Digital epidemiology: leveraging social media for insight into epilepsy and mental health

Paper by Liza Dahiya & Rachit Bagga: “Social media platforms, particularly Reddit’s r/Epilepsy community, offer a unique perspective into the experiences of people with epilepsy (PWE) & their caregivers.

To quantify engagement within the community, we introduce a novel metric, F(P), which integrates post length, sentiment polarity, and readability. Posts expressing emotional or mental health concerns show significantly higher F(P) scores, underscoring the platform’s potential as a real-time support and outreach mechanism…(More)”.
