Using A Smartphone Can Cause Structural Differences In Your Brain – New Study
By Arjun Walia
- The Facts: A new study recently published by German researchers from Heidelberg University show differences in brain structure between people with ‘smartphone addition’ compared to people without it.
- Reflect On: Is your child constantly on their smartphone? Are they addicted?
Children entering into the world today are being birthed into a sea of technology that their parents never grew up with. As a result, we don’t really know the long-term consequences these technologies could have on these generations as they age. Preliminary research, however, is already showing significant cause for concern, and one of the latest examples comes from a study published in the journal Addictive Behaviors via German researchers.

The researchers examined 48 participants using MRI imaging, and 22 of the participants had smartphone addiction (SPA), and 26 of them were non-addicts. The main findings were that individuals with SPA showed “significant lower” grey matter volume (GMA) in the insula and in certain regions of the temporal cortex compared to the individuals without smartphone addiction, known as the controls. Secondly, right anterior cingulate cortex (ACC) activity was “significantly lower” in individuals with SPA compared to controls. Third, the researchers found associations between the smartphone addiction inventory (SPAI) scores and GMV as well as amplitude of low frequency fluctuations (ALFF), converged on the ACC.
The authors wrote that:
The present study provides first evidence for common neural underpinning mechanisms of behavioral addiction in individuals with SPA. This study clearly needs replication as much as extension in larger cohorts, including longitudinal assessments, ecological momentary assessment and task-based functional MRI. Yet, at the same time, this study provides important data and preliminary evidence, suggesting addiction-related differences in neural processes in the context of smartphone use, particularly with respect to the salience network. Given the widespread use and increasing popularity of smartphones, the present study challenges assumptions towards the harmlessness of smartphones, at least in individuals that may be at increased risk for developing addictive behaviors.
It should be concerning that there are actual structural changes in the brain that correlate with smartphone use in individuals who have an addiction compared to the brains of those who don’t.

The study goes into what each brain region is associated with in regards to behaviour, intelligence, etc.
In China, for example, teenagers are becoming hooked on electronic screens. Whether it be with their phone, computer, or video games, many young people are spending countless hours in front of a screen without bothering to eat or sleep, sometimes even withholding their urge to use the bathroom.
According to a blog report published by the New York Times, “many have come to view the real world as fake.” (source)
In China, this phenomenon is actually considered a clinical disorder, and as a result a number of rehabilitation centres have been established where young people addicted to screens are completely isolated from all media. Although the success of these treatment centres is still unknown, it paints a dark picture of the technological age in which we live, and does not seem to bode well for our future.
Studies in China show that people who spend more than 6 hours on the internet for something other than work or study are likely to become addicted. Below is a trailer for the documentary Web Junkies, shedding light on this troubling aspect of modern life:
It’s not just China, this type of thing is seen all around the world:
While Internet addiction is not yet considered a clinical diagnosis here, there’s no question that American youths are plugged in and tuned out of ‘live’ action for many more hours of the day than experts consider healthy for normal development. And it starts early, often with preverbal toddlers handed their parents’ cellphones and tablets to entertain themselves when they should be observing the world around them and interacting with their caregivers.

As we continue to move forward, this type of addiction and behaviour becomes more disturbing. The power that some multinational corporations have, alongside their clever marketing tactics – basically making whatever product or idea they choose to be desirable to the human mind – is worrisome. A few years ago, the American Academy of Pediatrics found that the average 8-10 year old spends almost eight hours a day with a variety of different media, and older children/teenagers spend even more, up to 11 hours.

A study conducted by the Massachusetts Aggression Reduction Center, which included over 20,000 children/teens between grades 3 and 12, concluded that approximately 20% of grade 3 students already owned a cell phone. The numbers steadily rose from that point forward to approximately 25% in grade 4, 39% in grade 5, and 83% in middle school. You can read that entire study HERE.
With all of these electronics, it’s important to be aware of the impact of the radiation they give out and their documented harms. To learn more about that and access the science now available, please visit the Environmental Health Trust. It’s a great place to start your research.
The Takeaway
We are in the beginning stages of what could potentially be a big problem. We have yet to see the smartphone generation reach adulthood; therefore, we can’t fully measure the potential consequences. But, again, numerous studies like this one have already shown great cause for concern and render the idea that smartphones are completely harmless as completely false.
Are we using our technological development in the correct ways?
