-
- Benign Paroxysmal Positional Nystagmus is a disorder of the vestibular
- system in the middle ear which causes dizziness due to altered function of
- the semicircular canals, usually the posterior canal. The disorder is
- paroxysmal because the dizziness takes place without warning, it is
- positional because the symptoms increase with certain movements of the head
- or body, and abnormal eye movements or nystagmus accompanies the dizziness.
-
- Symptoms
-
- Benign Paroxysmal Positional Nystagmus (BPPN) is characterized by episodes of
- violent dizziness triggered by certain head positions, and often accompanied
- by nausea, vomiting and impaired muscle coordination (ataxia). Involuntary
- rhythmic oscillation of the eyes (nystagmus) in a horizontal, vertical or
- circular direction usually also occurs. The symptoms usually last only a few
- weeks or months, and may disappear spontaneously.
-
- Causes
-
- Benign Paroxysmal Positional Nystagmus (BPPN) may be caused by one of several
- different mechanisms affecting the semicircular canals of the inner ear.
- These may include spontaneous degeneration of the membranes in the labyrinth
- of the ear, head injuries, serious middle ear infection, ear surgery, and
- closing off of the anterior vestibular artery in the inner ear.
-
- Affected Population
-
- BPPN primarily affects females during middle or late adulthood.
-
- Related Disorders
-
- Meniere Disease is a disorder characterized by recurrent prostrating attacks
- of dizziness (vertigo), possible hearing loss and ringing sounds (tinnitus).
- (For more information on this disorder, choose "meniere" as your search term
- in the Rare Disease Database.)
-
- Vestibular Neuronitis of Dix and Hallpike is a disorder of unknown cause,
- with abrupt onset during young adulthood and continuing through the fifth
- decade of life. It is characterized by dizziness, nausea and vomiting. Head
- movements may make the symptoms more severe. Hearing is usually not
- impaired. This disorder is often associated with upper respiratory tract
- infections and fever.
-
- Therapies: Standard
-
- Patients with BPPN are advised to avoid head movements that could bring on
- the attacks. Medications can be used to decrease dizziness, to control
- nausea or vomiting. If the dizziness is caused by bacterial infection in the
- ear, antibiotics may help.
-
- A well-balanced diet is important. Salt, alcohol and caffeine intake
- should be reduced.
-
- Therapies: Investigational
-
- A surgical treatment used in some cases of acoustic nerve compression is
- known as the Jannetta procedure. This type of surgery may be helpful in some
- cases of BPPN. For more information on this type of experimental surgery,
