Short-term self-resolution of BPPV is unlikely because the effective cure maneuvers induce strong vertigo which the patient will naturally resist and not accidentally perform. The first medical description of the condition occurred in 1921 by Róbert Bárány. [11] Approximately 2.4% of people are affected at some point in time. [1]
The Valsalva maneuver may help check for a dural tear following certain spinal operations, such as a microdiscectomy. An increase in intra-spinal pressure will cause cerebral spinal fluid (CSF) to leak out of the dura, causing a headache. [citation needed] The Valsalva maneuver has been associated with transient global amnesia. [17] [18] [19 ...
[2] [4] If this is insufficient for treating vasovagal syncope, medications such as midodrine or fludrocortisone may be tried. [4] Occasionally, a cardiac pacemaker may be used as treatment. [2] Reflex syncope affects at least 1 in 1,000 people per year. [1] It is the most common type of syncope, making up more than 50% of all cases. [2]
When a Valsalva maneuver is performed during descent with the intention of opening the Eustachian tubes, but they do not open, intrathoracic pressure, central venous pressure, spinal fluid pressure, and inner ear pressure are raised further above ambient pressure, which increases the pressure difference between perilymph of the inner ear and ...
This headache is usually occipital or sub-occipital in location (but may also present in other cranial areas), is usually dull or throbbing in character and is characteristically associated with Valsalva maneuvers (such as bearing down, coughing, sneezing, bending over or forcefully exhaling against a closed airway).
Dizziness is a common medical complaint, affecting 20–30% of persons. [4] Dizziness is broken down into four main subtypes: vertigo (~25–50%), disequilibrium (less than ~15%), presyncope (less than ~15%), and nonspecific dizziness (~10%). [5] Vertigo is the sensation of spinning or having one's surroundings spin about them. Many people find ...
The otoconia floats freely in the inner ear fluid, causing disorientation and vertigo. [1] The disorder can be tested for using a nystagmus test, such as the Dix-Hallpike maneuver. This disorder can disrupt the function of the righting reflex as the symptoms of vertigo and disorientation prevent proper postural control.
Benign paroxysmal positional vertigo (BPPV) - This is the most common cause of vertigo in adults, but it is rarer in children. Unlike BPVC, BPPV is provoked by changes in the head position. [4] Otitis media and Vestibular neuritis - Unlike BPVC, these conditions are both associated with ear pain or fullness, and the vertigo is not episodic. [3]
