Cognitive impairment in people living with HIV not made worse by COVID-19 in those who are vaccinated, US study suggests

A recent US study found that people living with HIV performed worse on cognitive tests after SARS-CoV-2 infection compared to those without HIV, but these differences were attributable to HIV rather than COVID-19. However, vaccinated individuals experienced declines in processing speed following COVID-19.

This is your brain on everyday life

Researchers used functional MRI scanners to monitor brains of subjects watching real-life videos, finding that different parts of the brain work together to understand and remember situations. The study suggests the brain creates mental sketches of people that can be transposed from one location to another.

Psychedelics and Cognition: A New Look

A recent renaissance in psychedelic research investigates the cognitive effects of these drugs, shifting from mathematical modeling to behavioral and clinical studies. Studies have found that psychedelics can increase spontaneous creative insights while decreasing task-specific creativity, as well as affect memories in a malleable way.

The drugs don’t work – meditation and training are better at sparking creativity

Researchers debunk rock'n'roll myth, finding narcotics have no effect on inspiration. Instead, complex training programs, meditation, and cultural exposure boost creativity. Training that highlights mental techniques has long-term impacts, while mindfulness activities like meditation also improve imagination in the short term.

Food insecurity and cognitive trajectories in older adults

A recent study published in JAMA Network Open found that food insecurity is associated with a decline in executive function among older adults. The research used data from 3,037 community-dwelling Medicare beneficiaries and suggests that interventions to increase healthy food access may be crucial in mitigating cognitive decline.

Repetitive negative thinking during low mood linked to suicidal thoughts – new study

A new study has found that increased rumination is a predictor of greater severity of suicidal ideation in young people with major depressive disorder. The study, published in the Journal of Affective Disorders, suggests that elevated cognitive rumination is associated with lower cortical surface area and suicidal ideation.
