Dementia Risk: Neurologist Warns against Common Bedtime Habit
A leading neurologist is sounding the alarm about a seemingly harmless nighttime habit – wearing headphones – linking it to an increased risk of dementia. Dr. Janette Nesheiwat warns that prolonged, high-volume headphone use can contribute to hearing loss, now identified as a major risk factor for the debilitating neurological condition.
The warning comes as a new 2024 study published in The Lancet explicitly lists hearing loss as a significant contributor to dementia growth. With an aging global population and rising rates of noise-induced hearing loss from personal audio devices, the potential impact is substantial. Early detection of hearing loss and preventative measures are crucial, as dementia currently affects millions worldwide and carries a profound personal and societal cost.
Dr. Nesheiwat explained that consistent exposure to loud sounds through headphones damages the delicate hair cells in the inner ear, leading to gradual hearing decline. “Hearing loss isn’t just about not being able to hear; it’s about depriving the brain of stimulation,” she said. “When the brain doesn’t receive enough auditory input, it can lead to cognitive decline and an increased risk of dementia.”
The symptoms of dementia can manifest in various ways, including:
* Memory loss
* Difficulty concentrating
* Challenges performing familiar daily tasks
* Struggles with conversation and word recall
* Confusion regarding time and place
* Mood changes
Anyone experiencing these symptoms, or concerned about their hearing, is urged to seek professional medical advice promptly. Early diagnosis and intervention for both hearing loss and dementia are vital for managing the condition and improving quality of life.
