Smartphone Addiction and Brain Imbalances

We have all been thinking it. Smartphone addiction is a real problem and is taking a toll on addicted teens. In a recent study by the Pew Research Center, they found that 46% of Americans claim that they wouldn’t be able to live without their smartphone (I am definitely guilty of thinking this on a daily basis).
 This addiction was observed by Hyung Suk Seo, M.D, a professor of neuroradiology, in Seoul, South Korea using magnetic resonance spectroscopy (MRS) which is another form of MRI. Using a series of tests, Dr. Seo’s team categorized the teens addictions. The teens who scored highest in addiction also scored higher on tests examining depression, anxiety, insomnia, severity, and impulsivity.
The MRS was used to look at levels of GABA and Glx which are neurotransmitters in the brain that inhibits brain signals and one that acts on neurons to become more excited respectively. Imbalances in these neurotransmitters has been linked to mood disorders like depression and anxiety. The results showed an increased ratio of GABA to Glx in the anterior cingulate cortex in the addicted teens compared to the control teens.  
The team believes that cognitive and emotional control is hindered by increased GABA levels which are potentially being altered by excessive smartphone use. Since this study was observational, more research needs to be done to determine a direct link between smartphone addiction and mental health in teenagers.
