Migräne - Bewährtes und aktuelle Entwicklungen

Abstract

Migraine is a very common primary headache disorder associated with intermittent attacks and great suffering. Despite extensive research efforts in the recent years, many pathophysiological aspects remain unclear. An altered cortical adaptability and the brainstem as a migraine generator are probably involved in the initiation of a (silent) cortical spreading depression and other processes that lead to neurogenic inflammation of the meninges causing the headache. Numerous studies in the last years have examined somatic, especially cerebrovascular and also psychological comorbidities. For attack therapy, CGRP antagonists have emerged as promising non-vasoconstrictive acting alternatives for triptans. However, they were so far not approved due to liver enzyme elevations in safety studies. Another new approach without vasoconstrictive action are the selective 5-HT1F agonists (especially Lasmiditan). Large placebo-controlled and triptan-controlled trials need to be awaited. For migraine prophylaxis, a comparable effect of sports and pharmacological prophylaxis using topiramate could be found. Particularly the combination of drug and non-drug therapies (such as the combination of stress management training with a beta-blocker treatment) achieves high efficacy. Also interdisciplinary, multimodal treatment approaches are important options. Two large multicentre studies have demonstrated the efficacy of botulinum toxin A as a prophylactic treatment for chronic migraine. Neuromodulative and neurostimulative procedures are promising but still experimental treatment options for patients with refractory migraine.
