What does the evidence show? Efficacy of behavioural treatments for recurrent headaches in adults.

Behavioural treatments (predominantly biofeedback, relaxation and cognitive-behavioural) have been utilised in headache management for nearly 4 decades. This paper examines their clinical efficacy, drawing upon 2 primary sources of evidence: meta-analytic and evidenced-based reviews. Behavioural treatments have demonstrated efficacy and have been endorsed by various reviewing groups, such as the US Headache Consortium. Outcomes from behavioural treatments appear to endure over longer-term follow-up intervals as well. Meta-analyses comparing behavioural and pharmacological treatments have revealed similar levels of outcome. The article closes with a brief discussion of methods investigators are exploring to make behavioural treatments more available and affordable to headache patients.
