Objective To evaluate the effectiveness of biofeedback in preventing chronic daily headaches. Methods One hundred patients experiencing daily headaches were randomly divided into a biofeedback group ( n=50) and a drug therapy group (n=50). The patients in the drug therapy groupwere administered a predetermined course of medication. Those in the biofeedback group were given 30 minutes of biofeedback therapy twice a week for 8 weeks, followed by 10 months of intensive therapy once a month. The headache frequency, duration of headache at-tacks, days of using acute pain medication and any other adverse events were recorded 3, 6 and 12 months after the treatment. Results The patients in the biofeedback group had significantly less-frequent headaches, shorter headache attacks and fewer days of using acute pain medications. Conclusion Compared to drug therapy, biofeed-back can prevent chronic daily headachesmore safely and effectively.

Objective To explore the personality characteristics of patients with chronic migraine complicating drugs overuse.Methods A total of 67 cases of migraine (control group) and 175 cases of medication overused migraine (MOH) were treated in the neurology department of this hospital from March to December 2016.The patients conformed to the migraine diagnostic criteria of the International Classification of Headache Disorders Third Edition (ICHD-3) formulated by the International Headache Society.The personality assessment adopted an internationally used Minnesota Personality Questionnaire.Results The scores of suspected disease,depression,rickets and social introgression in the observation group were higher than those in the control group,the difference was statistically significant (P＜0.05).In the observation group,there was a negative correlation between personality suspicion,rickets,neurasthenia,social introversion and education (P＜ 0.05).In the personality traits aspect of the observation group,hypochondriasis,hysteria,neuradynamia and social introversion were negatively correlated with the cultural degree (P＜0.05).Conclusion The personality changes in the four aspects of hypochondria,depression,hysteria and social introversion in the patients with MOH are more obvious than those in the patients with simple chronic migraine.
