What neurological symptoms are associated with Celiac disease in children and adults?

Celiac disease is not just a gut condition. It can also affect the nervous system, leading to a range of neurological symptoms. These symptoms can occur in both children and adults, sometimes even without typical digestive issues. The most common neurological problems include problems with coordination (ataxia), nerve damage (neuropathy), seizures, headaches, trouble thinking clearly, and sleep problems. A gluten-free diet may help improve some of these symptoms, but not always completely.

What the research says

A narrative review of neuropsychiatric manifestations in celiac disease found that neurological features include cerebellar ataxia (loss of coordination), peripheral neuropathy (nerve damage causing numbness or tingling), epilepsy, headache, cognitive dysfunction (brain fog), and sleep disorders ¹. These symptoms can appear in both children and adults, though the review notes differences between the two populations ¹. The exact causes are not fully understood, but possible mechanisms include autoimmune reactions, inflammation, and nutrient deficiencies ¹.

Another review on systemic consequences of celiac disease confirms that neurological issues are among the best-studied systemic effects ⁹. It notes that early diagnosis and treatment with a gluten-free diet appear to be beneficial for most, but not all, of these neurological conditions ⁹. This means that while a gluten-free diet can help, some people may continue to have symptoms.

In children, the neurological symptoms can be particularly concerning. A pilot study on an online parent intervention for children with celiac disease (ages 8-11) highlighted that the condition creates psychosocial challenges, which can affect a child's quality of life ⁷. While this study focused on quality of life, it underscores that neurological and psychological symptoms are important to address in pediatric celiac disease.

It is important to note that neurological symptoms can also occur in people with Down syndrome, who have a higher risk of celiac disease ¹⁰. In this population, autoimmune neurologic conditions are more common, and celiac disease should be considered if neurological symptoms appear ¹⁰.

What to ask your doctor

• Could my (or my child's) neurological symptoms be related to celiac disease, even if there are no digestive issues?
• What tests are available to check for celiac disease if I have neurological symptoms?
• If I have celiac disease and neurological symptoms, how strictly do I need to follow a gluten-free diet to see improvement?
• Are there any specialists, like a neurologist or dietitian, I should see to help manage neurological symptoms related to celiac disease?
• What other conditions could cause similar neurological symptoms, and how can we tell them apart from celiac-related issues?
