When Technology Becomes a “Culprit” Behind Memory Loss

As younger generations increasingly depend on smart devices, a growing phenomenon known as “digital dementia” is emerging—with symptoms that resemble early-stage memory loss. A new term, “Young-Alzheimer,” has even been coined to describe this trend. So how can we prevent this modern health threat? H PLUS International Medical Center explores practical solutions in the article below.

What is tech-induced forgetfulness?

According to the “Popular Mobile Apps Among Vietnamese 2023” report by Q&Me, Vietnamese users spend an average of 6.2 hours per day on smartphones. Among those aged 18 to 29, over 51% spend more than 3 hours daily on social media.

With increased digital device use, people in their 20s and 30s are experiencing memory decline, reduced concentration, and cognitive disturbances. If left unchecked, these symptoms may progress to neurodegenerative conditions such as early-onset dementia.

Digital dementia is becoming especially common among young people due to heavy reliance on smartphones, laptops, and other electronics. As these devices begin to replace the brain’s memory function, they contribute to forgetfulness. Many young adults pride themselves on multitasking, yet this behavior increases the risk of memory loss. Using multiple devices at once—such as scrolling on your phone while watching TV—can impair short-term memory and attention span.

Students and office workers, especially those preparing for high-stakes exams, are frequently exposed to high stress levels. Chronic stress elevates cortisol levels, which negatively impacts memory and focus. Additionally, excessive alcohol consumption can damage brain function, and frequent intoxication may lead to permanent memory loss and even dementia.

Dr. Ryu Chang-hwan, a neurologist at H Plus Yangji Hospital, expressed concern:
“With digital technology, we now rely on devices to store important information—like phone numbers and birthdays—rather than memorizing them ourselves. This shift means we’re using our brains less for memory, and as a result, symptoms similar to dementia are appearing. Factors like stress from work, school, and social relationships also contribute to memory decline.”

10 signs of memory loss caused by technology overuse

If you experience two or more of the following signs, you may be suffering from tech-related memory loss:

• You primarily communicate via messaging or email instead of face-to-face conversations

• People often tell you that you repeat yourself in conversation

• You only remember your work and home phone numbers

• You can’t recall what you ate yesterday

• You’ve completely replaced paper maps with GPS navigation

• You can’t sing your favorite song without reading the lyrics

• You rarely write anything by hand except your signature

• You think you’re meeting someone for the first time but have actually met them before

• You often forget the meanings of words you once knew

• You sometimes forget your own family members’ phone numbers

How to prevent memory decline from digital device use

If digital dementia becomes chronic, it can lead to worsening memory and cognitive decline, potentially progressing to clinical dementia.

Prevention is the key. Limit unnecessary device use and organize your tasks and daily life in a mindful, structured way. One effective strategy is “digital detox,” where you set screen-time limits for each device—and strictly follow them.

In South Korea, a public initiative known as “1.1.1” launched by the Seoul city government encourages people to turn off their smartphones for one hour each week to reduce tech dependence. Healthy habits such as getting enough sleep, exercising, and taking regular breaks can also stimulate and protect brain function. In addition, prioritizing real-world interactions—such as meeting friends or joining clubs—over social media is highly beneficial.

Don’t forget to nourish your brain with healthy foods such as fruits, vegetables, nuts, and fatty fish. These provide essential omega-3 fatty acids, which help prevent cognitive decline.

Dr. Ryu Chang-hwan recommends:
“Develop the habit of writing notes by hand instead of typing on your phone. Activities like reading, playing musical instruments, journaling, chess, or board games stimulate the brain and can help improve memory. If you frequently forget important things or struggle to retain information, consider seeking professional neurological evaluation.”
