Expert explains how wearing earplugs at concerts protects against dementia

Dementia remains a progressive and irreversible neurological condition, yet recent evidence suggests that prevention through lifestyle adjustments is possible.

Dr Rupa Juthani, a US-based neurosurgeon, shared insights on Instagram on March 22 regarding the link between auditory health and cognitive decline.

She stated, “Hearing loss is the number one modifiable risk factor for dementia.” Even short exposure to high volumes can lead to permanent damage.

How concerts damage the ear

After attending loud events, many experience ringing or muffled sounds. Dr Juthani explained that when sound exceeds 85 dB, it mechanically stresses cochlear hair cells.

She noted, “The first response is a Temporary Threshold Shift, which means hearing dims, tinnitus kicks in, and it typically clears within 16 to 48 hours.” However, she warned that minutes in a loud environment can trigger permanent loss as hair cells do not regrow.

How does hearing loss affect the brain?

The Lancet Commission on Dementia has identified hearing loss as the single largest modifiable risk factor from midlife. Dr Juthani elaborated:

• Dementia risk rises 16 percent for every 10 dB of hearing loss.
• Concerts routinely hit 100 to 110 dB.
• Repeated exposures make temporary shifts permanent.

Simple foam earplugs are inexpensive and effective. For those concerned with aesthetics, decorative or musician-grade versions are available.

These protect the ears while maintaining sound quality. Dr Juthani concluded, “Protecting hearing is protecting your brain.”

By taking these small precautions, individuals can significantly lower their risk of developing incurable neurological disorders later in life.
