Daytime Drowsiness Linked to a 'Pre-Dementia' Syndrome

Seniors who are drowsy during the day and find it hard to muster enthusiasm for activities could be at higher risk of a brain condition that precedes dementia, a new study warns.

These sleep-related problems are associated with "motoric cognitive risk syndrome," a pre-demen...

Little More Learning Might Not Save Your Aging Brain

In 1972, Britain bumped up the total school years mandated for its children from 15 to 16 years.

That created a "natural experiment": Would Britons who got that extra year of education fare any better, neurologically, as they aged?

Unfortunately, the answer is "no."

"This surprised us," said study co-author and brain researcher Nicholas Judd

Mindfulness Meditation Could Have Direct Effect in Reducing Pain

Many people turn to mindfulness meditation to help them manage their chronic pain, a practice that’s been used for centuries.

However, it’s been an open question whether meditation is simply functioning as a placebo, rather than actually quelling pain.

Now, a new study involving brain scans has revealed that's not the case.

    • New Approach to Fight Huntington's Disease Shows Early Promise

    Huntington's disease is a devastating, fatal neurological illness with little means of treatment, but a new study in mice offers a glimmer of hope.

    Huntington's occurs when inherited genes cause key proteins to fold and clump together within brain cells. Over time, this severely hampers brain function and patients lose the ability to talk, walk, swallow and focus. There's no cure, a...

    Even 'Weekend Warrior' Exercise Can Keep Your Brain Healthy

    Find it hard to take time to exercise during your busy workweek?

    No problem, a new study says -- one or two “weekend warrior” workouts are just as likely to help you maintain your brain health.

    People who regularly exercise, whether solely on the weekend or thro...

    Can Cannabis Change Your Brain? Maybe, Maybe Not

    People who regularly use marijuana experience changes in their brain structure and function, but it’s not clear that cannabis is the cause, a new study finds.

    Researchers found specific differences in the brains of people who’d ever used weed, particularly in areas densely packed with cannabinoid receptors. However, genetic analysis couldn’t pin down any specific associa...

    Childhood Attention Issues Show Links to Later Risk for Psychosis, Schizophrenia

    Most kids with attention issues won't go on to develop serious psychiatric conditions like psychosis or schizophrenia.

    However, a new study finds poor attention spans in childhood, plus certain genes, could play a role in raising the risk for these conditions.

    Of course, much more research is needed to pinpoint precursors to psychotic symptoms in a person's teens or 20s, said a t...

    Weed Use During Pregnancy May Harm Kids' Behavior, Thinking Skills

    Smoking marijuana during pregnancy may quell your morning sickness, but it could also harm your child’s development, a new study warns.

    Cannabis exposure in the womb is associated in early childhood with poorer thinking skills, researchers reported Oct. 28 in the journal JAMA Pediatrics.

    These kids also have behavioral problems like impulse control, poor attention an...

    People's Brains Now Process Texts Almost as Quickly as Pictures

    Texts deliver rapid-fire messages, but a new study indicates human brains can keep up with the barrage.

    The brain can detect the basic linguistic structure of a brief sentence in roughly 150 milliseconds -- about the speed of a blink of an eye, researchers report.

    “Our experiments reveal that the brain’s language comprehension system may be able to perceive language simi...

    What Works Best to Ease MS-Linked Fatigue? New Study Finds Out

    Medication and behavioral therapy are both effective in combatting fatigue caused by multiple sclerosis (MS), either separately or together, a new study finds.

    Bad Sleep in Middle Age Unhealthy for Aging Brains

    If you're in your 40s or 50s and have trouble getting and staying asleep, that's not a good sign for brain health as you age, new research suggests.

    Your Sense of Smell May Be Quicker Than You Think

    People sense millisecond shifts in odor as quickly as they might spot a change in color, new research shows.

    The study discounts the notion that smell is a "slower" sense than sight or hearing, scientists say.

    "A sniff of odors is not a long exposure shot of the chemical environment that averages out" over time, explained study lead author

    Injected 'Nanodiscs' Could Bring Brain Stimulation Therapy Without Implants

    Microscopic magnetic nanodiscs could provide a much less invasive means of providing deep brain stimulation, a new study says.

    The tiny discs – about 250 nanometers across, or 1/500 the width of a human hair – would be injected directly into specific regions of a person’s brain, researchers say.

    From there, researchers said, the discs could be activated by applying...

    Boys Treated With Gene Therapy for Rare Brain Disease Doing Well 6 Years Later

    Most boys treated with breakthrough gene therapy for a rare but deadly brain illness are faring well six years later, two new reports find.

    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.
