Purpose: Headaches children are sometimes associated with dizziness, and complain of very severe pain and sometimes may be intractable to the usual headache treatments. So it is very necessary for accurate diagnosis and proper treatment. Materials and Methods: the 17 pediatric patients with headache and/or dizziness were enrolled from July 2012 to August 2013. The patients were divided into two groups; the migraine group (MG) and the dizziness without headache group (DG). All patients were carried out autonomic nerve function and head-up tilt test (HUT). The two groups were compared by non-parametric statistics. Results: In total of 17 people, the male to female ratio was 1:4.7 and mean age 13.4±2.9 years. At the nine patiets in MG, symtoms or signs of dizziness were orthostatic causes in 5 (55.6 %), transient visual changes in 4 (44.4%), cold sweats in 4 (44.4 %), general fatigues in 4 (44.4%), and transiet tachycardia in 2 (22.2 %) in order.  After HUT, three patients were compatible to the orthostatic intolerance (OI), and one was postural orthostatic tachycardia syndrome (POTS) in 9 migraine patiets, but two was OI, one was POTS, and the others was vasovagal causes.  At HUT the heart rate (HR) increased 16±15 (beats/min) in DG and 19.0±12.9 (beats/min) in MG, which was significantly increased than in DG. The effects of fluorocortisone treatment showed improvement in 6 patients (66.6%) with migraine, and in 4 (100%) with dizziness. Conclusions: The Head-up tilt test is important for the accurate diagnosis and proper treatment in migraine patients with dizziness
