“…Otoliths are structures composed of a gelatinous matrix combined with calcium carbonate, which is found in the endolymphatic viscous fluid of the saccule and utricle of the inner ear. The inertia experienced by otolith organs stimulates hair cells and their afferent nerves during head movements (7,32,34). The low frequency (0.1-3.5 Hz) (35) horizontal and vertical linear accelerations induced during earthquakes are detected by the vestibular organs, especially the otolith.…”

“…The low frequency (0.1-3.5 Hz) (35) horizontal and vertical linear accelerations induced during earthquakes are detected by the vestibular organs, especially the otolith. Besides, the prevalence of BPPV has been shown to increase after major earthquakes (7,32) and otolith dysfunction is considered a possible underlying mechanism (36,37). Furthermore, frequent physical shaking may directly impair the vestibular system.…”

“…Major earthquakes are associated with an increased prevalence of psychiatric morbidities (1,2), sleep disorders (3,4), and dizziness (5)(6)(7). The Kumamoto earthquakes, which occurred on April 14 and 16, 2016, (moment magnitude = 9.0) and included several high-magnitude vibrations and aftershocks without secondary disasters, led to reportedly significant outbreaks of dizziness over a large area surrounding the earthquake epicenter several months after the initial earthquake.…”

“…Although several reports have described post-earthquake dizziness (5)(6)(7), the characteristic symptoms of dizziness remain undefined. After the Tohoku earthquake on March 11, 2011 (moment magnitude = 9.0) and its sequelae (a tsunami and the Fukushima nuclear disaster), Nomura et al defined the characteristic symptoms of post-earthquake dizziness as post-earthquake dizziness syndrome (PEDS) (9).…”

This retrospective chart review aimed to examine both the vestibular function and causes of dizziness experienced by individuals following a series of major earthquakes and repetitive aftershocks. All patients with balance disorders who experienced the 2016 Kumamoto earthquakes and their aftershocks completed questionnaires relevant to balance disorders and were enrolled in this study after providing informed consent. There were 2.8 times more patients with balance disorders post the earthquake. Anxiety (P = 0.02), orthostatic dysregulation (P = 0.005), and motion sickness scores (P = 0.03) were all significantly higher after the earthquakes. A subset of participants underwent clinical equilibrium testing, showing significant deteriorations in the equilibrium test results (stabilometry: P = 0.01), cervical vestibular-evoked myogenic potentials (P = 0.04), and head-up tilt (P = 0.03) after the earthquake. The findings of this study also suggest that earthquake-induced disequilibrium may be further influenced by physical stressors, including sensory disruptions induced by earthquake vibrations, changes in the living conditions, and autonomic stress. This study increases our understanding of human equilibrium in response to natural disasters. Moreover, these findings will facilitate the management of dizziness experienced during or after such disasters. Future studies should identify strategies for mitigating autonomic dysfunction to prevent post-earthquake dizziness.

Change in and Long-Term Investigation of Neuro-Otologic Disorders in Disaster-Stricken Fukushima Prefecture: Retrospective Cohort Study before and after the Great East Japan Earthquake

et al. 2015

On March 11, 2011, Japan’s northeast Pacific coast was hit by a gigantic earthquake and subsequent tsunami. Soma City in Fukushima Prefecture is situated approximately 44 km north of Fukushima Daiichi Nuclear Power Plant. Soma General Hospital is the only hospital in Soma City that provides full-time otolaryngological medical care. We investigated the changes in new patients from one year before to three years after the disaster. We investigated 18,167 new patients treated at our department during the four years from April 1, 2010 to March 31, 2014. Of the new patients, we categorized the diagnoses into Meniere’s disease, acute low-tone sensorineural hearing loss, vertigo, sudden deafness, tinnitus, and facial palsy as neuro-otologic symptoms. We also investigated the changes in the numbers of patients whom we examined at that time concerning other otolaryngological disorders, including epistaxis, infectious diseases of the laryngopharynx, and allergic rhinitis. The total number of new patients did not change remarkably on a year-to-year basis. Conversely, cases of vertigo, Meniere’s disease, and acute low-tone sensorineural hearing loss increased in number immediately after the disaster, reaching a plateau in the second year and slightly decreasing in the third year. Specifically, 4.8% of patients suffering from these neuro-otologic diseases had complications from depression and other mental diseases. With regard to new patients in our department, there was no apparent increase in the number of patients suffering from diseases other than neuro-otologic diseases, including epistaxis, and allergic rhinitis. Patients suffering from vertigo and/or dizziness increased during the first few years after the disaster. These results are attributed to the continuing stress and tension of the inhabitants. This investigation of those living in the disaster area highlights the need for long-term support.
