What this research studies

Many people struggle with hair pulling and skin picking, which are difficult to treat and currently lack effective medications. This project looks into the genetic factors that contribute to these behaviors, hoping to uncover the underlying biological pathways. By studying DNA from families affected by these conditions, and using advanced lab models of brain development, we hope to identify specific genes involved. This deeper understanding is a crucial step toward developing new and more effective treatments for those affected.

Who could benefit from this research

Good fit: Ideal candidates for this type of research would be individuals with trichotillomania or excoriation disorder, particularly those who can participate with their parents as a family trio.

Not a fit: Patients who do not have trichotillomania or excoriation disorder, or those not interested in genetic research, would not directly benefit from this specific study.

Why it matters

Potential benefit: If successful, this research could lead to the discovery of new genetic targets for medications, offering hope for more effective treatments for hair pulling and skin picking.

How similar studies have performed: While previous work suggests a genetic link for these behaviors, identifying specific risk genes has been challenging, making this approach a critical next step with promising preliminary data.
