Most people think of gluten-related disorders as digestive problems, but in rare cases, gluten can also affect the brain. Gluten ataxia is a serious autoimmune condition where the body’s immune response to gluten damages the cerebellum — the part of the brain responsible for balance, coordination, and movement.
Though rare, gluten ataxia can be progressive and irreversible if left untreated. Early diagnosis and strict gluten-free eating are crucial.
What Is Gluten Ataxia?
Gluten ataxia is a neurological autoimmune disorder triggered by the ingestion of gluten. The immune system produces antibodies that cross-react with brain tissue, specifically targeting the cerebellum.
Over time, this can lead to:
- Loss of coordination (ataxia)
- Unsteady gait
- Slurred speech
- Difficulty with fine motor skills (e.g. writing, buttoning clothes)
- Vision problems or dizziness
These symptoms may be subtle at first but can worsen without intervention.
How Is It Diagnosed?
Diagnosis can be challenging. There’s no single test for gluten ataxia, and it is often misdiagnosed as other neurological disorders.
A thorough diagnostic process may include:
- Neurological exam
- MRI of the brain (to detect cerebellar damage)
- Blood tests for gluten-related antibodies, including anti-gliadin and transglutaminase 6 (TG6)
- Ruling out other causes of ataxia (e.g. vitamin deficiencies, stroke, multiple sclerosis)
Many patients with gluten ataxia do not have digestive symptoms or test positive for celiac disease, which makes it easy to miss.
Treatment: The Gluten-Free Diet
The only known treatment for gluten ataxia is a strict lifelong gluten-free diet. Unlike gluten sensitivity, even tiny amounts of gluten can continue damaging the brain in people with gluten ataxia.
Early dietary intervention can:
- Halt disease progression
- Improve coordination in some cases
- Prevent further neurological damage
The longer the condition goes undiagnosed, the lower the chance of reversing symptoms.
Who Is at Risk?
Gluten ataxia can affect both adults and children, but it is more commonly diagnosed in middle-aged adults. People with:
- A family history of celiac disease
- Other autoimmune disorders
- Neurological symptoms with unknown cause
…may benefit from screening if symptoms suggest possible ataxia.
Final Thoughts
Gluten ataxia is a reminder that gluten-related disorders aren’t just about the gut. If you or a loved one has unexplained coordination issues, especially with a family history of autoimmunity, consider speaking to a neurologist familiar with gluten ataxia.
