Crema, Italy – Protecting hearing isn’t just a concern for adults. it’s a critical aspect of child development and overall health. Dr. Stefano Passerini, an otorhinolaryngologist at Maggiore Hospital of Crema, emphasizes the importance of early detection and intervention when it comes to hearing loss in children and adults alike. Dr. Passerini, who earned his medical degree from the University of Milan in 1987 and specialized in otorhinolaryngology in 1991, has been a leading voice in ear, nose, and throat care in the region since 1996.
Recognizing the subtle signs of hearing decline is the first step toward addressing potential problems. Dr. Passerini explains that these signs are often gradual and easily dismissed. “They are often subtle and progressive, for this reason many people underestimate them, attributing them to distraction or fatigue,” he says. “These include difficulty understanding words in noisy environments, needing to turn up the volume on the television, and struggling to follow group conversations.” Less obvious indicators, he adds, include a tendency to avoid conversations that require significant listening effort. More urgent signals include a sudden drop in hearing or a persistent ringing in the ears.
The Link Between Hearing and Cognitive Health
Emerging research highlights a strong connection between hearing loss and cognitive decline. Dr. Passerini notes that numerous studies have demonstrated an increased risk of cognitive impairment in individuals with untreated hearing loss. “When hearing is reduced, the brain has to work harder to decode sounds, and this continuous effort diverts resources from memory and attention,” he explains. This cognitive strain underscores the importance of addressing hearing issues promptly.
Hearing Loss Isn’t Just an Age-Related Issue
While age is a common factor in hearing loss, it’s not the only one. Dr. Passerini points to several other contributing factors, including noise exposure in the workplace, loud music, and even the employ of firearms. Medical conditions such as diabetes, cardiovascular problems, and recurrent ear infections can also increase the risk of hearing loss. Protecting hearing requires awareness of these diverse risk factors.
Newborn Hearing Screening: A Crucial First Step
Newborns in many countries, including Italy, undergo routine hearing screenings shortly after birth. While this is a vital step, Dr. Passerini clarifies that it’s not always sufficient to guarantee early diagnosis. The World Health Organization estimates that up to three out of every 1,000 newborns in Western countries are affected by hypoacusia (hearing loss). This incidence rises to 10-20 times higher in newborns with risk factors, such as a family history of infant hearing loss.
When a newborn fails the initial screening, Dr. Passerini explains, the case is referred to a regional hearing network. “Our neonatology and audiology departments are part of the regional hearing network,” he says. “We use software to analyze the screening results, identifying both false positives and false negatives, which are evaluated monthly. If hearing deficits persist, infants—with or without risk factors—are referred for rehabilitation at tertiary care centers.”
Recognizing Hearing Loss in School-Aged Children
Monitoring hearing health doesn’t complete after the newborn screening. Dr. Passerini stresses the importance of vigilance in school-aged children. Parents and teachers should be aware of potential warning signs, such as a child not responding when called, frequently asking for repetition, providing irrelevant answers, or consistently positioning themselves close to the sound source. A sudden decline in academic performance can also be an indicator. Early intervention is key to maximizing a child’s potential.
The Impact of Headphones and Volume Levels
The widespread use of headphones raises concerns about potential hearing damage. Dr. Passerini cautions that the risk depends on both the duration and volume of use. “The risk increases when the volume exceeds 60% of the maximum, or when listening for more than 60 consecutive minutes,” he explains. The damage, he emphasizes, is gradual but irreversible, affecting the sensory cells in the ear. Even brief exposure to very loud noises can cause temporary—and sometimes permanent—damage.
Modern Hearing Aids: Effective Solutions
Fortunately, modern hearing aids offer effective solutions for many types of hearing loss. Dr. Passerini explains that these devices go beyond simple amplification. “They don’t just amplify sound; they process it to improve speech comprehension, reducing background noise,” he says. “They are effective because they have significantly improved understanding, automatically adapt to noisy environments, and reduce whistling.” Current options include in-the-ear and behind-the-ear models, with the latter often recommended for more severe hearing loss. While hearing aids don’t cure hearing loss, they can dramatically improve a patient’s quality of life.
Protecting your hearing, and that of your children, is an investment in long-term health and well-being. Recognizing the early signs of hearing loss, understanding the associated risks, and seeking professional evaluation are crucial steps in maintaining auditory health. As Dr. Passerini’s work demonstrates, proactive care can produce a significant difference in preserving hearing and cognitive function throughout life.
The hospital continues to participate in the regional hearing network, constantly evaluating and refining screening processes to ensure the most accurate and timely diagnoses possible. Further research into the link between hearing loss and cognitive decline is ongoing, promising even more effective strategies for prevention and treatment in the future.
