Can two weeks without your phone change your brain?
NCT ID NCT07663474
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing what happens to dopamine transporters in the brain when people stop using their mobile phones for two weeks. Thirty healthy adults who own iPhones will have their phone use restricted, then undergo a PET scan to measure dopamine transporter levels. After that, they will use their phones freely for another two weeks and have a second PET scan. The goal is to see if limiting phone use changes brain chemistry related to addiction.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Mobile phone restriction
What this could lead to
If it works, this could help us understand how smartphone use affects brain chemistry, potentially informing future addiction treatments.
What could go wrong
This is a small, early-stage observational study with only 30 participants. It measures a brain marker (dopamine transporter binding) rather than clinical outcomes, so real-world implications are uncertain.
