The objective of this review is to provide an evidence-based discussion of different treatment strategies for medication-overuse headache (MOH). ⋯ Considering current available evidence and the systemic toxicity of overusing acute headache medication, we suggest discontinuation of the overused medication with the addition of preventive medication. Appropriately sized, randomized controlled trials evaluating the safety and long-term efficacy of preventive medication plus early discontinuation of overuse vs preventive medication alone vs early discontinuation of overuse alone are needed.

Review Meta Analysis
Vagally mediated heart rate variability in headache patients-a systematic review and meta-analysis.
Vagal nerve activity-indexed by heart rate variability (HRV)-has been linked to altered pain processing and inflammation, both of which may underpin headache disorders and lead to cardiovascular disease (CVD). Here we examined the evidence for differences in parasympathetic (vagal) activity indexed by time- and frequency-domain measures of HRV in patients with headache disorders compared to healthy controls (HCs). ⋯ vmHRV is reduced in patients with headache disorders, findings associated with a medium effect size. Suggestions for future research in this area are provided, emphasizing a need to investigate the impact of headache disorders and commonly comorbid conditions-including mental disorders-as well as the investigation of the risk for CVD in migraine in particular. We further emphasize the need for large-scale studies to investigate HRV as a mechanism mediating the association of migraine and CVD.

Migraine is a highly prevalent neurological disorders and a major individual and societal burden. Migraine is not curable at the present time, but it is amenable to acute symptomatic and preventive pharmacotherapies. ⋯ Although current knowledge on migraine pathophysiology suggests a central nervous system dysfunction, there is some evidence that interventions targeting peripheral nerves are able to modulate neuronal circuits involved in pain control and that they could be useful in some selected patients. Larger, well-designed and comparative trials are needed to appraise the respective advantages, disadvantages and indications of most interventions discussed here.
