TL;DR: A 2025 medRxiv fMRI preprint linked higher apathy in both traumatic brain injury (TBI) and control groups to greater effort discounting, while TBI-related apathy was also associated with less exploratory decision-making and weaker neural encoding of differences between expected and received rewards. Key Findings 53-person fMRI sample: Researchers analyzed 34 people with chronic TBI …
TL;DR: A 2026 mouse study in Blood found that Thrombosomes, a freeze-dried platelet-derived blood product, reduced bleeding, vessel leak, inflammation, and blood-brain-barrier disruption after traumatic brain injury. Key Findings Thrombosomes were tested after traumatic brain injury: the product is made from preserved platelet material and was originally designed for hemorrhage control. Treatment was given after …
Lithium shows promise in treating traumatic brain injury (TBI) by mitigating neuroinflammation, protecting against neuronal damage, and improving cognitive functions. Highlights: Neuroprotective Mechanisms: Lithium’s therapeutic effects involve complex molecular mechanisms including gene expression, neurotransmitter signaling, and circadian modulation, contributing to neuronal protection and recovery post-TBI. Targeted Brain Regions: Post-treatment, lithium concentrations are notably higher in …
Traumatic brain injury (TBI) has been called the “signature injury” of recent conflicts in Iraq and Afghanistan. TBIs are concerning because they can cause long-term issues like headaches, memory problems, and trouble thinking clearly. A new study looked at which military jobs put service members most at risk for TBIs. It found that certain combat-related …
