Rocking dizziness and headache: a two-way street.
Cephalalgia : An International Journal of Headache 2013 October
BACKGROUND: Chronic rocking dizziness, often described as the feeling of being on a boat, is classically triggered by prolonged exposure to passive motion. Patients with this motion-triggered sensation of rocking, which is also known as MAL DE DEBARQUEMENT SYNDROME , often develop new onset headaches along with the dizziness. Chronic rocking dizziness has also been noted in vestibular migraine, occurring without a motion trigger. We sought to clarify the association between both motion-triggered (MT) and non-motion-triggered (non-MT) chronic rocking dizziness and headache history.
METHODS: Our methods included questionnaire and interview study of subjects with either MT or non-MT chronic rocking dizziness.
RESULTS: Onset of headaches was earlier in patients with non-MT rocking dizziness (median 26 years: MT; 16 years: non-MT). In MT subjects, there was a bimodal peak of age of onset of headache (20-29 years and 40-49 years). Most headache met criteria for migraine in both groups. By the time that chronic dizziness occurred, both groups had a comparable prevalence of migraine headache (41%: MT; 46%: non-MT). Pre-existing headache usually worsened after the onset of dizziness.
DISCUSSION: Though rocking dizziness does not meet current criteria for vestibular migraine, migraine physiology may predispose to, develop in, or worsen with the onset of chronic rocking dizziness.
