Meniere Disease
What is Meniere disease?
Meniere disease, also called idiopathic endolymphatic
hydrops, is a
disorder of the inner ear. Although the cause of Meniere
disease is
unknown, it probably results from an abnormality in the way
fluid of the
inner ear is regulated. In most cases only one ear is involved,
but both
ears may be affected in about 15% of patients. Meniere
disease typically
starts between the ages of 20 and 50 years of age. Men and
women are
equally affected. The symptoms may be only a minor nuisance, or
can become
disabling, especially if the attacks of vertigo are severe,
frequent, and
occur without warning.
What are the symptoms of Meniere disease?
The symptoms of Meniere disease typically include at least
several of
the following:
- Episodic rotational vertigo: Attacks of a spinning sensation
accompanied by disequilibrium (an off-balanced sensation),
nausea, and
sometimes vomiting. This is usually the most troublesome
symptom. The
vertigo usually last 20 minutes to two hours or even longer.
During
attacks, patients are very disabled, and sleepiness may
follow. An
off-balanced sensation may last for several days.
- Tinnitus: A roaring, buzzing, machine-like, or ringing
sound in the
ear. It may be episodic with an attack of vertigo or it may
be constant.
Usually the tinnitus gets worse or will appear just before
the onset of
the vertigo.
- Hearing loss: It may be intermittent early in the onset of
the
disease, but overtime it may become a fixed hearing loss. It
may involve
all frequencies, but most commonly occurs in the lower
frequencies. Loud
sounds may be uncomfortable and appear distorted in the
affected ear.
- Ear fullness: Usually this full feeling occurs just before
the onset
of an attack of vertigo.
