| Summary: | 20% of world population suffers from dizziness. The low sensitivity of the most common vestibular tests makes their results questionable. Diagnostic methods for dizziness are compared. Four vestibular projections (cortical, motor, autonomic, and limbic) are considered. The cortical projection is assessed by evoked potentials (the sensitivity and specificity of the method are 90.57 and 98.57%, respectively). Examination of vestibular motor reactions is based on the tests of Romberg, Fukuda, and Uemura. Posturography and recording the movements of the center of mass at rest in the Romberg position (their sensitivity is 35 to 54%) are popular. In the same patients, the sensitivity of the tests of Fukuda and Uemura is as high as 98.15%. The caloric test is the gold standard for vestibular diagnosis; its sensitivity is 70% and its specificity is 90%. These of rotation tests are 33.5 and 92.5%, respectively. Methods for study of vestibular autonomic and limbic reactions are under development. Tests having a sensitivity of > 90% are proposed to be introduced into clinical practice. |
