Potentially traumatic experiences (PTEs) refer to events where someone is exposed to situations that involve threats to life, serious injury, or danger to themselves or others. These events can include things like accidents, violence, or the death of someone close. PTEs are significant because they can have lasting effects on a person's mental health.
A research team from Norway, working with a collaborator from the U.S., used their country’s universal health care system to study how PTEs affect the mental health of children and adolescents in Hordaland County, which includes the city of Bergen. They wanted to see how experiencing PTEs influenced the likelihood of these young people seeking help from child and adolescent mental health services (CAMHS) or being diagnosed with psychiatric disorders, including ADHD.
In 2012, the study invited all 19,439 teenagers born between 1993 and 1995 in Hordaland County to participate. These teens were 16 to 19 years old at the time. Out of this group, 9,555 teens agreed to let the researchers link their personal data with the National Patient Registry (NPR), which keeps track of health records. There was no significant difference in the types or number of PTEs between those who agreed to this data sharing and those who did not.
After removing participants with incomplete information, the researchers were left with 8,755 teens. These teens’ psychiatric diagnoses, including ADHD, were taken from the NPR. The researchers asked the participants if they had ever experienced specific traumatic events, such as:
If a participant reported experiencing the death of someone close, they were asked to specify who it was (a parent, sibling, grandparent, other family member, close friend, or romantic partner). One limitation of the study was that it did not ask about bullying, which could also be a traumatic experience.
The researchers divided the teens into three trauma groups based on their experiences:
Teens in the situational and interpersonal trauma groups were more likely to see their economic situation as worse than those in the low trauma group. For example, 11% of the situational trauma group and 17% of the interpersonal trauma group considered themselves economically worse off, compared to just 6.1% of the low trauma group. Also, fewer parents of teens in the two higher trauma groups had higher levels of education, which can impact family support and resources.
After adjusting for gender and parental education, the researchers found that:
The effect was even stronger when comparing the interpersonal trauma group to the low trauma group. Teens in the interpersonal trauma group were almost five times more likely to be diagnosed with ADHD than those in the low trauma group.
One limitation of the study is that while the researchers acknowledged that sex and socioeconomic status (SES) are important factors in the relationship between trauma and psychiatric disorders, they did not directly adjust for SES. However, they did indirectly account for it by considering the education levels of the parents, which is closely related to SES.
The study showed that adolescents who experience more interpersonal trauma (like violence or sexual abuse) are at a significantly higher risk of being diagnosed with ADHD. The findings suggest that it’s important to pay special attention to teens who experience both situational and interpersonal traumas, especially those exposed to interpersonal violence. Early intervention and support could be key to helping these adolescents manage their mental health.

A recent study from Istanbul sheds light on how psychiatric admissions and diagnoses changed during the first few months of the pandemic compared to previous periods, offering critical insights for parents, clinicians, and policymakers.
This study, conducted by a team of researchers led by Ozalp Ekinci, examined psychiatric admissions among children and adolescents during 2019 and 2020.
By looking at diagnosis rates for various psychiatric conditions, the researchers aimed to pinpoint shifts in the mental health landscape as a direct response to the pandemic.
The analysis revealed several notable trends in psychiatric diagnoses among children and adolescents:
This study’s findings highlight some key takeaways that can guide mental health support efforts for children and adolescents:
As we continue to see the effects of the COVID-19 pandemic on mental health, studies like this one serve as important reminders of the unique mental health needs of young people. Supporting children and adolescents through proactive and targeted mental health services—especially during times of crisis—will be crucial to fostering resilience and well-being in future generations.
Adult ADHD has long been a subject of debate in the field of mental health, with previous estimates of its prevalence varying widely. To achieve a more precise understanding, an international team of researchers conducted a new umbrella review and meta-analysis, offering an updated estimate of adult ADHD rates worldwide.
This large-scale analysis combined five systematic reviews and meta-analyses, incorporating data from 57 unique primary studies. Altogether, the research synthesized findings from a pooled total of over 21 million participants. This comprehensive approach provided a more accurate estimate of the global prevalence of ADHD in adults.
The study concluded that the worldwide prevalence of adult ADHD is 3.1%, with a 95% confidence interval ranging from 2.6% to 3.6%. This estimate falls within the range of earlier reports but provides a more targeted understanding of the rate at which ADHD affects adults globally.
The researchers described this prevalence rate as “relatively high.” They noted that it is only slightly lower than the estimated prevalence of major mental health conditions like schizophrenia (4%) and major depressive disorder (5%)—disorders that have historically received significant attention and resources worldwide.
Moreover, the prevalence of adult ADHD is higher than that of several other well-known mental health conditions, including bipolar disorder (1%), as well as anxiety disorders such as PTSD (Post-Traumatic Stress Disorder), OCD (Obsessive-Compulsive Disorder), GAD (Generalized Anxiety Disorder), and panic disorders.
This updated estimate emphasizes that ADHD is a significant global mental health concern in adults, comparable to or exceeding the prevalence of other disorders that are often more widely recognized. These findings underscore the need for greater awareness, research, and treatment options for adult ADHD, which is still frequently misunderstood or overlooked in the broader discourse of mental health.
By providing a clearer picture of how prevalent ADHD is in adult populations around the world, this study contributes valuable data that could shape future research, policy, and clinical approaches.
Attention-Deficit/Hyperactivity Disorder (ADHD) remains a prevalent condition among children and adolescents in the United States. A recent analysis based on the National Health Interview Survey (NHIS), conducted by the National Center for Health Statistics at the CDC, provides an updated look at ADHD prevalence from 2018 to 2021. Here’s a closer look at what the data reveals.
The NHIS is an annual survey primarily conducted through face-to-face interviews in respondents’ homes. Telephone interviews are used as a substitute in cases where travel is impractical. For each family interviewed, one child aged 3-17 is randomly selected for the survey through a computer program. Over the four years studied (2018-2021), a total of 26,422 households with children or adolescents participated.
The analysis found that 9.5% of children and adolescents in the United States had been diagnosed with ADHD, based on reports from family members. However, the prevalence varied significantly with age:
The increase in ADHD diagnosis with age underscores the importance of monitoring children’s developmental needs as they progress through school and adolescence.
The survey revealed a notable difference in ADHD prevalence between genders, with 12.4% of males diagnosed compared to 6.6% of females—nearly a two-to-one gap. This aligns with previous research indicating that ADHD is more frequently diagnosed in boys than girls, though awareness of how ADHD presents differently across genders is growing.
Family income played a significant role in ADHD prevalence, particularly among lower-income groups:
This pattern suggests that socioeconomic factors might influence the diagnosis and management of ADHD, with lower-income families possibly experiencing greater barriers to early diagnosis or consistent treatment.
Geographic location also impacted ADHD rates. Prevalence was highest in the South (11.3%), followed by the Midwest (10%), the Northeast (9.1%), and significantly lower in the West (6.9%). These variations could reflect regional differences in healthcare access, diagnostic practices, or cultural attitudes towards ADHD.
Despite these variations in demographics, the overall prevalence of ADHD remained relatively stable across the study period from 2018 to 2021, showing no significant changes by year.
The findings from this updated analysis provide a clearer picture of ADHD’s prevalence across different demographic groups in the United States. They highlight the need for tailored approaches to diagnosis and care, taking into account factors like age, gender, income, and geographic location. With ADHD being a common condition affecting nearly 1 in 10 children, ongoing research and support for families are crucial to ensure that those with ADHD receive the care and resources they need.
This study reinforces the importance of awareness and early intervention, especially for families in underserved regions or those facing economic challenges. As clinicians and educators continue to support children with ADHD, understanding these demographic trends can help in creating more equitable access to diagnosis and treatment.
