Psychological, behavioural, or physical therapies for migraine have been shown to be effective in treating the symptoms of migraine.[Campbell et al., 2000; Lee et al., 2019] Moreover, some patients may prefer nonpharmacological treatment – such preference may result from having not responded in the past to pharmacotherapy, or the presence of some coexisting or comorbid condition that makes certain pharmacotherapy unsuitable.[Campbell et al., 2000]
