Heavy mobile phone users showed significantly worse attention and concentration despite normal brain scans, suggesting cognitive impairment without visible damage.

Plain English Summary

Summary written for general audiences

Researchers compared brain scans and cognitive tests between female medical students who used mobile phones less than 30 minutes daily versus those using them more than 90 minutes daily. While brain structure appeared unchanged, the heavy phone users performed significantly worse on attention and concentration tests. This suggests that regular mobile phone use may impair cognitive function even in young, healthy adults.

Why This Matters

This study adds important evidence to growing concerns about mobile phone impacts on brain function. What makes these findings particularly compelling is that they occurred in young, healthy medical students after relatively modest exposure differences. The reality is that many people today exceed 90 minutes of daily phone use by substantial margins. The researchers found measurable attention deficits without any detectable structural brain changes, suggesting functional impairment may precede visible damage. While the study was limited to young women and didn't measure specific radiation levels, it aligns with broader research showing cognitive effects from radiofrequency exposure. The science demonstrates that our brains respond to mobile phone radiation in ways that can affect daily performance, even when we can't see physical changes on brain scans.

Exposure Information

Specific exposure levels were not quantified in this study. The study examined exposure from: mobile phones Duration: Low (<30 min/day) vs high (>90min/day)

Study Details

The aim of the present study was to evaluate the effects of mobile phones on the morphology of the human brain and on cognitive performance using stereological and spectroscopic methods and neurocognitive tests.

Sixty healthy female medical school students aged 18–25 years were divided into a low exposure group...

Analysis of the spectroscopic results revealed no significant difference in specific metabolites bet...

Based on these results, we conclude that a lack of attention and concentration may occur in subjects who talk on mobile phones for longer times, compared to those who use phones relatively less.
