In 1861 the French physician Prosper Ménière theorized that attacks of vertigo, ringing in the ear (tinnitus) and hearing loss came from the inner ear rather than from the brain, as was generally believed at the time. Once this idea was accepted, the name of Dr. Prosper Ménière began its long association with this inner ear disease and with inner ear balance disorders in general.

Endolymphatic hydrops is a disorder of the inner ear and can affect the endolymphatic fluid of the cochlea, the vestibular apparatus, or both. Although its underlying cause and natural history are unknown, it is believed to result from abnormalities in the quantity, composition, and/or pressure of the endolymph (the fluid within the endolymphatic sac, a compartment of the inner ear).
In a normal inner ear, the endolymph is maintained at a constant volume and with specific concentrations of sodium, potassium, chloride, and other electrolytes. This fluid bathes the sensory cells of the inner ear and allows them to function normally. In an inner ear affected by hydrops, these fluid-system controls are believed to be lost or damaged. This may cause the volume and concentration of the endolymph to fluctuate in response to changes in the body’s circulatory fluids and electrolytes.
Approximately 40% of migraine patients have some accompanying vestibular syndrome involving disruption in their balance and/or dizziness at one time or another, which is often more persistent and debilitating than the original headache.
Tinnitus is abnormal noise perceived in one or both ears or in the head. Tinnitus (pronounced either “TIN-uh-tus” or “tin-NY-tus”) may be intermittent, or it might appear as a constant or continuous sound. It can be experienced as a ringing, hissing, whistling, buzzing, or clicking sound and can vary in pitch from a low roar to a high squeal.

Third window syndrome: What it is and how it’s treated What is Third Window Syndrome? Third window syndrome describes a group of inner ear disorders that results from a leakage of pressure and/or fluid from
Benign Paroxysmal Positional Vertigo (or BPPV) is the most common cause of vertigo, which is a false sensation of spinning.
– Benign – it is not life-threatening
– Paroxysmal – it comes in sudden, brief spells
– Positional – it gets triggered by certain head positions or movements
– Vertigo – a false sense of rotational movement
BPPV is a mechanical problem in the inner ear. It occurs when some of the calcium carbonate crystals (otoconia) that are normally embedded in gel in the utricle become dislodged and migrate into one or more of the 3 fluid-filled semicircular canals, where they are not supposed to be. When enough of these particles accumulate in one of the canals they interfere with the normal fluid movement that these canals use to sense head motion, causing the inner ear to send false signals to the brain.
What type of vestibular specialist is right for me? Several types of health care professionals may become involved in the diagnosis, treatment, and management of dizziness and balance disorders. Below are brief descriptions of some
Vestibular Research Studies Below are clinical studies that are currently recruiting research study participants. You can find more studies recruiting patients at ClinicalTrials.gov. *If you are a VeDA professional member and would like to recruit
If you administer a vestibular disorders support group (or want to), we’re eager to help. VeDA assists support groups by publishing contact information for new or established groups as well as meeting dates and times in our Support Group Directory. We also provide administrative tools to make running a support group easy.
Invite a guest speaker Start the meeting with a lecture; allow questions from the audience afterward. Being a guest speaker at a meeting is one of the most important ways in which professionals can support
Wondering how to get your support group talking? Sometimes it just takes presenting a topic to the group and starting the conversation with some questions to promote a lively discussion. You may want to query
