Australian Study Identifies New Depression Subtype Linked to Body Clock Disruptions

• Australian researchers identified a new subtype of depression called 'circadian depression'.
• Circadian depression is linked to disruptions in the body's internal clock.
• This subtype affects nearly a quarter of over 11,000 participants in the study.
• Circadian depression may be less responsive to traditional antidepressant treatments.
• The study suggests these symptoms may cluster in a distinct subtype of depression.
