NA · University of Texas at Austin · NCT05838274

This study looks at how alcohol affects young adults with bipolar disorder compared to their peers to see if it leads to problems with drinking over time.

What this trial studies

This study investigates the subjective and neural responses to alcohol in young adults with bipolar disorder compared to their typically developing peers. It involves a placebo-controlled alcohol administration and MRI assessments to explore how these responses change over time and their relationship with alcohol use and symptoms. The study aims to identify biological risk factors that may predict the development of alcohol use disorders in individuals with bipolar disorder, utilizing a longitudinal approach over two years. Participants will undergo clinical assessments and MRI scans at baseline and follow-ups to track changes in sensitivity to alcohol and associated neural changes.

Who should consider this trial

Good fit: Ideal candidates are young adults aged 21-26 who have experienced at least moderate alcohol consumption and are currently euthymic with a diagnosis of bipolar disorder.

Not a fit: Patients with significant medical illnesses, severe alcohol use disorders, or contraindications to MRI may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved interventions and prevention strategies for alcohol use disorders in individuals with bipolar disorder.

How similar studies have performed: While there have been studies on alcohol use disorders, this specific longitudinal approach in the context of bipolar disorder is relatively novel.
