Migraine is the second most disabling disorder across all age groups worldwide. Since 2018, two classes of drugs that inhibit the actions of calcitonin gene-related peptide (CGRP), which is implicated in migraine pathophysiology, have become available: gepants (CGRP receptor antagonists) and monoclonal antibodies directed against CGRP or its receptor. Despite phase 3 clinical trials and some real world evidence, knowledge of the pharmacology and related clinical effects of these drugs is low, and trial data are not necessarily generalisable to all populations. ⋯ If studies confirm this possibility, these characteristics could assist clinicians in choosing the optimal treatment for patients with migraine. The choice between a gepant or monoclonal antibody should be made carefully, taking into consideration a patient's comorbidities and preferences. As more becomes known about CGRP-targeted therapies, management based on the characteristics of patients could have a more prominent role in the treatment of migraine.

Atherosclerosis leading to stenosis of the internal carotid artery is the underlying cause of 8-15% of ischaemic strokes (symptomatic carotid stenosis). 1-2% of the adult population have asymptomatic carotid stenosis. Clinical trials in patients with symptomatic carotid stenosis showed a higher procedural risk of non-disabling stroke with stenting versus endarterectomy, but a higher risk of myocardial infarction, cranial nerve palsy, and access site haematoma with endarterectomy. ⋯ With advances in medical therapy against atherosclerosis, benefit from invasive therapy has become uncertain. Risk modelling, with the inclusion of brain and carotid plaque imaging, will become increasingly important in selecting patients for interventions.
