How teen drinking affects thinking and behavior in ADHD

ADHD and the influence of adolescent alcohol drinking on cognition and behavior

NIH-funded research Lsu Health Sciences Center · NIH-11123397

Researchers are using a genetic mouse model to learn how alcohol exposure during the teen years might worsen attention, self-control, and later drinking problems in people with ADHD.

What this research studies

This project uses mice that carry a gene change linked to ADHD (the Lphn3 knockout) to model ADHD-related brain differences. Investigators will give alcohol to adolescent mice, measure their drinking behavior, and test memory and impulse control as the animals mature. They will examine the frontal cortex — a brain region important for planning and self-control — to see whether teen drinking accelerates harmful changes. Findings will link brain changes to lasting behavior differences that could explain higher risk of alcohol problems in people with ADHD.

Who could benefit from this research

Good fit: People with ADHD who drank heavily as teenagers or are concerned about adolescent drinking increasing later alcohol problems would be most relevant to this research.

Not a fit: People without ADHD or those who never drank during adolescence are unlikely to see direct benefits from this mouse-focused project.

Why it matters

Potential benefit: If successful, the work could clarify why teens with ADHD are more vulnerable to heavy drinking and suggest ways to prevent or treat long-term problems.

How similar studies have performed: Epidemiological and animal studies have linked ADHD with higher alcohol use and shown that adolescent drinking harms frontal cortex development, but using the Lphn3 knockout specifically to study these effects is a relatively new approach.
