Vestibular System in Schizophrenia
Study Description
“Reactivity of the Vestibular System to Caloric Vestibular Stimulation in Schizophrenia”
This study aims to determine if individuals with schizophrenia have greater reactivity to vestibular stimulation than healthy controls. The physiological response of vestibular stimulation will be assessed with electronystagmography, which provides a measure of the intensity of the nystagmus via PSPV. Positive results would suggest greater vestibular system reactivity to vestibular stimulation may be a biomarker of schizophrenia. Pathophysiologically, increased vestibular reactivity to vestibular stimulation may reflect abnormal vestibular function or impaired central suppression of the vestibular ocular reflex.

Methods
No pharmaceutical medication involved
Patients and healthy individuals accepted
Procedure - Left body temperature VS
Caloric vestibular stimulation (CVS), which involves the irrigation of cold or warm water into the external ear canal, induces a temperature gradient across the semicircular canals of the vestibular apparatus stimulating the vestibular nerve. It is commonly used in both otolaryngology to assess vestibular function and neurology to test brain stem function
Procedure - Right body temperature VS
Caloric vestibular stimulation (CVS), which involves the irrigation of cold or warm water into the external ear canal, induces a temperature gradient across the semicircular canals of the vestibular apparatus stimulating the vestibular nerve. It is commonly used in both otolaryngology to assess vestibular function and neurology to test brain stem function
