Summary

Suffering from dizzy spells and migraine headaches?

Vestibular Migraine (VM), a newly recognized type of migraine that causes bouts of dizziness.

University of California, Los Angeles (UCLA) and The Mayo Clinic is seeking people with VM to participate in a research study. The purpose of this study is to look at the natural history of VM and learn more about common symptoms. Investigators also want to learn the effects, both positive and negative, of the commonly used migraine drug, rizatriptan, when it is used for spells of dizziness in people with VM.

• Patients have a history of vestibular migraine

• Patients are able to maintain a vestibular symptom diary

The study includes 3 visits with compensation. All participants must complete questionnaires on dizziness, headache symptoms, general health and well-being, mental health, and a questionnaire on patient's satisfaction with study medication.
