Quantitative EEG in children with headache.

The object of this work is to determine if Brain Mapping can reveal significant differences between a normal control group and a group whose members suffer from one of three types of headache: tension-type, migraine with aura and migraine without aura. Both groups were formed by children aged between 6 and 14; the latter were undergoing no treatment and were in a headache-free phase. Results demonstrate that there are no significant differences between the control group and the tension-type headache group. Neither were differences found in migraine without aura group but in migraine with aura there was an increase of the theta/alpha ratio in the temporal posterior and occipital zones. This ratio could be used as a neurophysiological indicator in the evolution of the migraine with aura pathology.
