Abstract
SYNOPSIS
20 children with clinically diagnosed migraine were asked to wear
either a rose coloured tint or density matched blue tint for a period
of 4 months. The frequency, duration and intensity of migraine attacks
were recorded, together with the amount of visually provoked beta
activity in the EEG. After one month's wear all the children in the
study revealed an initial improvement in headache frequency. However,
only those children wearing rose tints sustained this improvement up to
4 months, when the mean headache frequency had improved from 6.2 per
month to 1.6 per month. The headache frequency of those children
wearing blue tints revealed no overall improvement after 4 months. The
improvements in headache frequency in children wearing rose tints
correlated with a reduction in visually provoked beta activity.
