TOPOGRAPHIC MAPPING OF BRAIN ELECTRICAL-ACTIVITY IN CHILDREN WITH FOOD-INDUCED ATTENTION-DEFICIT HYPERKINETIC DISORDER

In 15 children suffering from food induced attention deficit hyperkine tic syndrome, topographic EEG mapping of brain electrical activity was carried out following avoidance and ingestion of previously identifie d provoking foods. A crossover design was used and recordings were int erpreted independently by two investigators, one of whom was blind to the order of testing. During consumption of provoking foods there was a significant increase in betal activity in the frontotemporal areas o f the brain. This investigation is the first one to show an associatio n between brain electrical activity and intake of provoking foods in c hildren with food-induced attention deficit hyperactivity disorder. Co nclusion These data support the hypothesis that in a subgroup of child ren with attention deficit hyperactivity disorder certain foods may no t only influence clinical symptoms but may also alter brain electrical activity.
