The finding
A 2025 US cross-sectional study of adults with OI (“brittle bone disease”) found that 57.7% reported a history of a diagnosed psychiatric condition — most commonly anxiety (42.3%) or ADHD (34.6%). Physical toll is measurable: participants averaged 8.88 surgeries each and scored significantly lower on daily physical functioning.
The striking counterweight: adults with OI scored significantly higher on resilience (“grit”) than the general population, and their current mental-health quality-of-life scores did not differ significantly from the general population. Living with a lifelong fracture risk and building genuine resilience are not contradictions.
Current depression screen positive: 11.5%. Anxiety in OI often runs long: everyone whose current anxiety crossed clinical threshold also had a documented anxiety history. Chronic unpredictability — a hug, a fall, a sneeze as fracture risk — creates a background hum of vigilance.
Why it matters on the Compass
Sonnet frames OI alongside the chronic-illness / medical-trauma cluster: name the vigilance, build a care team that includes mental health, track grit not just fractures, connect with OI communities, separate fracture risk from self-worth, fracture-and-mood logs, coordinated ortho+psych care, educate the people around you.
