Menieres Disease
  • By Cindy Infante
  • Psychology (HONORS)

2
What is Menieres 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.

3
Ménière disease was first described in 1861 by
the French physician Prosper Ménière.
4
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.

5
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

6
How is Menieres 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.

7
Target Population
  • Ménière disease affects people of all ages,
    especially those of middle age or older. It is,
    however, uncommon in children
  • Menieres 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 Menieres disease,
    suggesting that there is considerable chance of
    misdiagnosis.

8
Affects with CNS/PNS
  • An acute attack of Menieres 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 Menieres is questionable, as many normal
    people without Menieres 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

10
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.

11
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.
