Migraine is a common condition in mitochondrial diseases, with a higher prevalence than in the general population. Although several clinical studies support the hypothesis that mitochondrial dysfunction plays a central role in the pathophysiology of migraine, currently there are few data in the literature regarding the efficacy and safety of drugs for the treatment and prophylaxis for this condition in patients with primary mitochondrial disorders. We report a 37-year-old woman affected by mitochondrial disease with progressive external ophthalmoplegia phenotype (PEO) associated with POLG mutation effectively treated with erenumab, in the absence of side effects. Monoclonal antibodies against the calcitonin gene-related peptide (CGRP) or against its receptor are innovative and specific therapies for migraine prophylaxis. This class of drugs is particularly suitable for subjects, such as those suffering from genetically determined mitochondrial dysfunction, in which pharmacological management can represent a challenge due to the nature of these neurogenetic disorders and/or the frequently associated comorbidities.
