Introduction to Technology and Brain Benefits
The relationship between technology and brain health has been a topic of interest in recent years. While some research has suggested that excessive technology use can have negative effects on cognitive function, a new analysis has found that older adults who use technology regularly may actually experience cognitive benefits.

The Digital Pioneer Generation
Wanda Woods, a 67-year-old woman, is an example of someone who has been using technology for decades. She started with a high school typing course and has since learned to use various digital devices, including computers, smartphones, and the internet. Woods now works as an instructor with Senior Planet in Denver, an AARP-supported effort to help older people learn and stay abreast of technology.
Cognitive Benefits of Technology Use
Some neuroscientists researching the effects of technology on older adults have found that regular technology use is associated with reduced risk of cognitive impairment and dementia. Michael Scullin, a cognitive neuroscientist at Baylor University, notes that "among the digital pioneer generation, use of everyday digital technology has been associated with reduced risk of cognitive impairment and dementia." This finding is surprising, given the common perception that technology use can have negative effects on brain health.
Analysis of Technology Use and Cognitive Function
A recent analysis of 57 studies involving over 411,000 seniors found that those who used computers, smartphones, the internet, or a mix did better on cognitive tests, with lower rates of cognitive impairment or dementia diagnoses, than those who avoided technology or used it less often. The analysis, published in Nature Human Behavior, found that almost 90% of the studies showed a protective cognitive effect of technology use.
Theories Behind the Cognitive Benefits
There are several theories behind the cognitive benefits of technology use in older adults. One theory is that technology use provides a mental challenge, which can help build cognitive reserve and reduce the risk of cognitive decline. Another theory is that technology use can help foster social connections, which are known to be important for brain health. Additionally, technology can provide reminders and prompts, which can help compensate for memory loss and preserve functional abilities.
Limitations and Potential Risks
While the analysis suggests that technology use may have cognitive benefits, there are also potential risks to consider. For example, online fraud and scams often target older adults, and excessive technology use can lead to social isolation and decreased physical activity. Additionally, the analysis cannot determine causality, and it is possible that people with low cognitive ability may avoid technology use.
Conclusion
The relationship between technology and brain health is complex, and more research is needed to fully understand the effects of technology use on cognitive function. However, the analysis suggests that regular technology use may have cognitive benefits for older adults, and that it may be an important tool for building cognitive reserve and reducing the risk of cognitive decline.
FAQs
Q: What are the cognitive benefits of technology use in older adults?
A: Regular technology use has been associated with reduced risk of cognitive impairment and dementia, and may help build cognitive reserve and preserve functional abilities.
Q: What are the potential risks of technology use in older adults?
A: Potential risks include online fraud and scams, social isolation, and decreased physical activity.
Q: Can technology use help foster social connections in older adults?
A: Yes, technology can provide opportunities for social interaction and connection, which are important for brain health.
Q: How can older adults get started with technology use?
A: Older adults can start by taking a computer class or workshop, or by asking a family member or friend to teach them how to use a digital device.
Q: Is it ever too late to start using technology?
A: No, it’s never too late to start using technology, and many older adults have found that it has improved their quality of life and helped them stay connected with others.
