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.

Although ...

    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...

    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...

    Dementia May Not Be as Common Among Parkinson's Patients as Thought

    Many people with Parkinson's disease may fear dementia as a common consequence of the disease.

    But new research suggests dementia is not inevitable with Parkinson's, and in fact is less common than presumed.

    If dementia does occur, it typically does so much later in life than was previously assumed, the study also found.

    “These results provide more hopeful estimates of ...

    That's what a team at the University of Missouri-Columbia are working on in their lab....

    Scientists May Have Spotted Way to Predict Seizures

    The risk of seizures within the next 24 hours can be predicted by watching for abnormal brain activity patterns in people with epilepsy, a new study finds.

    The storm of brain activity that characterized a seizure is presaged by abnormal communication between specific areas of the brain, researchers discovered.

    They say they can forecast seizure risk by analyzing just 90 seconds of t...

    Could Contact Sports Raise Risks for a Parkinson's-like Disorder?

    Autopsies of deceased boxers and pro football players have long confirmed that repeat head injuries can lead to a devastating brain condition known as chronic traumatic encephalopathy (CTE).

    What Is a Cerebral Aneurysm? What Are the Signs?

    Cerebral aneurysms: For most people, the word signals a sudden, fatal brain bleed that seemingly comes out of nowhere.

    However, an expert at Penn State Health says that in many cases these brain blood vessel ruptures are spotted early, before they rupture. And even when they do occur, they are not uniformly fatal.

    Brain's 'Food Smell' Circuitry Might Drive Overeating

    The smell of food is appetizing when you're hungry. At the same time, it can be a turnoff if you're full.

    That's due to the interaction between two different parts of the brain involving sense of smell and behavior motivation, a new study finds.

    And it could be why some people can't easily stop eating wh...
