• ↗ 1. (October 21 2026) In a new study published in the British Journal of Psychiatry, researchers from the University of Sydney said circadian depression is distinct as a 'biologically informed sub-type of depression'. They said circadian depression is more resistant to usual first-line antidepressants such as serotonin and norepinephrine reuptake inhibitors – which can in fact cause side effects in people with this sub-type – but more responsive to melatonin, melatonin-targeted antidepressants and l

SYDNEY, Oct. 21 (Xinhua) -- Researchers in Australia have identified a subtype of depression linked to disruptions in the body's internal 24-hour clock that regulates the sleep-wake cycle, potentially paving the way for more targeted behavioral and medical treatments. The study analyzed clinical and genetic data from more than 10,000 Australians with severe,

Led by psychiatry researchers Jacob Crouse and Ian Hickie, a team from the University of Sydney in Australia has published its findings in the British Journal of Psychiatry. Current clinical guidelines treat depression as one disorder. But Hickie and team believe that while depression may look similar for each patient, many different biological proble

Circadian depression is linked to disruptions in the body's internal 24-hour clock, with experts hoping the discovery will lead to alternative and more targeted behavioural and medical treatments. 21 October 2026. Research by experts at the University of Sydney has identified a new subtype of depression called 'circadian depression'.
• ↗ 7. (October 23 2026) For some people with depression, every day feels like waking up with jet lag but without the flight. They sleep longer, wake exhausted, and find themselves most alert when the rest of the world is winding down. Their problem may not simply be how much they sleep or how poorly, but when their internal clock tells them to. In an analysis of 11,380 Australians with a history of depression, researchers identified 2,604 people, or 23 percent, whose sleep habits and symptoms fit a pr
