🔬 Practice-Changing Findings
Evidence from RCTs and meta-analyses published in the
last 12 months.
|
Sports health (2026) - Network Meta-Analysis
Key Findings
- Across 20 RCTs involving 1,320 participants, multidisciplinary interventions produced the greatest symptom improvements (SMD = -2.06; P = 0.002).
- Multidisciplinary care produced the largest improvements in participants younger than 30 years (SMD = -2.42) and those with persistent symptoms (SMD = -2.999); combined vestibular rehabilitation plus subthreshold aerobic exercise and vestibular rehabilitation alone ranked next.
📋 Practice Implication: For sport-related concussion with persistent symptoms, consider coordinated multidisciplinary rehabilitation, with vestibular and subthreshold aerobic components when clinically appropriate.

Annals of family medicine (2025) - Practice Guideline
Key Findings
- The resulting guideline is designed to improve consistency across 11 outpatient priority topics for community-dwelling adults with TBI after discharge or without acute hospitalization.
- The recommendations target improved care across diagnostic confirmation, emergency evaluation, indicated imaging and neuropsychological assessment, social determinants, return to usual activities, education, persistent-symptom risk, headache, mental health, and specialty referral.
📋 Practice Implication: Use the 11-domain framework to structure outpatient TBI follow-up and reduce omissions in assessment, education, symptom treatment, and referral decisions.

International journal of molecular sciences (2026) - Meta-Analysis
Key Findings
- Across 29 clinical studies, increased neurofilament light chain, ubiquitin C-terminal hydrolase L1, total tau, and GFAP levels were consistently associated with cognitive impairment and brain atrophy across TBI severities and stages.
- Acute-phase brain-derived neurotrophic factor, neuron-specific enolase, and interleukin-1β correlated with cognitive impairment, while increased GFAP and NfL levels during recovery were associated with TBI-related cognitive impairment.
📋 Practice Implication: Biomarker interpretation should be time-specific; NfL and GFAP may help refine prognostic follow-up, but they should complement rather than replace clinical and imaging assessment until longitudinal validation improves.

Brain impairment : a multidisciplinary journal of the Australian Society for the Study of Brain Impairment (2026) - Meta-Analysis
Key Findings
- In 12 RCTs, CBT significantly improved sleep quality (PSQI MD = -3.44), insomnia severity at 6-8 weeks (MD = -2.23) and 12-16 weeks (MD = -0.91), and daytime sleepiness at 16 weeks (ESS MD = -1.45).
- Only the PSQI improvement reached the minimally clinically important difference; evidence for hyperbaric oxygen, blue-wavelength light therapy, and rTMS was very low and inconclusive, and hyperbaric oxygen had an increased risk of mild ear barotrauma versus sham (RR = 2.66).
📋 Practice Implication: Offer CBT or CBT-I as the best-supported non-drug option for post-TBI sleep disturbance, while treating other modalities as investigational and discussing hyperbaric oxygen’s ear-barotrauma risk.

Epilepsy research (2026) - Meta-Analysis
Key Findings
- Across 120 observational studies, all four acquired brain-injury categories were significantly associated with increased later epilepsy risk.
- TBI had an odds ratio of 2.28 (95% CI 2.14-2.43), while ischemic brain injury had the strongest overall association (OR 2.40; 95% CI 2.17-2.65); hemorrhagic and immune-related injuries were also associated with increased risk.
📋 Practice Implication: A history of TBI should prompt explicit counseling about delayed seizures and individualized neurologic surveillance, particularly when additional injury-related risk factors are present.

💡
Summary
Recent high-significance evidence emphasizes structured outpatient follow-up after traumatic brain injury, multidisciplinary rehabilitation for sport-related concussion, and time-specific biomarker interpretation for cognitive impairment. It also supports cognitive behavioral therapy for post-TBI sleep disturbance and ongoing surveillance for delayed epilepsy after acquired brain injury.
