Answers 100% Pass


Why do you think that improved hearing aid technology has been shown

to have a positive impact on cognitive function in individuals with hearing

loss? - ANSWER✔✔-Improved hearing aid technology has been shown to

have a positive impact on cognitive function in individuals with hearing

loss because cognitive function and hearing ability have a relationship, and

cognitive function and hearing aid technology are also related.


Evidence is growing that the cognitive ability of a patient affects the benefit

they receive from hearing aid technology. Cognitive ability can be a better

predictor of hearing aid benefit to speech understanding in complex

listening environments than the audiogram, where cognitive function is

necessary to separate the talker from other simultaneous talkers and focus

attention on that target speaker. Hearing aid technology significantly

affects a patient's hearing ability, most notably increasing audibility and

improving speech understanding. Some effects of technology on hearing

,can be difficult to quantify, such as the impact of technology on spatial

hearing, pitch perception, and other complex auditory functions. The

complexity with which we consider patient needs and benefit from

treatment has increased over the past decade through the added

consideration of cognitive function.


Patients with lower levels of cognitive functioning may be at greater risk

for poor satisfaction with and possible rejection of their hearing aids.

Likely, these patients would benefit from a longer period of counseling,

education, and training on topics such as expectations for hearing reha-

bilitation, hearing aid care, and use of hearing aids, including manual

adjustments and battery changes.


Hearing aid noise reduction can reduce cognitive load, making listening to

speech in noise easier for the hearing aid wearer even if speech

understanding isn't improved. Reduction in listening effort over a period

of time can have the effect of reducing listening fatigue, a problem

experienc


Briefly describe the relationship between hearing loss and cognitive decline

in older individuals. - ANSWER✔✔-Multiple studies have indicated that

Copyright ©EMILLYCHARLOTE 2025 ACADEMIC YEAR, ALL RIGHTS RESERVED. Page 2/55

,hearing loss may be a significant causative factor with regard to cognitive

decline in older adults. Although some speculate against it, it has been

proposed the association between hearing loss and cognitive impairment

could be the result of an underlying common pathology. This means that

the etiology of hearing loss and cognitive decline could possibly share a

common foundation, such as vascular disease. The relationship between

cognitive function, cognitive decline, hearing, hearing loss, listening

ability—and the potential to maintain or (perhaps one day) improve

cognitive ability through amplification remains promising, but essentially

unknown and as of yet unproven, in 2015.


Hearing sensitivity worsens with increased age, and this is associated with

poorer speech intelligibility. Age-related changes in supra-threshold

auditory processing and cognition—that is, factors not captured by a

traditional audiometric assessment—contribute to the speech-identification

difficulties of older people.


Brains change and "re-wire" as a result of auditory deprivation, and when

the brain is not stimulated via audition, the auditory processing centers in

the temporal lobe can (and do) become recruited to perform other brain

, functions such as somatosensory and visual processing functions.

Although it appears that amplification may offer promise for the hearing-

impaired patient to help maintain or improve cognitive function, those

studies are as yet incomplete. However, new and important information

specifically addressing these (and related) concerns are being published,

availing a stream of interesting and related information.


Cognitive function affects hearing ability in very direct ways. For example,

the ability to focus attention on different talkers in a crowded room is one

top-down benefit


How would you explain to this individual why it is important that their

hearing loss not go unmanaged? - ANSWER✔✔-Hearing occurs in the

brain. It is where sound (speech) is processed and interpreted. When

hearing loss is unmanaged and the brain is not receiving that auditory

stimulation, the neural pathways from the ear to the brain can deteriorate.

This leads to more difficulty processing and understanding speech, and can

accelerate cognitive decline. It also impacts mental health and can

contribute to feelings of depression and withdrawal.
