The association of dizziness and headache is quite frequent and it has been known for a long time. The visual and auditory evoked potentials and EEG had already shown a damage of CNS in migrainous. The vestibular tests with ENG, which is enclosed in the routine study of the patients of the Headache Centre of Modena University (Italy), has shown a high percentage of alterations in different tests. Out of crisis a decrease of VOR and troubles of OKN and pursuit are noted. During crisis the reflectivity increases above all in the same part of the pain and a further alteration of smooth pursuit is observed. The Nomiphensine test suggest that these alterations of CNS are caused by changes in biochemistry of CNS, above all in the monoamines.
