簡易検査では異常のないめまい症例の診断

Vertigo is thought to be a symptom which generally is hard to understand. There is no problem when there are some abnormal findings in equilibrium function tests, represented by characteristic nystagmus and CP. When encountering vertigo cases with rare abnormal findings, a short-term attack of vertigo and few objective findings, there are many patients for whom considerable effort is made on diagnosis and explanation. We investigated clinically the treatment of vertigo cases which showed no abnormal findings.
The subjects were 21 patients who were treated in former ENT clinic as unknown vertigo or vestibular disorder. Vertigo cases are classified into peripheral vertigo, central vertigo, functional vertigo and other vertigo. Vertigo can be classified into those types of vertigo based on the pattern of vertigo attack. It is indispensable in the treatment of vertigo to confirm the existence of nystagmus with the positional and positioning nystagmus test by Frenzel glasses and infrared CCD camera. Though a flow chart type diagnosis index is useful for vertigo, we must recognize the existence of serious pitfalls in it. The precise diagnosis of vertigo is essential for effective treatment of vertigo. The "diagnosis study" for vertigo contributes to further development and establishment for patients who suffer from intense vertigo.
