Abstract

This pilot study explores the metabolic changes associated with persistent postconcussion syndrome (PCS) after mild traumatic brain injury (mTBI; >12 months after injury) using magnetic resonance spectroscopy. We hypothesized that those mTBI participants with PCS will have larger metabolic differences than those without. Data were collected from mTBI participants with PCS, mTBI participants without PCS and non-head-injured participants (all groups: n=8). Magnetic resonance spectroscopy metabolite profiles within the dorsolateral prefrontal cortex showed a reduced creatine/choline ratio in mTBI patients compared with control participants. This data provides initial evidence for residual metabolic changes in chronic mTBI patients, but there was no conclusive relationship between these metabolic changes and PCS symptom report. Creatine is involved in maintaining energy levels in cells with high or fluctuating energy demand, suggesting that there may be some residual energy impairment in chronic mTBI.

Relationship between psychosocial and psychiatric risk factors and poor long-term outcome following mild traumatic brain injury: A systematic review

Martijn de Neeling, Dirk Liessens, Bart Depreitere

Summary: Mild traumatic brain injury (mTBI) has a high incidence worldwide, and long-term persistent postconcussion symptoms (PPCS) are predicted by psychological and psychiatric factors. Anxiety, depressive symptoms, and emotional distress early after injury can predict PPCS burden and functional outcome. Coping styles, preinjury psychiatric disorders and mental health also correlate with PPCS burden and functional outcome.

S100B, Actor and Biomarker of Mild Traumatic Brain Injury

Charlotte Oris, Samy Kahouadji, Julie Durif, Damien Bouvier, Vincent Sapin

Summary: Mild traumatic brain injury (mTBI) is a growing burden worldwide, accounting for approximately 80% of all TBI cases. In recent years, candidate biomarkers have been investigated to improve the management of mTBI patients. Blood biomarker measurement in the acute phase after a traumatic event helps reduce unnecessary CT scans and hospitalizations. S100B protein has emerged as the most widely studied and used biomarker for clinical decision making in patients with mTBI. Besides its diagnostic use, S100B plays a role in the molecular pathogenic processes accompanying acute brain injury, making it a potential therapeutic target.

Summary: Major depressive disorder is associated with increased risk of brain atrophy, aging-related diseases, and mortality. This study found that MDD patients showed a higher brain-predicted age difference compared to controls, but this difference did not seem to be driven by specific clinical characteristics. Subtle patterns of age-related structural brain abnormalities in MDD were observed, highlighting the need for further longitudinal studies to assess the clinical value of these findings.

BDNF rs6265 differentially influences neurometabolites in the anterior cingulate of healthy and bipolar disorder subjects

Estevao Scotti-Muzzi, Thais Chile, Homero Vallada, Maria Concepcion Garcia Otaduy, Marcio Gerhardt Soeiro-de-Souza

Summary: Brain-derived neurotrophic factor (BDNF) is critical for neuronal growth and survival, and its polymorphism (BDNF rs6265) has been associated with changes in brain metabolites. This study investigated the influence of BDNF rs6265 on neurochemical profile in the anterior cingulate cortex (ACC) of bipolar disorder (BD) patients and healthy controls (HC). The results showed that the BDNF rs6265 polymorphism had an interaction with diagnosis and sex, affecting the levels of NAA/Cr and total Cr in the ACC. These findings suggest that BDNF rs6265 has a complex effect on ACC metabolites in BD patients, particularly in male individuals.

Summary: This study investigated the possible synergistic effects of Roux-en-Y Gastric Bypass (RYGB) and exercise training on brain functional networks. The results showed that exercise superimposed on bariatric surgery (RYGB + ET) increased connectivity between the hypothalamus and sensorial regions, and decreased connectivity in the default mode network and posterior salience network when compared to RYGB alone. This suggests that exercise training plays an important role in the management of post-bariatric patients and improves hypothalamic connectivity and brain functional networks involved in controlling food intake.
