A 2026 study in Journal of Medical Internet Research by Evkoski et al analyzed 114 Reddit communities drawn from the 20,000 most active subreddits in 2022 to map associations among 49 disorders across nine ICD F-code categories. Using a bipartite configuration model with Bonferroni correction, they found a dense network (density=0.135), identified central disorders (PTSD, OCD, depersonalization-derealization), and reported only 13% edge overlap with ICD diagnostic relationships (Adjusted Rand Index=0.295).
