View Original AbstractMobile and cordless phone use alters brain barrier proteins, suggesting wireless radiation compromises protective systems around your brain.
Plain English Summary
Swedish researchers examined whether long-term mobile and cordless phone use affects the blood-cerebrospinal fluid barrier by measuring transthyretin, a protein that helps protect the brain. They found that men who used phones longer had higher transthyretin levels, while women showed elevated levels when blood was drawn soon after phone calls. These changes suggest that radiofrequency radiation may alter the brain's protective barriers.
Why This Matters
This study addresses a critical gap in EMF research by examining the blood-cerebrospinal fluid barrier, which protects your brain from toxins and maintains proper brain chemistry. While most attention focuses on the blood-brain barrier, this barrier is equally important for brain health. The finding that transthyretin levels change with phone use suggests radiofrequency radiation may compromise these protective systems. The different patterns between men and women, and the immediate effects seen in women after phone calls, indicate that your brain's protective barriers respond to wireless radiation in real-time. What this means for you is that the radiation from your mobile and cordless phones may be affecting fundamental protective mechanisms in your brain, adding to the growing body of evidence that these devices produce biological effects at levels well below current safety standards.

Specific exposure levels were not quantified in this study.
Study Details
Whether low-intensity radiofrequency radiation damages the blood-brain barrier has long been debated, but little or no consideration has been given to the blood-cerebrospinal fluid barrier. In this cross-sectional study we tested whether long-term and/or short-term use of wireless telephones was associated with changes in the serum transthyretin level, indicating altered transthyretin concentration in the cerebrospinal fluid, possibly reflecting an effect of radiation.
One thousand subjects, 500 of each sex aged 18–65 years, were randomly recruited using the populatio...
The response rate was 31.4%. Logistic regression of dichotomized TTR serum levels with a cut-point o...
In this hypothesis-generating descriptive study time since first use of mobile telephones and DECT combined was significantly associated with higher TTR levels regardless of how much each telephone type had been used. Regarding short-term use, significantly higher TTR concentrations were seen in women the sooner blood was withdrawn after the most recent telephone call on that day.
