Here's what the research says, in plain language. 71% The 2025 Framingham Heart Study followed 2,100 people for 15 years. Untreated hearing loss — even mild — raised the risk of developing dementia by 71% compared to normal hearing. Brain MRI scans showed smaller brain volumes and damaged white matter in participants with untreated hearing loss. Recognizing Hearing Loss ## Do any of these sound familiar? If two or more feel true, a baseline hearing evaluation is worth your time. Sooner is easier — and outcomes are better. 1. 01 People sound like they're mumbling 2. 02 You contribute less at meetings, restaurants, or family gatherings 3. 03 The TV volume keeps climbing 4. 04 Background noise makes conversation exhausting 5. 05 You miss key words and lose the thread 6. 06 The phone is harder than it used to be 7. 07 You ask people to repeat themselves — often Effects of Untreated Hearing Loss ## The cost of waiting is bigger than most people think. ### Social isolation Withdrawing from conversation, gatherings, and the people you love. ### Listening fatigue Your brain works overtime to fill the gaps — and there's less left for everything else. ### Anxiety & depression Untreated hearing loss is linked with real declines in emotional well-being. ### Cognitive decline Framingham found a 71% higher dementia risk with untreated hearing loss. Good news Our brains are plastic. Treating hearing loss _changes the trajectory._ Wearing hearing aids about **12 hours a day** has been shown to reduce the risk of dementia. Hearing loss is the **number one modifiable** risk factor for cognitive decline — and that's a hopeful sentence. Your First Visit ## What to expect. 01 ### Case history A conversation.
