The survival of the fittest might just be the survival of the steadfast instead. Researchers say having a positive attitude is advantageous in a computational model that simulates evolution.

Depression and anxiety disorders are highly prevalent and disabling disorders, which result not only in an enormous amount of human misery and lost health, but also lost economic output. Here we propose a global investment case for a scaled-up response to the public health and economic burden of depression and anxiety disorders.

Very little is currently known about air pollutants’ adverse effects on neurodegenerative diseases even though recent studies have linked particulate exposures to brain pathologies associated with Parkinson’s and Alzheimer’s disease. In the present study, we investigated long-term exposure to traffic-related air pollution and Parkinson’s disease.

Exposure to ambient air pollution is suspected to cause cognitive effects, but a prospective cohort is needed to study exposure to air pollution at the home address and the incidence of dementia. The researchers aimed to assess the association between long-term exposure to traffic-related air pollution and dementia incidence in a major city in northern Sweden.

Mild cognitive impairment (MCI) describes the intermediate state between normal cognitive aging and dementia. Adverse effects of air pollution (AP) on cognitive functions have been proposed, but investigations of the simultaneous exposure to noise are scarce. The objective of the study was to analyze the cross-sectional associations of long-term exposure to AP and traffic noise with overall MCI, amnestic (aMCI) and non-amnestic (naMCI) MCI.

Exposure to traffic noise has been associated with adverse effects on neuropsychological outcomes in children, but findings with regard to behavioral problems are inconsistent. The researchers investigated whether residential road traffic noise exposure is associated with behavioral problems in 7-year-old children.
