A new study published on April 15, 2025, reveals that using everyday digital technology—like smartphones, computers, and tablets—may actually protect brain health in older adults rather than harm it. Contrary to longstanding fears that reliance on digital devices contributes to cognitive decline, researchers found that these technologies may play a positive role in preserving memory and thinking skills. The study, conducted by scientists from the University of Texas at Austin and Baylor University, analyzed data from 57 prior studies, covering more than 411,000 adults with an average age of 69. It showed that those who regularly used digital technology had a 58% lower risk of developing cognitive impairments compared to those who did not.
The researchers argue that using digital devices can challenge the brain in meaningful ways. Tasks like reading news online, sending emails, using GPS, or managing a calendar require mental engagement and memory, helping to keep the brain active. These actions involve navigating apps, understanding icons, recalling passwords, and making decisions—cognitive processes that mirror many of the brain’s executive functions. In other words, regular interaction with technology may act like mental exercise, reinforcing cognitive skills much like physical activity helps maintain muscle strength.
One of the most notable aspects of the findings is how they contradict popular concerns about “digital dementia,” a term used in recent years to describe the belief that technology use causes memory problems by making people too reliant on external tools. Instead of supporting this idea, the researchers found the opposite: older adults who stayed digitally engaged were less likely to show signs of cognitive decline. This suggests that fears around the negative effects of digital tools on the aging brain may be overstated or even unfounded.
The researchers proposed three main reasons why digital technology may be beneficial: complexity, connection, and compensation. Complexity refers to the mental challenges posed by using technology, which can stimulate cognitive functions. Connection refers to the social aspect—staying in touch with family and friends through messaging, video calls, or social media—which has long been linked to better brain health. Compensation describes how digital tools can help older adults cope with minor memory issues, such as by setting reminders or keeping track of important information, reducing stress and promoting independence.
Experts outside the study also praised the results. Dr. Leah Mursaleen from Alzheimer’s Research UK said the findings were encouraging and aligned with what is already known about mental stimulation and brain health. Caroline Abrahams of Age UK emphasized that while the benefits of digital engagement are clear, some older adults still struggle with access or confidence using these tools. This underlines the importance of digital inclusion—ensuring all seniors have the opportunity, training, and support needed to benefit from the digital world.
The research carries significant implications as global populations continue to age and technology becomes further embedded in daily life. As more adults over 50 begin to age into their 70s and 80s with a lifetime of digital experience, understanding how to harness technology to support mental health will be increasingly important. While the study does not suggest that tech use alone is a magic bullet against dementia, it does point to a relatively simple, low-cost, and accessible way to help preserve cognitive function over time.
In summary, the study challenges outdated assumptions that technology is harmful to older minds and instead presents a hopeful narrative: when used actively and meaningfully, digital technology can support brain health, improve quality of life, and help older adults stay mentally sharp. As researchers continue to explore the intersection of aging and technology, these findings offer strong evidence that staying digitally engaged may be one of the easiest and most effective tools for protecting cognitive function later in life.

Retiring Early? Your Health Coverage Strategy Just Became Mission-Critical
Suppose youre an early retiree living on a fixed income. In that case, 2026 brings confirmed changes you need to understandespecially around staying under the 400% Federal Poverty Level (FPL) to maintain ACA premium subsidies.The Two Key Updates:Enhanced ACA tax credits will expire after 2025.Congress has now passed legislation letting the expanded premium tax credits (originating in the American Rescue Plan and extended by the Inflation Reduction Act) lapse beginning in 2026.The subsidy cliff returns in 2026. With enhanced credits eliminated, the traditional cutoff at 400% FPL is reinstated, and crossing that threshold could result in the loss of all subsidy eligibility, leading to significant premium increases. What Early Retirees Should Know On-Exchange (Marketplace) Plans:Subsidy eligibility will once again be limited to households at or below 400% FPL. Exceeding that income level in 2026 could mean losing all premium assistance and facing significantly higher costs.Off-Exchange Plans:These are direct-to-carrier, full-price planswith no subsidies or Marketplace involvement. Silver options might offer better pricing directly through the carrier than on the Marketplace.Consider Smart Income Planning:To retain subsidies, many early retirees are working with both their broker and financial advisor to manage how income is recognized throughout the yearsuch as timing withdrawals or shifting income sourcesto remain under the 400% FPL threshold.This is not financial advicejust a reminder to consult trusted professionals. Aligning your retirement income strategy with your healthcare needs can help maintain premium support until you become eligible for Medicare.Why It Matters:Exceeding 400% FPL in 2026 could result in hundreds of dollars more per month in premiums.With no Medicare yet, coverage costs could remain high for years.Thoughtful income planning now can preserve subsidies during your critical early retirement years.Final Thoughts:As an early retiree, planning is essential. Your health coverage and income are deeply interconnected, primarily through 2026 and beyond.To navigate these changes successfully:-Consult both your financial advisor and your health insurance broker-Monitor your FPL percentage annually.-Strategize income timing and coverage decisions together.

Providing Living Assistance without Intruding
If you or a loved one needs more hands-on care, living assistance can help put your mind at ease. Living assistance is flexible, personalized, and fosters a safe home environment while maintaining a sense of independence and privacy. It can give you or your loved one the freedom to make everyday choices and receive a helping hand whenever needed.At St. Barnabas, we understand that the transition from full to partial independence isnt easy and how important it is to ensure your needs and preferences are both addressed. Here are a few ways living assistance is provided without intruding.Receiving Help As NeededEncouraging independence is one way to foster non-intrusive assistance. At a senior living assistance campus, the staff is always available to lend a hand without eliminating decision-making. You or your loved one can retain a sense of autonomy by participating in the daily tasks and chores and receiving help on an as-needed basis. Intervention comes in varying degrees, depending on individual ability. A personalized care plan may include: Incontinence support Wheelchair assistance Medication management Help with grooming, dressing, and bathing Wound, ostomy, or catheter care Care staff is attentive and sensitive to your needs, and they can offer a little help throughout the day or when needed. By participating in daily activities, you or your loved one can plan your day based on your personal preferences.Collaborative SchedulingAs an alternative to making a pre-set schedule and asking the resident to stick to it, working together to create a personal care plan that suits everyone can be beneficial. When it comes to weekly meals, exercise routines, and social activities, residents have the freedom to choose. Maybe they enjoy hearty, home-cooked meals, or perhaps they like to do stretching exercises versus walks. Wherever passions lie, the staff can incorporate those into the regular daily routine to help encourage healthy living and socialization in ways that suit personal preferences.Collaborating with staff can also ensure that activities are both enjoyable and safe. When a resident cant do an activity they love, the team can work with them to find ways to feel that same sense of joy without putting them in danger.Respecting Boundaries and Private SpacesSpending time alone gives us a chance to relax, decompress, and gather our thoughts. In a living assistance care center, its imperative that residents still have some time for themselves. Caregivers respect boundaries and private spaces. Before entering a room, they knock on the door and wait for the resident to respond. Designating a private area for residents to turn to when they feel overwhelmed also aids in creating independence and ultimately gives them a space to de-stress and unwind.Places like the bathroom or shower are understandably uncomfortable areas for intrusion, so caregivers are sure to give residents the space they need to complete these tasks in private. The staff still makes sure the resident is safe by remaining nearby and listening for signs that something may be wrong.
