| Molecular basis of deep sleep pinpointed, suggests avenues for novel treatments Posted: 29 Apr 2022 11:50 AM PDT Scientists pinpoint the molecular epicenter of deep-sleep regulation. The findings, based on research in mice, identify a gene that makes a protein that regulates delta waves -- electrical signals between neurons that occur during the deepest phases of relaxation and are a hallmark of restorative sleep. |
| New sleep molecule discovered: 'It shows just how complex the machinery of sleep is' Posted: 29 Apr 2022 11:49 AM PDT Researchers presents a new study demonstrating that a small molecule in brain cells affects the level of hypocretin, which is responsible for making us feel awake during the day and tired at night. People with a genetic variation of this molecule have a higher risk of suffering from daytime sleepiness. |
| Stress, anxiety and depression during pregnancy may hinder toddler's cognitive development Posted: 29 Apr 2022 11:49 AM PDT Women's elevated anxiety, depression and stress during pregnancy altered key features of the fetal brain, which subsequently decreased their offspring's cognitive development at 18 months. These changes also increased internalizing and dysregulation behaviors, according to a new study. Researchers followed a cohort of 97 pregnant women and their babies. The findings further suggest that persistent psychological distress after the baby is born may influence the parent-child interaction and infant self-regulation. |
| New studies show special mental health risks for certain groups of new doctors Posted: 29 Apr 2022 11:49 AM PDT First-year surgery residents, and first-year medical residents in all fields who are members of sexual minorities such as LGBTQ, are more likely than others to develop depression during the stressful training period. |
| New research helps explain how Ritalin sharpens attention Posted: 29 Apr 2022 11:49 AM PDT Researchers found animals that had taken methylphenidate performed better on a visual task of attention, and that the improvement happened exactly when that same metric of neuron activity shifted. |
| 'Eye-catching' smartphone app could make it easy to screen for neurological disease at home Posted: 29 Apr 2022 11:49 AM PDT Researchers have developed a smartphone app that could allow people to screen for Alzheimer's disease, ADHD and other neurological diseases and disorders -- by recording closeups of their eye. The app uses a smartphone's built-in near-infrared camera and selfie camera to track how a person's pupil changes in size. These pupil measurements could be used to assess a person's cognitive condition. |
| A new mutation behind synucleinopathies Posted: 29 Apr 2022 11:48 AM PDT Scientists have carried out an extensive study of a newly discovered mutation that can uncover new insights into the molecular basis of pathology formation in a family of disorders that includes Lewy body dementia and Parkinson's disease. |
| High-frequency spinal cord stimulation shows improved longer lasting pain relief Posted: 28 Apr 2022 01:16 PM PDT Researchers at UC San Diego School of Medicine report that high-frequency spinal cord stimulation proved more effective at improving perceived pain reduction than low-frequency SCS in patients studied, and that there was some variation in PPR between male and female patients. |
| Findings open way for personalized MS treatment Posted: 27 Apr 2022 11:06 AM PDT Currently available therapies to treat multiple sclerosis (MS) lack precision and can lead to serious side effects. Researchers have now developed a method for identifying the immune cells involved in autoimmune diseases, and have identified four new target molecules of potential significance for future personalized treatment of MS. |
| Talk therapy may alleviate depression and improve quality of life for people with dementia Posted: 25 Apr 2022 06:20 PM PDT Talking therapies may improve symptoms of depression for people with dementia, finds a new review, providing hope for a group who typically do not benefit from antidepressants. |
