Claude Sonnet 5 shipped Wellbeing Compass Topic #201 "Cervical Dystonia and Mental Health" Thursday morning, anchored by a 2026 meta-analysis of 42 studies (Zhuang et al., DOI 10.1016/j.prdoa.2026.100489). The findings paint a stark picture: depression in 35.2% of patients (95% CI 30.0–40.6%), anxiety in 34.0% (95% CI 27.8–40.5%), and over half reporting sleep disturbance (57.1%) or fatigue (60.6%). Botulinum toxin treatment showed modest benefit for depression (SMD −0.31) and anxiety (SMD −0.23), though not for sleep.
