Evaluation of BPPV with vertebral artery values

Figures & data

Table 1 Atherosclerotic risk factors of BPPV patients

Atherosclerotic risk factors	Percentage
Hypertension	13 (26%)
Hyperlipidemia	11 (22%)
Smoking	13 (26%)
Diabetes mellitus	10 (20%)
Thyroid dysfunction	10 (20%)a

Note:

a Thyroid dysfunction in 10 patients includes 3 with hyperthyroidism and 7 with hypothyroidism.

Abbreviation: BPPV, benign paroxysmal positional vertigo.
