What this Trial Is About
Researchers are investigating how restricting mobile phone use affects dopamine transporter levels in healthy adults aged 19 to 40. The study focuses on daily mobile phone users who own an iPhone, aiming to understand the impact of mobile phone use on dopamine binding in the brain. Participants undergo two different 2-week periods one with free mobile phone use and another with mobile phone use restricted. After each period, they will have PET scans to measure dopamine transporter levels. The study monitors changes in brain dopamine transporter binding related to mobile phone usage patterns. During the study, participants will be monitored over 4 weeks, including periods of normal and restricted phone use. Assessments include PET scans after each 2-week phase to measure dopamine transporter changes. The trial includes healthy adults and tracks mobile phone usage using the Screentime application to ensure adherence and accurate data collection.
