Meniere’s Disease By: Cindy Infante Psychology (HONORS) What is Meniere’s Disease ? • Ménière disease is a syndrome in which you experience episodes of spinning vertigo (sense of the room spinning), hearing loss, and tinnitus (ringing in the ear). Between the unpredictable attacks, you usually do not have any problems or symptoms of the disease. Ménière disease was first described in 1861 by the French physician Prosper Ménière. Causes • The cause of Meniere's disease isn't well understood. It appears to be the result of the abnormal volume or composition of fluid in the inner ear. Factors that alter the properties of inner ear fluid may help cause Meniere's disease. • Improper fluid drainage, perhaps because of a • • • • • • blockage or anatomic abnormality Abnormal immune response Allergies Viral infection Genetic predisposition Head trauma Migraines How is Meniere’s disease diagnosed? • Diagnosis is based on a combination of the right set of symptoms (usually episodic dizziness and hearing disturbance); hearing tests, which document that hearing is reduced after an attack, and then gets better; and exclusion of alternative causes. Target Population • Ménière disease affects people of all ages, especially those of middle age or older. It is, however, uncommon in children • Meniere’s disease affects roughly 0.2% of the population. Interestingly, the Framingham study found that 2% of the population of the United States believe they have Meniere’s disease, suggesting that there is considerable chance of misdiagnosis. Affects with CNS/PNS • An acute attack of Meniere’s disease is generally believed to result from fluctuating pressure of the fluid within the inner ear. This is called “hydrops”. A system of membranes, called the membranous labyrinth, contains a fluid called endolymph. The membranes can become dilated like a balloon when pressure increases. One way for this to happen is when the drainage system, called the endolymphatic duct or sac is blocked. In some cases, the endolymphatic duct may be obstructed by scar tissue, or may be narrow from birth. In some cases there may be too much fluid secreted by the stria vascularis. Recently, some have pointed out that this “central hypothesis” of Meniere’s is questionable, as many normal people without Meniere’s have evidence of increased pressure in the inner ear too. Symptoms • • • • • • • • • • • Hearing loss Ringing in the ear (tinnitus) Feeling of fullness in the ear Headache that is unusual or severe for you Double vision or loss of vision Speech impairment Leg or arm weakness Loss of consciousness Falling or difficulty walking Numbness or tingling Chest pain Prognosis • Ménière's disease often can find the right combination of lifestyle changes and medication to reduce the frequency and severity of attacks. Patients with severe, disabling symptoms may get relief with surgery, but the risks and benefits need to be weighed carefully. Cure / Vaccine or Treatment • • • • • • No cure exists for Meniere's disease, but a number of strategies may help you manage some symptoms. Research shows that most people with Meniere's disease respond to treatment, although long-term hearing loss is difficult to prevent. Long-term medication use Noninvasive therapies and procedures Rehabilitation Hearing Aid Meniett Device- For vertigo that's hard to treat, this therapy involves the application of positive pressure to the middle ear to improve fluid exchange. A device called a Meniett pulse generator applies pulses of pressure to the ear canal through a ventilation tube. The treatment is performed at home, usually three times a day for five minutes at a time. Notable Case • Alan Shepard - (November 18, 1923 - July 21, 1998) was the first American in space and the fifth person to walk on the moon, commanding the Apollo 14 mission. In the early 1964 Shepard was diagnosed with Meniere's Disease. The condition caused him to be removed from flight status for most of the 1960's as the disease cause disorientation, dizziness and nausea. In 1963 Shepard was designated Chief of the Astronaut office which involved monitoring the coordination, schedule, and control of all activities involving the NASA astronauts. Shepard was eventually restored to full flight status by 1969 after going through corrective surgery. At the age of 47 years old, he was the oldest astronaut in the program when he took part in his second space flight as commander of the Apollo 14.
