Attention issues in children are common, often affecting their focus in school and other activities. But new research from the University of California-Los Angeles (UCLA) is shining a light on a possible long-term impact: a heightened risk for psychiatric conditions like psychosis or schizophrenia in adolescence or adulthood.
While most children with attention difficulties won’t go on to develop serious psychiatric conditions, a combination of poor childhood attention spans and specific genetic markers may increase the risk. This groundbreaking study, published in Nature Mental Health, explores how early attention issues and genetics intersect to influence a child’s mental health trajectory.
A Closer Look at Childhood Attention Issues
Attention-related difficulties in children can manifest as restlessness, difficulty in focusing, and challenges with organization. Such issues are usually manageable, but when compounded by certain genetic factors, they may represent a risk marker for more severe mental health issues later in life.
According to lead researcher Dr. Carrie Bearden, a professor at UCLA Health Semel Institute and the UCLA Brain Research Institute, understanding the role of these early attention problems and how they relate to future psychosis could transform mental health interventions. By identifying risk factors early on, specialists hope to develop targeted strategies to mitigate potential future psychiatric concerns.
What is Psychosis? Understanding the Basics
The National Institute of Mental Health (NIMH) defines psychosis as a mental state where there’s a partial loss of contact with reality. During an episode, a person may experience disordered thoughts, hallucinations, or delusions, making it difficult to differentiate what’s real from what’s not. Psychosis often begins in adolescence or young adulthood, and its onset is typically influenced by both genetic and environmental factors.
Key Characteristics of Psychosis:
- Hallucinations: Seeing or hearing things that aren’t there.
- Delusions: Strong beliefs that aren’t rooted in reality.
- Disorganized Thinking: Difficulty organizing thoughts and speech.
Conditions such as schizophrenia, bipolar disorder, and severe depression are sometimes accompanied by episodes of psychosis. The UCLA study now suggests that early attention issues in children could be one of several factors that set the stage for such experiences later on.
The UCLA Study: Investigating the Attention-Psychosis Link
Dr. Bearden’s research team at UCLA analyzed the cognitive, brain, and genetic data of over 10,000 children, tracking them from around age 9 and into adolescence. This extensive study sought to find connections between childhood attention problems, certain genetic markers, and the likelihood of psychotic symptoms emerging during teenage years.
The research found that attention-span issues in childhood accounted for roughly 4% to 16% of the link between genetics and the risk of developing psychotic symptoms in the teenage years. This percentage might seem low but signals that while attention problems contribute to the risk, they aren’t the sole cause.
Study Highlights:
- Childhood attention issues contribute to the risk of psychosis but are not definitive predictors.
- Genetics play a significant role, especially when combined with cognitive and environmental factors.
- New polygenic scores (a combined measure of multiple genes) may help identify at-risk individuals more accurately in the future.
UCLA researchers also underscore that having genetic markers for attention issues and psychosis risk does not guarantee the onset of a psychiatric disorder. Environmental factors, resilience, and interventions can influence whether these risks develop into full-blown conditions.
Decoding Polygenic Scores and Psychosis Risk
A major goal for researchers like Dr. Bearden and her team is to refine a genetic “polygenic score” that could help predict the likelihood of psychosis development. A polygenic score reflects the cumulative effect of multiple genes associated with a particular trait or disorder. Currently, scientists use such scores to assess risks for diseases like cancer and heart disease. In mental health, similar scores could provide insights into which individuals are most at risk for psychotic disorders.
Potential Benefits of Polygenic Scoring in Mental Health:
- Early Intervention: Identify children who might benefit from early therapeutic interventions.
- Personalized Treatment: Tailor preventive measures to those with a higher genetic predisposition.
- Informed Guidance: Offer better support to families and educational institutions based on individual risk profiles.
While the accuracy of polygenic scoring in predicting psychosis is still evolving, researchers are optimistic that the next few years will see significant advances.
Exploring Other Contributing Factors for Psychosis
Attention issues and genetics are only part of the equation. Environmental factors such as childhood trauma, stressful family dynamics, and substance abuse can increase the risk of psychosis or schizophrenia, particularly during critical developmental phases.
Psychiatric researchers believe that mental health conditions like schizophrenia often result from a complex interplay of genetics, cognitive traits, and life experiences. This multilayered nature of psychosis underscores why it’s essential not to draw single-factor conclusions from studies on childhood attention and genetic predisposition alone.
Addressing Childhood Attention Issues Early: Potential Interventions
Experts emphasize that early intervention can make a difference for children exhibiting attention-related issues, regardless of their genetic predisposition. While some children may naturally grow out of attention challenges, others may need structured support.
Effective Early Interventions for Attention Issues:
- Behavioral Therapy: Helps children develop focus and self-control.
- Parental Training: Educates parents on positive reinforcement strategies.
- School-Based Support: Ensures children receive the necessary academic accommodations.
- Mindfulness Techniques: Practices like meditation and deep breathing can improve focus.
Addressing these issues early may prevent attention problems from worsening and potentially reduce the risk of later mental health complications. While attention issues alone don’t predict psychosis, taking proactive steps in childhood can strengthen resilience and improve overall well-being.
Why This Research Matters: A New Path for Mental Health Prevention
Dr. Bearden and her UCLA team hope that findings like these will shift the focus in psychiatry from treatment to prevention. By identifying and addressing factors in childhood that contribute to mental health risks, it may be possible to reduce the incidence of severe mental health conditions like schizophrenia and psychosis.
Additionally, advancements in genetic research could open the door for targeted therapies that reduce psychosis risk even before symptoms emerge. For now, the study’s findings encourage further research into both the genetic and behavioral aspects of psychosis risk.
Ongoing Research Efforts:
- Genetic Profiling: As polygenic scores become more refined, they could become valuable tools for predicting psychosis.
- Cognitive Training: Programs that help children enhance their attention and cognitive skills may mitigate some risk factors.
- Environmental Support: Reducing childhood exposure to stress, trauma, and abuse could also lower psychosis risk.
By leveraging these insights, future mental health professionals may have a broader toolkit for early intervention, ultimately helping reduce the burden of psychotic disorders on families and communities.
