Article Summary
A landmark 2026 study in The Lancet — analyzing data from 204 countries — found mental health disorders are now the leading cause of disability worldwide, accounting for 17% of all years lived with disability globally in 2023. An estimated 1.17 billion people were affected that year, nearly double the 1990 figure. Anxiety disorders and major depressive disorder are the top drivers. Researchers point to structural forces — poverty, instability, violence, and eroding social connection. The Hudson Valley Care Coalition’s Social Care Network (SCN) addresses these drivers directly, connecting Medicaid members to food, housing, transportation, and social care support. People with serious mental illness are a priority population for SCN services. Medicaid members can self-screen at hudsonvalleycare.org/self-screener/.

The Numbers Are Hard to Ignore
A major new study published in The Lancet has put a global number on what clinicians have long seen in the exam room: mental health disorders are now the leading cause of disability worldwide.
Researchers analyzed data from 204 countries and estimated that 1.17 billion people were living with a mental health condition in 2023 — nearly double the number in 1990. Mental disorders are now the single largest source of disability burden worldwide — ahead of cardiovascular disease, cancer, and every other condition tracked in the study.
Anxiety disorders and major depressive disorders are the primary drivers. Teens between 15 and 19 carry the highest burden of any age group — a particularly troubling finding given that this is the period when life trajectories around education, employment, and relationships are being shaped. Women are disproportionately affected across nearly every measure.
The study’s authors are clear that this isn’t simply a clinical access problem. The structural conditions people live in — poverty, housing insecurity, violence, and the collapse of social connection — are driving the crisis just as much as anything happening inside a provider’s office.
Mental Health Doesn’t Happen in a Vacuum
The research confirms something the social care field has argued for years: you cannot meaningfully treat mental health in isolation from the conditions that
shape it.
Food insecurity fuels anxiety. Housing instability triggers and deepens depression. Isolation — the kind that comes from not having transportation, not having community, not having support — compounds everything. These aren’t contributing factors at the margins. They are central to why people get sick and why they stay sick.
“What we’re seeing in the data confirms what our behavioral health providers have known for years — that mental health and social circumstance are inseparable. When someone is struggling to meet their basic needs, their mental health suffers. And when mental health suffers, everything else gets harder. We have to address both sides of that equation.”

What the Social Care Network Is Doing About It
The Hudson Valley Care Coalition’s Social Care Network (SCN) was built on this premise: that health — including mental health — starts in the community-based clinics.
The SCN connects Medicaid members across seven Hudson Valley counties to services addressing the root conditions driving poor health: food support, housing assistance, transportation, and social care navigation. For people living with or at risk of mental health challenges, these aren’t secondary concerns. They are often the most direct lever available.
Medicaid members with serious mental illness are a priority population for SCN services — meaning they have a direct pathway to enhanced support and coordinated navigation.
“The Social Care Network exists because healthcare alone can’t solve this. When we screen someone and find out they’re food insecure or about to lose their housing, connecting them to real support isn’t just the compassionate thing to do — it’s clinically meaningful. It changes outcomes.”
— Meghan Weygant, Chief Operating Officer, HVCC
What Providers Can Do Right Now
If you’re a behavioral health provider in the Hudson Valley, the most actionable step you can take is contacting HVCC to gather information on community-based organizations that are part of the Social Care Network and then make direct referrals to such organizations. The screening tool is standardized. SCN navigators handle coordination from there. This isn’t about adding workflow burden — it’s about making the clinical work you’re already doing go further.

Frequently Asked Questions
Are mental health disorders really the leading cause of disability worldwide? Yes, according to the 2023 Global Burden of Disease study published in The Lancet. Mental disorders are now the leading cause of years lived with disability (YLDs) globally — accounting for more than 17% of all disability burden. They ranked second as recently as 1990.
How many people are affected by mental health disorders globally? An estimated 1.17 billion people were living with a mental health disorder in 2023, according to the Lancet study. That represents nearly double the number recorded in 1990, and accounts for roughly one in seven people on the planet.
What mental health conditions are driving the increase? Anxiety disorders and major depressive disorder are the leading contributors to the global mental health burden. The study also found notable increases in dysthymia, schizophrenia, anorexia nervosa, bulimia nervosa, and conduct disorder over the study period.
Why are teens and young people especially affected? The Lancet study found that the 15–19 age group carries the highest mental health burden of any age group globally. This is a critical developmental window — disruptions here can affect educational attainment, employment, and relationships for years to come.
Why are women more affected than men? The study found higher disability rates among women across nearly all mental disorders. Researchers point to caregiving pressures, gender inequality, and disproportionately high rates of trauma and abuse as contributing factors.
What does social need — food, housing, transportation — have to do with mental health? Quite a lot. The Lancet researchers explicitly identify poverty, insecurity, and declining social connectedness as structural drivers of the mental health crisis — not just consequences of it. Addressing these conditions is increasingly understood as essential to mental health treatment and prevention, not separate from it.
What is the Social Care Network (SCN) and how does it help? The SCN is a network of community organizations and providers working across seven Hudson Valley counties to connect Medicaid members to services addressing unmet social needs — food, housing, transportation, and navigation support. It is part of New York State’s 1115 Waiver program, led locally by the Hudson Valley Care Coalition (HVCC).
Can someone with a mental health condition get help through the SCN? Yes. Medicaid members with serious mental illness are among the SCN’s priority populations and have a direct pathway to enhanced services and coordinated support.
How do I find out if I qualify? Medicaid members in the Hudson Valley can self-screen at hudsonvalleycare.org/self-screener/.
I’m a behavioral health provider. How do I connect patients to the SCN? Contact HVCC to learn how to make referrals to organizations that are part of the Social Care Network or inquire about our co-location model.
