A touchy subject: an assessment of cutaneous allodynia in a chronic migraine population

چکیده
BACKGROUND Cutaneous allodynia (CA) is a common feature of migraine, which has a complex underlying pathophysiology that is not well understood. In addition to pain, photophobia, phonophobia, osmophobia, nausea, and vomiting, CA can contribute to the overall disability caused by migraine. The presence of CA can be established via a validated questionnaire. Validated questionnaires and other tests are rarely performed in clinical practice. As such, current prevalence estimates for CA may be an underestimation. METHODS Utilizing a validated questionnaire, we assessed the presence of CA in consecutive patients (n=44) presenting with chronic migraine at a tertiary headache center. RESULTS CA appears to be quite prevalent, at ~90%, among female patients with chronic migraine. CONCLUSION CA prevalence in chronic migraine may be underestimated in the literature, and larger studies may better demonstrate a more accurate estimate of its prevalence.

Identifying cutaneous allodynia in chronic migraine using a practical clinical method.
Cutaneous allodynia is common in migraine. In the majority of previous studies on allodynia in migraine, only patients with episodic migraine (EM) were included. Little is known on patterns of allodynia in chronic migraine (CM). Since the presence of allodynia is associated with a poor response to triptans, a clinically practical method to test migraine patients for allodynia would be useful to...
متن کاملCutaneous allodynia is more frequent in chronic migraine, and its presence and severity seems to be more associated with the duration of the disease.
Objective To evaluate cutaneous allodynia among patients with chronic and episodic migraine in a tertiary headache clinic. Methods 80 subjects with episodic migraine and 80 with chronic migraine were assessed in a tertiary hospital. The 12-item Allodynia Symptom Checklist/Brazil questionnaire was applied to classify subjects according to the presence and severity of cutaneous allodynia. Res...
متن کاملReferred cutaneous allodynia in a migraine patient without simultaneous headache.
Cutaneous allodynia has been described in migraine. We report on a 39-year-old woman with migraine with aura who had cutaneous allodynia to both dynamic (brush) and static (pressure) mechanical stimulation between attacks. For both sensory modalities, the evoked pain on allodynia testing was located to the right frontal area (the location of her usual migraine headache), contralaterally to the ...
متن کاملAn association between migraine and cutaneous allodynia.
Recent animal studies on the mechanism of migraine show that intracranial pain is accompanied by increased periorbital skin sensitivity. These findings suggest that the pathophysiology of migraine involves not only irritation of meningeal perivascular pain fibers but also a transient increase in the responsiveness (ie, sensitization) of central pain neurons that process information arising from...
متن کاملCutaneous allodynia as a predictor of migraine chronification.
Cutaneous allodynia is a common feature accompanying migraine attacks and considered a clinical marker for central sensitization. In a longitudinal study, we wanted to investigate if allodynia in migraine patients is a predictor of increasing frequency of migraine days. We included 3029 well-defined, web-based migraine patients (86% female, mean age 42.8 ± 11.4 years, 61% migraine without aura)...
