondary care hospital. Estimates of PTSD prevalence are based on 171 sampled individuals attending TBI clinic within an 18-month period. Analysis of the relationship between TBI severity and PTSD was performed on the subset of 127 patients for whom injury severity data were also available.MethodsCivilian TBI clinic attendees completed validated self-report questionnaires assessing PTSD (PTSD Checklist Civilian Version (PCL-C)) and other psychiatric symptoms. From this, the prevalence of PTSD was estimated in our cohort. Postresuscitation Glasgow Coma Score and Marshall grade on CT brain scan were recorded as indicators of brain injury severity. A hierarchical regression explored whether TBI severity may predict PTSD scores.ResultsA high prevalence of PTSD was estimated (21% with PCL-C score >50). Higher Marshall grading displayed a slight negative correlation with PTSD symptoms. This statistically significant relationship persisted after confounding factors such as depression and postconcussion symptoms were controlled for.ConclusionsPTSD and TBI frequently coexist, share antecedents and overlap in their resultant symptoms. This complexity has given rise to conflicting hypotheses about relationships between the two. This research reveals that PTSD is common in civilians with TBI (adding to evidence drawn from military populations). The analysis indicated that more severe brain injury may exert a slight protective influence against the development of PTSD—potentially by disrupting implicit access to traumatic memories, or via overlapping neuropsychiatric symptoms that impede diagnosis. The association suggests that further research is warranted to explore the reuse of routine clinical and neuroimaging data—investigating its potential to predict risk of psychiatric morbidity.

Post-traumatic headache is common after pediatric traumatic brain injury and affects thousands of children every year, but little is known about how headache affects recovery after traumatic brain injury in other symptom domains. We aimed to determine the association between headache and other common symptoms after pediatric traumatic brain injury and explore whether subjective complaints of headache are associated with objective deficits on specialized neurocognitive testing. We conducted a retrospective cohort study of children ages 3-19 years following traumatic brain injury with a completed Sports Concussion Assessment Tool (SCAT) questionnaire. Post-traumatic headache was defined by a score more than 2 on the SCAT question for headache and define headache groups for comparison. In our cohort, we analyzed data from the Delis-Kaplan Executive Function System and the Wechsler Abbreviated Scale of Intelligence, Second Edition (WASI-II). Headache was reported in 40 (33%) patients presenting for post-traumatic brain injury care among 121 pediatric traumatic brain injury patients and did not differ by injury severity. Median total SCAT symptom score in the headache group was 5-fold higher compared to patients without headache (median 45.5 vs 9; P < .001). Significantly lower-scaled scores in color naming, matrix reasoning, letter sequencing, and letter switching were also found in the headache group (all P ≤ .03). Our study shows that headache, as reported by patients on the SCAT, is associated with higher symptom scores in all other symptom domains, including sleep, mood, sensory, and cognitive. Headache was also associated with worse objective neurocognitive measures and may identify patients who could benefit from specialized follow-up care and management.
