Among all those reported, confirmed neuropsychiatric manifestations of celiac disease are loss of short-term memory, anxiety and depression, psychosis, ataxia, seizures, irritability, and chronic headache (29). Neurogastroenterology covers primarily diseases of the intrinsic enteric nervous system, "brain of the gut," which is a part of the nervous system and controls motility, endocrine secretions, and microcirculation of the gastrointestinal system.
