Post Earthquake Equilibrium Disturbance: A Study After Nepal-India Earthquake 2015

Nepal and adjoining areas of India suffered a series of massive earthquakes in April-May 2015. This was followed by a remarkable increase in the patient presenting with vague dizziness like features which could not be attributed to any defined variant of vestibular disorder. Extensive search of literature revealed only scarce information about ambiguous post-earthquake vestibular symptoms and their management. We performed a detailed epidemiological analysis of these patients to analyse the presentation, underlying mechanism and optimal management. The results were scrutinised in light of existing international literature. We observed that earthquake precipitated a psychological stress like event that provoked features of disequilibrium and the neuroanatomical basis of the proposition was explored. We renounce the hypothesis of Secondary BPPV precipitated by earthquake leading to symptoms. The results were interpreted from the perspective of Indian scenario and its utility in post-earthquake disaster management in our country has been highlighted.
