Paradoxical lucidity, the phenomenon where some with severe dementia suddenly regain their memory and exhibit normal behaviors immediately prior to death, may help shed new light on the mechanisms of Alzheimer's disease.
Middle-school aged children with vitamin D deficiency were twice as likely to develop externalizing behavior problems and mood disorders during adolescence than their peers with higher levels of the vitamin.

The brain quickly transitions from one network to another in regular patterns. The transition trajectories constitute a temporal circuit where the conscious brain cycles through a structured pattern of states over time.
Community actions taken to slow the spread of COVID-19 may help to contain the virus and stop the exponential growth of cases. Researchers say the viral spread in China occurred in a fractal pattern. When social distancing was implemented, viral spread slowed. With more communities adopting social distancing measures, the spread became smaller in each new area exposed.
Common coronaviruses are usually detected between December and May, with a peak of infection during January and February. Only 2.5% of cases occurred in the summer months. Researchers caution it is still too early to tell if COVID-19 will follow the same seasonal path as other coronaviruses.
A medical wrist device detected disrupted sleep patterns 24 hours before participants started shedding the flu virus. While the initial study was focused on influenza, researchers speculate the device could be sufficient at spotting the beginning of other infections, including COVID-19. While it should not be considered a full diagnostic device, the wristband data will be useful to guide when people should self isolate as a precaution.
Researchers report that if the US had adopted mandatory BCG vaccines against tuberculosis decades ago, we may not have reached death rates in triple digits for coronavirus. Countries that have a current policy mandating BCG vaccinations have significantly slower growth of both COVID-19 cases and deaths compared to countries with no mandates for the TB vaccination.
People who experience a spinal cord injury have an increased risk of developing a mental health disorder, a new study reports. Those with SCI had higher instances of anxiety, depression, and psychological multimorbidity than those who had not experienced a debilitating injury.
Patients with severe COVID-19 infections have higher blood levels of neutrophil extracellular traps (NETs), which produce NETosis, an inflammatory type of neutrophil cell death. Researchers believe the NETs may be relevant to numerous aspects of novel coronavirus as thrombosis and inflammation are hallmarks of the severe infection.
