Active clinical trials for "Headache Disorders, Secondary"

According to the definition from International Headache Society, medication overuse headache (MOH) is diagnosed when patients takes painkillers for more than 10 or 15 days per month (depending on what kind of painkillers being used), for more than 3 months, which results in the deterioration of headache. The treatments of MOH include preventive medication of headache and withdrawal of the overused painkillers. Other than the simple oral advice, some researchers recommended non-pharmacological methods. Pryse-Phillips et al. (1998) reviewed the the treatment of migraine and suggested that biofeedback, relaxation, cognitive behavior therapy (CBT), psychological therapy, hypnosis and physical treatment are effective. Researches also point out CBT is effective on withdrawing medication in patients with MOH (Kroner-Herwig, 2009). Lake (2006) reported that behavioural therapy maybe an adjunct therapy to preventive medication to reduce the relapse rate of medication overuse. The purpose of this study is to confirm the effect of CBT in patients with MOH. The target is to reduce the frequency of headache and use of painkillers. Patients could benefit from the education and relaxation training during CBT to cope with headache and reduce the use of painkillers. The research will recruit 60 patients with MOH at Neurology Clinics, Far Eastern Memorial Hospital. They will be separated into two groups, 30 in control group and the other 30 in the experimental group. Education of MOH, relaxation and cognitive restructuring would be included in the four weeks training program. The training program is under the supervision of a neurologist from Far Eastern Memorial Hospital and a psychology professor from Fu Jen Catholic University. The control group will accept four weeks telephone interview to confirm their headache diary including the frequency of headache and use of painkillers. The frequency of headache and medication use will be used for analyzing the effect of CBT.

The purpose of this study is to determine if ibudilast is effective in reverting patients with medication overuse headache suffering chronic daily headache back to their original episodic headache pattern.

Medication Overuse Headache (MOH) is an illness affecting about 1,5 % of the general population. It is characterized by chronic headache occurring for at least 15 days a month, by a use of antimigraine drugs during at least 3 months for more than 10 days a month (for ergots, triptans, opiate derivates and combined analgesics) or for more than 15 days a month (for simple analgesics). The chronic headache must have occurred during the period of antimigraine drug abuse and the headache must have returned to its episodical pattern after withdrawal of antimigraine drugs. But, about 50% of the MOH patients will relapse during the first year following the antimigraine drugs withdrawal. The pathophysiology of MOH is still largely unknown, and the role of antimigraine drug abuse in the transformation from migraine through MOH is not fully understood.

From 1 January 2004 to 31 December 2006 64 individuals with probable medication overuse headache were included in a randomized, 1-year open-labeled, multicentre study to evaluate the effect of early introduction of prophylactic treatment compared to abrupt withdrawal and with a control group (ClinicalTrials.gov number NCT00159588). In this follow-up, randomized patients still alive 4 years after primary inclusion time will be invited to a follow up interview, evaluating the headache complaints and the proportion of recurrent medication overuse.

The project will be conducted to investigate the hormonal homeostasis in men and women, with a special emphasis on sex hormones in men and AMH level in women, before and after withdrawal of the overused analgesics among MOH patients. Additionally, a more broad endocrine profile will be explored before and after withdrawal. It is hypothesized that patients with MOH have disturbed hormone levels, which is normalized after withdrawal of the medication-overuse.

The purpose of this study is to assess the benefits of almotriptan used as a transitional therapy and topiramate in subjects with medication overuse headaches (MOH.

This study uses a single questionnaire to evaluate two separate primary outcomes: To identify association between chronic headache in women who have given birth to children as compared to a control group of women who have raised children but have not given birth to them To identify association between chronic back pain in women who have given birth to children as compared to a control group of women who have raised children but have not given birth to them

Medication overuse headache (MOH) is a disabling and costly disorder which is characterized by chronic headache and overuse of different headache medications. Patients with MOH are more likely to coexist with affective disorders such as anxiety and depression, and are more likely to suffer from sleep disturbances than those with episodic headache. Melatonin is a hormone secreted from the pineal gland. Melatonin is an antioxidant, antinociceptive, hypnotic, anticonvulsant, neuroprotective, anxiolytic, sedative and analgesic. This observational study aims to investigate clinical characteristics of patients with MOH and to explore the relationship between the serum melatonin level and medication overuse headache. Researchers hope to provide a new idea for the clinical treatment of MOH: melatonin can be used as an adjuvant therapy for MOH in the future.
