Positional Vertigo Linked to Osteoporosis and Osteopenia

Lowest T scores are decreased in patients with the condition

THURSDAY, March 26 (HealthDay News) -- The dizziness-inducing condition known as benign positional vertigo is associated with osteopenia and osteoporosis, researchers report in the March 24 issue of Neurology.

S.-H. Jeong, M.D., of the Seoul National University College of Medicine in South Korea, and colleagues assembled 209 patients with benign positional vertigo and a control group of 202 people with no history of vertigo. Bone mineral densitometry was performed on the lumbar spine and femur to determine bone mineral density.

The researchers found that in both sexes, the lowest T scores were decreased in patients who had benign positional vertigo compared to those in the control group. The prevalence of osteopenia and osteoporosis was significantly higher in the benign positional vertigo cohort than in the control group. After adjustment for age, sex, alcohol, smoking and hyperphosphatemia, only the existence of osteopenia or osteoporosis was associated with an increased risk of benign positional vertigo (adjusted odds ratio of osteopenia, 2.0; adjusted odds ratio of osteoporosis, 3.1), the report indicates.

"Osteopenia/osteoporosis may be associated with idiopathic benign positional vertigo. The effectiveness of measuring bone mineral densitometry and restoring normal calcium metabolism for preventing recurrences of benign positional vertigo requires further validation," the authors write.
