[|AI|]  Hi, Dizziness is one of the most common reasons adults visit their neurologist or general doctor. Since tilt table test was positive and EEG negative your daughter may have a condition that causes an abnormal change in blood pressure, heart rate or heart rhythm. If I were your doctor I would first do a thorough physical exam. I would ask for a brain MRI scans to rule out serious conditions. I would order an ECG and Echocardiogram for the heart. I would also ask for blood count test to rule out anemia as it is common in young females to have anemia which could manifest itself with similar symptoms such as light headdress. Treatment depends on underlying cause. Take care. Hope I have answered your question. Let me know if I can assist you further.
