GABAmech Trial Summary
This trial is testing if lorazepam affects blood oxygenation level dependent (BOLD) signal by fMRI after viewing affective stimuli in people with mental illness.
Who is the study for?
This trial is for individuals aged 16-35 with psychotic illnesses like schizophrenia or bipolar disorder, and healthy subjects to serve as a comparison. Participants must not have had substance use disorders recently, be willing to consent, able to handle small spaces without anxiety, and not on certain medications or involuntary treatment orders.Check my eligibility
What is being tested?
The study tests how lorazepam affects brain function in people with psychosis by using fMRI scans while they view emotional stimuli. It compares the effects of lorazepam against a placebo over several sessions involving interviews, questionnaires, blood tests, and MRIs.See study design
What are the potential side effects?
Lorazepam may cause drowsiness, dizziness, tiredness, blurred vision, unsteadiness. During an MRI scan some might feel discomfort due to the enclosed space or loud noises from the machine.
