We are forging research pathways to lift the ceiling on scientific understanding and to create new interventions so that everyone with bipolar disorder can thrive.

Data are shared and analyzed across genetic background, biological markers, and clinical treatment to drive discovery, reinvest in and improve care, and inspire new research questions.

100 +

Scientists and clinicians in BD²’s network who are transforming the bipolar disorder research landscape.

BD² invests in and connects prominent scientists, clinicians, and people with lived experience to deepen understanding.

$89 Million

Committed in grants to close fundamental gaps in scientific understanding of bipolar disorder.

We implement an intentionally collaborative, open science approach aiming to collapse the timeline from scientific breakthroughs to improved care.

4,000

People with lived experience who will participate in the BD² longitudinal cohort study over the next five years.

Current research, treatment, and care for bipolar disorder lacks scientific precision of the disorder and its diversity. We aim to change that.

About Bipolar Disorder

Bipolar disorder is often studied through the lens of other psychiatric conditions and receives less funding, despite affecting 3% of the global population.

It takes 7 years on average to diagnose bipolar disorder.
It takes 17 years on average to translate a scientific discovery to meaningful interventions for people with bipolar disorder.
Fewer than 50% of individuals find effective treatments.

BD² was created to provide leadership to revitalize and expand the scientific field, implement fundamental direction for research, and offer new hope for those living with bipolar disorder.

Researching previously unknown scientific foundations of bipolar disorder, including biological indicators and genetic mechanisms.
Building the largest collaborative scientific network for bipolar disorder focused on applying learnings to evidence-based, personalized treatment.
Collecting and sequencing the largest and most diverse set of brain samples to expand the understanding of the disorder.

With a collective force focused on transforming bipolar disorder research and care, we see a future where all people with bipolar disorder thrive.

A bipolar diagnosis is identifiable at the onset of proven genetic and biological markers.
Evidence-based treatments are discovered, and improved outcomes are possible for people with bipolar disorder within a short time of diagnosis.
All people with bipolar disorder manage the disorder effectively and thrive in their lives.

Our mission is to accelerate scientific understanding of bipolar disorder and advance clinical care. Our Collaboration Projects provide BD² teams across programs with additional funding to promote data and resource sharing, as well as accelerate new findings.

A message from our Managing Director

"The wonder of science is that while we can’t know where new discovery will come from, we can stack the deck in our favor and aim it towards the greatest impact for people."
