Wear hearing protection in very noisy environments, such as concerts, to avoid irreversible damage to the inner ear and thereby reduce the long-term risk of cognitive decline and dementia.

Carla is entirely correct regarding the biology: inner ear hair cells do not regenerate in humans after acoustic trauma, a solidly established fact. Her statement on the link between hearing and the brain is supported by very robust data, notably the 2024 Lancet Commission consensus report, which ranks midlife hearing loss as the leading modifiable risk factor for dementia. A vast meta-analysis of 31 studies published in JAMA Neurology also confirms that untreated hearing decline significantly increases the risk of cognitive impairment. Scientists explain this link through increased brain fatigue from decoding sounds, atrophy of understimulated cognitive areas, or social isolation. While there is no clinical trial directly measuring the impact of concert earplugs on future dementia, this preventive measure remains a logical recommendation validated by experts for preserving cognitive capital. The creator's phrasing is indeed scientifically rigorous, as she discusses an association and a risk factor without inventing a simplistic causality.
