| Posted: 01 Jul 2022 10:00 AM PDT Scientists have discovered a convergent mechanism that may be responsible for how two top-ranked genetic risk factors for autism spectrum disorder/intellectual disability (ASD/ID) lead to these neurodevelopmental disorders. |
| Winning by default: Tonsillectomy study shows power of pre-set opioid Rx size Posted: 30 Jun 2022 08:44 AM PDT A small tweak to hospitals' prescribing systems might make a big difference in reducing risk from leftover opioid pain medication, while still making sure surgery patients get relief from their post-operation pain, a new study suggests. |
| Novel gene for Alzheimer's disease in women identified Posted: 30 Jun 2022 05:32 AM PDT Scientists have identified a new gene called MGMT that increases the risk of Alzheimer's in women. |
| Exercise-induced central fatigue -- low oxygen supply clouds judgment Posted: 29 Jun 2022 09:10 AM PDT Research on the effects of exercise in low-oxygen environments on the brain demonstrated that cognitive performance worsens when lower-than-usual amounts of oxygen are carried by the blood. Consequently, tissue in brain regions with less critical functions may receive inadequate oxygen supply to maintain normal activity levels. |
| When more is more: Identifying cognitive impairments with multiple drawing tasks Posted: 29 Jun 2022 05:40 AM PDT Researchers have found that extracting drawing features from a combination of five drawing tasks -- rather than from any single task alone -- leads to more accurate classification of people with normal cognition, mild cognitive impairment, and Alzheimer's disease by capturing different, complementary aspects of cognitive impairments. Their proposed portable, easy-to-use screening test may improve patient diagnosis, leading to earlier and more effective treatments. |
| Predicting the future: A quick, easy scan can reveal late-life dementia risk Posted: 26 Jun 2022 05:02 PM PDT Researchers have discovered an important link between vascular health and late-life dementia, discovering the calcification of plaques within the abdominal aorta to be a reliable marker for late-life dementia. |
