Story summary

Researchers at Waseda University, Japan, used AI to analyze facial expressions linked to subthreshold depression in students.
The AI software, OpenFace 2.0, tracked 18 Facial Action Units, showing distinct muscle movements associated with mild depressive symptoms.
These movements correlated with depression scores, linking facial expressivity to psychological distress.
Participants with subthreshold depression were rated lower on positive traits, indicating muted expressivity.
The study suggests a non-invasive method for early mental health screening and emphasizes the need for research across diverse populations.
