NIH-funded research University of Miami School of Medicine · NIH-11194364

This study is looking at how using cannabis affects the brains of teenagers with depression, especially in areas that deal with feelings of reward and pain, to see if it might make their depression worse over time.

What this research studies

This research investigates how cannabis, the most commonly used illicit drug among teenagers, affects brain circuits related to reward and pain in adolescents suffering from depression. It aims to understand the long-term impacts of cannabis use on these neurocircuits, particularly focusing on the habenula, a brain region involved in regulating reward and pain responses. By studying adolescents who use cannabis to self-medicate their depression, the research seeks to fill a critical gap in understanding how cannabis may worsen depression and lead to chronicity. Advanced imaging techniques will be employed to observe changes in brain function over time.

Who could benefit from this research

Good fit: Ideal candidates for this research are adolescents aged 12 to 20 who are experiencing depression and have a history of cannabis use.

Not a fit: Patients who do not use cannabis or are not experiencing depression may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to better understanding and treatment strategies for adolescents with depression who use cannabis.

How similar studies have performed: While there has been limited research specifically on cannabis use in depressed adolescents, studies on cannabis effects in other populations suggest potential for significant findings.
