Article Abstract
Background: Moderate-to-severe traumatic brain injury (TBI) follows a chronic neuro-psychological sequelae, interfering with quality of life (QOL).
Objective: To investigate the chronic effects of moderate-to-severe TBI as expressed by greater atrophy in specific regions-of-interest relating to executive functions (EF) and self-awareness (SA); and whether this atrophy reflects on EF, SA deficits and QOL.
Methods: Thirty-one males with chronic moderate-to-severe TBI, aged 18-51, were compared to 24 non-injured males (age range = 21-49), matched on age and education. EF was assessed through a composite score. SA and QOL were assessed using generic and TBI-specific measures. Online masks were applied on magnetic resonance images to extract EF and SA - related regions-of-interest.
Results: Findings revealed that participants with TBI presented with less volume in fronto-temporal cortical and subcortical regions, than controls. An interrelation between EF and SA - related regions was revealed. Participants with TBI scored lower on neuropsychosocial measures, than controls. Differences in EF and SA were reflected on the related regions-of-interest. Satisfaction with QOL was predicted by these regions-of-interest.
Conclusion: Chronic TBI effects on brain volume extend on EF, SA, and QOL; highlighting the role of SA between EF and QOL, and the need for personalized interventions in improving recovery outcome.

Introduction: India experiences the highest number of road traffic fatalities globally. Acquired hypopituitarism is a common sequela in patients who sustain traumatic brain injury (TBI). This study aimed to investigate the prevalence and imaging characteristics of hypopituitarism in patients with TBI at a tertiary care centre in North India.

Background And Objectives: Moderate-to-severe traumatic brain injury (TBI) can result in disability across physical, social, and cognitive domains. The Glasgow Outcome Scale-Extended (GOSE), which evaluates global function, is the most frequently used TBI outcome measure. However, the GOSE may not capture all domains of recovery.

Objective: This post hoc study of the Progesterone for Traumatic Brain Injury, Experimental Clinical Treatment (ProTECT) III trial investigates whether improving traumatic brain injury (TBI) classification, using serum biomarkers (glial fibrillary acidic protein [GFAP] and ubiquitin carboxyl-terminal esterase L1 [UCH-L1]) and algorithmically assessed total lesion volume, could identify a subset of responders to progesterone treatment, beyond broad measures like the Glasgow Coma Scale (GCS) and Glasgow Outcome Scale-Extended (GOS-E), which may fail to capture subtle changes in TBI recovery.
Design: Brain lesion volumes on CT scans were quantified using Brain Lesion Analysis and Segmentation Tool for CT. Patients were classified into true-positive and true-negative groups based on an optimization scheme to determine a threshold that maximizes agreement between radiological assessment and objectively measured lesion volume.

Objectives: To summarize patient perspectives after participating in a behavioral intervention designed to improve adherence to positive airway pressure therapy in Veterans with traumatic brain injury (TBI) and obstructive sleep apnea. The four-module adherence intervention was based on Motivational Interviewing and Cognitive Behavior Therapy principles and was adapted for persons with cognitive impairments.
Methods: Post-intervention semi-structured interviews were conducted with 13 patients with moderate-to-severe TBI.

Background And Objectives: This retrospective study used data from the National Alzheimer's Coordinating Center (NACC) database and compared neuropathologic, neuropsychiatric, motor, and neuropsychological features between those with and without chronic traumatic encephalopathy neuropathologic change (CTE-NC).
Methods: Data were obtained from the NACC database from 2014 to December 2024, with the only inclusion criterion being evaluation for CTE-NC. Participants with CTE-NC were identified and matched approximately 1:4 to those without CTE-NC on demographics (age, education, sex) and staging of Alzheimer and Lewy body neuropathology.
