How hormones affect alcohol use and fear responses

Endocrine regulation of alcohol consumption and fear learning

NIH-funded research Iowa City VA Medical Center · NIH-10975914

This study is looking at how alcohol use disorder and post-traumatic stress disorder affect each other in veterans, and it wants to see how a hormone called FGF21 might play a role in drinking habits and dealing with fear, all to find better ways to help those who are struggling with both conditions.

What this research studies

This research investigates the relationship between alcohol use disorder (AUD) and post-traumatic stress disorder (PTSD), particularly in veterans. It aims to understand how the hormone fibroblast growth factor 21 (FGF21) influences alcohol consumption and fear learning. By exploring the neural pathways involved, the research seeks to uncover new treatment strategies for individuals suffering from both AUD and PTSD. Patients may be involved in studies that assess their hormonal levels and alcohol consumption behaviors.

Who could benefit from this research

Good fit: Ideal candidates for this research are adults, particularly veterans, who are diagnosed with both alcohol use disorder and post-traumatic stress disorder.

Not a fit: Patients who do not have alcohol use disorder or post-traumatic stress disorder may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to new therapies that effectively treat individuals with co-occurring AUD and PTSD.

How similar studies have performed: While the relationship between AUD and PTSD has been studied, the specific hormonal mechanisms being investigated in this research are novel and have not been extensively tested.
