[Vascular headache. Changes in visual evoked potentials].

The authors examined visual evoked potentials using the method of the visual full field stimulation hemi-field, using a check-board patterned structural stimulus in 69 patients with the diagnosis of vascular headache. The peak latencies of the waves did not differ significantly in the group of patients with vascular cephalea, as compared with the control group; this applies to both ways of stimulation. The es amplitudes of waves (P1 = P100 and N2) were significantly higher in the group with vascular cephalea after stimulation by the visual field.

[Vascular headache: circulatory, hemorrheologic, electrophysiologic and psychological aspects].

The aim of the work was to analyze circulatory, rheological, electrophysiological and psychological characteristics of patients with vascular headache, mostly migraine and vasomotor cephalea. The group was formed by 69 patients, mean age 40.4 +/- 9.
