Reduced gray matter and altered brain connectivity are linked to problematic smartphone use
A comprehensive review of neuroimaging research suggests that problematic smartphone use is associated with distinct structural and functional alterations in the brain. These changes primarily involve neural circuits responsible for reward processing, executive control, and emotional regulation. The analysis indicates that the intense motivational pull of smartphones may stem from how these devices tap into the brain’s social cognition networks, reinforcing habits through digital social feedback and the avoidance of social exclusion. These findings were published in the journal Progress in Neuro-Psychopharmacology and Biological Psychiatry. Smartphone usage has become ubiquitous globally, integrated into almost every aspect of modern daily life for billions of people. While these devices offer numerous benefits in communication and information access, excessive engagement has been linked to negative outcomes in some individuals, including sleep disturbances, heightened anxiety, and reduced cognitive performance. Scientists have increasingly viewed this phenomenon through the lens of behavioral addiction, prompting numerous studies into the underlying neurobiology. The researchers behind the current paper aimed to synthesize the growing body of neuroimaging data to better understand the brain mechanisms …
