Active clinical trials for "Vertigo"

Surgical removal of vestibular schwannoma causes acute vestibular symptoms, including postoperative vertigo and oscilopsia due to nystagmus. In general, the dominant symptom postoperatively is vertigo. Preoperative chemical vestibular ablation can reduce vestibular symptoms postoperatively.

Dizziness is one of the most common complaints among patients admitted to the emergency department (ED). In most cases, the etiology remains unclear. Dizziness has a broad differential diagnosis. The initial symptoms of ALD can include many general complaints. Aim of this study is to investigate whether SOD is a symptom of ALD, the necessity of liver function tests for patients with SOD in the ED, and a cost analysis of liver function tests.

BPPV is a benign condition of the balance organ, localized in the inner ear, in which calcium crystals loosen up and move freely in the endolymphatic fluid of the inner ear (more specifically in the semi-circular canals). During certain posture changes or head movements, these moving calcium crystals cause dizziness and balance problems. The general objective of the study is to evaluate the impact of BPPV on the balance of older adults in nursing homes. For this purpose, we will compare the balance of residents with BPPV with residents without BPPV. Furthermore, we will identify the impact of treatment on balance problems and fall risk in older adults in nursing homes.

Patients with dizziness presently undergo physical therapy rehabilitation. Our study will study whether Wii Balance Board made by Nintendo Inc. will be helpful in patients with dizziness. They will undergo dizziness evaluation to quantify their dizziness.

This study evaluate the diagnostic accuracy of a simplified clinical algorithm (STANDING) for the differential diagnosis of acute vertigo in the emergency department. In particular, the investigators want to analyze the sensitivity and specificity of the test for the diagnosis of vertigo of central origin and the reproducibility of the test. In suspected central vertigo of ischemic origin, a duplex sonography to identify vertebral artery pathology will be performed.

This study will be carried out prospectively on patients who applied to the cardiovascular surgery polyclinic and the carotid-vertebral artery doppler ultrasound due to the vascular problem. All patients will fill "Balance Disorder Scan Survey" and "Vertigo-Dizziness Imbalance Questionnaire-SS". Patients who score 1 and more are directed to the ear nose throat polyclinic and detailed differential diagnosis. Those who score 0 will be in control group.

No studies have explored how patients with chronic dizziness react to a diagnosis of Persistent Postural Perceptual Dizziness (3PD) and their beliefs and representations of the diagnostic label. Investigating the experience of diagnostic labelling from the perspective of patients will allow clinicians to recognise whether this is a helpful term to adopt and ways to improve the clinical consultation. This is a qualitative study that will consist of semi-structured interviews with people with a new diagnosis of 3PD. The main objective of the study is to explore how patients react to this diagnostic label, what they understand about their diagnosis and how their own meanings affect their expectations and illness perceptions. Between 12-15 patients will be recruited from the balance clinic at Guy's Hospital, London, UK. The qualitative data will be analysed using thematic analysis which will draw on pragmatic interpretive descriptive methodology.

The vestibular system in the inner year is an important system in the body which is responsible for balance. In addition, there is evidence that the vestibular system plays a role in maintaining blood pressure while changing body position, such as moving from lying down in bed to sitting. Dysfunction of the vestibular system may affect the ability to maintain blood pressure, therefore the aim of this study is to assess if a specific problem in the vestibular system (Benign Paroxysmal Positional Vertigo- BPPV) may cause changes in the interaction between the vestibular system and the cardiovascular system. We assume that patients with this medical condition (BPPV) will have different heart rate parameters in comparison with healthy patients.

The primary aim of this study is to determine whether the prevalence of neuroticism, anxiety and body vigilance is higher in patients diagnosed with PPPD compared to those who suffered a vestibular insult but did not develop PPPD and healthy controls. An increased prevalence of one or more of these factors may identify them as risk factors in the development of PPPD. The secondary aim is to understand how PPPD affects quality of life.

This study aimed to investigate whether there is a relationship between nystagmus intensity and vestibular-ocular reflex gains by comparing Videonystagmography and video head impulse test in patients with posterior semicircular canal-benign paroxysmal positional vertigo.
