Abstract

OBJECTIVES
Fall is a major cause of morbidity and mortality among older adults. Falls result from many various causes, and dizziness is important risk for falls, especially in the elderly. Research on the relationship between chronic dizziness and falls in elderly people has been rarely performed and these were no studies that analyzed the risk of falls according to subtypes of chronic dizziness.
METHODS
We conducted a prospective study of the association between subtypes of chronic dizziness and falls in the elderly between 65 to 75 years. We divided dizzy patients into 5 groups according to the results of symptom, vestibular and autonomic function test. Falls and new events (acute dizziness or other medical conditions) were checked monthly by telephone or out patient department follow-up for 6 months.
RESULTS
Thirty-four patients were enrolled and all completed follow-up for 6 months. Nine patients classified as the falling groups and 34 patients as nonfalling group. Whereas the frequencies of orthostatic hypotension (n=6, 67%) and vestibular dysfunction (n=1, 11%) were higher in fall group, psychogenic dizziness (n=12, 35%), and vestibular migraine (n=3, 9%) were more frequent in nonfall group.
CONCLUSIONS
The presence of dizziness in the elderly is a strong predictor of fall, especially orthostatic hypotension is an important predictor of fall. In order to lower the risk of falls in the elderly, an approach based on the cause of dizziness is needed.
