“…[2][3][4][5] There are several reasons for this controversy. Much of the earlier work focused on physiological responses to laboratory stressors 6,7 and not on the experience of naturally occurring stress. More recent studies have measured daily life stress over the past week or month and found that subjects diagnosed with TTH reported more stressful events at a greater magnitude than controls without headache.…”

Childhood Headache, Stress in Adolescence, and Primary Headache in Young Adulthood: A Longitudinal Cohort Study

Childhood headaches are related to the appraisal of life events reported during mid adolescence. Childhood headaches also appear to confer a specific risk for the development of combined headache. There was little evidence for a prospective relation between stress in mid adolescence and tension-type headache in young adulthood, supporting claims that proximal (rather than distal) stress is associated with this disorder.

“…1 It is frequently characterized by the presence of electromyographic changes and/or "tender points" in the pericranium and the neck muscles. 2 Chronic migraine is characterized by an increasing frequency of migraine attacks until the headache becomes daily, albeit varying in intensity. 3 In fact, violent migraine attacks are often superimposed on a basis of chronic headache.…”

Alteration of Central Excitation Circuits in Chronic Headache and Analgesic Misuse

1997

Central excitatory circuits could be involved in the pathophysiology of pain; particularly, the genesis of chronic pain. The "second pain" is the sensation that follows the initial pain after an appropriate nociceptive stimulus. The second pain is amplified by repeating the stimulus after brief intervals (temporal summation). This phenomenon is the psychophysical correlate of the excitatory pain circuits. The temporal summation of the second pain was evaluated in four groups of subjects; one group affected by migraine without aura, one by episodic tension headache, one by chronic daily headache, and a group of healthy subjects. A percutaneous electrical shock was used as the nociceptive stimulus. The intensity of the second pain was significantly greater in the group of patients with chronic headache in comparison with the other groups. The patients with chronic headache were subdivided into three groups on the basis of their clinical history: a group with transformed migraine; a group with chronic headache ab initio, a form related to the first one; (both groups suffered from chronic daily headache with a frequent superimposition of episodes of migraine attacks) and the third group consisted of patients with chronic tension headache. The temporal summation of the second pain was altered in the first two groups. The patients with chronic migraine abused ergotamine given as a symptomatic drug. Those who were able to discontinue this drug were retested and reported a decrease of the second pain in comparison to the previous measurements. The results of the present study indicate that central excitatory circuits could be involved in the mechanism leading to the development of chronic daily headache.

“…Two studies that have examined sex differences among individuals with headache have found that in response to stress the reactions of men and women differ physiologically from one another. 5,14 Although no evidence was presented directly in support of perceptual or appraisal differences, the existence of sex differences in stress appraisal remains a possibility. We did not identify a large enough sample of men with headache to include in the present study and compare for gender effects.…”

“…Given that those with headache differ from headache‐free participants in their appraisals of everyday stressors (ie, rating them as more stressful than do headache‐free participants), one might expect headache participants to rate laboratory stressors as more stressful than do controls. However, patients with tension‐type headache and controls do not differ in their subjective ratings of stress in the laboratory when ratings are made during or immediately following laboratory stressors 12,14,15 . Headache participants may report higher levels of stress before stressful laboratory tasks than do the controls.…”

Tension‐type Headache and Stressful Events: The Role of Selective Memory in the Reporting of Stressors

This study examined evidence for the role of selective memory for stressful events in women with headache. Previous studies have reported that on retrospective measures of stress, those with tension-type headache report more stressful events and rate the events as more stressful than did headache-free controls. However, when ratings are made concurrently, participants with headache and controls did not differ in their ratings of equivalent stressors presented in the laboratory. One theory for why differences are found in stress ratings made retrospectively, but not concurrently, is that selective memory biases recollection of past events in patients with headache. This study compared self-report ratings of stressful events and their perceived impact made either concurrently or retrospectively to determine if selective memory might explain the discrepancies found in earlier studies. Participants included 20 patients with tension-type headache and 22 headache-free controls. Participants were compared on hourly, daily, and weekly measures of stressors and their perceived impact via hourly and nightly visual analog scale ratings, the Daily Stress Inventory, and the Weekly Stress Inventory. If support was to be offered to the hypothesis that selective memory biases the retrospective memory of patients with headache, then an interaction between group assignment (ie, headache versus control group) and time of rating would be expected. No such interaction occurred. Results from the study suggest that all participants have a tendency to overestimate stress on retrospective measures, but that patients with headache do not do so at a significantly different rate than do headache-free controls. The alternative hypothesis that patients with headache tend to appraise everyday events as more stressful is supported.
