What are hearing evoked potentials?
Hearing evoked potentials or brain strain Auditory evoked response (Baer) is a medical test that some doctors use to evaluate the electrical activity of the patient's brain waves. This hearing screening test is usually used to monitor the health of paths in the brain and neurological functions associated with these ways. The test of the sound evoked potential can help the physician diagnose some causes of hearing loss and nervous system disorders. Abnormal results of the test of sound evoked potentials may be the result of health conditions such as multiple sclerosis or stroke, in some cases the physician may decide to test the sound of the induced potential to explore the symptoms of patients such as vomiting, nausea and loss of balance. The presence of headaches, hearing loss and abnormal ringing in the patient's ears may indicate a neurological disorder that in some cases can be identified or diagnosed with this test. Some patients with a visionMS and feelings of numbness can also have problems of the nervous system and can benefit from administering this test.
before the auditory potential test, the patient usually sits on a chair because the medical technologist holds four electrodes in the head. Electrodes are usually connected to an electronic device that records brain wave activities. The patient usually wears headphones over both ears. In most cases, clicking on sounds is played in one ear for a few minutes and then they play in the other ear. This click may seem audible or inaudible to the patient, but the attached recording device usually measures any brain activity that develops in response to these clicks.
abnormal reactions to the test of sound evoked potentials may in some cases indicate hearing loss. Newborns are usually evaluated with this type of test to identify with an awakenedWe with hearing are present at birth. Generally the most common types of hearing loss are conductive hearing loss and sensorineural hearing loss. The conductive hearing loss is usually caused by mechanical disorders in the transmission of sounds from the outer ear through the middle ear. Sensorineural hearing loss usually develops from inner ear disorders that affects sound transmission through the auditory nerve to the brain.
In some cases, the auditory evoked potential test may have abnormal results due to multiple sclerosis or stroke. Patients with multiple sclerosis usually have brain and spinal cord damage that can lead to hearing loss. In this medical disorder, the balance and loss of vision may also occur. Doctors may have the patient to test the potential of potential for parallel to other medical tests such as neurological examination and eye examination. In some cases, testing of evoked sound potentials can bring abnormal results dueA stroke that causes hearing problems and other functions of the nervous system.
