- Background
The dopam ine m etabolism is believed to play an important part in the pathophysiology of migraines. It was reported that the distribution of alleles for the dopamine D4 receptor gene (DRD4) in migraine w ithout aura patients is significantly different from those in control group. A polymorphism of the D RD4 m ight be related to genetic suscep- tibility of m igraine. The aim of this study w as to investigate the association of DRD4 exon III polymorphism between patient group w ith m igraine and control group.
Methods
This study compared 150 patients with m igraine (38 m ales, 112 females and m ean age 42.4±10.23) 100 healthy control subjects (25 males, 75 females and mean age 42.6±10.35) in order to determine the association between a polymorphism of the DRD4 exon III and m igraine. Using PCR techniques, the DRD4 polymorphism was denoted by 48-base-pair tandem repeat in exon III of the gene.
Results
There w as no significant difference between the healthy controls, m igraine without aura patients and m igraine with aura patients in age and sex distribution. Significant differences w ere noted in the genotype betw een m igraine without aura group and m igraine w ith aura group. Also significant differences w ere observed in allele frequencies compared m igraine w ithout patients w ith control group and m igraine w ith aura patients.
Conclusions
The DRD4 polymorphism appears to be involved in the genetic predisposition to m igraine w ithout aura. Migraine w ithout aura m ay have different pathophysiology from m igraine w ith aura in genetic field. Korean Journal of Headache 7(1):41-45, 2006

- Background
Migraine is a common, disabling illness and imposes great burden on society. Migraine- related disability is often poorly communicated between patients and physicians. The prevalence, disability and medical service utilization behavior of migraine has not been evaluated sufficiently in Korea. The goal of this study is to determine the proportion of migraine among patients presented with headache in neurology clinic and to assess the level of headache related disability of patients.
Methods
This survey recruited patients who consulted to neurologists with a chief complaint of headache in 17 hospitals in Korea. Patients answered a self-administered questionnaire. The investigators independently responded another questionnaire about their patients' headache and assessed headache related disabilities after diagnostic interview. Patients suffering from headache ≥15 days per month were excluded.
Results
Among 570 patients (female 433 (76.0%), mean age 47.8±15.6) who responded adequately the questionnaire, 376 patients had migraine. Fifty-eight percent of the migraine patients were newly diagnosed as having migraine through this survey. However, 74.9% of migraineurs have taken pain-relieving drugs when headache developed; 12.3% of the migraineurs overused the medications. One hundred forty one (37.5%) migraineurs reported that they miss family, social and leisure activities because of headache. Thirty percents of migraineurs were on prophylactic medications and 14.4% of them have visited emergency room due to severe headache. The neurologists would recommend prophylactic medication in 64.3% of patients who were not on prophylaxis.
Conclusions
This study showed that migraine is the most common headache syndrome in the neu- rology clinics of Korea. Significant portion of the migraine patients have migraine-related disability. A majority of migraineurs exposed pain-relieving drugs without exact diagnosis and some of them overused them. Korean Journal of Headache 6(2):121-128, 2005
