With the increase of age, due to various reasons in daily life, the function of hair cells may decline, so the older you get, the more hair cells fall off, and the more likely you are to be deaf. After the second old man's ear and cochlea function deteriorated, the whole blood supply gradually deteriorated.

It is true that the incidence of deafness in the elderly is relatively high. A recent survey found that about 33% of the elderly will be deaf.

Deafness occurs in the elderly, and many people's diagnosis is that they are old and their nerves are degenerated. This is actually one of the reasons why this kind of functional neurodegeneration does occur in the elderly.

The other is that many recent studies have found that one of the reasons for deafness in the elderly may be because of the ears. Finally, his nervous deafness depends on the function of the cells inside. The cells in this person's ear are different from those in his skin. It is non-renewable, that is, one cell dies and another cell dies. With the growth of age, due to various reasons in daily life, the function of this hair cell may decline, so it may be age.

The second is in the ears of the elderly. After the function of cochlea degenerates, its overall blood supply gradually deteriorates, which is also an important cause of deafness.
