Hearing Loss Can Effect Your Memory

According to a 2016 study published in the Indian Journal of Otolaryngology and Head and Neck Surgery, 63 million people (6.3 per cent) suffer from significant auditory loss in India.

Hearing loss can lead to impaired memory and higher risk of dementia and ensuing Alzheimer’s disease in older people, health experts say.

Deafness, according to the World Health Organisation (WHO), refers to the complete loss of hearing ability in one or both ears, while “hearing impairment” refers to both complete and partial loss of hearing ability.

Nearly 360 million people, nearly one-tenth of them children, suffer from hearing loss worldwide.

“Yes, hearing loss can lead to cognitive decline. Our two senses — vision and hearing — contribute to our cognitive development. When we are not able to hear well, most of the information that is delivered to us that way is not received properly. This way, less hearing slowly contributes to cognitive decline,” Suresh Singh Naruka, Senior Consultant – ENT at Indraprastha Apollo Hospitals here, told IANS.

Concussion without loss of consciousness led to 2.36 times the risk for dementia, showed the findings published in the journal JAMA Neurology.

“It is important to understand that brain development and cognition development is a slow process. Intelligence is not a static thing; it is a dynamic and continuous process. It may not be visible in a day or two, but over a period of time one can witness the decline in cognitive behaviour,” Naruka added.

A study led by researchers at Brigham and Women’s Hospital in the US suggests that hearing loss is associated with new onset of subjective cognitive concerns which may be indicative of early stage changes in cognition.

The study, published in the Alzheimer’s and Dementia journal, examined 10,107 men aged 62 years.

The team found that compared with men with no hearing loss, the relative risk of cognitive decline was 30 per cent higher among men with mild hearing loss, 42 per cent higher among men with moderate hearing loss and 54 per cent higher among men with severe hearing loss but who did not use hearing aids.

The findings may help identify individuals at greater risk of cognitive decline.

It may help identify individuals at greater risk of cognitive decline and could provide insights for earlier intervention and prevention, the researchers said.

Moreover, “while hearing loss can lead to impaired memory and higher risk of dementia in older people, in children it hampers with development of speech and brain development”, Virender Singh, Consultant – ENT, Fortis Hospital, Shalimar Bagh, told IANS.

According to a 2016 study published in the Indian Journal of Otolaryngology and Head and Neck Surgery, 63 million people (6.3 per cent) suffer from significant auditory loss in India.

Four in every 1,000 children suffer from severe to profound hearing loss in India. With over 100,000 babies that are born with hearing deficiency every year, the estimated prevalence of adult-onset deafness in India was found to be 7.6 per cent and childhood-onset deafness to be 2 per cent.

“Hearing loss is a much neglected phenomenon in our country. Congenital deafness or any neonatal disease such as prolonged jaundice, meningitis or prolonged labour leading to delayed oxygenation can cause mild to profound hearing loss in neonate,” Singh said.

Hearing loss in children can hamper the development of speech and the brain. This can lead to shutting the child from worldly sounds, resulting in a disconnect from the social world.

“Early corrective measures in the form of hearing aid, cochlear implant, medications and corrective surgery should be taken as soon as possible to prevent any complications that arise from hearing loss,” Singh suggested. (IANS)

Health and lifestyle researchers have found that high consumption of fruit and vegetables is linked to lowered odds of memory loss and its co-morbid heart disease.

For the study, published in the International Journal of Public Health, the researchers studied data from 1,39,000 older Australians and found strong links between certain food groups, memory loss and co-morbid heart disease or diabetes.

The study found that higher consumption of protein-rich foods was associated with a better memory.

“Our present study implies that the healthy eating suggestions of cereals consumption in the prevention of memory loss and co-morbid heart disease for older people may differ compared to other age groups,” said the study’s researcher Luna Xu from the University of Technology, Sydney, in Australia.

She said the study pointed to a need for age-specific healthy dietary guidelines.

Memory loss is one of the main early symptoms for people with dementia, which is the second leading cause of death of Australians.

People living with dementia have on average between two and eight co-morbid conditions, which may accelerate cognitive and functional impairment.

The most common comorbidities in dementia include cardiovascular diseases, diabetes and hypertension.

“The dietary intervention in chronic disease prevention and management, by taking into consideration the fact that older populations often simultaneously deal with multiple chronic conditions, is a real challenge,” Xu said.

“To achieve the best outcome for our ageing population, strong scientific evidence that supports effective dietary intervention in preventing and managing co-occurring chronic conditions, is essential,” Xu added. (IANS)
