Acute cognitive postconcussive symptoms follow longer recovery trajectories than somatic postconcussive symptoms in young children.
Objective: To investigate somatic and cognitive postconcussive symptoms (PCS) using the symptom evaluation subtest (cSCAT3-SE) of the Child Sports Concussion Assessment Tool 3 (Child SCAT) in tracking PCS up to 2 weeks postinjury. Methods: A total of 96 participants aged 5 to 12 years (Mage = 9.55, SD = 2.20) completed three assessment time points: 48 h postinjury (T0), 2 to 4 days postinjury (T1), and 2 weeks postinjury (T2). ⋯ Discussion: Differences between cognitive and somatic PCS emerge as early as a few days postinjury, with cognitive PCS being more persistent than somatic PCS across 2 weeks. Research in symptom-specific interventions may be of benefit in helping young children manage severe PCS as early as 2 weeks postinjury.

The Rivermead Post-Concussion Questionnaire score is associated with disability and self-reported recovery six months after mild traumatic brain injury in older adults.
Background/Objectives: Post-concussion syndrome refers to the adverse group of symptoms following a mild traumatic brain injury (mTBI). The Rivermead post-concussion syndrome questionnaire (RPQ) is a common clinical tool for assessing baseline post-concussion syndrome symptomology; however, it is unknown if scores on this questionnaire are associated with future disability. Therefore, the goal of this study was to determine the association between baseline RPQ scores and future disability in older adults with mTBI. ⋯ Individuals with higher levels of baseline symptomatology were more likely to have poor GOSE scores (RR = 2.13, 95% CI [1.51, 2.31]) and self-reported recovery (RR = 2.64, 95% CI [1.31, 8.98]) 6 months later. Conclusions: High levels of baseline symptomatology may be associated with overall disability and individual perceptions of recovery 6 months post-MTBI. While the RPQ is valid in assessing a patient's post-concussive symptoms following mTBI, it may not predict long-term physical or mental health in older adults.

Complicated mild traumatic brain injury in older adults: Post-concussion symptoms and functional outcome at one week post injury.
Primary Objective: Mild Traumatic Brain Injury (MTBI) is commonly categorized as complicated when injury severity criteria are mild, but an intracranial abnormality is present on acute neuroimaging. The current study examined whether functional outcomes differed at one week post injury among older adult patients based on injury severity and acute computed tomography (CT) findings. Research Design: Participants (≥55 years-old; n = 173) presenting sequentially to the emergency department with a head injury were divided into three groups: complicated MTBI (positive CT; n = 22), uncomplicated MTBI (negative CT; n = 68), and mild head injury (unperformed CT, no documented loss of consciousness or post-traumatic amnesia; n = 83). ⋯ Main Outcomes and Results: Participants differed on the ∆MRS and GOS-E, but not the RPQ. The complicated MTBI group had worse GOS-E ratings than the uncomplicated MTBI and mild head injury groups and worse ∆MRS than the mild head injury group, but the uncomplicated MTBI and mild head injury groups did not differ on either outcome. Conclusions: Macrostructural abnormality on CT was associated with worse functional outcome at one week post MTBI.

NFL blood levels are moderated by subconcussive impacts in a cohort of college football players.
Repetitive subconcussive head impacts in contact/collision sports such as in US football are believed to contribute to long-term brain changes and chronic symptoms. However, the lack of tools to measure the effects of repeated subconcussion limits our understanding of potential contributions to neuropathological alterations including cellular damage. ⋯ Acute changes in NFL may be a clinically useful peripheral marker in tracking acute brain damage in collegiate football players, and other contact sports.

Assessing aggression following Acquired Brain Injury (ABI): a systematic review of assessment measures.
Objective: To conduct a systematic review to identify and examine the reliability and validity of standardized measures used to assess aggression in people with ABI. Data sources: Systematic searches of PsychInfo, Medline, Embase, PubMed and CINAHL databases along with hand searching of gray literature and review articles. Study selection: Studies were included if the sample had an ABI, and the measure included assessment of aggression. ⋯ Four measures (MBPC-1990R, NFI, SASNOS and KSMS) demonstrated positive evidence of at least one psychometric property with good quality evidence. Conclusions: Although a large number of general measures were available, there are few measures that only assess post-ABI aggression, and many are not well-validated. Future research should assess the psychometric properties of these measures.
