Complex Disorders Alliance

The body's structure influences more than stability and movement. At CODA, we are studying how connective tissue, the craniocervical region, and mechanical forces may influence communication between the nervous, vascular, and immune systems.

Structural Mechanics & Instability is one of five interconnected research domains within CODA's Neuroimmune Research Portfolio. Together, these domains investigate the biological mechanisms underlying complex chronic disorders across diagnostic categories.

CODA is funding research to better understand how connective tissue health, craniocervical function, and biomechanical forces may influence neural, vascular, and immune signaling. This work investigates how structural and mechanical factors may affect whole-body function and contribute to the biological processes involved in complex chronic illness.

The brain depends on continuous circulation, oxygen delivery, and waste clearance to function properly. At CODA, we are studying what happens when those systems become impaired.

CSF, Glymphatics, Cerebral & Venous Blood Flow is one of five interconnected research domains within CODA’s Neuroimmune Research Portfolio. Together, these domains investigate the biological mechanisms underlying complex chronic disorders across diagnostic categories.

CODA is funding research to better understand how disruptions in cerebrospinal fluid flow, glymphatic clearance, vascular circulation, and oxygen delivery may contribute to neurological and systemic symptoms in complex, chronic disorders. This work investigates how impaired brain clearance and blood flow may affect cognition, fatigue, autonomic function, and overall health.

For many patients, chronic illness begins with an infection that never seems to fully resolve. At CODA, we are studying how viral persistence, latent viral reactivation, and microbial disruption may contribute to ongoing immune activation and chronic symptoms after an acute infection has passed.

Viral and Microbial Persistence is one of five interconnected research domains within CODA’s Neuroimmune Research Portfolio. Together, these domains investigate the biological mechanisms underlying complex chronic disorders across diagnostic categories.

CODA is funding research to better understand how persistent viral antigens, reactivated latent viruses, microbiome disruption, and chronic immune engagement may contribute to long-term illness. This work investigates biological mechanisms that have been implicated in conditions such as Long COVID, ME/CFS, and related disorders.

Advancing the deep understanding of complex chronic disorders begins with understanding how the body's systems work together.

By supporting research across interconnected domains - including neuroimmune signaling, immune network dysfunction, vascular biology, autonomic regulation, and structural health - CODA is helping advance the scientific knowledge needed to inform future diagnostics and treatments available to patients.

These studies are designed to generate evidence that advances scientific understanding and helps inform better treatments for individuals living with Long COVID, ME/CFS, POTS/dysautonomia, craniocervical dysfunction, and related complex chronic conditions.

The immune system is designed to activate in response to a threat and then return to balance. At CODA, we are studying what happens when the mechanisms that regulate that process stop functioning properly.

Immune Network Dysregulation is one of five interconnected research domains within CODA’s Neuroimmune Research Portfolio. Together, these domains investigate the biological mechanisms underlying complex chronic illness across diagnostic categories.

CODA is funding research to better understand immune dysregulation, including how immune pathways become activated, suppressed, misdirected, or unable to return to balance in complex chronic illness. This work investigates how disruptions in immune regulation may contribute to persistent inflammation, hypersensitivity, and multisystem symptoms across patient populations.

For many patients living with EDS and complex chronic conditions, survival becomes the baseline.

Daily life is shaped by symptoms, limitations, and uncertainty. Even with a diagnosis, patients are often left without clear or effective treatment pathways.

This reflects a fundamental gap in how these conditions are studied.

Progress depends on research that connects biological systems, identifies underlying mechanisms, and translates that understanding into more precise treatment approaches.
At CODA, this is the focus of our work.

Advancing this research requires sustained investment.

At CODA, we believe every patient deserves answers. That starts with understanding the biology contributing to their symptoms.

CODA's Neuroimmune Research Portfolio is built around five interconnected research domains that study complex chronic illness as a whole, not by a single diagnosis.

CODA is funding research to better understand how disrupted communication between the nervous system and immune system may drive chronic illness and persistent symptoms. This work explores how targeted treatments may help restore healthier signaling and improve symptoms for a certain subgroup of patients.

Every person living with ME/CFS, Long COVID, POTS, EDS, MCAS, and/or other complex, chronic disorders deserves a research strategy that matches the needs of their biology.

That's exactly what CODA is building: multisystem research for multisystem conditions.

Our research is organized around five core neuroimmune domains, the interconnected biological systems most consistently involved in complex chronic disease. Together, they form a scientific framework built to do what medicine has yet to deliver for this community: subtype patients by biology and match the right treatment to the right person at the right time.

Progress is possible. This is how we get there. This research framework drives every study and initiative CODA funds.
