The fear of rejection -- familiar to many children and adults -- can significantly impact how kids behave in their peer groups, according to new research.

Exposure to fine particulate air pollution (PM2.5) from wildfire smoke was associated with increased visits to emergency departments (ED) for mental health conditions, according to a new study.

Retired adults who habitually exercised outperformed sedentary adults in physical and cognitive tests.

Early administration of the drug Fosdenopterin/rcPMP improves the chances of survival of infants with MoCD type A and promotes the development of brain functions.

A global study establishes long-term risk of stroke. Findings shows one in five people who experience a minor stroke or TIA will have another stroke within 10 years.

Researchers have developed a method that shows how the nervous system and sensory organs are formed in an embryo. By labeling stem cells with a genetic 'barcode', they have been able to follow the cells' developmental journey and discover how the inner ear is formed in mice. The discovery could provide important insights for future treatment of hearing loss.

New research shows that Sat Nav systems are helping keep older drivers on the roads for longer. The study reveals that over 65s with a poorer sense of direction rely more on help from GPS navigation systems such as Sat Nav or smartphone maps. Those using GPS tended to drive more frequently -- suggesting that the technology helps older people maintain driving independence.

New research shines light on how the brain interprets nutritional and hydration needs and turns them into action.

Fluency in a foreign language is often thought to be about speaking quickly and using advanced vocabulary. However, researchers reveal that speakers who use common, everyday expressions sound more fluent than those who rely on rare, complex words. The study highlights the importance of mastering familiar phrases to improve fluency perception, suggesting that learners should naturally incorporate common formulaic expressions in spontaneous speech.

Parkinson's doesn't just affect movement and the brain -- it may also impact the heart, according to new research. Scientists suggest that targeting a key protein outside of the brain could help manage Parkinson's-related heart issues.

There are over six million Americans with heart failure who are at greater risk of losing their cognitive abilities earlier in life, a study suggests. Global cognition and executive functioning declined more rapidly over the years after heart failure diagnosis, as people with the condition mentally aged the equivalent of 10 years within just seven years of a heart failure diagnosis.

In a new extensive systematic review, researchers identified 17 modifiable risk factors that are shared by stroke, dementia, and late-life depression. Modifying any one of them can reduce your risk of all three conditions. The findings provide evidence to inform novel tools such as the Brain Care Score.

Differences in the distribution of certain proteins and markers in the brain may explain why some people first experience vision changes instead of memory loss in Alzheimer's disease, finds a new study.

Organoids have revolutionized science and medicine, providing platforms for disease modeling, drug testing, and understanding developmental processes. While not exact replicas of human organs, they offer significant insights. Scientists now present a new organoid model that reveals details of the developing nervous system's response to viral infections, such as Rubella. This model could influence pharmaceutical testing, particularly benefiting drug safety for pregnant women.

Cervical artery dissection is a tear in an artery in the neck that provides blood flow to the brain. Such a tear can result in blood clots that cause stroke. A new study has found almost a five-fold increase in the number of U.S. hospitalizations for cervical artery dissection over a 15-year period.

For the first time researchers demonstrate in an animal how heavy alcohol use leads to long-term behavioral issues by damaging brain circuits critical for decision-making.

Researchers have successfully developed a novel drug to restore vision. The treatment method restores vision through retinal nerve regeneration.

Scientists should experiment with creative ways of communicating their work to inspire action to protect the natural world, researchers say.

An AI tool that analyzes nurses' data and notes detected when patients in the hospital were deteriorating nearly two days earlier than traditional methods and reduced the risk of death by over 35%.

Researchers have demonstrated how specific biomarkers in the blood can predict the development of dementia up to ten years before diagnosis, among older adults living independently in the community.

Researchers have gained a new understanding of how the brain processes reward and risk information. Neuroscientists show how nerve cells in the so-called amygdala not only encode the probability and magnitude of rewards, but also dynamically process this information to predict value and risk. The findings provide new insights into the neural basis of decision-making and could also be important for understanding mental illnesses such as anxiety disorders and depression.

A new analysis of a vaccination program in Wales found that the shingles vaccine appeared to lower new dementia diagnoses by 20% -- more than any other known intervention.

A newly published study found that a mother's exposure to phthalates during pregnancy can affect their newborn's metabolism and brain development. These widely used plasticizers are commonly found in a variety of cosmetics and personal care products, such as shampoos, soaps, and detergents, as well as plastic food and beverage containers.

Despite a recent Food and Drug Administration warning against inhaling nitrous oxide, commonly known as laughing gas, deaths due to misusing the substance are rising in the United States.

In mice, autism symptoms arise when a certain pair of competing nerve proteins falls out of equilibrium, according to a new study.
