Important Statistics

One in five U.S. adults has a substance use disorder, yet nearly a third of people with depression or anxiety still do not get the care they need, and the resulting pressure is reflected in major market sizes and adoption speeds for digital mental-health solutions. You will also see how telehealth and remote monitoring are cutting costs and readmissions, plus why security, regulatory clearance, and clinician documentation habits are shaping what can scale next.
