The Identification and Characterization of Autonomic Dysfunction in Migraineurs With and Without Auras

This is a study to compare subject response and symptoms resulting from administration of three clinical assessments.

* The 3 assessments are

1. passive upright tilt table testing,
2. quantitative sudomotor axon reflex testing (QSART)and
3. punch biopsy.

The comparison of results will be from two subject groups:

• Group A, the migraine suffering patient with or without aura
• Group B, the migraine suffering patient with or without aura who has diagnosed orthostatic intolerance (i.e.,feeling dizzy or faint when making a body position change).
