Vertigo is defined as a condition of dizziness of feeling of spinning, or swaying when one is stationary. Dizziness is a general, non-specific term to indicate a sense of disorientation. Some researchers suggested that vertigo
is a subtype of dizziness and refers to an erroneous perception of
self- or object-motion or an unpleasant distortion of static
gravitational orientation that is a result of a mismatch between
vestibular, visual, and somatosensory systems, affecting
approximately 20-30% of the general population(1) and about two to three times higher in women than in men.
Risk Factors
1. Endolymphatic hydrops
In the study to assess the results of treatment for a first episode of benign paroxysmal positional vertigo (BPPV) and risk factors for recurrence at the Kobe University Graduate School of Medicine, showed that endolymphatic hydrops is a risk factor for recurrence of BPPV and that prevention of recurrent BPPV is important for control of endolymphatic hydrops(10)
2. Vascular risk factors
Vascular risk factors
predispose to vertebrobasilar ischemia. Cervical osteophytes can
impinge on the vertebral artery causing mechanical occlusion during head
turning. Presentation with vertigo in such instances is a common finding(11)
3. Otitis media history
Researchers found that having an otitis media history or eustachian tube dysfunction
determined with the nine-step inflation/deflation tympanometric test
before diving, or difficulty in clearing ears during diving could be
important risk factors for AV in sport SCUBA divers (p <.05)(12).
4. Gender
If you are women, you at two to three times higher risk to develop Vertigo
5. Vestibular neuritis (VN) is a condition of an ear disorder that involves irritation and inflammation. The recurrence rate of vertigo due to any cause in patients with vestibular neuritis (VN) was about 26.0(13)
6. Heredity
Genetic loci and clinical features of familial episodic ataxias have
been defined in linkage disequilibrium studies with mutations in
neuronal genes KCNA1 and CACNA1A. Migrainous vertigo
is a clinical disorder with a high comorbidity within families much
more common in females with overlapping features with episodic ataxia
and migraine. Bilateral vestibular hypofunction is a heterogeneous
clinical group defined by episodes of vertigo leading to progressive loss of vestibular function which also can include migraine. Meniere's disease is a clinical syndrome characterized by spontaneous episodes of recurrent vertigo, sensorineural hearing loss, tinnitus and aural fullness and familial Meniere's disease in around 10-20% of cases.(14)
