BPPV is characterized by - CORRECT ANSWER a sensation of spinning, whirling, or tilting with movement or position change
BPPV is the most common
... [Show More] disorder among which population of patients? - CORRECT ANSWER Older adults
Otoconia refers to - CORRECT ANSWER debris in the inner ear made up of small crystals of calcium carbonate. With certain position changes, these crystals shift and disperse within the semicircular canal, sending false signals to the brain.
Symptoms of BPPV are precipitated by - CORRECT ANSWER a change in head position
What is The most characteristic description of BPPV - CORRECT ANSWER vertigo, which may be a sensation of spinning or whirling of oneself or the environment
The nystagmus associated with BPPV is characteristic, and any deviation from the typical profiles should suggest a central lesion
Common movements that precipitate BPPV - CORRECT ANSWER this vertigo are rolling over in bed, arising or turning abruptly, or first lying back on the bed.
How do you observe nystagmus? - CORRECT ANSWER Hallpike-Dix maneuver
if it is vertical or torsional in nature and lasts less than 30 seconds, it is consistent with a posterior semicircular canal variant.
If the nystagmus is direction changing and horizontal (beating toward the ground) and lasts about 1 minute, it is consistent with a horizontal canal varian
Physical examination of one with BPPV - CORRECT ANSWER history and physical examination
The Hallpike-Dix maneuver can be diagnostic of BPPV if the nystagmus is of the characteristic profile previously described. The dizziness and vertigo will be elicited with the affected ear down.
Diagnostic testings for BPPV - CORRECT ANSWER may be confirmed by history and a positive Hallpike-Dix test result.
Further testing is warranted if there are positive neurologic findings, any associated features beyond the vertigo and a mild imbalance, or any symptoms or findings that are not movement or position related
Management of BPPV - CORRECT ANSWER The CANALITH REPOSITIONING PROCEDUREcanalith is a specific positioning exercise that is designed to move ear crystal particles from the semicircular canal. If BPPV is confirmed, this is the FIRST LINE TREATMENTf rather than the commonly prescribed vestibular suppressant meclizine
Medications for the treatment of BPPV - CORRECT ANSWER Medications such as meclizine may be used as a vestibular suppressant if vertigo is severe.
However, in BPPV, the acute attacks are not suppressed by medications, and canalith-repositioning maneuvers are more effective in controlling the condition
Medications that cause vestibular suppression slow recovery because they slow compensatory mechanisms
Education and Health Promotion of those diagnosed with BPPV - CORRECT ANSWER It is important to emphasize that the most effective treatment (vestibular therapy and exercises) may initially cause increased symptoms, but the treatment must continue for the symptoms to subside. [Show Less]
