Abstract
Benign convulsions with mild gastroenteritis (CwG) are characterized by afebrile convulsions associated with viral gastroenteritis in previously healthy infants and children. The main causative pathogens are rotavirus and norovirus. CwG occurs frequently in both East Asian and Western countries. The prevalence of CwG was reportedly not decreased by the introduction of rotavirus vaccines, and the prevalence of norovirus-associated CwG has been increasing annually. Convulsions in CwG are usually clustered, do not last longer than 5 minutes, and are mostly generalized. Laboratory diagnostics, electroencephalography (EEG), and imaging findings are usually normal. There is a probability of mild, transient abnormal findings on EEG or imaging limited to the acute disease phase. Although several reports have suggested that pathogens that affect the central nervous system through direct or indirect mechanisms could be related to the pathophysiology of CwG, its mechanism is not fully understood. Several antiepileptic drugs are effective during convulsions; however, long-term antiepileptic treatment is not required as CwG usually has a good prognosis.
