The drug is thought to increase blood flow to the inner ear and to prevent the frequency and intensity of episodes. While Betahistine is considered safe, there is insufficient evidence that it is an effective treatment. It is not FDA approved in the United States, yet has still been clinically observed to benefit patients, and is considered safer and more effective than diuretics. Betahistine at high doses (such as 144 mg/day) can yield similar vertigo control as intratympanic dexamethasone.Antivirals have been proven effective for those who suspect a viral cause for their cochlear Hydrops.For some, surgery may be effective, such as an endolymphatic sac decompression. Surgery is often reserved for cases where other measures have proven ineffective and/or when vestibular issues are the main complaint, as it runs the risk of causing hearing or other nerve damage. Prognosis
The symptoms of cochlear hydrops fluctuate, and the condition tends to stabilize or go away on its own after several years. However, because the organ of Corti undergoes stress during the hydrops episodes, long-term hearing loss, tinnitus, or hyperacusis is possible. It is considered by some that cochlear hydrops is an early form of Menieres disease. However, while all people with Menieres disease have some form of hydrops, the majority of cochlear hydrops patients do not go on to develop Menieres disease. It takes an average of one year from the onset of symptoms for someone to develop full Menieres disease, if at all.
Analytical techniques that can be used for PSP detection include High performance liquid chromatography (HPLC) and other forms of chromatography.These detection methods can be used on shellfish in order to determine the concentration of saxitoxin within the organism. Concentrations of saxitoxin greater than or equal to 80 ug per 100g of flesh within a shellfish are determined to be unsafe for human consumption.In terms of treatment there is no current antidote for the PSP disease that is able to combat the saxitoxin molecule. Most patients are able to recover without treatment, however biomedical devices such as mechanical respirators as well as oxygen supports can help treat any respiratory paralysis symptoms until the toxin passes through the patients body
