Recent findings from the University of Edinburgh have shed light on the troubling correlation between Attention Deficit Hyperactivity Disorder (ADHD) and increased rates of anxiety and depression among teenagers. Published in the Journal of Attention Disorders, this pioneering study explores how ADHD symptoms may contribute to emotional distress, notably through factors such as self-esteem and parental mental health.
ADHD and Mental Health: A Concerning Connection
The research, which involved over 5,000 adolescents aged 11, 14, and 17, identifies a statistically significant relationship between ADHD and additional emotional challenges, including low self-esteem and the mental health status of parents. Aja Murray, the lead researcher and a professor of developmental psychology at the university, emphasised the importance of recognising that “internalising problems like anxiety and depression are elevated for young people with ADHD symptoms.”
Murray noted that understanding the multifaceted nature of this relationship could help prioritise interventions that have the greatest impact on the lives of affected youths. She stated, “There’s lots of things that might contribute to that link between ADHD symptoms and anxiety and depression. It’s quite good to understand what are some of the biggest things that we should be focusing on to have the most impact.”
The Role of Self-Esteem and Parental Influence
The study identified a “small but statistically significant link” between low self-esteem and parental mental health issues, which correlates with an increased risk of mental health problems for adolescents with ADHD. This trend was particularly evident among girls, especially those facing difficulties in social interactions. The findings suggest that various factors work collectively, albeit with a modest effect, to connect ADHD symptoms with additional emotional issues during adolescence.

Cara Katz, a child and adolescent psychiatrist, acknowledged the critical developmental stage of adolescence, where identity formation plays a pivotal role. She stated, “When kids or people have ADHD, sometimes they get more negative feedback from their environment… they take in how their environment perceives them and internalise that.” This negative feedback loop can exacerbate feelings of inadequacy and further entrench mental health struggles.
Tailoring Support for Young People with ADHD
The implications of this research are profound, as it highlights the need for targeted support systems tailored to the specific needs of adolescents with ADHD. Amori Mikami, a psychology professor at the University of British Columbia, reiterated the emotional toll that negative perceptions can have on these young individuals. “Kids who have ADHD symptoms… often think that they’re bad kids because they’re getting in trouble a lot at school, at home,” she explained. The cumulative effect of criticism from various sources can lead to significant mental health challenges.
Furthermore, the study suggests that ADHD symptoms tend to become more pronounced as teenagers approach adulthood, particularly by the age of 17. Jeremy Williams, CEO of ADHD Counselling Canada, remarked on the complexities of adolescence, explaining that the highly stimulating digital environments today can amplify ADHD symptoms. The increased visibility of these symptoms may also be attributed to a growing willingness among young people to report their struggles.
Gender Differences in ADHD and Mental Health
Murray’s research also uncovered notable differences in how ADHD affects boys and girls. Girls with higher ADHD symptoms reported more profound difficulties with peer relationships, which in turn led to increased anxiety and depression. This gender disparity highlights the necessity of tailoring support for boys and girls differently, with a particular focus on fostering healthy friendships for girls and addressing risk-taking behaviours in boys.

Murray’s observations suggest that societal expectations play a significant role in how ADHD symptoms manifest and are perceived. While boys may be more likely to exhibit outward behavioural problems, girls often internalise their struggles, leading to anxiety and depression.
Why it Matters
Understanding the connections between ADHD and mental health is crucial for developing effective support systems for young people. As the study indicates, addressing the emotional well-being of adolescents with ADHD requires a comprehensive approach that involves the family unit and considers gender-specific needs. By fostering an environment that promotes positive self-esteem and better mental health among parents, society can significantly improve the quality of life for these young individuals, ultimately leading to more resilient and healthier futures.
