Dizziness and vertigo in patients with tension-type headache: A case-control study.

BACKGROUND

A few studies have demonstrated dizziness and vertigo in patients with tension-type headache (TTH). However, the prevalence and other characteristics of vestibular symptoms in TTH has not been studied in a systemic manner so far. The aim of the study was to see the prevalence of vestibular symptoms in patients with tension-type headache as compared with controls.

METHODS

This case-control study included 100 TTH patients and 100 controls who do not have significant history of headaches.

RESULTS

Vestibular symptoms (Vertigo, dizziness, vestibulovisual or postural symptom) were experienced by 25% of patients with TTH and 10% in the control group (Odd Ratio = 3.0 [95% CI, 1.4-6.6], P = .006). The vestibular symptoms were statistically more in patients with chronic tension-type headache (CTTH) than episodic TTH (67% vs 9%. 9, P5 =  < 0.005). Hospital Anxiety and Depression score (HAD-A and HAD-D) scores in patients with TTH with vestibular symptoms were significantly higher than TTH without vestibular symptoms- HAD-A (5.1 ± 1.7 vs 4.0 ± 1.5, P = 0.002) and HAD-D(5.8 ± 2.1 vs 4.2 ± 1.9, P =  < 0.001). Phonophobia was also more frequent in TTH patients with vertigo (42% vs.13%, P5 = 0.005).

CONCLUSION

Vestibular symptoms may be more common in patients TTH than control. The prevalence of vestibular symptoms depends on the frequency of TTH.
