INSTITUTO MEXICANO DEL SEGURO SOCIAL UNIDAD DE INVESTIGACIÓN MÉDICA EN OTONEUROLOGÍA
Head and founder of the Otoneurology Research Unit at Instituto Mexicano del Seguro Social and Senior Lecturer at Universidad Nacional Autónoma de México (UNAM) in México city; previously she was Professor of Audiology and Otoneurology at UNAM. After completing her medical studies at the same Institutions, she was trained in Otoneurology at Linkoping University, in Sweden, and she was a research fellow in Neuro-otology at the MRC Human Movement and Balance Unit in London, UK. Then she got her master and doctorate degrees in Medical Sciences in México (UNAM) while continuing research collaboration in London.

Abstract

Abstract Body

Behaviour in the environment requires continuous updating of the internal representation of the body and the surroundings of the body. Altered perceptions of the self or the environment include depersonalization/derealization (DD) symptoms, which occur on a continuum from healthy to pathological states. A sensory mismatch may elicit erroneous perceptions of the body in the physical space. Consistently, sensory deficiencies can provoke discrepancies between the multi-sensory frame given by experience and the actual perception, accompanied by dizziness, unsteadiness and distress. Conversely, DD symptoms have also been related to Impairment of the capacity to regulate emotions, with an increased risk of cognitive and psychiatric comorbidity in patients with vestibular disease.

Vestibular signals contribute to the perception of the body and its interactions with the environment. In healthy subjects, artificial vestibular stimulation of the semicircular canals or the otoliths can induce DD symptoms. In vestibular patients, DD symptoms are more frequent and more severe when the clinical recovery is deficient, and they correlate with erroneous updating orientation in space. Furthermore, DD symptoms reported by patients with phantom limb pain may decrease after asymmetric vestibular stimulation (either of the horizontal semicircular canals or the utricles), which may provide an update of the immediate experience of the body. These effects can be accompanied by symptoms related to the sensory conflict and may modulate higher neural processes, with influence from individual factors. Further studies are needed to comprehend the vestibular contribution to cognitive and emotional processes.
