Posted: 24 Jun 2021 01:17 PM PDT

Parents of children with Complex Medical Conditions were five times more likely to report suffering from poor or fair mental than parents of kids without these conditions, and also were more likely to struggle finding help, according to a new study.

Prior research shows 98 percent of employees experience rude behavior at work, but that statistic may be misunderstood, according to new study.

Adolescent marijuana, alcohol use held steady during COVID-19 pandemic

Posted: 24 Jun 2021 10:55 AM PDT

Adolescent marijuana use and binge drinking did not significantly change during the COVID-19 pandemic, despite record decreases in the substances' perceived availability, according to a survey of 12th graders in the United States. The study's findings challenge the idea that reducing adolescent use of drugs can be achieved solely by limiting their supply.

Marmoset study identifies brain region linking actions to their outcomes

Posted: 24 Jun 2021 08:44 AM PDT

The 'anterior cingulate cortex' is key brain region involved in linking behaviors to their outcomes. When this region was temporarily silenced, monkeys did not change behavior even when it stopped having the expected outcome. The finding is a step towards targeted treatment of human disorders involving compulsive behavior, such as OCD and eating disorders, thought to involve impaired function in this brain region.

Non-invasive potential treatment for Alzheimer's disease

Ultrasound can overcome some of the detrimental effects of ageing and dementia without the need to cross the blood-brain barrier, researchers have found.

Children's beat gestures predict the subsequent development of their oral skills

Posted: 24 Jun 2021 08:43 AM PDT

New research shows that the early production of beat gestures with the hands (i.e., gestures normally associated with emphasis that do not represent the semantic content of speech) by infants between 14 and 58 months of age in natural interactions with their carers predicts that in their later development, nearing the age of five, these children obtain better results insofar as their oral narrative skills.

Powerful people are less likely to be understanding when mistakes are made

Those with power, such as the wealthy are more likely to blame others for having shortcomings and they are also less troubled by reports of inequality, according to recent research.

Abnormal response to cellular stress is associated with Huntington's disease

Posted: 23 Jun 2021 04:40 PM PDT

A new study finds that the persistence of a marker of chronic cellular stress, previously associated with neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), also takes place in the brains of Huntington's disease (HD) patients.

AI to track cognitive deviation in aging brains

Posted: 23 Jun 2021 07:02 AM PDT

Researchers have developed an artificial intelligence-based brain age prediction model to quantify deviations from a healthy brain-aging trajectory in patients with mild cognitive impairment, according to a new study. The model has the potential to aid in early detection of cognitive impairment at an individual level.

Protein linked to heart health, disease a potential therapeutic target for dementia

Posted: 23 Jun 2021 06:52 AM PDT

Researchers have found that high levels of a normal protein associated with reduced heart disease also protect against Alzheimer's-like damage in mice, opening up new approaches to slowing or stopping brain damage and cognitive decline in people with Alzheimer's.

Language trade-off? No, bilingual children reliably acquire English by age 5

Posted: 23 Jun 2021 06:13 AM PDT

A new study in U.S.-born children from Spanish-speaking families finds that minority language exposure does not threaten the acquisition of English by children in the U.S. and that there is no trade-off between English and Spanish. Rather, children reliably acquire English by age 5, and their total language knowledge is greater to the degree that they also acquire Spanish. Children's level of English knowledge was independent of their level of Spanish knowledge.

Combining three techniques boosts brain-imaging precision

Posted: 23 Jun 2021 06:12 AM PDT

Researchers have developed a method to combine three brain-imaging techniques to more precisely capture the timing and location of brain responses to a stimulus. Their study is the first to combine the three widely used technologies - fMRI, EEG and EROS - for simultaneous imaging of brain activity.

Recycling of the eye's light sensors is faulty in progressive blindness of older adults

Posted: 23 Jun 2021 06:11 AM PDT

With the National Eye Institute reporting that about 11 million older adults in the U.S. endure a condition that leads to progressive blindness, known as age-related macular degeneration, researchers are starting to understand what goes wrong in the disease, in order to develop new therapies to treat it.

Rap1 controls the body's sugar levels from the brain

Posted: 22 Jun 2021 01:29 PM PDT

Researchers have discovered a mechanism in a small area of the brain that regulates whole-body glucose balance without affecting body weight.

Running to music combats mental fatigue, study suggests

Posted: 22 Jun 2021 09:32 AM PDT

Listening to music while running might be the key to improving people's performance when they feel mentally fatigued a study suggests. The performance of runners who listened to a self-selected playlist after completing a demanding thinking task was at the same level as when they were not mentally fatigued, the research found. The study is the first to investigate the effect of listening to music playlists on endurance running capacity and performance when mentally fatigued.

Genetic cause of neurodevelopmental disorder discovered

Posted: 21 Jun 2021 05:40 AM PDT

Researchers identified a new gene that may be linked to certain neurodevelopmental disorders and intellectual disabilities. The researchers believe that finding genes involved in certain types of developmental disorders, provide an important first step in determining the cause of these disorders and ultimately in developing potential therapies for treating them.
