Can spending too much time on screens lead to ‘digital dementia’? Ways to reduce the risk
As digital dependency increases, “digital dementia” emerges as a worrying problem, with studies indicating that excessive screen time can lead to cognitive decline. Research highlights the risks of passive digital activities. We have listed some ways to reduce the risk of digital dementia. Read on to know more.

In today’s fast-paced world, digital devices have become an integral part of our lives. Whether it is communication, work or entertainment, we are becoming more dependent on technology in our daily lives. However, as our dependence on these devices increases, it is important to recognize the potential risks they pose to our cognitive health. Research suggests that excessive use of technology can lead to changes in the brain, such as Madness And your risk of developing this condition may also increase.
Word “Digital Dementia“The term was first introduced by German neuroscientist Manfred Spitzer in 2012 to describe the decline of cognitive abilities in young adults and children who use digital technology excessively.
Cognitive impairment and brain function
Research has shown that excessive use of digital devices can have a significant impact on brain function and behavior. A 2022 study published in JAMA Neurology examined the relationship between sedentary activities, such as watching television and using a computer, and the risk of developing dementia. The study included more than 140,000 participants aged 60 and older, and found that spending more time in cognitively sedentary activities such as watching TV increased the risk of dementia, regardless of physical activity levels.

The study showed that engaging in passive cognitively active activities, such as using a computer, was associated with a reduced risk of dementia. This finding suggests that the type of digital activity plays an important role in determining its impact on cognitive health. While passive activities such as watching TV may contribute to cognitive decline, more interactive digital activities, such as computer-related activities, may offer some protection against dementia.
The role of technology in cognitive decline
The connection between technology use and cognitive decline is further corroborated by studies examining the effects of multitasking and information overload. A 2020 study published in Nature Communications found that people who frequently switch between digital tasks, such as checking email, browsing social media, and responding to messages, experience a decline in cognitive control and working memory. The constant bombardment of information can overwhelm the brain, leading to a shortened attention span, reduced problem-solving ability, and impaired memory formation.
Excessive Screen Time Screen time is associated with changes in brain structure. A study conducted by the National Institutes of Health (NIH) found that children who spent more than seven hours a day on screens showed premature thinning in the brain’s cortex, the area responsible for processing information from the senses. This thinning is a hallmark of cognitive decline and is often seen in people with dementia.
Tips to prevent digital dementia
Understanding the risks associated with digital device use is the first step to reducing its impact on cognitive health. People can adopt several strategies to protect their brain functioning:
Limit screen time: Set daily limits and take regular breaks from digital devices to prevent cognitive overload.
Engage in cognitive activities: Do tasks that challenge your brain, like reading, solving puzzles, or creative projects.
Practice mindfulness: Incorporate mindfulness techniques like meditation and focused breathing to improve focus and reduce multitasking.
Encourage real-life interactions: Prioritize face-to-face social interactions to maintain cognitive and emotional health.
Be physically active: Regular exercise boosts brain function and reduces the risk of cognitive decline.
Maintain a healthy sleep routine: Make sure you get enough sleep, as it is important for memory consolidation and overall health. Brain Health,
