Autonomic Symptoms and Allodynia in Migraine

Frequency of cranial autonomic symptoms (cas) in migraine patients

An 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...

Migrainous corpalgia: body pain and allodynia associated with migraine attacks.

Cephalic and extracephalic allodynia are recognized as a common sign of sensory sensitization during migraine episodes. However, the occurrence of body pain in migraine has not been thoroughly explored. Here we report three patients presenting with spontaneous body pain in association with migraine attacks. A 41-year-old woman experienced face and limb pain along with migraine headaches; it sta...

Is phonophobia associated with cutaneous allodynia in migraine?

OBJECTIVE To determine whether phonophobia and dynamic mechanical (brush) allodynia are associated in episodic migraine (EM). METHODS Adult patients with EM were prospectively recruited. A structured questionnaire was used to obtain demographic and migraine related data. Phonophobia was tested quantitatively using a real time sound processor and psychoacoustic software. Sound stimuli were pur...

Referred 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 ...
