Active clinical trials for "Dizziness"

Obstructive Sleep Apnea may cause dizziness or vertigo through hypoxia of the vestibular nuclei in the brain. Treating sleep apnea may improve dizziness or vertigo.

This is an observational longitudinal study to investigate if negative illness perceptions predict less improvement in dizziness handicap following vestibular rehabilitation. Consecutive patients (n=260) who enter the vestibular rehabilitation programme at Guy's Hospital, London will be included. Questionnaires will be conducted immediately before, and after their final treatment. The main outcome will be the Dizziness Handicap Inventory after rehabilitation.

Do migrainous vertigo patients have more pathology in their vestibular system than migraine patients without vertigo? The aim of this study is to compare the vestibular system of migraine patients with and without vertigo in the symptom-free period by vestibular function tests, videonystagmography, vestibular evoked myogenic potentials, and subjective visual vertical.

The score on the Dizziness Handicap Inventory (short version) before and after hearing aid fitting and usage will be compared

Patients hospitalized at the rehabilitation department at the hospital will fill a questionnaire regarding dizziness and ear diseases, and the Dizziness Handicap Inventory, and then will be examined by an ENT physician, followed by a video Head Impulse Test (vHIT) study.
