Dignosis of migraine is only based on the medical history, and objective methods to aid the clinical diagnosisare absent. Although transcranial Doppler ultrasonography (TCD) abnormalities in headache-free migraineurs have been reported previously, diagnostic criteria for migraine is still lacking and this may limit the practical application of TCD for migraine. We prospectively studied several abnormal TCD indices in interictal migraineurs and their sensitivity and specificity to define the optimal diagnostic criteria. Young (20 yrs$age=29.0{\pm}6.1yrs$) were compared to 69 controls (M:F=25:44, Mean $age=31.2{\pm}5.5yrs$). Elevated MFV (> 2SD)was observed in 63% of migraineurs while n 12% of control (p<0.01). High AI (>25%) or high HI (>3.0) was present in 17% of migraineurs, while 3% and none in controls (p<0.01). Sensitivity of elevated MFV, high AI, and high HI was 63%, 17%, 17% and specificity was 88%, 97%, 100%, respectively. If all these indices were combined, sensitivity and specificity reached 69% and 86%. These preliminary results suggest pathophysiological implication of vasospasm in interictal migraineurs, and TCD may be practically applicable for migraine. Optimal diagnostic criteria and therapeutic options for patients with abnormal TCD findings remain to bo determined.

The aim of study was to evaluated the possible role of cranial artery velocity in headache pathogenesis. The present study was studied of five headache(F=5. Mean $age=29.80\pm6.76yrs$) were compared to 4 controls(F=4, Mean $age=29.00\pm5.48yrs$). Transcranial doppler ultrasonography(TCD) is a new non-invasive and easily applicable method to evaluate flow velocities of the intracranial and extracranial cerebral arteries. TCD was performed with standard method to measure the mean Flow Velocity(MFV) of the middle and posterior cerebral arteries, the internal carotid artery, the vertebral and the basilar artery. We reviewed the whole TCD results performed at Taejon Veterans Hospital from October. 11. 2000 to November. 10. 2000. Mean flow velocities in headaches and controls at their 6 decades are $28.00\pm3.61cm/sec$ and $41.25pm1.71cm/sec$ in lent PCA (P<0.01), $50,000\pm23.07cm/sec$ and $82.75\pm15.59cm/sec$ in right MCA(P<0.05), $26.20\pm4.82cm/sec$ and $45.50\pm4.51cm/sec$ in fight PCA(P<0.01). $26.60\pm4.56cm/sec$ and $38.25\pm4.92cm/sec$ in right VAC(P<0.01). After treatment for 2 weeks, mean of velocity on pre treatment and post treatment and post treatment are $28.00\pm3.61cm/sec$ and $38.20\pm5.81cm/sec$ in left PCA (P<0.05), $26.20\pm4.827cm/sec$ and $39.20\pm5.54cm/sec$ in right PCA(P<0.05), $40.60\pm9.18cm/sec$ in right VA(P<0.01). It is concluded that Electrical Therapy for two weeks was effected to promote Mean Flow of Velocity in cranial artery. Mean of velocity in cranial artery with headaches observed in this study was lower than controls, but MFV was promote after treatment for 2 weeks.
