Can Social Media Help Maintain Senior Brains?
Why the Same Habit That Worries Families Might Also Be Protecting Their Senior Family Members
While in some cases seniors’ overuse of social media can be worrying for their families, the same habit could actually be having a protective function. This article sets out to explore the benefits of digital technologies for older people and to counter some of the myths. An obvious benefit of social media use is to reduce loneliness and form new connections. However, there is a greater benefit. New research on the use of technology by older people has revealed the existence of ‘technological reserve’, which boosts their ability to keep up with other people of all ages. In practical terms, the way an older person uses technologies such as social media has a significant impact on the positive benefits it offers. In particular, active use of social media (i.e. learning, participating, connecting etc.) can be very beneficial for older people, whereas ‘passive use’ (i.e. idly browsing or doomscrolling) is far less useful. In practice, passive use may even have a number of negative effects that are quite the opposite of what is intended.
The Three Kinds of "Social Media" Worth Distinguishing
By distinguishing between the different types of social media (e.g., Facebook, online games, messaging services, etc.) with their respective degrees of good and bad, it’s helpful to think about them separately.
I group the many different forms of social media into three categories. When many people hear the term “social media,” their first thought is of social networking sites Facebook, Instagram, YouTube, WhatsApp, and TikTok. But there are also many video conferencing and collaboration tools that allow you to have real-time communication with other people. The most popular of these for a casual chat with family and friends is probably FaceTime. And then there’s instant messaging, which allows real-time text messages to be sent and read on a phone, tablet or computer. A person who is hard of hearing may find text very easy to read and often easier than a phone call where they have to keep repeating “what?” until the person at the other end of the line ends up saying “it’s not important.” That was often the case when I had phone conversations with my hard-of-hearing mother.
Since each form of social media has a lot of good and bad in it, we decided to outline each of the different categories with examples and benefits.
Social Networking
Examples: Facebook, Instagram, YouTube, WhatsApp, TikTok
Primary Use: Connecting with friends, family, and people with shared interests
Main Benefit: Combats loneliness and isolation; helps people find new communities
Video conferencing
Examples: Zoom, MS Teams, Google Meet, FaceTime
Primary Use: Meetings with family, social groups, and educational organizations
Main Benefit: Continued learning and mental stimulation in a group setting
Messaging
Examples: Built into any phone, tablet, or computer
Primary Use: Fast, real-time conversation; sharing photos and updates
Main benefit: Simple, low-friction communication, especially useful for those with hearing loss
Taken together, the case for all three forms of social media is the same: they combat loneliness and isolation, support cognitive functioning, and give older adults a low-effort way to maintain connection with others and to keep learning new things.
What the Benefits Actually Look Like
The phrases that repeatedly show up in research abstracts are that social media usage "reduces loneliness" and "builds cognitive reserve." These somewhat overused terms can obscure what the benefit actually feels like day-to-day for an older adult who is using the technologies.
In addition to enjoying their grandkids’ photos, a parent who is no longer able to drive to a senior center, church, or work can join groups of retired professionals, trace three generations of their family genealogy, join book club discussions, or even find a new neighborhood center via online forums. The bottom line is that they can experience connection via these tools. With messaging apps, they can continue to have running conversations with friends and family, keeping their brain sharp and focused. These connections require very little in terms of going online, and can be as simple as joining one group, starting one thread or checking in with one person from time to time.
Using social media to read about current events is very different from watching old TV reruns. While favorite old sitcoms can be entertaining and stimulating to the brain in the short term, reading a news article is associated with real cognitive tasks - determining its meaning, forming an opinion, and deciding whether it is worthy of social conversation. Daily repetition of these tasks causes large amounts of information to be stored in long-term memory for later retrieval, weighing it against other information and forming opinions. Events of the day provide a way to feel connected to the world at large. A parent who reads current events on his phone or tablet has something to say to his grandchildren or to his children, and can bring up current events as a conversation topic, as opposed to speaking about his failing health.
Commenting on posts or even participating in online dialogues can be considered as real language exercises. Reading others’ comments, replying to them, even defending one’s own views in case of criticism involves selecting the right words, grasping the author’s tone, constructing arguments and more. While such activities meet real communicative needs of individuals, in particular of older adults, who often feel that their opinions are not being heard, they require mental juggling which is tested in the Facebook working-memory study below. This mental activity is good for one’s brain and, therefore, should not be reduced to mere commenting.
Learning new things to do might be the most underrated benefit to online social activities, since it does not look like ‘brain training’. Watching YouTube tutorials to fix a leaky faucet, following a birdwatching page and learning about new species every week, taking a free class offered through a library’s Facebook page, learning to use a new app to learn Spanish that you have always meant to study—these are all examples of novel, effortful mental activity that would be expected to have some cognitive benefits. A friend of mine is very fluent in French and Spanish, as well as in English. She said that she is currently following and watching French-speaking and Spanish-speaking online social media creators in order to keep up her language skills and not lose them. She said that she gets entertainment value from it as well, so she is entertained, engaged, and learning new things.
The Encouraging Research
The most interesting study I read recently about the effects of technology on the aging brain spoke to the concept of “technological reserve.” Similar to “cognitive reserve,” the idea is that some life experiences are better than others when it comes to preparing the brain to age. A huge meta-analysis published in Nature Human Behaviour studied the impact of technology on the brains of adults over 50 (the studies included ranged from 50 years old and up, with an average age of 68.7 years). In short, it found that those who use computers, smartphones, and the internet regularly experience slower decline in the cognitive functions of interest, and in some cases are less likely to experience cognitive impairment at all. It even found that technology can have similar or even greater benefits for the aging brain than more established methods of preserving cognitive function like exercise or education – a far cry from the long-discredited “digital dementia” concept that suggested that heavy use of technology would lead to the degradation of memory, attention, and other important cognitive functions as they are no longer engaged by the brain if technology takes their place.
However, more recent research has moved on from these theories. One study focused on the specific requirements that technology must meet in order to have a positive impact on the brain of older adults. The 54 participants in the study were all computer novices and averaged 74.6 years of age. They were randomly assigned to either an iPad training group, which received 15 hours per week of training over 3 months and used the iPad for 15 hours per week for 3 months, or they were assigned to a control group. There was a one-year follow-up on the measures of processing speed and of episodic memory. The results from the iPad group showed significant gains on measures of processing speed and of episodic memory, and these gains were found to still be in place one year later. This is clearly more meaningful for older adults who have little to no experience with computers, and who are cared for by their adult children.
The study from 2017, entitled “Facebook Training Improves Working Memory in Older Adults,” involved a group of seniors learning to use Facebook in an 8-week program, contrasted with another group creating an online diary over the same time span. What they found was that working memory, or the ability to keep several pieces of information and update them as necessary (i.e., to follow a conversation with several others or keep track of schedules), improved in the Facebook group but not in the online diary group. This was a small study, but it was a controlled one and found something real. The study didn’t report the specific ages of the participants, so it’s not clear how applicable this finding is to seniors of a particular age, or those who have already experienced significant mental decline. The key takeaway, though, is that the social and cognitive demands of the various online platforms are likely to be much more important than any feeling of pleasure or utility that people experience just by the mere act of being online.
Finally, the old story of the “digital divide,” whereby elderly adults are not tech-savvy, is passé; in the US 90% of adults 50+ use social media, and nearly half of them spend more than an hour per day on Facebook or YouTube alone.
The Real Risks
None of the touted benefits cancel out the genuine downsides, and caregivers are right to stay alert to them.
Overuse can undercut the very connection it promises. Natural changes in the prefrontal cortex as we age can make compulsive behavior harder to resist, and what starts as a way to see the grandkids' photos can slide into hours of YouTube autoplay or reflexive Facebook refreshing. Research has linked more than six hours of daily social media use in older adults to increased depression and anxiety, along with poorer sleep and more sedentary behavior. Fragmented attention, task-switching between messages, videos, games, and notifications, can also produce cognitive strain and crowd out protective habits like sustained, deep reading.
Misinformation is another distinct problem from information overload, and it's worth telling them apart. Overload is an attention and filtering problem: too much content arriving too fast. Misinformation is a deception problem: content deliberately designed to mislead. A parent overwhelmed by notifications needs different help than one who has shared a false health claim. Treating both problems the same way tends to help with neither.
Fraud is the biggest risk. Older adults are frequent targets for scammers posing as the Social Security Administration, Medicare agents, banking institutions, or family members in crisis. This is often done to extract personal information, remote access to a device, or money outright. This isn't hypothetical: roughly 1.3 million Medicare beneficiaries had their Medicare numbers compromised in a recent breach, and CMS has had to reissue new numbers and cards, which has itself created an opening for scammers to call claiming a need to "verify" the new number. Fake virus warnings, by email, text, or an unsolicited phone call, are another common front door, designed to get a senior to call a fraudulent number or grant remote access to their computer. The financial scale of this problem is larger than most families realize. The FTC estimates that fraud, including a large amount originating on social media through investment and romance scams, cost older Americans as much as $81.5 billion in 2024 alone, when they factor in underreported cases, against just $2.4 billion in losses actually reported to the agency. This is no laughing matter. Many seniors have shared that they receive fraudulent phone calls or emails every single day. We have several other articles that expand on this very topic. See “Why is a Nigerian Prince Calling Me.”
What Caregivers Can Actually Do
Instruct your parent on the following:
Never act on urgent demands made over the phone or in a pop-up computer message. Hang up or close it, and call a trusted family member or the organization's official number directly.
Never grant remote access to a computer or phone to an unsolicited caller or a warning pop-up, no matter how official it looks.
Set reasonable time expectations, not as a punishment, but so screen time doesn't quietly replace outdoor activity, in-person visits, or sleep. If your parent does not live with you, engage a caregiver to look in on your parent periodically
Teach digital safety directly: how to spot a fake account, how to block a stranger, and why personal information doesn't belong in a reply to an unsolicited message.
Encourage active engagement over passive scrolling: conversations, groups tied to real interests, video calls with people they know, rather than an endless autoplay feed.
Know where to send them if something goes wrong. The National Elder Fraud Hotline (833-372-8311) is staffed by the Department of Justice specifically for this.
Agency, Not Ageism
It's worth pushing back on an assumption that runs through a lot of the coverage of seniors and technology: that older adults are uniformly vulnerable, credulous, and in need of rescue. The research doesn't actually support treating age itself as the risk factor. Painting every older adult in the same light produces exactly the kind of generic, condescending "digital literacy" campaigns that talk at seniors instead of with them, and can miss the specific kind of help any individual actually needs. What matters far more is the quality of engagement. Purposeful use, communicating with people, learning something, joining a group tied to a real interest, looks protective. Compulsive, passive use is where the trouble tends to focus.
Technology solutions can make an enormous difference for those of us caring for elderly parents: keeping us connected to the world around us, actively engaged, and mentally stimulated. — Chapter 2, Survival Guide to Caring for Aging Parents
A Final Word
The honest version of this story isn't "social media is good for seniors" or "social media is dangerous for seniors." It's that the same behavior, whether it’s scrolling a feed or joining a video call, can point in either direction, depending on why someone is reaching for it, and hw they engage once there. The most useful thing you can do as a caregiver is to help build the habit of active, purposeful use, and to make sure the people you love know exactly who to call the moment something feels wrong.
