What are the causes of hearing loss in the elderly? Many people grow old and become deaf and dazzled. To most people, it looks like a normal aging process. But these can also be prevented and avoided. Although the incidence of hearing loss in the elderly is high, it also seriously affects the quality of life of the elderly. Therefore, we should first find out the cause and prevent it. Natural aging can lead to hearing loss𞓜 It is well known that aging has a certain impact on the function of hearing organs. Aging of the auditory organs is a natural physiological phenomenon, mainly due to the thickening and hardening of the cochlear basement membrane without significant loss of cochlear hair cells and auditory nerves. The incidence of hearing loss gradually increases with age and reaches 70
remained the same at age 2. The prevalence of hearing loss in urban populations was lower than in rural areas by economic and educational level, suggesting that hearing loss is associated with regional socioeconomic differences. Hearing loss is negatively correlated with socioeconomic forms such as income and education level. High educational level is a protective factor for hearing loss in all frequency bands in the elderly. The reasons may be high education level, more external information stimulation, good nervous system exercise, and faster nerve conduction, thereby delaying or avoiding hearing loss. Diabetes is associated with hearing loss in certain chronic diseases. Diabetes can cause slowly progressive bilateral symmetrical sensorineural hearing loss in the elderly. The degree of hearing impairment in the elderly with hyperglycemia was significantly higher than that in the normal elderly. So far, the mechanism by which hyperglycemia causes hearing loss is unclear. It is mainly believed that the chain reaction of hyperglycemia and hyperlipidemia leads to osmolarity syndrome.
On the one hand, the osmotic pressure of the inner ear labyrinth lymph changes, which affects the blood and oxygen supply of the inner ear and the normal circulation of the inner ear lymph, resulting in damage to the sensory system
Diabetes, on the other hand, damages cochlear nerve cells, causing an imbalance in the metabolism of the patient’s nerve cells, resulting in slower nerve conduction. Hyperlipidemia is also associated with hearing loss in older adults. Hyperlipidemia is a risk factor for accelerated presbycusis, especially in the middle and high frequency regions; among them, high cholesterol is a risk factor for hearing damage in the high frequency group, and the onset of hyperlipidemia such as hyperlipidemia and hyperlipidemia The mechanism may be related to hyperlipidemia and hyperlipidemia. Hypoxia in the inner ear and brain center makes hair cells near the basement membrane of the cochlea more susceptible to high-frequency stimulation, which affects the transmission of nerve impulses in the auditory pathway, leading to slowly progressive sensorineural deafness, and high-frequency hearing loss is more common in older adults , rather than low frequencies.
Although the incidence of hearing loss is higher in the elderly, it also affects the quality of life of the elderly. Therefore, we should first find out the reasons, and then prevent
