Beyond Celiac is advancing research that reframes celiac disease as a whole-body condition, funding studies that explore how gluten exposure affects brain function, cognition, and emotional health.
PHILADELPHIA (October 30, 2025) – Beyond Celiac, the leading nonprofit catalyst for a cure for celiac disease, is advancing groundbreaking research into the gut–brain connection—revealing that gluten exposure can affect not only digestion but also brain function, cognition, and emotional health.
Long seen as a gastrointestinal condition, celiac disease is increasingly understood as a systemic autoimmune disorder with wide-reaching effects throughout the body. New research supported by Beyond Celiac is illuminating how gluten triggers changes in the brain that can cause fatigue, brain fog, anxiety, depression, and even problems with coordination and balance.
“We’re reframing celiac disease as more than a gut issue—it’s a whole-body condition that affects how people think, feel, and function,” said Debra Silberg, MD, PhD, Chief Scientific Officer, Beyond Celiac. “Recognizing this connection is essential to improving diagnosis, management, and ultimately treatment and a cure.”
Advancing Brain Research in Celiac Disease
Through a three-year Established Investigator Grant to the University of Sheffield (UK), Beyond Celiac is funding MRI-based studies that map how gluten exposure impacts brain structure and function. The results of an earlier study at Sheffield also funded by Beyond Celiac were recently published, showing that gluten exposure is associated with a variety of poorer brain health outcomes for patients with severe gluten-related neurological problems. These studies focus on the transglutaminase 6 (TG6) antibody, a marker linked to neurological effects of gluten.
The University of Sheffield is a leading center for celiac disease research, particularly in understanding its neurological effects through studies of brain damage and the role of the TG6 antibody. The university’s Sheffield Institute of Gluten-Related Diseases (SIGReD) conducts advanced research using tools like MRI to show how gluten affects the brain in patients with celiac and.
“Brain MRIs (magnetic resonance imaging) show a faster rate of brain atrophy, or the loss of brain cells and connections linked to the level of TG6,” said Iain Croall, PhD, University of Sheffield when speaking previously at a Beyond Celiac Research Summit regarding a 2020 study. “This is exciting because while there are a handful of studies that showcase this, this is the first time brain imaging is giving us tangible evidence that this is happening, allowing researchers to study the extent and pattern of white matter damage in the brain due to gluten exposure.”
Bridging Research and Patient Experience
Beyond Celiac’s own research echoes these findings. Data from its Go Beyond Celiac patient registry and Burden of Disease surveys show that neurological and psychological symptoms are widespread:
- 86% of participants reported brain fog or difficulty concentrating after gluten exposure
- 71% experienced headaches or migraines
- Many also reported anxiety, depression, and fatigue
These patient-reported experiences were further validated by new Beyond Celiac research presented at the 2025 American Academy of Neurology (AAN) Annual Meeting, which demonstrated that the majority of people with celiac disease experience cognitive and neurological symptoms—including brain fog, fatigue, headaches, anxiety, depression, and even ataxia—following gluten exposure. Together, these data sets provide a clearer picture of how gluten impacts the brain and underscore the importance of recognizing celiac disease as a systemic autoimmune disorder rather than a condition confined to the gut.
Toward a Future Beyond Celiac
The only current treatment for celiac disease is strict lifelong adherence to a gluten-free diet, which not only improves gut health but has also been shown to alleviate many neurological and cognitive symptoms over time.
This growing body of research reinforces the need for increased awareness, early testing, and multidisciplinary care in the management of celiac disease, as well as more research into the long-term effects of gluten-induced neuroinflammation and potential treatment approaches.
“Recognizing the gut–brain connection in celiac disease is crucial,” added Debra Silberg, MD, PhD, Beyond Celiac chief scientific officer. “Healthcare providers must consider a holistic approach when evaluating unexplained neurological or psychological symptoms, particularly when accompanied by subtle digestive complaints or a family history of autoimmune disease.”
