Brain Lesions Heighten Impulsivity and Social Influence

New research shows that damage to specific regions of the medial prefrontal cortex (mPFC) increases both impulsivity and susceptibility to the impulsive behavior of others. Participants with mPFC lesions were more likely to choose immediate rewards and to be influenced by others who made impulsive decisions.

Police at Greater Risk of Brain Trauma and PTSD

A large new study reveals police officers are more than twice as likely to sustain traumatic brain injuries (TBIs) as the general population, with those injured on duty facing double the risk of developing complex PTSD. The research, which surveyed over 600 UK frontline officers, found that 38% had experienced at least one TBI, often accompanied by symptoms like confusion or memory loss.

Sleep Brain Waves Linked to Consciousness in Coma

A new study finds that sleep spindles—bursts of brain activity during sleep—may predict recovery in unresponsive patients with recent brain injuries. Researchers analyzed EEG recordings of 226 comatose patients and found that those with sleep spindles were significantly more likely to regain consciousness and functional independence.

Men Are Three Times As Likely to Die From Brain Injuries

A 2021 analysis of U.S. mortality data highlights disparities in traumatic brain injury (TBI)-related deaths, which disproportionately affect older adults, men, and certain racial and ethnic groups. Suicides remain the leading cause, followed by unintentional falls, with older adults (75+) and American Indian/Alaska Native individuals experiencing the highest mortality rates.

Head Trauma May Reactivate Dormant Viruses, Increasing Alzheimer’s Risk

New research suggests that concussions and repetitive head trauma may reactivate dormant viruses like HSV-1 in the brain, potentially triggering neurodegenerative diseases such as Alzheimer’s. Using a brain tissue model, scientists observed that head trauma caused latent HSV-1 to awaken, leading to hallmark Alzheimer’s markers such as amyloid plaques, inflammation, and neuronal damage.

Disrupted Protein Clearance After TBI Tied to Alzheimer’s

A study has found that traumatic brain injury (TBI) increases the risk of Alzheimer’s disease by disrupting protein clearance, leading to the accumulation of toxic tau proteins in the brain. Researchers discovered that TBI downregulates BAG3, a protein crucial for clearing damaged proteins, which contributes to Alzheimer's-related tau buildup.

Infrared Light Therapy Shows Promise for Brain Injury Recovery

Scientists have found that transcranial infrared light therapy may promote tissue repair after mild traumatic brain injury (mTBI). In animal studies, brief daily infrared treatments reduced harmful inflammatory activity and cell death in the brain post-injury.

Blood Tests Uncover Lasting Damage Following Single Brain Injury

A new study reveals that moderate-to-severe traumatic brain injuries (TBI) can have long-lasting effects, persisting for decades. Using advanced MRI scans, blood biomarkers, and cognitive tests, researchers found that survivors show signs of chronic brain pathology even 22 years after their injury.

Higher TBI Risk Found in Wealthier, Healthier Seniors

13% of older adults are diagnosed with traumatic brain injury (TBI), often from ground-level falls. The study found that wealthier, healthier, and more active seniors have a higher risk of TBI, contrary to previous findings in younger populations. This research highlights the need for tailored post-TBI care and preventative measures.

Memory Loss from TBI Reversed

Researchers made a breakthrough in understanding memory loss due to repeated head impacts, as often experienced by athletes. Their study reveals that memory issues following head injury in mice are linked to inadequate reactivation of neurons involved in memory formation.

Implant Shows Promise in Restoring Cognitive Function After Brain Injury

A groundbreaking study successfully restored cognitive function in patients with lasting impairments from traumatic brain injuries using deep-brain-stimulation devices. This innovative technique targets the central lateral nucleus in the thalamus to reactivate neural pathways associated with attention and arousal.
