Review Meta AnalysisSurgical Outcomes in Post-Traumatic Temporal Lobe Epilepsy: A Systematic Review and Meta-Analysis.
Epilepsy surgery provides excellent benefits in post-traumatic epilepsy of the temporal lobe (PTE-TL), but outcomes relative to non-traumatic epilepsy of the temporal lobe (NTE-TL) are less favorable. Large well-designed studies are recommended to further clarify the role of epilepsy surgery in PTE. It is unclear whether epilepsy surgery outcomes in PTE are as robust as described for drug resistant epilepsy (DRE) in general. ⋯ Of 3669 articles that reported surgical outcomes in epilepsy, nine studies (n = 886) were identified that reported outcomes for both PTE-TL (n = 219) and NTE-TL (n = 667). The weighted proportion of favorable outcomes (Engel Class I) were high for both PTE-TL (70.1%, 95% CI 61.9%-78.3%) and NTE-TL (75.2%, 95% CI 69.4%-80.2%). Patients with PTE-TL were at greater risk of unfavorable (Engel Class II-IV) outcomes (relative risk 1.36, 95% CI 1.04-1.78) compared with NTE-TL.

Head Injury due to Intimate Partner Violence: Injury Characteristics, Subacute Symptoms, and Receipt of Care.
Women survivors of intimate partner violence (IPV) have increased risk of repetitive neurotrauma in their lifetime but have received less research focus compared with populations of athletes, veterans, and emergency department patients. The current study examined the importance of IPV as a contextual mechanism of injury, by comparing women survivors of IPV based on whether they experienced a head injury due to IPV or a head injury not due to IPV. The analyses involved archival data from in-person interviews conducted with women who received a protective order against an intimate partner in Kentucky from 2001 to 2004 (n = 641). ⋯ Among women survivors of IPV, those reporting IPV-related head injuries reported greater subacute symptoms, but a lower likelihood of being hospitalized or receiving rehabilitative care. Women with self-reported IPV-related head injuries represent an underserved population that is often unevaluated following injury and may have many unmet care needs. Future studies should examine persistent symptoms following IPV-related head injuries and interventions that would be most beneficial for this population.

Intimate partner violence and other trauma exposures in females with traumatic brain injury.
We examined whether females with a history of traumatic brain injury (TBI) and intimate partner violence (IPV) have greater exposure to lifetime trauma relative to females with TBI but no IPV history. Further, we assessed the effects of lifetime trauma on psychological outcomes after TBI. Female participants (n = 70; age M [standard deviation-SD] = 50.5 [15.2] years) with TBI (time since injury median [interquartile range -IQR] = 10.2 [5.3-17.8] years) completed a structured assessment of lifetime history of TBI, including an IPV module to query head injuries from physical violence by an intimate partner. ⋯ Exposure to all three sources of trauma (ACEs, CV, and IPV) was associated with worse PTSD symptoms relative to fewer traumas. The results highlight the scope of traumatic exposures among TBI survivors and the importance of considering IPV and other lifetime trauma exposure in assessing and managing TBI. Trauma-informed interventions that are modified for TBI-related impairment may offer improved outcomes in managing psychological symptoms.

Tau imaging in late traumatic brain injury: a [18F]MK-6240 PET study.
Epidemiological studies have identified prior traumatic brain injury (TBI) as a risk factor for developing Alzheimer's disease (AD). Neurofibrillary tangles (NFTs) are common to AD and chronic traumatic encephalopathy following repetitive mild TBI. However, it is unclear if a single TBI is sufficient to cause accumulation of NFTs. ⋯ Within the TBI group, One Touch Stockings problem solving and spatial working memory (executive function), reaction time (attention), and Mini-Mental State Examination (MMSE) (global cognition) were associated with [18F]MK-6240 SUVR. We found no group-based increase of [18F]MK-6240 brain uptake in patients scanned at least 2 years after a single TBI compared with healthy volunteers, which suggests that no NFTs are building up in the first years after a single TBI. Nonetheless, correlations with cognitive outcomes were found that warrant further investigation.

Application of delayed contrast extravasation MRI for depicting subtle blood-brain barrier disruption in a traumatic brain injury model.
The blood-brain barrier (BBB) is composed of brain microvasculature that provides selective transport of solutes from the systemic circulation into the central nervous system to protect the brain and spinal microenvironment. Damage to the BBB in the acute phase after traumatic brain injury (TBI) is recognized as a major underlying mechanism leading to secondary long-term damage. Because of the lack of technological ability to detect subtle BBB disruption (BBBd) in the chronic phase, however, the presence of chronic BBBd is disputable. ⋯ Cumulative evidence from recent years points to BBBd as a central component of the pathophysiology of TBI. Therefore, it is expected that routine use of highly sensitive non-invasive techniques to measure BBBd, such as DCM with advanced analysis methods, may enhance our understanding of the changes in BBB function after TBI. Application of the DCM technology to other CNS disorders, as well as to normal aging, may shed light on the involvement of chronic subtle BBBd in these conditions.
