Benign paroxysmal positional vertigo
ICD-10 H81.1
ICD-9 386.11

Benign paroxysmal positional vertigo (BPPV) (or "Benign paroxysmal vertigo") is a condition caused by problems in the inner ear. Although its cause is not certain, it is most likely due to a build up of calcium in the semicircular canals of the inner ear. The principal symptom is a sudden, intense feeling that either one is spinning or the room is spinning, which usually occurs with movement of the head into specific positions. Dizziness or vertigo, lightheadedness, imbalance, nausea and vomiting are common, however symptoms vary greatly between individuals. The classic patient complaint is sudden onset of vertigo when rolling over in bed. Other symptoms include vision and hearing problems, poor memory or confusion, coordination issues, and fatigue. The following codes are used with International Statistical Classification of Diseases and Related Health Problems. ...

Vertigo, sometimes called a headrush, is the sensation of spinning while the body is stationary. ...

Vision problems can include nystagmus, seeing objects 'jump', difficulty reading and/or writing, increased night blindness, and poor depth perception. Look up Nystagmus in Wiktionary, the free dictionary Nystagmus is rapid involuntary rhythmic eye movement, with the eyes moving quickly in one direction (quick phase), and then slowly in the other (slow phase). ... Nyctalopia (literally night blindness) is a condition making it difficult or impossible to see in the dark. ... Depth perception is the visual ability to perceive the world in three dimensions. ...


Hearing problems may include hearing fluctuations, a feeling that the ear is 'full', or aches, and tinnitus in which you may hear buzzing, clicking, or popping. Tinnitus, ringing ears or ear noise is a phenomenon of the nervous system connected to the ear, characterised by perception of a ringing or beating sound (often perceived as sinusoidal) with no external source. ...


Nausea may be present, continually or intermittently. There may be a feeling of motion sickness, or a 'hangover' with a seasick sensation in the head and/or stomach.


Memory may become poor. Groping for words or forgetting your point in the middle of a sentence, confusion, disorientation, and an inability to comprehend directions or instructions may occur.


Coordination is often effected, causing clumsiness, difficulty walking straight, slurred words, a feeling of rocking (as if in a boat), center of balance is off, a sensation of weights on the head, or balance may be normal due to compensation with vision or touch senses. Coordination or Co-ordination is the regulation of diverse elements into an integrated and harmonious operation. ...


Emotions are often effected, as with any long lasting disorder. Loss of self-reliance, self-esteem, self-confidence, along with depression and a distracted feeling may be noticed, especially as driving may become more difficult or impossible and keeping a job may become impossible due to a combination of all these factors. Look up depression in Wiktionary, the free dictionary. ...


Fatigue is common. Daily tasks may be exhausting. Fatigue may refer to: Fatigue (physical) - tiredness in humans Fatigue (material) - failure by repeated stress in materials Fatigues (uniform) - military uniform (BDU or ACU) Chronic Fatigue Syndrome - a medical condition Battle fatigue - also known as Post-traumatic stress disorder Readers fatigue - a side-effect of parsing poorly formatted textual...


Circumstances that may exacerbate symptoms include rapid temperature changes (like a hot shower or freezer section of the grocery store), florescent lighting, loud environments, watching tv with rapid camera movement, seeing someone 'talk with their hands', or driving down a road with shadow and bright spots caused by trees. Altitude changes, wind currents, pressure changes and being over-tired may also worsen symptoms.


The treatment of choice for this condition is repositional techniques (the Epley and Semont Maneuvers, employ gravity to move the calcium buildups that are causing the condition). The medicine meclizine is commonly prescribed but its effectiveness is controversial. Gravity is a force of attraction that acts between bodies that have mass. ...

Cautions in treatment and management of vertigo include cautions against the sedative effect of meclizine, which can produce extreme drowsiness. Also, vertigo, nausea, and vomiting are very early signs of stroke and early signs of brain tumor, so anyone with these symptoms should take immediate steps to rule out these problems and confirm the diagnosis of BPPV. A stroke, also known as cerebrovascular accident (CVA), is an acute neurologic injury whereby the blood supply to a part of the brain is interrupted, either by a clot in the artery or if the artery bursts. ... A brain tumor is any intracranial mass created by an abnormal and uncontrolled growth of cells either normally found in the brain itself: neurons, glial cells (astrocytes, oligodendrocytes, ependymal cells), lymphatic tissue, blood vessels), in the cranial nerves (myelin producing Schwann cells), in the brain envelopes (meninges), skull, pituitary and...


Once the condition is diagnosed and other problems ruled out, home treatment may include use of the Brandt-Daroff Exercises or, if the affected ear is known, a self-treatment version of the Epley maneuvers. These treatments are effective in about 90% of BPPV cases. Surgery may also be available, but only as a last resort as it may cause hearing loss.

Head apparatus and assistant device for the treatment of BPPV - Patent 6758218 (20133 words)
BPPV is classically used to refer to vertigo caused by loosened otoconia crystals in the posterior semicircular canal, the most common inner ear semicircular canal effected by loosened otoconia.
BPPV is caused by 1) naturally occurring calcium carbonate crystals becoming dislodged and falling from their normally occurring position on the utricular macula and 2) a significant number of the crystals coming to be located in a membranous semicircular canal.
According to Fife.sup.1, 91% of the BPPV patients were thought to have involvement of the posterior semicircular canal, 6% involvement of the horizontal canal (7.8% according to Takegoshi.sup.2), and 3% involvement of the superior (or anterior) semicircular canal.
Benign Paroxysmal Positional Vertigo - BPPV - Maryland Hearing and Balance Center (1072 words)
Benign Paroxysmal Positional Vertigo, BPPV (sometimes also referred to as BPV) is the most common cause of bouts of vertigo in the general population.
BPPV is thought to be caused by displacement of otoliths (mineral crystals) from the vestibule of the inner ear into the semicircular canals.
Another surgery that has been used for BPPV is division of the singular nerve, the small branch of the inferior vestibular nerve that breaks off to supply the posterior semicircular canal.
