Background: Vertigo is an illusory sense of motion in the absence of real movement, either in the self or the environment. Vertigo is isolated and has no positive indications of dysfunction of the central neurological system. Study aims at studying MRI, TCD and BAEP relationships and alterations in individuals with isolated vertigo. Methods: Patient control research involves 50 patients with isolated vertigo, 50 matched age and gender health controls, from Al-Azhar University Hospitals, Assuit, Egypt, neurology and audio vestibular hospitals, from May 2019 through to June 2021. Results: patient start age with vertigo (40-60), disease duration (2-3) years, 70% with peripheral vertigo,30% with central vertigo, 86% with abnormal and 70% with abnormal BAEP and 74% with vertigo with an abnormal TCD. Relationship and variations in cervical MRI, TCD and BAEP in 50 patients with "isolated" vertigo and 50 healthy controls respectively were examined. Results: A statistically significant differences between the two groups were found for total TCD, BAEP abnormalities and no significant differences between the two groups in cervical MRI abnormalities. The findings revealed strong associations between TCD and cervical MRI, TCD and BAEP in the vertigo group. And TCD PI analysis and certain BAEP items revealed positive linear relationships. In the control group, there were no statistical differences or relationships. Conclusions: TCD is a "isolated" vertigo screening sensitive technique. A combined cervical MRI, TCD and BAEP test regimen is suited to evaluate the "isolated" vertigo.
