Autonomic Nervous Function of Patients with Meniere's Disease

Abstract

To clarify the autonomic nervous function in patients with Meniere's disease, the following tests were carried out;
1. General autonomic nervous function tests,
1) Tone of the sympathetic nervous system,
2) Sensitivity of adrenergic receptors,
3) Sympathetic and parasym pathetic nervous activity,
4) Reflex functions of autonomic nervous syste m,
2. Local autonomic nervous function tests,
1) Ice water immersion test,
2) Ashner's test,
3) Forehead cooling test,
Many patients exhibited decreased parasympathetic nervous activity in any stage and laterality differences in cervical sympathetic nervous function in attack stage. So I considered that the decreased activity of parasympathetic nervous activity was predisposition and laterality differnces in cervical sympathetic nervous function was induced factor in Meniere's disease.
