Digital Dementia: Does Technology Use by ‘Digital Pioneers’ Correlate to Cognitive Decline?
As the first generation that interacted with digital technology reaches an age where dementia risks emerge, scientists have asked the question: Is there a correlation between digital technology use and an increased risk of dementia? With the phrases “brain rot” and “brain drain” circulating on social media, it would appear that most people would assume the answer is yes. However, a new study in Nature Human Behavior by neuroscientists at Baylor University and the University of Texas at Austin Dell Medical School reveals the opposite – digital technologies are actually associated with reduced cognitive decline. The study – A meta-analysis of technology use and cognitive aging – was sparked by the ongoing concern about the passive activity of digital technologies and their relation to accelerating risks of dementia. Study co-authors are Jared F. Benge, Ph.D., clinical neuropsychologist and associate professor of neurology at Dell Medical School and UT Health Austin’s Comprehensive Memory Center within the Mulva Clinic for the Neurosciences, and Michael K. Scullin, Ph.D., associate professor of psychology and neuroscience at Baylor. “You can flip on the news on just about any day and you’ll see people talking about how technologies are harming us,” Scullin said. “People often use the terms ‘brain drain’ and ‘brain rot,’ and now digital dementia is an emerging phrase. As researchers, we wanted to know if this was true.” The “digital dementia” hypothesis predicts that a lifetime of exposure to digital technology will worsen cognitive abilities. On the contrary, the study’s findings challenge this hypothesis, indicating instead that engagement with digital technology fosters cognitive resilience in these adults. Reviewing more than 136 studies with data that encompassed over 400,000 adults, and longitudinal studies with an average of 6 years of follow-up data, Scullin and Benge found compelling evidence that digital technology use is associated with better cognitive aging outcomes, rather than harm. The researchers’ study supported the “technological reserve” hypothesis, finding that digital technologies can promote behaviors that preserve cognition. In fact, their study revealed that digital technology use correlates with a 58% lower risk of cognitive impairment. This pattern of cognitive protection persisted when the researchers controlled for socioeconomic status, education, age, gender, baseline cognitive ability, social support, overall health, and engagement with mental activities like reading that might have explained the findings. Increase in problem-solving skills Scullin said that for some, these findings are surprising as technology use is often associated with being sedentary both physically and mentally. However, for the current generation of older adults who were introduced to the first technological advancements – computers, the Internet and smartphones – past their childhood, using technology is cognitively challenging because it is everchanging. “One of the first things that middle-age and older adults were saying is that ‘I’m so frustrated by this computer. This is hard to learn.’ That's actually a reflection of the cognitive challenge, which may be beneficial for the brain even if it doesn’t feel great in the moment.” Scullin said. Technology requires constant adaption, he said, such as understanding new software updates, troubleshooting Internet loss or filtering out website ads. “If you’re doing that for years and you’re really engaging with it, even though you might experience frustration, that may be a sign of you exercising your brain,” he said. Social connection Technology also enables communication and engagement like never before, which can expand opportunities for connectivity. Video calls, emails and messaging apps help maintain social networks, especially for people who would not otherwise regularly see their family members. “Now you can connect with families across generations,” Scullin said. “You not only can talk to them, you can see them. You can share pictures. You can exchange emails and it's all within a second or less. So that means there's a greater opportunity for decreasing loneliness.” Better social connectedness is a well-documented correlate of cognitive functioning in older adults, providing a link between decreased isolation from digital technologies and reduced risks of dementia. Impact of “digital scaffolding” A dementia diagnosis is indicated in part when cognitive changes lead to a loss of independence with daily tasks. Tools such as digital reminders, GPS navigation and online banking allow older adults to remain independent despite cognitive difficulties through digital scaffolding. According to the research article, this digital scaffold “facilitates better functional outcomes in older adults while general cognitive functioning declines.” Technologies can serve as a compensatory support system to maintain general independence and reduce the risk of a dementia diagnosis even with the presence of some cognitive decline. “As clinical practice continues to move toward an individualized, precision-medicine approach, it will be necessary for the field to identify for whom and for how long, such digital scaffolding is effective,” the researchers said. Promoting healthy technology use While Scullin recognizes the negative effects of technology, such as distracted driving or using technology over consistent face-to-face interaction, he also emphasizes how promoting a healthy use of digital tools in older adults is beneficial for their cognitive health. “If you have a parent or grandparent who’s just staying away from technology, maybe revisit that. Could they learn to use photo, messaging, or calendar apps on a smartphone or tablet? Start simple and be very patient while they learn,” he said. Social media use is another highly debated topic in terms of cognitive effects. While he says it’s hard to predict the cognitive effects of endlessly scrolling on TikTok, Scullin does argue that generating videos through creative cognition could be beneficial. In addition, he said that interacting with communities online can provide benefits by forming social connections. “We could spend a long time talking about all the specific ways in which technology use can be bad. However, the net effect since the 1990s has been positive for overall cognition in older adults,” he said. FUNDING The study was supported by funding from the National Institutes of Health (R01AG082783; M.K.S., J.F.B.).

Innovative EEG Brain Monitoring Program Provides Optimal Care for Critically Ill Patients
ChristianaCare has launched an innovative electroencephalogram (EEG) brain monitoring program that represents a significant leap forward in the diagnosis and management of neurological conditions. The easy-to-use EEG program is the first of its kind that can be performed at the bedside to measure the electrical activity of the brain, providing a vital sign for brain function to help diagnose seizures more quickly. ChristianaCare is the first hospital system in Delaware to use the Ceribell point-of-care EEG monitoring system, which can reduce the time it takes to diagnose certain neurological conditions from hours to mere minutes. Using the system, clinicians have immediate access to EEG information so they can triage at-risk patients in just five minutes and monitor patients for treatment optimization. “With this new program, our team of expert clinicians will have the diagnostic information they need to provide high-risk patients with the right care at the right time, ensuring the best outcomes for our patients and their families,” said Kim Gannon, M.D., Ph.D., service line leader for Neurosciences at ChristianaCare. New technology detects ‘silent seizures’ Critically ill patients are at high risk of harmful brain electrical discharges called seizures. Some of these patients experience a type of “silent seizure” with no noticeable symptoms (non-convulsive) that can only be detected using EEG. If prolonged, non-convulsive seizures can lead to permanent brain injury and higher risk of morbidity and mortality. Demonstration of EEG device on patient at ChristianaCare Newark Campus. As a result, guidelines from the Neurocritical Care Society recommend EEG should be initiated within 15-60 minutes when these seizures are suspected. Meeting these guidelines has proven difficult due to the limitations of conventional EEG systems, which were not designed for use in emergency situations. Even top academic centers that have 24/7 EEG capabilities may experience wait times of four hours or more for conventional equipment. When relying on clinical judgement alone while waiting for these conventional EEG systems, diagnostic accuracy has been shown to be only slightly better than chance (65%). The value of this new technology for patients is that it provides accurate results quickly so that the care team can intervene early. “The neuroscience and critical care teams at ChristianaCare believe that ‘time is brain’ not only applies to stroke but also when dealing with seizure,” Gannon said. Gannon is referring to the fact that for every minute that passes when someone is having a stroke, 1.9 million brain cells are lost, increasing the chance of disability or death. That same kind of speed and urgency can now more easily be brought to bear for patients when a seizure is suspected. “This monitoring system is easy to use and can be set up in about five minutes,” said Richard Choi, D.O., medical director of the Neurocritical Care Unit at Christiana Hospital. “It consists of a simple headband, pocket-sized recorder with intuitive software and an on-line portal for remote viewing. Using the system, we can review EEG data, assess response to treatment and optimize care, all in real-time.” Neurosciences at ChristianaCare ChristianaCare’s multidisciplinary neurosciences team provides comprehensive and advanced care for neurologic illnesses across the acute and ambulatory settings. As the largest and most comprehensive neurology practice in Delaware with more than 55,000 patient visits last year, ambulatory subspecialties include stroke, epilepsy, multiple sclerosis, movement disorders, neuromuscular disorders, headaches/migraines, pediatric neurology and Botox specialists. The inpatient team of experts includes neurosurgeons, neurointerventional surgeons, neurocritical care physicians and vascular neurologists. The Newark Campus serves as the only comprehensive stroke center in the state and includes the only Epilepsy Monitoring Unit in Delaware.
‘The surprise, and the up side, is that episodic memories from before the children’s treatment were spared,’ Baylor researcher says Children with certain types of brain tumors who undergo radiation treatment are less likely to recall the specifics of events they experienced after radiation than to remember pre-treatment happenings, according to a Baylor University study comparing them to children with healthy brains. The finding is significant because children after treatment had less volume in the hippocampus — a part of the brain that plays an important role in memory. But while such a decrease usually is associated Alzheimer’s disease, dementia, brain injury, epileptic amnesia, encephalitis and aging, with those conditions both remote and recent memories are impaired, said lead author Melanie Sekeres, Ph.D., director of Sekeres Memory Laboratory at Baylor University. “The surprise, and the up side, is that episodic memories from before the children’s treatment were spared,” Sekeres said. For the study, published in The Journal of Neuroscience, researchers focused on “autobiographical memory,” which is linked to unique personal events and involves the recollection of emotional and perceptual details that allow a person to mentally re-experience the event, said Sekeres, assistant professor of psychology and neuroscience in Baylor’s College of Arts & Sciences. Radiotherapy and chemotherapy are used to treat the most common malignant brain tumor in children — a medulloblastoma. The reduced volume of the hippocampus is likely associated with radiation’s impact on the development of new cells in the nervous system, including the growth of new neurons in the hippocampus, or neurogenesis. “We know that these new cells play crucial roles in regulating memory and spatial learning, which is required to navigate. These treatments limit the brain’s ability to produce these new cells, which, in turn, limits the ability to form new memories,” Sekeres said. Research participants were 13 child survivors of brain tumors who had previously received radiotherapy and chemotherapy treatment at least one year before the study. Twenty-eight healthy youths of similar ages (ranging from 7 to 18) also were recruited for the study, conducted with The Hospital for Sick Children in Toronto, Ontario, Canada. All the youths completed the Children’s Autobiographical Interview — a standardized memory test — and underwent magnetic resonance imaging (MRI) of the brain. In individual interviews, children in both groups also were asked to recall memories from personal events that occurred at a specific time and place. Children were asked to recall a very old memory from an event before their radiation treatment (or an equally old memory for the healthy children) and a recent memory from within the past month. They were offered a list of events such as a birthday party, family trip, graduation and getting a pet but were told that they could choose another happening. The interview allowed children to freely recall without prompting before being asked general and specific questions about the event. “They have a hard time forming new, detailed memories,” Sekeres said. For example, when talking about a recent birthday party for a friend, they might tell how they met the friend and what that individual likes to do, but few specifics such as what they wore, the type of cake, what friends were there and what activities they did at the party, she said. “Such specific details might seem trivial, but these are precisely the kinds of details that allow us to vividly replay important events in our lives,” Sekeres said. “For most events, though, even healthy people forget a lot of specific details over time because we typically don’t need to retain all that incidental information. Some forgetting is normal and adaptive, and what we remember is the gist of an older event.” The patients were just as capable as healthy children of recalling these older memories, she said. But for children with brain tumors who have undergone radiation, the study suggested “deficits in their ability to either encode and/or retrieve highly detailed memories for personal events,” Sekeres said. “And those are the kind of memories that allow us to understand who we are and give us rich personal lives. “The study identifies an area of cognition that is inadvertently impacted by standard treatment, which has real consequences for the quality of life of the survivors. The physicians’ ultimate goal is to allow their patients to survive and to live as well as possible,” Sekeres said. “Although these treatments are often crucial in the effective management of the cancer, if the physicians and the family know there are these unintended side effects, that may be an additional factor to consider when exploring the treatment options.” ABOUT THE STUDY The study — “Impaired recent, but preserved remote, autobiographical memory in pediatric brain tumor patients” — was conducted with the Brain Tumor Program and the Program in Neurosciences and Mental Health at The Hospital for Sick Children in Toronto, Ontario, Canada. Funding was provided through the Canadian Institutes of Health Research. ABOUT BAYLOR UNIVERSITY Baylor University is a private Christian University and a nationally ranked research institution.
