When it comes to coping with climate change, there may be two types of people: those who take action to try to improve the environment and those who don't bother because they don't believe their actions will make a difference.

The COVID-19 pandemic caused a spike in depression and anxiety in expectant mums, a new study has revealed. There was an increase in reported depression rates of 30 per cent from pre-pandemic levels, from 17 per cent to 47 per cent -- with anxiety rates also jumping up 37 per cent in expecting mothers to 60 per cent.

More than half of nurses had difficulty sleeping during the first six months of the COVID-19 pandemic -- and getting less sleep increased their odds of experiencing anxiety and depression, according to a new study.

Signs of inflammation in the blood reliably predict and identify severe depression in pregnancy, reports a new study.

In a 50-state survey-based study, adults with depressive symptoms were twice as likely to support misinformation about COVID-19 vaccines. People who endorsed false statements were half as likely to be vaccinated against COVID-19.

High school students who have trouble paying attention in class are more likely to admit to cheating, a new study shows.

Researchers recruited 100 women, 73 of whom they followed from the start of the third trimester to three months postpartum. They analyzed subjective and objective measures of sleep, biological rhythms, melatonin levels, and light exposure using a variety of tools, including questionnaires, actigraphs (wearable sleep monitors), laboratory assays, and other methods.

Scientists have discovered new links between the breakdown in brain cell development and the risk of schizophrenia and other psychiatric disorders.

A new study has found that people who experienced increased stress, anxiety and depression at the start of the pandemic, were at greater risk of getting COVID-19. The research found that greater psychological distress during the early phase of the pandemic was significantly associated with participants later reporting SARS-CoV-2 infection, a greater number of symptoms and also more severe symptoms.

Researchers have identified the effects of an environmental stressor, sleep deprivation, that could alter the balance controlled by antipsychotic drugs and impact individuals with schizophrenia.
