| Diagnosing sports-related concussions may be harder than thought Posted: 05 Apr 2022 02:18 PM PDT The tool being used to diagnose concussions might be overestimating the condition and wrongly identifying symptoms like fatigue and neck pain caused from intense exercise and not a brain injury, according to researchers. This new research raises new questions about the Sport Concussion Assessment Tool (SCAT), a questionnaire widely used along with other methods to diagnose concussions sustained during sports. |
| Posted: 05 Apr 2022 02:18 PM PDT Researchers have discovered 15 'hotspots' in the genome that either speed up brain aging or slow it down -- a finding that could provide new drug targets to resist Alzheimer's disease and other degenerative brain disorders, as well as developmental delays. |
| Loud and clear: High-energy ads keep viewers tuned in, study shows Posted: 05 Apr 2022 02:17 PM PDT More energetic commercials are likely to be tuned in more or avoided less by viewers, according a new study. |
| Posted: 05 Apr 2022 11:35 AM PDT They are part of the brain of almost every animal species, yet they remain usually invisible even under the electron microscope. |
| How left brain asymmetry is related to reading ability Posted: 05 Apr 2022 11:35 AM PDT Researchers report that two seemingly opposing theories of language processing are both correct. The study shows that greater left-brain asymmetry can predict both better performance and average performance on a foundational measure of reading ability, depending on whether analysis is conducted over the whole brain or in specific regions. |
| Reproductive factors and dementia risk Posted: 05 Apr 2022 11:35 AM PDT Pregnancy, long reproductive span, and older age at menopause are associated with a lower risk of dementia in women, according to a new study. Inversely, hysterectomy, younger age of first birth, and younger or older than average age at first period were associated with greater dementia risk. |
| Women seen as happy and men as angry despite real emotions Posted: 05 Apr 2022 09:39 AM PDT Faces and voices are more likely to be judged as male when they are angry, and as female when they are happy, new research has revealed. The study found that how we understand the emotional expression of a face or voice is heavily influenced by perceived sex, and vice versa. He said: "This study shows how important it is not to rely too much on your first impressions, as they can easily be wrong. "Next time you find yourself attributing happiness or sadness to a woman be aware of your bias and possible misinterpretation." |
| People with epilepsy live shorter lives Posted: 05 Apr 2022 09:39 AM PDT On average, people with epilepsy live 10-12 years fewer than those who do not have the condition. Excess mortality is particularly pronounced among people with epilepsy and mental disorders. |
| Miniature brain models: Understanding autism Posted: 05 Apr 2022 09:39 AM PDT Scientists use brain organoids to understand how a mutated gene affects brain development. |
| Alpha brain waves can predict post-surgery pain Posted: 05 Apr 2022 09:39 AM PDT Patients who are most likely to suffer severe pain following an operation can be reliably identified using a new technique. |
| Newborn cells in the epileptic brain provide a potential target for treatment Posted: 05 Apr 2022 09:39 AM PDT Scientists presents evidence that adults can generate new brain cells, and that this process is dramatically altered in patients with long-term epilepsy. The study details the presence of newborn neurons and an immature version of a related cell type, known as astroglia, in patients with epilepsy, furnishing new evidence of neurogenesis in adults and new insights into how immature astroglia might contribute to epilepsy. The study also opens an unexplored avenue toward the development of new anti-seizure medications for millions of people. |
| Late-onset alcohol abuse can be a presenting symptom of dementia Posted: 05 Apr 2022 07:29 AM PDT Clinical awareness of connection between alcohol and dementia is paramount to providing the best patient care management. |
| Disbelief in human evolution linked to greater prejudice and racism Posted: 04 Apr 2022 01:46 PM PDT A disbelief in human evolution was associated with higher levels of prejudice, racist attitudes and support of discriminatory behavior against Blacks, immigrants and the LGBTQ community in the U.S., according to recent research. |
| The art of smell: Research suggests the brain processes smell both like a painting and a symphony Posted: 04 Apr 2022 01:45 PM PDT What happens when we smell a rose? How does our brain process the essence of its fragrance? Is it like a painting -- a snapshot of the flickering activity of cells -- captured in a moment in time? Or like a symphony, an evolving ensemble of different cells working together to capture the scent? New research suggests that our brain does both. |
| Millionaires more risk-tolerant and emotionally stable Posted: 04 Apr 2022 12:27 PM PDT Millionaires are more risk-tolerant, emotionally stable, open, extroverted, and conscientious than the general population, according to new research. |
| Firefighters with PTSD likely to have relationship problems Posted: 04 Apr 2022 12:01 PM PDT The stress firefighters face takes a toll. New research finds that those with Post Traumatic Stress Disorder are likely to have relationship problems due to an inability to regulate emotions. |
| Middle ear fluid common in kids on ventilators Posted: 04 Apr 2022 12:01 PM PDT Babies and toddlers who need a tracheostomy -- a tube surgically inserted into their windpipe to help relieve breathing problems -- are at a high risk of accumulating fluid behind their eardrum when on a ventilator. That's the conclusion of a new study by head and neck surgeons. This buildup of fluid, called a middle ear effusion, can put them at risk for ear infections, hearing loss, and delays in speech and language development. |
| Loss of neurons, not lack of sleep, makes Alzheimer’s patients drowsy Posted: 04 Apr 2022 09:05 AM PDT The lethargy that many Alzheimer's patients experience is caused not by a lack of sleep, but rather by the degeneration of a type of neuron that keeps us awake, according to a study that also confirms the tau protein is behind that neurodegeneration. |
| Teens more likely to disengage from school after police stops Posted: 04 Apr 2022 06:30 AM PDT Teens who are stopped by the police are more likely to report greater disengagement from school the next day, and racial and ethnic minority youth reported more invasive police encounters than white youth, according to new research. |
| Opioid prescriptions for pediatric patients following surgical procedures have dropped significantly Posted: 04 Apr 2022 05:28 AM PDT Researchers found that opioid prescriptions for children who underwent one of eight common outpatient surgeries declined over a period of five years. These findings suggest that clinicians are using more discretion when considering which pediatric patients require an opioid prescription after their procedures. |
