This study found no blood-brain barrier disruption from wireless phone use, but low response rates and small effect sizes limit definitive conclusions.

Plain English Summary

Summary written for general audiences

Swedish researchers tested whether wireless phone use affects the blood-brain barrier (the protective boundary between blood and brain tissue) by measuring S100B protein levels in blood samples from 1,000 adults. They found no significant association between phone use and elevated S100B levels, suggesting that wireless phones don't appear to compromise blood-brain barrier integrity based on this biomarker.

Study Details

Using serum S100B as a putative marker of BBB dysfunction we performed a descriptive cross-sectional study to investigate whether protein levels were higher among frequent than non-frequent users of mobile and cordless desktop phones.

One thousand subjects, 500 of each sex aged 18-65 years, were randomly recruited using the populatio...

The response rate was 31.4%. The results from logistic and linear regression analyses were statistic...

This study failed to show that long- or short-term use of wireless telephones was associated with elevated levels of serum S100B as a marker of BBB integrity. The finding regarding latency of UMTS use may be interesting but it is based on small numbers. Generally, S100B levels were low and to determine whether this association - if causal - is clinically relevant, larger studies with sufficient follow-up are needed.
