What Genes Are Behind Obsessive-Compulsive Disorder According to Australian Researchers?

Synopsis
In a groundbreaking study, Australian researchers have unveiled specific genes associated with obsessive-compulsive disorder (OCD). This discovery promises to enhance diagnosis and treatment options for individuals grappling with this debilitating condition. With a better understanding of the genetic underpinnings of OCD, new pathways for effective interventions are on the horizon.
Key Takeaways
- Identification of 30 genomic regions linked to OCD.
- Discovery of approximately 250 associated genes.
- Research conducted on over 50,000 individuals with OCD.
- Findings suggest significant overlap with other mental health disorders.
- Potential for more targeted treatments in the future.
Sydney, May 13 (NationPress) Australian scientists have pinpointed specific genes associated with obsessive-compulsive disorder (OCD), paving the way for enhanced diagnosis and treatment of this challenging mental health issue.
OCD is characterized by persistent, unwanted thoughts and fears known as obsessions.
Researchers from QIMR Berghofer, previously known as the Queensland Institute of Medical Research, discovered 30 areas in the human genome and approximately 250 genes that correlate with the disorder, as reported by Xinhua news agency.
The team conducted a comprehensive analysis of DNA from over 50,000 individuals diagnosed with OCD, alongside 2 million individuals without the condition.
“Our extensive research over the years has significantly enhanced our understanding of the genetic underpinnings of OCD,” stated Eske Derks, the lead researcher and director of the Translational Neurogenomics Laboratory at QIMR Berghofer.
The identified genes show heightened activity in the hippocampus, striatum, and cerebral cortex, brain regions that prior studies have linked to OCD, according to findings published in the journal Nature Genetics.
The research also revealed a noteworthy genetic overlap with other mental health disorders, including anxiety, depression, and eating disorders, emphasizing the intricate nature of OCD.
OCD impacts approximately 1 to 3 percent of the global population, manifesting in behaviors ranging from compulsive cleaning and checking to irrational fears and obsessive doubts regarding relationships and responsibilities.
“The disorder affects not just the individual, but also their families, as everyone tries to adapt to the presence of OCD,” commented clinical psychologist Emily O'Leary.
She further noted that individuals suffering from OCD often find themselves in a constant state of fear about making mistakes or harming loved ones.
The outcomes of this study could accelerate the process of diagnosis and lead to more targeted treatments, such as investigating the potential of existing medications used for other conditions in treating OCD, according to the researchers.
