Gluten-induced Neurocognitive Impairment: Results of a Nationwide Study.

Goals: This study aimed to understand the neurocognitive symptoms associated with gluten exposure in individuals with self-reported celiac disease (CD) and nonceliac gluten sensitivity (NCGS).

Background: While gluten-induced neurocognitive impairment (GINI; eg, "celiac fog" or "brain fog") is commonly described by individuals with CD and NCGS, there are little data regarding the prevalence and symptoms associated with these experiences.

Study: A 9-question online survey was accessed by 1396 individuals (1143 with CD; 253 with NCGS).
