Menieres Disease : Tests

A neurologic examination may show an abnormality of cranial nerve VIII that may include abnormalities of hearing, balance, or eye movement. Tests to distinguish Meniere's disease from other causes of vertigo may include: Head CT scan or head MRI s...

Meniere's disease is a disorder characterized by recurrent vertigo, sensory hearing loss, tinnitus, and a feeling of fullness in the ear. It is named for the French physician, Prosper Meniere, who first described the illness in 1861. Meniere's dis...

Meniere's disease is a condition characterized by recurrent vertigo ( dizziness ), hearing loss , and tinnitus (a roaring, buzzing, or ringing sound in the ears).

Audiometry is the testing of a person ' s ability to hear various sound frequencies. The test is performed with the use of electronic equipment called an audiometer.

Audiometry is performed to test a person's ability to hear the sound frequencies necessary for speech. The test is carried out by a trained specialist called an audiologist with an instrument called an audiometer.

Audiometry encompasses those procedures used to measure hearing thresholds. Purpose The purpose of audiometry is to establish an individual ' s range of hearing.

The brainstem auditory evoked response (BAER) test measures brain wave activity that occurs in response to clicks or certain tones.

Evoked Potential TestingYour doctor may order evoked potential tests to check the signals your brain and spinal cord (parts of your nervous system) receive from other parts of your body. These tests are also used to check for vision and hearing pr...

Caloric stimulation is a test which uses differences in temperature to diagnose ear nerve damage.

Electronystagmography is a test to look at voluntary and involuntary eye movements. It evaluates the acoustic nerve, which aids with hearing and balance.

A tuning fork is a metal instrument with a handle and two prongs or tines. Tuning forks, made of steel, aluminum, or magnesium-alloy will vibrate at a set frequency to produce a musical tone when struck.

During the process of choosing a hearing aid, your hearing will be carefully tested by an audiologist. The test results, called an audiogram, will show whether your ears are healthy, what type of hearing loss you have, and exactly what you can and cannot hear.

What Is an Audiogram?The results of your hearing test are shown on a graph called anaudiogram.This graph shows which types of sounds you can and can’t hear.

Is an auditory brainstem response test a usual thing to have done for hearing loss?

During a physical examination, a health care provider studies a patient's body to determine the presence or absence of physical problems. A typical physical examination includes: Inspection (looking at the body; Palpation (feeling the body with hands; Auscultation (listening to sounds; Percussion (producing sounds.

An MRI of the head is a noninvasive procedure that uses powerful magnets and radio waves to construct clear, detailed pictures of brain tissues. Conventional radiography and computed tomographic (CT) imaging use potentially harmful radiation (x-rays) that passes through a patient to generate images. Magnetic resonance imaging (MRI) is based on the magnetic properties of atoms, and there is no exposure to the same type of radiation used in x-rays and CT scans. A powerful magnet generates a magnetic field roughly 10,000 times stronger than the Earth's. A very small percentage of hydrogen atoms within the body will align with this field. Radio wave pulses are broadcast towards the aligned hydrogen atoms in tissues of interest, returning a signal of their own. The slight differences of those signals from different tissues enables MRI to tell the difference between various organs, and potentially, provide contrast between benign and malignant tissue. Any imaging angle, or "slice", can be projected, and then stored in a computer or printed on film. MRI can easily be performed through clothing and bones. However, certain types of metal in or around the area of interest can cause significant errors in the reconstructed images. These errors are called artifacts.

A neurological examination is an essential component of a comprehensive physical examination . It is a systematic examination that surveys the functioning of nerves delivering sensory information to the brain and caring motor commands (Peripheral nervous system) and impulses back to the brain for processing and coordinating (Central nervous system).
