Background/Objectives: Decompressive craniectomy (DC) is commonly applied to manage refractory intracranial hypertension in severe traumatic brain injury (TBI). However, its role and benefits in pediatric populations remain uncertain. Clarifying whether DC provides measurable clinical advantages in children with severe TBI may inform treatment strategies and family counseling. Methods: We conducted a retrospective, one-to-one matched cohort study at a tertiary pediatric center (2014–2023). Fifty-three children with severe TBI who underwent DC were matched with fifty-three non-DC patients based on age, Glasgow Coma Scale score, cranial CT findings, and pupillary response at admission to ensure comparable injury severity. Demographic data, clinical features, and outcomes were collected. Primary outcomes were in-hospital mortality and Pediatric Cerebral Performance Category (PCPC) scores at discharge and 3 months. Secondary outcomes included duration of mechanical ventilation, intensive care unit (ICU) stay, and total hospital stay. Results: Mortality did not differ significantly between DC and non-DC groups (17.0% vs. 26.4%, p = 0.239). DC patients had better PCPC scores at discharge (p = 0.029). At 3 months, the between-group difference was not statistically significant but showed a near-significant trend (p = 0.057). No significant differences were observed in duration of ventilation (p = 0.100), ICU stay (p = 0.348), or hospital stay (p = 0.678). Conclusions: DC may not reduce short-term mortality in pediatric severe TBI but appears to be associated with more favorable neurological outcomes at discharge. Larger, adequately powered studies with standardized monitoring and longer follow-up are needed to clarify the durability and scope of potential benefits in this population. Full article

Background: Traumatic Brain Injury (TBI) in children is a major cause of morbidity and mortality worldwide. Ocular manifestations are common but often overlooked, despite their potential to cause long-term visual impairment. This study aimed to evaluate the prevalence and characteristics of ocular findings in pediatric TBI patients admitted to the intensive care unit (ICU). Method: We prospectively reviewed records of pediatric patients (≤16 years) with TBI admitted to the Neurosurgery ICU at King Abdullah University Hospital (January 2022–December 2024). TBI was defined using U.S. CDC criteria and confirmed by clinical and radiological findings. Ocular manifestations were identified from ophthalmology consultations, neurosurgical notes, and bedside examinations. Demographics, injury details, and clinical outcomes were recorded. Statistical analyses included Chi-square, Fisher’s exact, and Mann–Whitney U tests, with significance set at p ≤ 0.05. Results: Thirty-eight patients (median age: 8 years; 55.3% male) were included. Ocular findings were present in 20 patients (52.6%). These patients were significantly older (median age 10 vs. 6 years, p = 0.007) and had lower admission GCS scores (11 vs. 14, p = 0.016). Male predominance was higher in the ocular group (75.0% vs. 33.3%, p = 0.030). Ocular findings were significantly associated with surgical intervention (60.0% vs. 22.2%, p = 0.025), orbital fractures (40.0% vs. 5.6%, p = 0.021), basal skull fracture signs (p = 0.036), and extraocular muscle limitation (p = 0.048). On multivariable analysis, orbital fracture remained the only independent predictor of ocular findings (aOR 2.22, 95% CI 1.17–3.57, p = 0.02). Conclusion: Over half of pediatric ICU TBI patients demonstrated ocular manifestations, closely linked to greater injury severity and craniofacial trauma. Routine, comprehensive ophthalmological evaluation should be integrated into the multidisciplinary management of severe pediatric TBI to optimize visual and functional outcomes. Full article

Background: Traumatic brain injury (TBI) is a major public health concern. Creatinine (Cr) has been well studied as a marker of renal function, specifically the development of acute kidney injury (AKI) in TBI patients. We aimed to evaluate the effect of Cr on various clinical outcomes in patients with severe TBI. Methods: We investigated the relationship between Cr levels at various time points and a range of clinical variables, using parametric and non-parametric statistical testing. Results: 1000 patients were included in our study. We found a significant association between sex and Cr level at intensive care unit (ICU) admission and ICU discharge. Cr was positively correlated with ISS at hospital admission, ICU admission, ICU discharge, and at death. Conversely, Cr was negatively correlated with GCS at hospital admission, ICU admission, ICU discharge, and at death. Larger decreases in Cr from Hospital to ICU admission were significantly correlated with increased vent days. Larger decreases in Cr from ICU admission to ICU discharge were significantly correlated with increased hospital length of stay (LOS), ICU LOS, and vent days, likely reflecting the degree of initial hypercreatinemia. For all patients, there were significant positive correlations between Cr at admission and ICU LOS, Cr at ICU admission and ICU LOS, and Cr at ICU admission and vent days. Conclusions: Our findings support existing literature that demonstrates a positive relationship between Cr levels, ICU LOS, and vent days amongst patients with severe TBI. These data suggest renal injury is predictive of TBI outcomes. Future research should investigate the role of renal therapeutic interventions in TBI recovery. Full article

Background: Glutamate transporter 1 (GLT-1) plays a vital role in maintaining glutamate homeostasis in the body. A decreased GLT-1 expression in astrocytes can heighten neuronal sensitivity to glutamate excitotoxicity after traumatic brain injury (TBI). Despite its significance, the mechanisms behind the reduced expression of GLT-1 following TBI remain poorly understood. After TBI, the endocannabinoid 2-arachidonoyl glycerol (2-AG) is elevated several times. 2-AG is known to inhibit key positive transcriptional regulators of GLT-1. This study aims to investigate the role of 2-AG in regulating GLT-1 expression and to uncover the underlying mechanisms involved. Methods: A controlled cortical impact (CCI) model was used to establish a TBI model in C57BL/6J mice. The CB1 receptor antagonist (referred to as AM281) and the monoacylglycerol lipase (MAGL) inhibitor (referred to as JZL184) were administered to investigate the role and mechanism of 2-AG in regulating GLT-1 expression following TBI. Behavioral tests were conducted to assess neurological functions, including the open field, Y-maze, and novel object recognition tests. Apoptotic cells were identified using the TUNEL assay, while Western blot analysis and immunofluorescence were employed to determine protein expression levels. Results: The expression of GLT-1 in the contused cortex and hippocampus following TBI showed an initial decrease, followed by a gradual recovery. It began to decrease within half an hour, reached its lowest level at 2 h, and then gradually increased, returning to normal levels by 7 days. The administration of AM281 alleviated neuronal death, improved cognitive function, and reversed the reduction of GLT-1 caused by TBI in vivo. Furthermore, 2-AG decreased GLT-1 expression in astrocytes through the CB1-CREB signaling pathway. Mechanistically, 2-AG activated CB1, which inhibited CREB phosphorylation in astrocytes. This decreased GLT-1 levels and ultimately increased neuronal sensitivity to glutamate excitotoxicity. Conclusions: Our research demonstrated that the upregulation of GLT-1 expression effectively mitigated neuronal apoptosis and cognitive dysfunction by inhibiting the CB1-CREB signaling pathway. This finding may offer a promising therapeutic strategy for TBI. Full article

Background: Polytrauma remains a leading cause of mortality and disability worldwide. Although trauma-related deaths have declined in recent decades, the drivers of this trend remain incompletely understood. Traumatic brain injury (TBI) is the principal cause of death and long-term disability in polytrauma, making it a critical determinant of outcomes. This study aimed to examine long-term trends in clinical characteristics, management strategies, and outcomes of polytraumatized patients with TBI (PTBI), with a particular focus on factors influencing overall and cause-specific mortality. Methods: We conducted a retrospective observational study of a prospectively maintained trauma registry over a 25-year period (1993–2018) at the Gregorio Marañón University General Hospital (Madrid, Spain). Adult patients with PTBI were included. Epidemiological, clinical, and outcome data were analyzed globally and across four time periods. Results: Among 768 patients with PTBI, mean age was 43 years (±20), and 29% were female. Most sustained closed TBIs (96%) with concomitant severe injuries to the head, chest, and extremities (median Injury Severity Score [ISS] 27; median New Injury Severity Score [NISS] 34). Emergency surgery was required in 51%, and 84% were admitted to intensive care. Over time, the incidence of polytrauma decreased, mainly reflecting fewer traffic-related injuries following advances in prevention and legislation. Despite an increasingly older and comorbid population, ISS/NISS and early mortality declined, largely due to improvements in prehospital care and hemorrhage control. Although crude TBI-related mortality appeared unchanged (28%), this pattern likely reflects offsetting influences, including an older and more comorbid patient population, a higher relative burden of severe cases, and the limitations of mortality alone to capture gains in functional outcomes. Conclusions: Advances in trauma systems and preventive policies have substantially reduced the burden of polytrauma and improved survival. However, severe TBI remains the principal unresolved challenge, highlighting the urgent need for innovative neuroprotective strategies and greater emphasis on functional recovery. Full article

Traumatic brain injury (TBI) remains a major global health problem, contributing significantly to morbidity and mortality worldwide. Despite advances in understanding its complex pathophysiology, current therapeutic strategies are insufficient in addressing the long-term cognitive, emotional, and neurological impairments. While the primary mechanical injury is immediate and unavoidable, the secondary phase involves a cascade of biological processes leading to neuroinflammation, blood–brain barrier (BBB) disruption, and systemic immune activation. The heterogeneity of patient responses underscores the urgent need for reliable biomarkers and targeted interventions. Emerging evidence highlights the gut–brain axis as a critical modulator of the secondary phase, with microbiota-derived extracellular vesicles (MEVs) representing a promising avenue for both diagnosis and therapy. MEVs can cross the intestinal barrier and BBB, carrying biomolecules that influence neuronal survival, synaptic plasticity, and inflammatory signaling. These properties make MEVs promising biomarkers for early detection, severity classification, and prognosis in TBI, while also offering therapeutic potential through modulation of neuroinflammation and promotion of neural repair. MEV-based strategies could enable tailored interventions based on the individual’s microbiome profile, immune status, and injury characteristics. The integration of multi-omics with artificial intelligence is expected to fully unlock the diagnostic and therapeutic potential of MEVs. These approaches can identify molecular subtypes, predict outcomes, and facilitate real-time clinical decision-making. By bridging microbiology, neuroscience, and precision medicine, MEVs hold transformative potential to advance TBI diagnosis, monitoring, and treatment. This review also identifies key research gaps and proposes future directions for MEVs in precision diagnostics and gut microbiota-based therapeutics in neurotrauma care. Full article

Background/Objectives: Biochemical processes such as the glycolytic pathway and Kreb’s cycle are important in producing ATP for the brain. Without a sufficient supply of glucose for energy metabolism, the brain cannot efficiently regulate or coordinate the actions and reactions of the body. It is well documented that traumatic brain injury (TBI) is associated with reduced energy metabolism through the production of reactive oxygen/nitrogen species. Antioxidants, such as glutathione (GSH), have been shown to combat the deleterious effects of oxidation by scavenging ROS/RNS, inhibiting propagation, and removing neurotoxic byproducts. Gamma-glutamylcysteine ethyl ester (GCEE), an ethyl ester moiety of gamma-glutamylcysteine, exhibits antioxidant activity by increasing GSH production. This therapeutic has protective effects against oxidative stress through the elevation of glutathione. Methods: This study investigates the enzymatic activities of several key energy-related proteins that have been identified as nitrated in treated Wistar rats with moderate TBI. To test the hypothesis that the elevation of GSH production upon administration of GCEE will normalize enzymatic activity post-TBI, adult male Wistar rats were equally divided into three groups: sham, saline, and GCEE. Rats were treated with 150 mg/kg saline or GCEE at 30 and 60 min post-TBI. Upon sacrifice, brains were harvested and enzymatic activity was measured spectrophotometrically. Results: An increase in enzymatic activity upon GSH elevation via GCEE administration in several key enzymes was observed. Conclusions: GCEE is a potential therapeutic strategy to restore energy-related proteins in the brain post-TBI via GSH elevation. Full article

Background: Post-traumatic epilepsy (PTE) is a recognized complication of traumatic brain injury (TBI), yet its risk following mild and moderate TBI remains underappreciated. Although mild TBI represents the majority of cases in clinical practice, a subset of patients develop unprovoked seizures months or even years post-injury. This review aims to synthesize current evidence on the incidence and predictors of PTE in mild and moderate TBI and to propose a clinically actionable decision-support tool for early risk stratification. Methods: We performed a narrative review of peer-reviewed studies published between 1985 and 2024 that reported on the incidence, risk factors and predictive models of PTE in patients with mild (Glasgow Coma Scale [GCS] 13–15) and moderate (GCS 9–12 or imaging-positive) TBI. Data from 24 studies were extracted, focusing on neuroimaging findings, early post-traumatic seizures, EEG abnormalities and clinical risk factors. These variables were integrated into a rule-based algorithm, which was implemented using Streamlit to enable real-time clinical decision-making. The decision-support tool incorporated five domains: injury severity, early post-traumatic seizures, neuroimaging findings (including contusion location and hematoma type), clinical and demographic variables (age, sex, psychiatric comorbidities, prior TBI, neurosurgical intervention) and EEG abnormalities. Results: PTE incidence following mild TBI ranged from <1% to 10%, with increased risk observed in patients presenting with intracranial hemorrhage or early seizures. From moderate TBI, incidence rates were consistently higher (6–12%). Key predictors included early seizures, frontal or temporal contusions, subdural hematoma, multiple contusions and midline shift. Additional risk-enhancing factors included prolonged loss of consciousness, male sex, psychiatric comorbidities and abnormal EEG patterns. Based on these features, we developed a decision-support tool that stratifies patients into low-, moderate- and high-risk categories for developing PTE. Conclusions: Even in non-severe cases, patients with mild and moderate TBI who exhibit high-risk features remain vulnerable to long-term epileptogenesis. Our proposed tool provides a pragmatic, evidence-based framework for early identification and follow-up planning. Prospective validation studies are needed to confirm its predictive accuracy and optimize its clinical utility. Full article

Introduction: Traumatic brain injury (TBI) represents one of the leading health concerns worldwide, and it is associated with high morbidity, mortality, and substantial healthcare costs. This study aimed to assess inpatient cost determinant factors among TBI patients admitted to an Eastern European hospital, Cluj County Emergency Hospital, Romania, in 2022. Methods: A retrospective observational analysis was conducted on 90 TBI patients. Data on demographic factors, clinical variables, injury characteristics, and inpatient hospital costs were collected. Inpatient total cost differences considering categorical variables were analyzed using Wilcoxon and Kruskal–Wallis tests, and correlations of inpatient total costs with other continuous variables were analyzed using Spearman correlations. Results: Most patients were male (67.8%), urban residents (67.8%), retired (64.4%), and had a mild TBI (96.7%), and the main listed cause was falls (74.4%). The average inpatient cost was EUR 1115.79. There were no statistically significant differences for costs in TBI severity, PTA, or comorbidities. Inpatient costs were correlated with hospital length of stay (ρ = 0.979, 95% CI rho: 0.969 and 986, p < 0.001). While higher costs were seen in patients with PTA, more comorbidities, severe Marshall Scores, or return-to-work status, these differences were not statistically significant. Conclusions: Further research with larger, multicenter cohorts is needed to better understand the cost structure of TBI care and to inform policy decisions that are aimed at resource allocation and cost efficiency.

Heterotopic ossification (HO) is a disease characterized by ectopic bone formation, which can occur following severe traumatic brain injury (TBI). However, the underlying mechanisms remain poorly understood. In this study, we established a stem cell model using adipose-derived stem cells (ADSCs) and skeletal stem cells (SSCs) to examine osteogenic factors present in the sera of TBI patients. Incubation of ADSCs and SSCs with osteoinductive medium supplemented with TBI serum significantly enhanced osteogenic differentiation, particularly in male ADSCs and both female and male SSCs, with male SSCs exhibiting the highest osteogenic potential. Furthermore, we identified TGF-β1 as an important factor involved in these osteogenic processes. Elevated levels of TGF-β1 were detected in the serum of male TBI patients 14 days post-injury. Cellular assays revealed a sexual dimorphism in response to TGF-β1 neutralization: osteogenic differentiation in male SSCs was significantly reduced, while no effect was detectable in female SSCs. These findings, together with the rarity of HO in female patients, suggest that TGF-β1 plays a central role in the development of HO in males. Furthermore, this study highlights the importance of considering sex-specific mechanisms in traumatic HO for the development of sex-specific therapy options. Full article

Background: Animal-assisted activities (AAA) are participative interventions, designed to lower hospitalization-related stress and anxiety, enhance communicative readiness, improve quality of life and encourage human–animal interaction. The aim of the present study was to evaluate AAA effects in the context of intensive rehabilitation of patients with spinal cord injury (SCI), traumatic brain injury (TBI), stroke. Methods: AAA in this study were structured by a local specialized association, for small groups of patients (5/7 a time), biweekly; each session lasted 60 min. Each patient participated in 10 sessions of AAA. Evaluation rating scales were administered at T0 (before the first session) and T1 (after the last session, five weeks later) as follows: Neurobehavioral Rating Scale (NRS) in case of patient with stroke/TBI without disorder of consciousness; Hospital Anxiety and Depression Scale (HADS) for SCI patients. Results: A total of 50 patients concluded the study. NRS score for joined TBI and stroke populations varied from a T0 mean value of 32.34 [C.I. 26.83–37.35] to 17.21 [C.I. 12.66–21.76] (46.7%); this difference proved to be statistically significant (p = 0.000). Stroke patients had a 57.6% NRS lowering by mean 28.10 [C.I. 20.55–35.65] points to 12 [C.I. 6.6–17.36], which was significant (p = 0.000); similarly, TBI patients showed a mean decrease of 35.8% points from the initial 41.6 points [C.I. 37.29–45.93] to 26.76 [C.I. 21.94–31.59] (p = 0.002). As for HADS scores a smaller improvement was found in the cohort of SCI patients: anxiety registered a 1 mean point decrease at T1 (21.5%), from the initial 6.5 points [C.I. 3.80–9.34] to 5.1 ones [C.I. 3.17–7.11]. This variation was near the threshold of significance (p = 0.05). Depression domain, instead, improved by 2.35 mean points (37%), from the 6.35 initial points [C.I. 3.45–9.26] to the final 4 [C.I. 2.15–5.98] with reaching of a significant p value (p = 0.03). ANCOVA did not confirm this last value and showed no influence of age and gender on outcome variations. Discussion: AAA showed preliminary evidence to decrease neurobehavioral disorders in patients with high-complexity neurological diseases, particularly stroke and TBI. The role of AAA in SCI patients remains unclear. Future studies should address confounders’ role for these populations, particularly severity of disease. Furthermore, AAA interventions will have to be studied on larger samples, deepening the exact phase to introduce AAA for neurological patients. Lastly, qualitative studies are needed to explore patients’ lived experiences. Full article

Background: Traumatic brain injury (TBI) remains a significant cause of global mortality and morbidity. This study investigated the association between initial De Ritis ratio (serum AST/ALT) and mortality in moderate-to-severe TBI patients. Methods: This retrospective study analyzed 4415 adult patients with moderate-to-severe TBI (head/neck AIS ≥ 3) from January 2009 to December 2020. Patients were categorized into three groups based on De Ritis ratios: ≤1.2 (n = 1296), 1.2 < ratio ≤ 1.64 (n = 1499), and >1.64 (n = 1620). Propensity score matching was performed to adjust for baseline characteristics including age, sex, comorbidities, Glasgow Coma Scale, and Injury Severity Score. Results: Higher De Ritis ratios were also associated with increased intensive care unit admission rates and longer hospital stays. After propensity score matching, patients with De Ritis ratio > 1.64 showed significantly higher mortality rates compared to the control group (10.3% vs. 7.9%, odds ratio (OR) = 1.33, 95% confidence interval (CI) 1.01–1.77, p = 0.046). No significant mortality difference was found between patients with De Ritis ratio ≤1.2 and the control group. Conclusions: Initial De Ritis ratio>1.64 serves as an independent predictor of mortality in moderate-to-severe TBI patients. This readily available laboratory parameter could provide valuable prognostic information for early risk stratification in TBI management. Full article

Background: The cerebral compliance (or compensatory reserve) index, RAP, is a critical yet underutilized physiological marker in the management of moderate-to-severe traumatic brain injury (TBI). While RAP offers promise as a continuous bedside metric, its broader cerebral physiological context remains partly understood. This study aims to characterize the burden of impaired RAP in relation to other key components of cerebral physiology. Methods: Archived data from 379 moderate-to-severe TBI patients were analyzed using descriptive and threshold-based methods across three RAP states (impaired, intact/transitional, and exhausted). Agglomerative hierarchical clustering, principal component analysis, and kernel-based clustering were applied to explore multivariate covariance structures. Then, high-frequency temporal analyses, including vector autoregressive integrated moving average impulse response functions (VARIMA IRF), cross-correlation, and Granger causality, were performed to assess dynamic coupling between RAP and other physiological signals. Results: Impaired and exhausted RAP states were associated with elevated intracranial pressure (p = 0.021). Regarding AMP, impaired RAP was associated with elevated levels, while exhausted RAP was associated with reduced pulse amplitude (p = 3.94 × 10−9). These two RAP states were also associated with compromised autoregulation and diminished perfusion. Clustering analyses consistently grouped RAP with its constituent signals (ICP and AMP), followed by brain oxygenation parameters (brain tissue oxygenation (PbtO2) and regional cerebral oxygen saturation (rSO2)). Cerebral autoregulation (CA) indices clustered more closely with RAP under impaired autoregulatory states. Temporal analyses revealed that RAP exhibited comparatively stronger responses to ICP and arterial blood pressure (ABP) at 1-min resolution. Moreover, when comparing ICP-derived and near-infrared spectroscopy (NIRS)-derived CA indices, they clustered more closely to RAP, and RAP demonstrated greater sensitivity to changes in these ICP-derived CA indices in high-frequency temporal analyses. These trends remained consistent at lower temporal resolutions as well. Conclusion: RAP relationships with other parameters remain consistent and differ meaningfully across compliance states. Integrating RAP into patient trajectory modelling and developing predictive frameworks based on these findings across different RAP states can map the evolution of cerebral physiology over time. This approach may improve prognostication and guide individualized interventions in TBI management. Therefore, these findings support RAP’s potential as a valuable metric for bedside monitoring and its prospective role in guiding patient trajectory modeling and interventional studies in TBI.

Background: Severe traumatic brain injury (sTBI) in adults remains a leading cause of mortality and disability worldwide. Early identification of reliable predictors of outcome is crucial for risk stratification and ICU management. Disturbances of hemostasis and metabolic factors such as body mass index (BMI) have been proposed as potential prognostic markers, but evidence remains limited. Methods: We conducted a retrospective, multicenter study including 307 adult patients with sTBI (Glasgow Coma Scale ≤ 8) admitted to three tertiary intensive care units in Ukraine between September 2023 and July 2024. All patients underwent surgical evacuation of hematomas and decompressive craniotomy. Laboratory parameters (APTT, INR, fibrinogen, platelets, D-dimer) were collected within 12 h of admission. BMI was calculated from measured height and weight. Predictive modeling was performed using L1-regularized logistic regression and Random Forest algorithms. Class imbalance was addressed with SMOTE. Model performance was assessed by AUC, accuracy, calibration, and feature importance. Results: The 28-day all-cause mortality was 32.9%. Compared with survivors, non-survivors had significantly lower GCS scores and higher INR, D-dimer, and APTT values. Very high VIF values indicated severe multicollinearity between predictors. Classical logistic regression was not estimable due to perfect separation; therefore, regularized logistic regression and Random Forest were applied. Random Forest demonstrated higher performance (AUC 0.95, accuracy ≈ 90%) than logistic regression (AUC 0.77, accuracy 70.1%), although results must be interpreted cautiously given the small sample size and potential overfitting. Feature importance analysis identified increased BMI, prolonged APTT, and elevated D-dimer as leading predictors of mortality. Sensitivity analysis excluding BMI still yielded strong performance (AUC 0.91), confirming the prognostic value of coagulation markers and GCS. Conclusions: Mortality in adult sTBI patients was strongly associated with impaired hemostasis, obesity, and low neurological status at admission. Machine learning-based modeling demonstrated promising predictive accuracy but is exploratory in nature. Findings should be interpreted with caution due to retrospective design, severe multicollinearity, potential overfitting, and absence of external validation. Larger, prospective, multicenter studies are needed to confirm these results and improve early risk stratification in severe TBI. Full article

Introduction: Mild traumatic brain injury (mTBI) in older adults (≥65 years) is often underestimated, despite being associated with significant morbidity. Age-related vulnerability, comorbidities, and medication use may exacerbate outcomes. This study aimed to identify predictors of brain health and functional recovery in older adults following mTBI, focusing on acute symptoms, CT imaging findings, and sociodemographic factors. Methods: We analyzed a cohort of 93 older adult patients with mTBI (GCS 13–15) who were prospectively enrolled at a tertiary neurosurgical center. All patients underwent baseline CT, structured clinical assessment, and follow-up at six months with standardized instruments (Glasgow Outcome Scale–Extended-GOSE, 12-Item Short Form Health Survey (quality-of-life measure)-SF-12, Rivermead Post-Concussion Symptoms Questionnaire-RPQ, Patient Health Questionnaire-9 (depression measure)-PHQ-9, PTSD (Post Traumatics Stress Disorder) Checklist for DSM (Diagnostic and Statistical Manual for Mental Disorders)-PCL-5, Timed up and Go Test (mobility measure-TUG test). Multivariate regression was performed to identify independent predictors of recovery. Results: At six months, 94.9% of older adults achieved functional independence (GOSE ≥ 5), though only 43% attained complete recovery (GOSE = 8). Patients with acute intracranial lesions on CT had worse physical outcomes, including slower mobility (mean TUG 17.6 vs. 16.3 s, p = 0.012). Severe acute headache independently predicted poorer recovery (lower GOSE and SF-12 PCS). Lower educational attainment correlated with worse functional and quality-of-life outcomes, consistent with reduced cognitive reserve. Psychological outcomes (PTSD and depression rates) were not associated with CT findings but were influenced by social support and sex. Prompt anticoagulation reversal in patients on anticoagulants markedly reduced hemorrhagic complications. Discussion: Older adults with mTBI generally maintain independence but experience reduced physical health and mobility compared to younger patients. Predictors of poorer outcomes include severe acute symptoms, CT-detected lesions, advanced age, and lower educational levels. Psychosocial support mitigated mental health complications. Conclusions: mTBI in older adults is not benign. Clinical, imaging, and sociodemographic factors collectively shape recovery. Early identification of high-risk patients and targeted interventions are essential to preserve brain health and independence in this growing population. Full article
