Often there is sense of fullness that increases in the ears, followed by the attack, which may last for hours. Some people are so affected that they cannot stand up. Often, as time progresses, hearing loss becomes significant. The episodes may continue for years. The syndrome is thought to be the result of an increase in the fluid in the inner ear, known as the endolymphatic fluid.
Aspirin use can also produce tinnitus and vertigo.
The central vestibular system includes the vestibular nerve, which transmits information from the inner ear, and the brain, which receives this information and processes it. If vertigo occurs secondary to stroke, it is almost always not an isolated finding. This diagnosis should be strongly considered in anyone with risk factors for stroke. Brain Tumors Tumors that occur in the brainstem or in the cerebellum or adjacent to it, can cause vertigo as a primary symptom. Some of these tumors are accompanied by early hearing loss.
