Why do some people with amyloid plaques in their brains associated with Alzheimer’s disease show no signs of the disease, while others with the same amount of plaque have clear memory and thinking problems? Researchers looked at genetic and life course factors that may help create a “cognitive reserve” that provides a buffer against the disease in a study published in the August 3, 2022, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Preeclampsia is a serious complication of pregnancy characterized by high blood pressure and kidney damage. Mayo Clinic researchers found that women with a history of severe preeclampsia have more markers linked to brain cell damage and inflammation, compared to women who had uncomplicated pregnancies.
In 1665, the Dutch scientist Christiaan Huygens hanged two of his recently invented pendulum clocks on a wooden beam and observed that as time passed, the clocks aligned their beats. Three and a half centuries later, neurons in the brain were found to sync their activities in a similar way.
According to the researchers, improving the perceptual capabilities of people with autism is a difficult challenge, requiring long and tedious training along with the difficulty that characterizes autism to generalize learning to other areas.
Beta-amyloid is far from the only factor in dementia, memory loss and Alzheimer's disease, and far from the only target for drugs, says the director of a top Alzheimer's center. Research on many molecules, and an emphasis on preventing or slowing the disease, are both crucial.
Elementary school-age children who get less than nine hours of sleep per night have significant differences in certain brain regions responsible for memory, intelligence and well-being compared to those who get the recommended nine to 12 hours of sleep per night, according to a new study led by University of Maryland School of Medicine (UMSOM) researchers.
If you compare the brain of someone who has died from neurodegenerative disease to that of a healthy person, you can’t miss the difference: In the case of severe Alzheimer’s, the brain will be noticeably smaller, with large gaps where pieces would normally nestle close together.
RUSH researchers found that a bioactive compound found in strawberries called pelargonidin may be associated with less neurofibrillary tau tangles in the brain.
How does the brain keep in mind a phone number before dialling? Working memory is an essential component of cognition, allowing the brain to remember information temporarily and use it to guide future behaviour.

Studies have shown that physical and mental activity help preserve thinking skills and delay dementia. A new study suggests that these benefits may vary for men and women. The study is published in the July 20, 2022, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Background: Although the efficacy of high-dose speech-language therapy (SLT) for individuals with poststroke aphasia has been established in the literature, there is a gap in translating these research findings to clinical practice. ...
Psychologists and biologists around Christina Krumpholz and Helmut Leder from the University of Vienna investigated whether voice pitch can influence how female faces are evaluated. Their conclusion: a higher voice does indeed influence how the corresponding face is evaluated. However, this does not apply to all ratings. Faces with a higher voice were rated as younger, but other assumptions that the faces are also rated as more attractive, more feminine or healthier do not apply. The study was published in the journal Frontiers in Psychology.
Researchers found significant differences in movement patterns between participants with normal cognition and those with mild cognitive impairment or Alzheimer’s disease.
Air pollution remains a silent killer in Massachusetts, responsible for an estimated 2,780 deaths a year and for measurable cognitive loss in Bay State children exposed to fine particulate pollutants in the air they breathe, according to a new study by researchers at Boston College’s Global Observatory on Planetary Health.
UC San Diego researchers tracked the evolution of a gene variant that supports cognitive health in older humans, but may have first emerged to protect against bacteria.

For tasks ranging from solving word puzzles to throwing darts, better performers don't necessarily give better advice—they just give more of it, finds research recently published in the journal Psychological Science.
There are certain skills that once we acquire them, we rarely have to relearn them, like riding a bike or looking both ways before crossing a street.
While thinking an unwanted thought could make it more likely to recur, we can proactively control this process
Consumption of seven or more units of alcohol per week is associated with higher iron levels in the brain, according to a study of almost 21,000 people publishing July 14th in the open access journal PLOS Medicine. Iron accumulation in the brain has been linked with Alzheimer’s and Parkinson’s diseases and is a potential mechanism for alcohol-related cognitive decline.
Children who were born preterm are at heightened risk of lower academic achievement in math, reading and other skills and are also at greater risk for attention-deficit/hyperactivity disorder (ADHD).
Researchers are one step closer to understanding the ‘internal GPS’ of animals and humans, by investigating whether rats can learn spaces just by observation.
Michael Nolting, a business major at UNC who just finished his freshman year, is sharing his dream with the world — and it’s no ordinary dream. It’s one that came to him more than four years ago in a deep sleep, involving an apocalyptic alien invasion that he never quite got out of his mind.
Finding could open new front in fight against disinformation
Our visual perception of the world is often thought of as relatively stable. However, like all of our cognitive functions, visual processing is shaped by our experiences.
Prosopagnosia, an ailment that made headlines this week after actor Brad Pitt announced that he is suffering from the disorder, is an uncommon brain malady that causes the inability to recognize faces.
A discovery about how algorithms can learn and retain information more efficiently offers potential insight into the brain’s ability to absorb new knowledge. The findings by researchers at the University of California, Irvine School of Biological Sciences could aid in combatting cognitive impairments and improving technology.
New study on our connection to our voice contributes to better understanding of auditory hallucinations and could improve VR experiences.
A new study from Cornell University shows babies learn that their prelinguistic vocalizations – coos, grunts and vowel sounds – change the behaviors of other people, a key building block of communication.
The findings challenge the theory that perceptions of children are simply a noisier version of adult understanding, and suggest instead that children have their own unique way of understanding and interpreting the world.
Researchers at Montefiore Medical Center found that about 30% of ICU survivors could not complete a simple screening assessment for cognitive impairment at hospital discharge. About 47% of those who were able to complete the assessment scored at a level consistent with severe cognitive impairment.

Irvine, Calif., June 21, 2022 — If you are skilled at playing puzzles on your smartphone or tablet, what does it say about how fast you learn new puzzles, or more broadly, how well can you focus in school or at work? In the language of psychologists, does “near transfer” predict “far transfer”? A team of psychologists from the University of California, Irvine and the University of California, Riverside reports in Nature Human Behavior that people who show near transfer are more likely to show far transfer.
If you are skilled at playing puzzles on your smartphone or tablet, what does it say about how fast you learn new puzzles, or, more broadly, how well you can focus, say, in school or at work? Or, in the language of psychologists, does “near transfer” predict “far transfer”?
Previous research has described how virtual training produces acute cognitive and neural benefits. Building on those results, a new study suggests that a similar virtual training can also reduce psychosocial stress and anxiety.
