Study Suggests One in Four Depression Cases Linked to Body Clocks
· World · New Scientist, The Guardian
A new Australian study suggests that roughly 25 percent of people suffering from severe depression may have a distinct subtype linked to dysregulated circadian rhythms. Researchers from the University of Sydney's Brain and Mind Centre analyzed clinical and genetic data from 11,380 Australians and identified a subset termed circadian depression. Symptoms associated with this condition include severe morning fatigue, increased sleep duration during depressive episodes, and a natural preference for staying up late as a night owl. Experts believe recognizing this specific subtype could allow for more targeted treatments, such as melatonin therapies and early morning sun exposure. The findings emphasize that depression is not a uniform illness, paving the way for personalized early intervention strategies.
Why it matters
Patients suffering from circadian-linked depression could receive more effective, targeted treatments instead of standard pharmaceutical approaches.
