A triciklusos antidepresszívumok helye a fejfájások kezelésében

The two most important representatives of the primary headaches are migraine and tension-type headache. More than 10% of the population suffer from migraine and even a greater part, approximately 30-40% from tension-type headache. These two headache types have a great effect both on the individual and on the society. There are two types of therapeutic approaches to headaches: the abortive and the prophylactic therapy. Prophylactic treatment is used for frequent and/or difficult-to-treat headache attacks. Although both migraine and tension-type headache are often associated with depression, for their treatment - in contrast to the widespread medical opinion - not all antidepressants were found to be effective. Amitriptyline, which is a tricyclic antidepressant, is used as a prophylactic therapy for headache since 1968. Its efficacy has been demonstrated in several double-blind, placebo-controlled studies. Although the newer types of antidepressant, such as selective serotonin reuptake inhibitors and selective serotonin-norepinephrine reuptake inhibitor, have a more favorable side-effect profile than tricyclic antidepressants, their headache prophylactic effect has not been proven yet

Increased activation of the pregenual anterior cingulate cortex to citalopram challenge in migraine: an fMRI study

Background: The anterior cingulate cortex (ACC) is a key structure of the pain processing network. Several structural and functional alterations of this brain area have been found in migraine. In addition, altered serotonergic neurotransmission has been repeatedly implicated in the pathophysiology of migraine, although the exact mechanism is not known. Thus, our aim was to investigate the relationship between acute increase of brain serotonin (5-HT) level and the activation changes of the ACC using pharmacological challenge MRI (phMRI) in migraine patients and healthy controls. Methods: Twenty-seven pain-free healthy controls and six migraine without aura patients participated in the study. All participant attended to two phMRI sessions during which intravenous citalopram, a selective serotonin reuptake inhibitor (SSRI), or placebo (normal saline) was administered. We used region of interest analysis of ACC to compere the citalopram evoked activation changes of this area between patients and healthy participants. Results: Significant difference in ACC activation was found between control and patient groups in the right pregenual ACC (pgACC) during and after citalopram infusion compared to placebo. The extracted time-series showed that pgACC activation increased in migraine patients compared to controls, especially in the first 8–10 min of citalopram infusion. Conclusions: Our results demonstrate that a small increase in 5-HT levels can lead to increased phMRI signal in the pregenual part of the ACC that is involved in processing emotional aspects of pain. This increased sensitivity of the pgACC to increased 5-HT in migraine may contribute to recurring headache attacks and increased stress-sensitivity in migraine

The validation of the Hungarian version of the ID-migraine questionnaire

Despite its high prevalence, migraine remains underdiagnosed and undertreated. ID-Migraine is a short, self-administrated questionnaire, originally developed in English by Lipton et al. and later validated in several languages. Our goal was to validate the Hungarian version of the ID-Migraine Questionnaire.Patients visiting two headache specialty services were enrolled. Diagnoses were made by headache specialists according to the ICHD-3beta diagnostic criteria. There were 309 clinically diagnosed migraineurs among the 380 patients. Among the 309 migraineurs, 190 patients had only migraine, and 119 patients had other headache beside migraine, namely: 111 patients had tension type headache, 3 patients had cluster headache, 4 patients had medication overuse headache and one patient had headache associated with sexual activity also. Among the 380 patients, 257 had only a single type headache whereas 123 patients had multiple types of headache. Test-retest reliability of the ID-Migraine Questionnaire was studied in 40 patients.The validity features of the Hungarian version of the ID-Migraine questionnaire were the following: sensitivity 0.95 (95% CI, 0.92-0.97), specificity 0.42 (95% CI, 0.31-0.55), positive predictive value 0.88 (95% CI, 0.84-0.91), negative predictive value 0.65 (95% CI, 0.5-0.78), missclassification error 0.15 (95% CI, 0.12-0.19). The kappa coefficient of the questionnaire was 0.77.The Hungarian version of the ID-Migraine Questionnaire had adequate sensitivity, positive predictive value and misclassification error, but a low specificity and somewhat low negative predictive value
