Sixteen prospective cohort studies were included, focusing on participants aged 18-65 with acute mTBI, followed for a minimum of 1 month. The recovery criterion was the resolution of symptoms not attributable to pre-existing conditions. Risk of bias was assessed using the Quality in Prognostic Studies tool, with most studies rated as moderate risk, highlighting variability in methodological rigor. Symptom resolution was reported in 49.0% to 69.5% of patients at 1 month, 40.8% to 84.4% at 3 months, 38.3% to 72.2% at 6 months, and 58.1 to 68.3% at 12 months. These findings emphasize the first 6 months as a critical period for evaluating the risk of symptom chronicity. The most commonly reported prognostic factors was baseline symptom severity, including higher intensity of symptoms such as headaches, nausea, and dizziness, as well as elevated scores on validated symptom scales. Psychiatric history, such as pre-existing anxiety or depression, was also a significant predictor of prolonged symptoms. Biomarkers, including NSE and S-100B levels, and reduced blood-derived neurotrophic factors, were associated with poorer recovery at 6 months. Demographic factors, including age, gender, and education level, showed mixed results. While some studies associated female gender, older age, and lower education with poorer recovery, others found no significant correlations. These discrepancies highlight the complexity of mTBI prognosis. Overall, more than half of patients recover within 6 months, but persistent symptoms can have a profound impact on quality of life and functional status. Identifying patients at higher risk of prolonged recovery is crucial for targeted management strategies, emphasizing the importance of individualized, evidence-based care in mTBI populations.</p>","PeriodicalId":74300,"journal":{"name":"Neurotrauma reports","volume":"6 1","pages":"355-374"},"PeriodicalIF":1.8,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12281108/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144692675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to determine associations between IGF-1 levels and post-TBI symptom severity, anxiety, and depression. This retrospective observational study at an Academic Brain Injury Center included participants evaluated 3-12 months post-TBI with available IGF-1 values and complete Rivermead Post-Concussion Symptoms Questionnaire (RPQ-13), Generalized Anxiety Disorder-7 (GAD-7), and Patient Health Questionnaire-9 (PHQ-9) responses.

IGF-1 <i>Z</i>-scores were standardized for age and gender. Significant negative correlations were found between IGF-1 levels and RPQ-13, GAD-7, and PHQ-9 scores across all TBI severity groups, with lower IGF-1 <i>Z</i>-scores correlating with higher symptoms of TBI, depression, and anxiety. The Generalized Linear Models showed that the IGF-1 <i>Z-</i>score is a significant predictor for GAD-7, PHQ-9, and RPQ-13. Specifically, a one-point increase in the IGF-1 <i>Z-</i>score is associated with a 29.85% decrease in anxiety symptoms on the GAD-7, a 16.30% reduction in depression severity on the PHQ-9, and a 39.23% decrease in post-TBI symptom severity on the RPQ-13.

We aimed to evaluate the prognostic factors and treatment strategies for patients with head trauma and vital signs of shock. We included 415 consecutive patients with head trauma (Abbreviated Injury Scale [AIS] score ≥3) who were transported to our institution from January 2017 to December 2023. These patients were divided into shock and non-shock groups. Data on their background, vital signs at presentation, trunk injury status, surgical intervention, and hematological findings were examined. A retrospective analysis was conducted with the modified Rankin Scale score after 3 months as the primary outcome. The patients' mean age was 53.9 ± 24.4 years, 304 (73.3%) were male, 265 (63.9%) experienced severe trauma (injury severity score ≥16), 124 (29.9%) had multiple trauma (AIS score ≥3 at two or more locations), and 59 (14.2%) had accompanying vital signs of shock (shock index >1). Multivariable analysis revealed that older age (<i>p</i> < 0.0001), a lower Glasgow Coma Scale (GCS) score (<i>p</i> < 0.0001), elevated D-dimer levels (<i>p</i> = 0.0077), and pupillary abnormalities (<i>p</i> = 0.038) were independently associated with a poor prognosis in the non-shock group. In the shock group, older age (<i>p</i> = 0.0037) and neurosurgical intervention (<i>p</i> = 0.012) were independent prognostic factors. In contrast to those in the non-shock group, the GCS score and D-dimer levels were not useful prognostic factors in the shock group.
