The visual evoked response(VERs)to both flash and pattern stimulation were recorded in 44 children with migraine,with or without aura,and 8 with periodic syndrome.The controls were 50 age and sex matched children.VERs of 50 sex matched adults with migraine were also recorded.The fast wave amplitude in children with migraine was higher than that in controls.The amplitude was higher in younger children with migraine(under 13 years)than that in older children or adults with migraine.Children with periodic syndrome had VERs similar to those of children with migraine.The VER, especially in children,may prove to be a useful test in the diagnosis of migraine. |
