When ASD occurs with intellectual disability, a convergent mechanism for two top-ranking risk genes may be the cause

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

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
