The clinical and demographic features of dizziness related to general health among the Saudi population.

[Purpose] The purpose of this study was to determine the validity, demographic features of the newly developed Amer Dizziness Diagnostic Scale (ADDS), provide differential diagnosis of the vestibular disorders, assist in the clinical research and practice activities of health workers as well as to understand the probability of the utilization of the ADDS as a first-line evaluation tool in general clinical practice. [Subjects and Methods] Two hundred subjects of various ages including both male and female patients with a history of vertigo and/or dizziness were included in the study and evaluated once using the ADDS. [Results] There were more female (59.5%) than male (49.5) patients in this study. Additionally, we found that most patients (64.4%) had a central mediated problem. In addition, the Amer Dizziness Diagnostic Scale has been found to have both a sensitivity and specificity of 96% that can adequately determine the possible diagnosis of vestibular disorders. [Conclusion] This study has demonstrated the validity of the ADDS scale, the predominance of female involvement related to supplementary medication, vitamin D deficiency, general lifestyle factors, and fluid retention, high sensitivity and specificity, provide differential diagnosis of vestibular disorders that could be used as a first-line evaluation tool in general clinics.
