What are the main manifestations of presbycusis?

1. Hearing loss is its main manifestation. Most of them are bilateral sensorineural deafness. The degree of bilateral deafness is basically the same, and it is getting worse gradually, mainly with mild and moderate hearing loss at medium and high frequencies (2 kHz-8 kHz). ?

2. Tinnitus On the basis of hearing loss, with the extension of time and the development of the course of disease, some patients with senile deafness will have high-profile tinnitus, which is intermittent or persistent. In severe cases, it will affect sleep and lead to a decline in quality of life.

3. The decline of speech resolution is mainly manifested in hearing the sound, but it is difficult to distinguish and the understanding ability is reduced. At first, this symptom only appeared in special circumstances, such as public places, where many people talked at the same time, and gradually increased to face-to-face conversation with others, which eventually led to their reluctance to talk with others and loneliness, which led to cognitive decline and increased the risk of Alzheimer's disease.

4. The phenomenon of resurrection is manifested in the low voice that others can't hear, but the loud voice makes them feel harsh. Patients often don't want to live in noisy environment.

5. Vertigo Some patients with presbycusis will be accompanied by decreased vestibular function of the inner ear, causing dizziness or vertigo, and will walk unsteadily, increasing the risk of falling.
