Yes, struggling with technology can be an early warning sign of cognitive impairment and dementia. When someone who once navigated smartphones, email, and familiar programs with ease suddenly finds themselves unable to remember passwords, confused by simple app updates, or frustrated by devices they’ve used for years, it may indicate underlying cognitive changes. This shift from technological competence to confusion is taken seriously by neurologists and the Alzheimer’s Association as one of the meaningful changes that warrant medical evaluation. However, a surprising twist emerged from recent research: the real story about technology and dementia is more nuanced than it first appears.
While struggling with technology can indeed be a red flag, using technology regularly is actually protective against cognitive decline. A 2025 meta-analysis published in Nature Human Behaviour found that digital technology use correlates with a 58% lower risk of cognitive impairment—suggesting that people who embrace technology may actually be protecting their brains from decline, not harming them. This contradiction matters because it clarifies what we should actually be monitoring: not the existence of technology in someone’s life, but rather whether someone is experiencing a sudden, unexplained decline in their ability to use tools they once understood. Understanding this difference helps families and healthcare providers identify genuine warning signs without unnecessary alarm.

What Changes in Technology Use Can Signal Cognitive Decline?
When cognitive impairment begins, it often shows up first in the tools we use every day. People with early dementia frequently struggle with memory-related aspects of technology: they may forget the password they’ve entered hundreds of times, lose track of which apps do what, or become confused by software updates that rearrange familiar icons. Beyond memory, they might struggle with the sequencing required for multi-step tasks—like attaching a photo to an email, navigating through menus, or following online conversations that require tracking context and details. The Alzheimer’s Association recognizes that technology difficulties are an extension of broader cognitive changes: difficulty concentrating, taking longer to complete familiar tasks, and trouble following conversations.
A person with emerging cognitive impairment might repeatedly ask the same questions during email exchanges, struggle to understand text messages, or become frustrated because they can’t track the logic of a website’s layout. These aren’t personality quirks or normal aging—they represent a measurable change in how the brain processes information and sequences actions. What matters clinically is the *change*. A 75-year-old who has never been tech-savvy isn’t showing a warning sign. A 68-year-old who once ran spreadsheets for work and suddenly can’t figure out how to open email attachments—that represents a meaningful shift worth investigating with a healthcare provider.
The Surprising 2025 Research: Why Technology Use Protects the Brain
The most important recent finding about technology and dementia came from researchers at Baylor University and UT Austin, who conducted a comprehensive meta-analysis of studies examining digital technology use and cognitive health. Their conclusion contradicts the widespread “digital dementia” hypothesis: people who regularly use digital technology show a 58% lower risk of cognitive impairment compared to those who don’t. This isn’t a small effect—it’s a dramatic protective association. The research examined what researchers call “digital pioneers”—people who adopted and regularly use digital technology. Rather than finding that screen time damages their cognition, the data showed the opposite.
Regular technology use appears to engage cognitive functions in ways that build cognitive reserve, strengthen neural pathways, and may help the brain resist decline. This aligns with other research showing that cognitively stimulating activities—learning new skills, solving problems, engaging in complex thinking—protect against dementia risk. The limitation here is important: this research shows correlation, not causation. It’s likely that people with better cognitive function are *more able* to learn and use technology, rather than technology use alone being protective. People who are already experiencing cognitive decline may naturally withdraw from technology because it becomes frustrating, creating a correlation that runs in the opposite direction. Additionally, this research doesn’t tell us whether all types of technology use are equally protective or whether some forms (learning a new platform, for example) are more beneficial than passive consumption (scrolling social media).
Specific Technology Struggles That Warrant Attention
When evaluating whether someone’s technology difficulties represent a warning sign, pay attention to specific patterns. A concerning sign is when someone repeatedly forgets how to access information they looked up the day before—not just struggling once, but showing a persistent pattern of lost learning. Another red flag is when someone who previously managed their own finances suddenly becomes unable to navigate online banking, read statements, or understand transaction confirmations. Communication technology struggles are particularly notable. Email confusion—not understanding new messages, repeatedly asking questions already answered, difficulty composing replies—can indicate the early stages of cognitive impairment.
Video call confusion (not knowing how to answer a call or unmute themselves) especially matters because it isolates vulnerable people from social connection exactly when they need it most. A person with emerging dementia might also become unable to manage their own medication reminders, set appointments in a calendar app, or use a smartphone’s built-in safety features like emergency contacts. The key distinction is between struggling with new technology versus losing competence with familiar technology. Everyone struggles when learning something genuinely new. But losing the ability to use a smartphone model you’ve owned for two years, or forgetting how to access email you’ve checked daily for a decade—that represents memory or cognitive processing changes that deserve professional attention.
How to Tell If Technology Struggles Are a Real Concern or Normal Aging
Not every technology frustration signals dementia. Many people in their 60s, 70s, and beyond find certain technology genuinely complicated, not because of cognitive decline but because the design is poor or they simply never learned that particular skill. The difference lies in whether someone is experiencing a noticeable *change* from their own baseline. Ask yourself these questions: Did this person used to be able to do this task? How recently did they do it successfully? Is the struggle consistent, or was it a one-time confusion? The most telling sign is whether the person themselves notices and is bothered by the change.
Someone with mild cognitive impairment often recognizes that their capabilities are slipping—they might say things like “I can’t remember my password anymore, I know I’ve used this one for years,” or “I keep forgetting how to get to my email.” This self-awareness of decline is often more significant than the specific task failure. There’s also an important tradeoff in how we approach this: if we’re too quick to attribute all technology struggles to dementia, we may cause unnecessary alarm and undermine confidence. If we dismiss them too readily, we miss genuine warning signs. The middle ground is to notice patterns, give it a timeline of months, and involve a healthcare provider when the changes seem consistent and concerning.
Important Limitations and What Experts Don’t Yet Fully Understand
While technology struggles can be a red flag, they’re neither a diagnosis nor something that appears in isolation. The Alzheimer’s Association emphasizes that the 10 warning signs—including technology difficulties—are meaningful only when they represent a change and when they interfere with daily life. A single instance of forgotten memory means very little; a pattern sustained over weeks or months is more significant. Additionally, many conditions other than dementia can cause technology struggles: vision problems, hearing loss, arthritis affecting hand coordination, untreated depression, medication side effects, or simple lack of familiarity. One critical limitation is that we don’t yet know whether the protective benefit of technology use applies equally across all populations.
Most dementia research involves predominantly white, educated populations. Whether technology engagement provides the same cognitive protection for people with less education, less access to technology, or different cultural approaches to digital tools remains understudied. Additionally, quality matters: passive scrolling through social media may have different cognitive effects than actively learning a new skill or engaging in digital problem-solving. Healthcare providers also note that the relationship between technology and cognitive health isn’t just about protecting the brain—it’s about quality of life. Even if technology use is protective, losing the ability to use devices can profoundly isolate someone from family, healthcare, and independence at the exact moment they most need support and connection.
Supporting Someone Struggling With Technology
If you notice that a family member or friend is genuinely struggling with technology they once understood, the practical first step is a conversation—not an intervention. Ask what’s frustrating them, where the confusion starts, whether they’ve noticed this change themselves. Sometimes the struggle is environmental (the technology genuinely did change due to an update) rather than cognitive. A simple explanation or demonstration might resolve it.
When technology struggles do reflect cognitive changes, the response is to both address the immediate frustration and create safeguards. This might mean helping someone move to a simpler phone, removing apps that confuse them while keeping the essential ones, or setting up features like automatic bill payment, one-touch calling, or simplified interfaces designed for reduced cognitive demand. At the same time, encourage any technology engagement that doesn’t cause frustration—if someone enjoys video calls with grandchildren, that engagement is actually protective. The goal is to maintain cognitive stimulation while removing unnecessary obstacles that might accelerate withdrawal from technology altogether.
What Technology’s Relationship to Brain Health Tells Us About Dementia Prevention
The 2025 research about technology’s protective effect points to a broader principle in dementia prevention: cognitive engagement matters more than cognitive decline fears matter. The people at lowest risk of dementia are those who continue learning, problem-solving, and engaging with complex tasks throughout their lives. Technology is just one avenue for that engagement; reading, conversation, games, travel, and new skill-learning all offer similar protection.
The brain, like a muscle, appears to strengthen with use and atrophy with disuse. This reframes how we should think about technology struggles as a warning sign: not as evidence that technology itself is dangerous, but as evidence that something is interfering with the brain’s ability to process and learn. It’s the interference that matters, not the medium. As our world becomes increasingly digital, the practical implication is clear: supporting people in learning and maintaining technology skills isn’t frivolous—it’s one of the most concrete things we can do to protect brain health and independence.
Conclusion
Technology struggles can indeed be an early warning sign of cognitive decline and dementia, particularly when they represent a change from someone’s previous abilities or interfere with their daily functioning. These changes deserve attention, evaluation, and conversation with healthcare providers, especially when accompanied by other cognitive changes like memory problems, difficulty following conversations, or increasing confusion. At the same time, the latest research reminds us that the relationship between technology and brain health is complex and ultimately protective.
The struggle itself matters, but so does the need to maintain engagement, learning, and cognitive challenge throughout life. Rather than fearing technology, the evidence suggests we should focus on ensuring that older adults can continue learning and using these tools, because doing so is one of the most concrete ways to protect the brain against decline. If you notice technology struggles in yourself or someone you care for, take them seriously as a sign worth investigating—not because technology is the problem, but because understanding the underlying cause might uncover something important about brain health.
