Impact of Vertigoheel® on Patients Suffering From Bilateral Vestibulopathy and Functional Dizziness

Study Overview
=================
Brief Summary
-----------------
In this study the researcher observe how vertigo symptoms change during two months of treatment with the natural medicinal product Vertigoheel©. Adult patients suffering from vertigo symptoms can participate if they are diagnosed with bilateral vestibulopathy (BVP) or functional dizziness (FD) and assigned to Vertigoheel treatment. Participating patients receive an examination at study start and after 2 months of Vertigoheel treatment. The study focuses on patient reported outcomes assessed by questionnaires. Vertigo symptoms are assessed by the Dizziness Handicap Inventory questionnaire. Patients' quality of life is assessed by a questionnaire. Body sway is assessed by static posturography. FD patients are additionally tested for depressive and anxiety symptoms by questionnaires. BVP patients are additionally tested for vestibular function by video head impulse test and caloric testing. Adverse events and other observations related to safety (physical examination and vital signs) are evaluated. Vertigo is a common symptom with significant adverse effects on patients' quality of life. Regardless of the exact cause of vertigo attacks, it is important to reduce the frequency, intensity, and duration of vertigo attacks with an effective medication that has no or minimal adverse effect. Vertigoheel®, a natural medicinal product consisting of four ponderable active ingredients, is approved in Germany as treatment for vertigo of various origins. However, no systematic data are available for Vertigoheel® regarding patient-reported outcomes in BVP and FD as the most accepted endpoint in vertigo studies.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Dizziness handicap inventory | Change from baseline in dizziness handicap inventory (DHI) after 2±1 months Vertigoheel® treatment. The DHI has a range from 0 to 100, the higher the score the worse. | 2 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Quality of life (QoL) | Change from baseline in quality of life (QoL) assessed by EQ-5D-5L after 2±1 months Vertigoheel® treatment | 2 months | 
| Postural imbalance | Change from baseline in body sway assessed by static posturography after 2±1 months Vertigoheel® treatment | 2 months | 
| Depressive symptoms in functional dizziness | Change from baseline in depressive symptoms of functional dizziness patients assessed by PHQ-9 questionnaires after 2±1 months Vertigoheel® treatment. The PHQ-9 has a range from 0 to 27, the higher the score the worse. | 2 months | 
| Anxiety symptoms in functional dizziness | Change from baseline in anxiety symptoms of functional dizziness patients assessed by GAD-7 questionnaires after 2±1 months Vertigoheel® treatment. The GAD-7 has a range from 0 to 21, the higher the score the worse. | 2 months |
