This is referred to as excessive earwax or impacted cerumen. [21] Excessive earwax may impede the passage of sound in the ear canal, causing mild [22] conductive hearing loss, pain in the ear, itchiness, or dizziness. Untreated impacted wax can result in hearing loss, social withdrawal, poor work function, and mild paranoia.
This typically causes impaired nerve function, increased pressure within the skull, and can eventually lead to direct compression of brain tissue and blood vessels. [1] Symptoms vary based on the location and extent of edema and generally include headaches , nausea, vomiting, seizures, drowsiness, visual disturbances, dizziness, and in severe ...
Reverse block can also occur on descent if the external auditory canal is blocked by an earplug, tightly fitting diving hood, severe exostoses or impacted cerumen. A blockage of the external auditory canal is also a common cause of inner ear barotrauma.
These symptoms are not symptoms of Ménière's disease per se, but rather are side effects resulting from failure of the organ of hearing and balance, and include nausea, vomiting, and sweating, which are typically symptoms of vertigo, and not of Ménière's. [1] This includes a sensation of being pushed sharply to the floor from behind. [5]
Additionally, cerumenolytics can also facilitate the manual removal of ear wax. [1] Overall, all cerumenolytics are considered to be equivalent in efficacy. [ 2 ] Cerumenolytics are administered directly into the ear, which is a form of topical administration that can be specified as "ototopical."
The conditions that cause secondary (referred) ear pain are broad and range from temporomandibular joint syndrome to inflammation of the throat. [3] In general, the reason for ear pain can be discovered by taking a thorough history of all symptoms and performing a physical examination, without need for imaging tools like a CT scan. [3]
The researchers don't know why the 12 brains they tested from people who had dementia had more plastic than those that didn't and don't know if it's cause or effect. But they're leaning toward effect.
Flicker vertigo, sometimes called the Bucha effect, is "an imbalance in brain-cell activity caused by exposure to low-frequency flickering (or flashing) of a relatively bright light." [ 1 ] It is a disorientation -, vertigo -, and nausea -inducing effect of a strobe light flashing at 1 Hz to 20 Hz, approximately the frequency of human brainwaves .
