Assessing Neurocognitive Effects of Gluten Exposure

Stopped early · Not applicable · Has a placebo group

Conditions studied: Celiac Disease, Neurobehavioral Manifestations

In brief

Many patients with celiac disease complain of neurocognitive symptoms such as mental confusion, grogginess, difficulty with concentration and forgetfulness after exposure to gluten. However, there is little data on any possible association between impaired cognitive function and gluten intake in celiac disease. The investigators predict that patients with celiac disease, when exposed to gluten, will experience neurocognitive symptoms such as confusion, forgetfulness and difficulty concentrating. The goals of this study are to determine the prevalence of neurocognitive symptoms after exposure to gluten in patients with celiac disease and to characterize the nature of these symptoms both in terms of their duration and severity.
