The FDA recently approved Apple’s AirPods Pro 2 for use as over-the-counter hearing aids, and it’s a breakthrough that could revolutionize how we address hearing loss and brain health. Designed for those with mild to moderate hearing loss, these earbuds combine cutting-edge technology with accessibility, offering personalized sound amplification, built-in hearing tests, and real-time noise protection—all in a device many people already use daily.
This innovation is more than just convenient; it’s a critical step forward in Alzheimer’s prevention. Untreated hearing loss is one of the largest modifiable risk factors for cognitive decline, and early intervention can play a powerful role in protecting brain health.
As a longevity physician specializing in brain health, this topic hits close to home for Dr. Scott Noorda. His father passed away from Alzheimer’s disease, and his age-related hearing loss was a significant contributor to his cognitive decline. Watching his journey fueled Dr. Noorda’s passion for helping others understand the vital link between hearing loss and brain health—and why addressing it early is key.
Why Hearing Loss and Alzheimer’s Are Linked
Hearing loss isn’t just about your ears—it has a profound impact on your brain. Here’s why:
- Reduced Brain Stimulation
Your ears provide a constant stream of sound signals to your brain. When hearing declines, this stream slows, depriving the brain of the auditory input it relies on to stay sharp. Over time, the parts of the brain responsible for processing sound may shrink, leading to brain atrophy—a precursor to cognitive decline. - Cognitive Overload
Straining to hear puts a heavy load on your brain. It has to work overtime to fill in gaps in conversations, leaving less mental energy for memory and problem-solving. This ongoing effort, called cognitive overload, accelerates mental fatigue and can increase the risk of Alzheimer’s. - Social Isolation
Hearing loss often leads to frustration in social settings, causing people to withdraw from conversations or avoid gatherings altogether. This isolation deprives the brain of social stimulation, which is essential for maintaining cognitive health. - Biological Links
Emerging research suggests a connection between sensory loss—like hearing impairment—and the biological processes that drive Alzheimer’s, including inflammation and oxidative stress.
Why Early Intervention Matters
Age-related hearing loss affects nearly one-third of people over 65, but the average person waits 7–10 years after noticing symptoms before seeking treatment. During this delay, the brain suffers from reduced stimulation, increased cognitive load, and diminished social engagement—all of which accelerate cognitive decline.
The good news? Intervening early can slow or even prevent this process. Hearing aids, cochlear implants, or even devices like the AirPods Pro 2 can preserve brain function by ensuring the auditory system continues sending signals to the brain.
A study published in The Lancet identified hearing loss as the largest modifiable risk factor for dementia. By addressing it early, you’re not just preserving your hearing—you’re taking proactive steps to protect your brain health and reduce the risk of Alzheimer’s.
How AirPods Pro 2 Fit Into the Solution
Apple’s AirPods Pro 2 are a practical and accessible option for addressing mild to moderate hearing loss. Here’s why they’re a game-changer:
- Built-In Hearing Tests
The AirPods Pro 2 can assess your hearing in real time, making it easy to monitor changes without visiting a clinic. - Personalized Amplification
These earbuds tailor sound amplification to your unique needs, helping you hear conversations and sounds more clearly without overamplifying. - Noise Protection
Real-time noise cancellation protects your ears from excessive background noise, ensuring a more comfortable and focused listening experience. - Cost-Effective and Stigma-Free
At a fraction of the cost of traditional hearing aids, the AirPods Pro 2 make hearing support more accessible. Plus, their discreet design minimizes the stigma often associated with hearing aids.
What Are the Risks?
While the AirPods Pro 2 offer incredible benefits, it’s important to consider the potential downsides:
- Delaying Professional Care
Relying solely on AirPods might prevent some individuals from seeking professional evaluation, delaying treatment for more severe hearing issues. - Improper Settings
Incorrect sound amplification could either under- or overcompensate for hearing loss, potentially causing further damage or discomfort. - EMF Exposure
Some people are concerned about long-term exposure to electromagnetic fields (EMFs) from wireless devices, although evidence of harm is still inconclusive.
Take Control of Your Hearing and Brain Health Today
The approval of AirPods Pro 2 as over-the-counter hearing aids is a significant step forward in making hearing care accessible to all. By catching hearing loss early and taking action, you’re not just improving your ability to hear—you’re protecting your brain, preserving your cognitive health, and reducing your risk of Alzheimer’s.
If you or a loved one has noticed changes in hearing, consider this: devices like AirPods Pro 2 can be a simple and effective first step. But remember, regular monitoring and professional evaluation are key to long-term hearing and brain health.
