About hearing loss

Methods for detecting pseudo deafness

There are two methods for distinguishing pseudo deafness: behavioral audiometry and electrophysiological testing.

Behavioral audiometry is subjective. In order to prevent the pseudo deaf from cheating in the test, we will adopt different test methods. For example: self tracing audiometry, Lombard reflex test, Stenger test, tuning fork midline bone conduction test, etc.

Physiological test refers to the use of objective auditory physiological tests to detect the physiological function of the auditory system to identify whether patients have non organic hearing loss. For example: Acoustic reflex threshold test, Auditory brainstem response, Otoacoustic emission, 40Hz auditory potential, etc

 Correlation between senile dementia and hearing loss

Hearing loss means that the sound stimulus is reduced. With the passage of time, the central auditory processing cortex functions deteriorate, and the brain cannot process the received signals, which will affect people’s cognitive ability. According to WHO data, the elderly with mild, moderate and severe hearing loss are twice, three times and five times more likely to suffer from dementia than those with normal hearing.

Hearing loss leads to inability to hear clearly let alone just hear external sounds, which affects social interaction and cognition. Being unable to socialize makes people feel isolated and out of touch with others. Long term depression may lead to anxiety, and other psychological diseases, accelerating cognitive impairment.

Correlation between depression and hearing loss

Once hearing loss occurs, it will bring more or less inconvenience to life, so it is easy to have depression, inferiority, regret and other psychological diseases. If you do not give timely counseling, you will suffer from depression. People with severe and extremely severe hearing loss suffer less depression than those with mild and moderate hearing loss. This is because people with severe hearing loss are psychologically more likely to receive rehabilitation treatment, such as wearing hearing aids or cochlear implants, while people with mild hearing loss are mostly indifferent or face saving, which leads to hearing failure to be compensated in a timely manner, thus affecting their lives and emotions. People with severe hearing loss may suffer from depression.
