About this study

This study explores the impact of long-term benzodiazepine (BZDs) use on cognitive function and associated neuroimaging markers. While BZDs are established treatments for conditions like anxiety and insomnia, recent warnings highlight risks, including neurocognitive effects. Neuroimaging studies indicate potential neuroprotective effects of BZDs. Functional near-infrared spectroscopy (fNIRS) measures cerebral cortex function during cognitive tasks. Combining fNIRS with mood and cognitive scales, this study assesses cortical activation. 2-deoxy-2-fluoro-D-glucose-positron emission tomography (FDG-PET) evaluates brain metabolism. DPA-714 PET assesses neuroinflammation. The primary objective is to compare brain functional activation, metabolism, and neuroinflammatory levels between long-term BZD users and non-users. This comprehensive approach aims to provide insights into BZD effects on cognition and associated brain markers.
