Brain Injury & PTSD: Veterans' Study Suggests Area of Damage Is Key

Brain damage that veterans suffered from flying shrapnel has provided a major clue that could lead to better treatment for post-traumatic stress disorder (PTSD), a new study says.

Veterans who suffered shrapnel damage connected to their amygdala, the fear center of the brain, were less likely to develop PTSD, researchers reported Sept. 24 in the journal

  • Initial Symptoms of MS Could Guide Prognosis, Treatment

    Two key symptoms that can arise soon after a diagnosis of multiple sclerosis (MS) could predict how swiftly the illness will progress and suggest best treatment options, new research shows.

    The two symptoms -- blurred vision and sphincter dysfunction of the bladder and/or bowel -- can arise in some, but not all, patients early in the disease.

    When they do surface so quickly, patient...

    Some Diabetes Meds Could Lower Odds for Dementia, Parkinson's

    A specific class of diabetes drug appears to lower people’s risk for dementia and Parkinson’s disease, a new study shows.

    Sodium-glucose cotransporter-2 (SGLT2) inhibitors, also known as gliflozins, lower blood sugar by prompting the kidneys to filter sugar out of the bloodstream and excrete it in urine, researchers said.

    But these drugs might also protect brain health, ...

    Some People With MS May Need Earlier, Higher-Dose Meds

    Early, aggressive treatment of brain lesions caused by multiple sclerosis could help ward off faster decline in patients, a new study finds.

    Such treatment could prevent or potentially cure paramagnetic rim lesions (PRL), areas of chronic brain inflammation that are linked to more rapid deterioration in MS patients, researchers report.

    “Checking PRL levels is not currently a s...

    Wildfire Smoke Might Harm Children's Mental Health

    “The maternal brain...

    Breathing Could Bring Microplastics Into the Human Brain, Study Shows

    For the first time, scientists have detected microscopic microplastics lodged in the human brain.

    Researchers in Germany and Brazil say that 8 out of 15 autopsied adults had microplastics detected within their brain's smell centers, the olfactory bulb.

    The particles were likely breathed in over a lifetime, since tiny floating microplastics are ubiquitous in the air.

    Study Debunks Theory Linking Autism to Changes in Brain's Amygdala

    A new brain imaging study has concluded that autism likely isn’t caused by faulty connections to the amygdala.

    A prevailing hypothesis of autism spectrum disorder has held that people with the condition have poorer neural connections in certain brain regions, including the amygdala.

    However, researchers found no evidence that people with autism had amygdala connections that di...

    Depression Might Sometimes Be Early Sign of Alzheimer's Disease

    In some people, new-onset depression may stem from the same buildup of toxic plaques in the brain that have long been linked to Alzheimer's disease, according to a new study.

    Diabetes Can Age Your Brain,  But Lifestyle Change Can Reverse That

    Diabetes can age the brain by up to four years, a new study based on MRI scans shows.

    There was one silver lining: Healthy lifestyle changes could help prevent that neurological aging, the Swedish researchers said.

    “Having an older-appearing brain for one’s chronological age can indicate deviation from the normal aging process and may constitute an early warning sign for...

    Insights From a Fish Might Help People Battling Spinal Cord Injury

    A fish might hold clues to healing spinal cord injuries in humans, researchers report.

    The damaged nerve cells of zebrafish can survive a spinal cord injury, eventually restoring full movement in the fish.

    That’s very unlike humans and most other mammals, in which damaged neurons always die, researchers said.

    But the way the zebrafish neurons first survive and then heal ...
