Objective: To explore functional connectivity after intensive attention training in the chronic phase after traumatic brain injury as clinical evidence indicates that intensive attention training improves attention dysfunction in persons with traumatic brain injury.
Design And Subjects: A case series study. Two young adults, 13- and 18-months post traumatic brain injury, with traumatic brain injury induced attention deficits were assigned to 20 h of intensive attention training and neuroimaging.
Methods: Functional magnetic resonance imaging during a psychomotor vigilance test was conducted pre- and post-intervention.
Results: The neuroimaging indicated both increased and decreased connectivity density in frontal, posterior and subcortical brain regions, for some regions with separate change patterns for left and right hemisphere respectively, and an overall reduction in variability in functional connectivity.
Conclusion: The changed and decreased variability of functional connectivity in various brain regions, captured by fMRI during a psychomotor vigilance test after direct attention training in a small sample of persons with traumatic brain injury, suggests further studies of functional connectivity changes in neural networks.

The conserved MAP3K DLKs are widely known for their functions in synapse formation, axonal regeneration and degeneration, and neuronal survival, notably under traumatic injury and chronic disease conditions. In contrast, their roles in other neuronal compartments are much less explored. Through an unbiased forward genetic screening in C.

Introduction: While cerebral amyloid angiopathy is likely responsible for intracerebral hemorrhage (ICH) occurring in superficial (grey matter, vermis) cerebellar locations, it is unclear whether hypertensive arteriopathy (HA), the other major cerebral small vessel disease (cSVD), is associated with cerebellar ICH (cICH) in deep (white matter, deep nuclei, cerebellar peduncle) regions. We tested the hypothesis that HA-associated neuroimaging markers are significantly associated with deep cICH compared to superficial cICH.
Patients And Methods: Brain MRI scans from consecutive non-traumatic cICH patients admitted to a referral center were analyzed for cSVD markers.

Purpose: Many patients originally transported to non-trauma centers (NTC) require transfer to a trauma center (TC) for treatment. The aim was to analyze injury characteristics and outcomes of transfer patients and investigate the secondary overtriage (SOT).
Methods: Study included 2,056 transfers to an urban level 1 TC between 01/2016 and 06/2020.

Background: The role of beta-blockers in severe, traumatic brain injury (TBI) management is debated. Severe TBI may elicit a surge of catecholamines, which has been associated with increased morbidity and mortality. We hypothesize administering propranolol, a non-selective beta-blocker, within 48 h of TBI will reduce patient mortality within 30 days of injury.

Purpose: D-dimer, a fibrinolysis indicator, may predict functional and life outcomes in traumatic brain injury (TBI) patients. We aimed to identify optimal D-dimer cutoff values for poor functional outcomes in severe TBI.
Methods: We used data from a multi-centre prospective observational cohort study that included patients with TBI with a Glasgow Coma Scale (GCS) score ≤ 8 within 48 h after injury or required neurosurgical procedures.
