Mal de debarquement.
MAIN OUTCOME MEASURE: Clinical features of mal de debarquement syndrome. RESULTS: Nearly all respondents were middle-aged women (26 of 27; mean age, 49.3 years). The duration of symptoms ranged from 6 months to 10 years (mean, 3.5 years; SD, 2.5 years). The symptoms were constant in 23 (85%) patients. Neither meclizine hydrochloride nor transdermal scopolamine was helpful. Benzodiazepines were of the most benefit. Balance rehabilitation physical therapy was undertaken by 15 patients, who on average reported a small benefit. CONCLUSIONS: More than double the number of previously reported cases of mal de debarquement syndrome were identified by this study. The syndrome usually occurs in middle-aged women following an ocean cruise. Symptoms are often refractory to vestibular suppressants as well as physical therapy.
