This report summarizes the most recent government statistics on the prevalence and burden of migraine and severe headache in the US civilian and active duty military populations. The prevalence of migraine headaches is high, affecting roughly 1 out of every 7 Americans annually, and has remained relatively stable over the last 8 years. Migraine and headache are leading causes of outpatient and ED visits and remain an important public health problem, particularly among women during their reproductive years.
estimates of the prevalence and burden of migraine and chronic migraine. Objective.-To gather in one place and compare the most current available estimates of the US adult prevalence of headache and migraine, and the number of affected people overall and in various subgroups, and to provide estimates of headache burden and treatment patterns by examining migraine and headache as a reason for ambulatory care and emergency department (ED) visits in the United States.Methods.-We reviewed published analyses from available epidemiological studies identified through searches of PubMed and the National Center for Health Statistics. We aimed to identify information about migraine and headache burden, and treatment in national surveys conducted over the last decade. For each source, we selected the best available and most current estimate of migraine or headache prevalence, and selected associated measures of disability, health care use, and treatment patterns.Results.-Compared with a slightly higher proportion of 22.7% in the National Health and Nutrition Examination Survey, 16.6% of adults 18 or older reported having migraine or other severe headaches in the last 3 months in the 2011 National Health Interview Survey. In contrast, the AMPP study found an overall prevalence of migraine of 11.7% and probable migraine of 4.5%, for a total of 16.2%. Data from National Ambulatory Medical Care Survey/National Hospital Ambulatory Medical Care Survey showed that head pain was the fifth leading cause of ED visits overall in the US and accounted for 1.2% of outpatient visits. The burden of headache was highest in females 18-44, where the 3-month prevalence of migraine or severe headache was 26.1% and head pain was the third leading cause of ED visits. The prevalence and burden of headache was substantial even in the least affected subgroup of males 75 or older, where 4.6% reported experiencing severe headache or migraine in the previous 3 months. Triptans accounted for almost 80% of antimigraine analgesics prescribed at office visits in 2009, nearly half of which were for sumatriptan. Migraine is associated with increased risk for other physical and psychiatric comorbidities, and this risk increases with headache frequency.
The objective of this study was to evaluate the time-series relationships between stress, sleep duration, and headache pain among patients with chronic headaches. Sleep and stress have long been recognized as potential triggers of episodic headache (< 15 headache days/month), though prospective evidence is inconsistent and absent in patients diagnosed with chronic headaches (≥ 15 days/month). We reanalyzed data from a 28-day observational study of chronic migraine (n = 33) and chronic tension-type headache (n = 22) sufferers. Patients completed the Daily Stress Inventory and recorded headache and sleep variables using a daily sleep/headache diary. Stress ratings, duration of previous nights' sleep, and headache severity were modeled using a series of linear mixed models with random effects to account for individual differences in observed associations. Models were displayed using contour plots. Two consecutive days of either high stress or low sleep were strongly predictive of headache, whereas two days of low stress or adequate sleep were protective. When patterns of stress or sleep were divergent across days, headache risk was increased only when the earlier day was characterized by high stress or poor sleep. As predicted, headache activity in the combined model was highest when high stress and low sleep occurred concurrently during the prior 2 days denoting an additive effect. Future research is needed to expand on current findings among chronic headache patients and to develop individualized models that account for multiple simultaneous influences of headache trigger factors.
Objective To quantitatively synthesize extant literature on perceived triggers of primary headache disorders. Methods A meta-analytic review of headache trigger survey studies was conducted. Endorsement rates, assessment method, and headache and sample characteristics were extracted from included articles. Separate random-effects models were used to assess trigger endorsement rates and post-hoc meta-regressions examined potential moderator variables. Results 85 articles from 1958 to 2015 were included, involving 27,122 participants and querying 420 unique triggers (collapsed into 15 categories). Four-fifths (0.81; 95% CI .75 to .86) of individuals with migraine or tension-type headache endorsed at least one trigger. Rates increased with the number of categories queried (OR: 1.18, 1.08-1.30) and year of publication (OR: 1.04, 1.00-1.08). The triggers most commonly endorsed were stress (.58, .53-.63) and sleep (.41, .36-.47). Conclusions Extreme heterogeneity characterizes the headache trigger literature. Most individuals with a primary headache disorder perceive their attacks to be triggered by one or more precipitants, the most common of which are stress and sleep. However, trigger endorsement is influenced by method of assessment. Enhancing methodological consistency and prioritizing experimental studies would improve our understanding of headache triggers.
Although most individuals with recurrent headache disorders in the general population do not experience severe psychopathology, population-based studies and clinical investigations find high rates of comorbidity between headache and mood and anxiety disorders. When present, psychiatric disorders may complicate headache treatment and portend a poorer treatment response. The negative prognosis associated with psychiatric comorbidity emphasizes the importance of the identification of psychopathology among those with headache beginning at an early age, and suggests that the treatment of psychiatric comorbidity is warranted to improve the outcome of headache management.In this article we describe the mood and anxiety disorders most commonly associated with migraine, tensiontype headache, and chronic daily headache. We provide recommendations for the assessment of comorbid mood and anxiety disorders as well as a brief overview of treatment options. Last, we discuss the clinical implications of mood and anxiety disorders on the treatment and outcome of headache.
Migraine is often comorbid with psychiatric disorders such as major depression, bipolar disorder, and anxiety disorders. Although most of the research on psychiatric comorbidities and migraine is of an epidemiologic nature, a growing body of literature has investigated possible mechanisms underlying this relationship, such as medication overuse, serotonergic dysfunction, ovarian hormone fluctuations, and central sensitization. The present article overviews this growing literature and notes strategies for the clinical management of migraine patients with psychiatric comorbidities.
Psychiatric comorbidity, especially depression and anxiety, has been well documented in patients with primary headache disorders. The presence of psychiatric comorbidity in headache patients is associated with decreased quality-of-life, poorer prognosis, chronification of disease, poorer response to treatment, and increased medical costs. Despite the prevalence and impact, screening for psychiatric disorders in headache patients is not systematically performed, either clinically or in research studies, and there are no guidelines to suggest which patients should be screened or in what manner. We review a variety of screening methods and instruments, focusing primarily on self-report measures and those available in the public domain. Informal verbal screening may be sufficient in a primary care setting, but should include screening for both anxiety and depression. Explicit screening for anxiety is important, as anxiety may have a more significant impact on headache than does depression and may occur in the absence of clinical depression. Formal screening with instruments that can identify a variety of psychiatric disorders is appropriate for patients with daily headache syndromes, patients who are refractory to usual care, and patients referred for specialty evaluation. Limitations of screening instruments include the influence of transdiagnostic symptoms and the need for confirmatory diagnostic interview. The following instruments appear most suitable for use in headache patients: for depression,
Episodic migraine is associated with negative impact in numerous domains among university students. These findings replicate and extend those of studies on other samples and have implications for future research studies with this population.
