Primary Objective: Headache, both before and after injury, has been associated with worse outcome following mild traumatic brain injury (MTBI). This study examined whether three MTBI patient groups - no headache (reported no pre-/post-injury headache), pre-injury headache (reported pre-injury headache, nearly all of whom also reported post-injury headache), and post-traumatic headache only (denied pre-injury headache and reported post-injury headache) - differed in acute-to-subacute outcomes.
Research Design: Cross-sectional observational study.
Methods And Procedures: Patients within 21 days of a MTBI ( = 291) completed neuropsychological tests and questionnaires evaluating depression, anxiety, and post-concussion symptoms.
Main Outcomes And Results: Neuropsychological test performances did not differ between headache groups. Participants with pre-injury headache and participants with post-traumatic headache only reported greater change in self-reported physical and cognitive symptoms than participants with no headache. Participants with pre-injury headache reported worse post-injury anxiety symptoms than participants with post-traumatic headache only.
Conclusions: The pre-injury headache and post-traumatic headache only groups did not meaningfully differ in outcome within 21 days of MTBI, but they had worse physical and cognitive symptoms than participants with no headache. Future research should assess whether differences in outcome emerge further from injury and whether specific headache subtypes are differentially associated with outcome.

Longitudinal neurocognitive trajectories and risk factors in the first three months following pediatric concussion.
Brain Inj

Clinical Sciences, Murdoch Children's Research Institute, Melbourne, Australia.
Article Synopsis
- The study aimed to understand different recovery patterns in neurocognitive function after pediatric concussions over three months and identify factors that influence recovery trajectories.
- Researchers analyzed data from 74 kids aged 8-17 and found three distinct recovery groups: two groups showed improvement in information processing, while one group had minimal change and lower scores on cognitive tests.
- The findings highlighted that a previous history of headaches was linked to the group with the least improvement, suggesting that pre-existing conditions could help identify children who may need more support after a concussion.

Concussion evaluations use a multidimensional assessment to evaluate unique patient function dimensions (e.g., subjective symptoms differ from balance assessments), but the overarching latent factor structure has not been empirically substantiated.

Article Synopsis
- The study examined the characteristics and recovery of 473 adults with acute concussions, tracking their progress over 16 weeks post-injury.
- Falls were the leading cause of concussions for females, while males were more likely to be injured during sports or violent incidents.
- Female participants experienced more severe symptoms and longer recovery times compared to males, although a pre-existing history of depression or anxiety did not directly correlate with symptom duration.

Article Synopsis
- The study aims to analyze health care use after pediatric concussions, focusing on types, duration, intensity, and risk factors for increased visits.
- Researchers conducted a retrospective cohort study of children aged 5 to 17 diagnosed with concussions, examining health care visits before and after the injury using various statistical methods.
- Results showed that health care visits spiked in the first 28 days post-concussion, with certain pre-existing conditions like headaches and anxiety predicting prolonged and intense healthcare utilization.
