| Anxiety cues found in the brain despite safe environment Posted: 13 Nov 2021 04:25 AM PST Researchers used a virtual-reality environment to understand the impact anxiety has on the brain and how brain regions interact with one another to shape behavior. |
| Vascular defects appear to underlie the progression of Parkinson's disease Posted: 13 Nov 2021 04:22 AM PST In an unexpected discovery, researchers have identified what appears to be a significant vascular defect in patients with moderately severe Parkinson's disease. The finding could help explain an earlier outcome of the same study, in which the drug nilotinib was able to halt motor and non-motor (cognition and quality of life) decline in the long term. |
| Best way to avoid procrastination Posted: 13 Nov 2021 04:22 AM PST They say procrastination is the thief of time -- actually deadlines are. New research has found that if you want someone to help you out with something, it is best not to set a deadline at all. But if you do set a deadline, make it short. |
| Team engineers new way to get medication past blood-brain barrier Posted: 12 Nov 2021 09:15 AM PST A team of researchers has developed a new technique to open the blood-brain barrier temporarily to deliver medication to the brain. Getting medication past the brain's unique and protective blood vessels, known as the blood-brain barrier, is one of the biggest challenges in treating brain and central nervous system diseases, according to researchers. The technique uses light and nanoparticles to pry open temporarily these barriers -- called tight junctions -- to allow medication to reach its target. |
| Conflicting health information compromises attention and emotional responses Posted: 11 Nov 2021 12:42 PM PST The 24-hour news cycle and social media bombardment often resulting in conflicting messages about health issues might be making it harder than ever for people to make critical decisions, according to a new study. |
| Students who repeat a grade experience more bullying, study finds Posted: 11 Nov 2021 12:42 PM PST Students who have repeated a grade have higher risks of being victims of bullying in countries around the world, according to a new study of nearly half a million students. |
| ‘Dancing molecules’ successfully repair severe spinal cord injuries Posted: 11 Nov 2021 12:36 PM PST Researchers have developed an injectable therapy based on nanofibers that has enabled paralyzed mice with severe spinal cord injuries to regain the ability to walk. |
| Gut microbiota differences seen in people with autism may be due to dietary preferences Posted: 11 Nov 2021 10:03 AM PST Research suggested that autism spectrum disorder (ASD) may be at least partly caused by differences in the composition of the gut microbiota, based on the observation that certain types of microbes are more common in people with autism. But a new study suggests that the link may actually work the other way around: the diversity in species found in the guts of children with autism may be due to their restricted dietary preferences associated with autism, rather than the cause of their symptoms. |
| New imaging biomarkers predict antidepressant response Posted: 09 Nov 2021 10:50 AM PST The outcome predictive models were developed in part using data from a large multi-center study. The findings provide strong evidence that the current trial-and-error approach used in clinical practice for the selection of the right antidepressant can be replaced with this new precision medicine approach. |
| Listening to favorite music improves brain plasticity Posted: 09 Nov 2021 09:03 AM PST Researchers have demonstrated that repeated listening to personally meaningful music induces beneficial brain plasticity in patients with mild cognitive impairment or early Alzheimer's disease. |
| Diagnosis of Alzheimer’s and related dementias reduces social activity, study suggests Posted: 09 Nov 2021 06:53 AM PST Despite the belief that early diagnosis of Alzheimer's disease and other dementias is crucial, a new study found that the diagnosis may unintentionally impact social relationships and activity. |
| Can talking to young children during TV time buffer screen time effects on development? Posted: 08 Nov 2021 10:08 AM PST The more parents engaged in conversation with preschoolers during shared TV time, the more likely those children were to have higher curiosity levels when they reached kindergarten, a new study suggests. This was particularly true for children with socioeconomic disadvantages. |
