Scientists discover that resetting the gut microbiome after a brain injury can "unscramble" signals to the brain and speed up cell repair.]]> https://neurosciencenews.com/microbiome-tbi-brain-neuroinflammation-30201/feed/ 0 115014 https://neurosciencenews.com/caqk-peptide-neurology-tbi-29785/ Tue, 07 Oct 2025 18:06:39 +0000 https://neurosciencenews.com/?p=113257 A small peptide called CAQK, composed of just four amino acids, has shown remarkable neuroprotective effects in mouse and pig models of traumatic brain injury. When injected intravenously, CAQK travels directly to damaged brain tissue, where it binds to overexpressed proteins and reduces inflammation, cell death, and tissue damage. ]]> 113257 https://neurosciencenews.com/tbi-dementia-aging-29773/ Mon, 06 Oct 2025 14:30:11 +0000 https://neurosciencenews.com/?p=113213 A large-scale Canadian study has found that older adults who sustain traumatic brain injuries (TBI) face a significantly higher risk of developing dementia, needing home care, or being admitted to long-term care. Researchers found that TBIs, most commonly caused by falls, increase dementia risk by up to 69% in the first five years following injury. ]]> 113213 https://neurosciencenews.com/tbi-brain-cancer-29611/ Mon, 25 Aug 2025 19:04:33 +0000 https://neurosciencenews.com/?p=112419 A large study of more than 75,000 people has found that moderate-to-severe traumatic brain injury (TBI) is linked to an increased risk of malignant brain tumors. Within 3–5 years of injury, 0.6% of patients with significant TBIs developed tumors—higher than those without TBI.]]> 112419 https://neurosciencenews.com/tbi-mpfc-impulsivity-28775/ Tue, 29 Apr 2025 19:08:38 +0000 https://neurosciencenews.com/?p=109333 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. ]]> 109333 https://neurosciencenews.com/police-tbi-cptsd-28630/ Mon, 14 Apr 2025 13:30:33 +0000 https://neurosciencenews.com/?p=108717 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. ]]> 108717 https://neurosciencenews.com/consciousness-sleep-spindles-28453/ https://neurosciencenews.com/consciousness-sleep-spindles-28453/#comments Mon, 03 Mar 2025 22:00:16 +0000 https://neurosciencenews.com/?p=108016 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. ]]> https://neurosciencenews.com/consciousness-sleep-spindles-28453/feed/ 1 108016 https://neurosciencenews.com/tbi-male-mortality-neurology-28347/ Fri, 10 Jan 2025 19:37:20 +0000 https://neurosciencenews.com/?p=107496 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. ]]> 107496 https://neurosciencenews.com/concussion-viruses-alzheimers-28324/ Tue, 07 Jan 2025 20:40:33 +0000 https://neurosciencenews.com/?p=107389 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. ]]> 107389 https://neurosciencenews.com/tbi-genetics-alzheimers-27883/ Fri, 18 Oct 2024 14:42:43 +0000 https://neurosciencenews.com/?p=105505 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. ]]> 105505
