Yes, children with ADHD are at a higher risk of developing ADHD and conduct disorder. The impulsivity, hyperactivity, and difficulty with emotional regulation associated with ADHD can contribute to the development of more serious behavioural issues, such as aggression, defiance, and other disruptive behaviours that characterise conduct disorders. 

Children with ADHD often struggle with behavioural risks like poor impulse control, which can lead to acting out in ways that go beyond typical ADHD symptoms. When these behaviours are not addressed, they can escalate into more serious issues, making it more difficult to manage relationships and succeed in school. The overlap between ADHD and conduct disorder can complicate diagnosis and treatment, as both conditions share some common traits, such as aggression and difficulty following rules.

Common Symptoms 

Impulsivity and aggression 

ADHD and conduct disorder often go hand in hand, with children acting impulsively and displaying aggressive behaviours, such as hitting or yelling. 

Disregard for rules 

Children with both conditions may struggle to follow rules at school or home, often exhibiting defiant behaviour. 

Social difficulties 

These children may also struggle with forming positive relationships, as their behaviour may lead to conflict with peers and adults. 

Early identification of ADHD and conduct disorder is crucial for addressing the diagnosis risks and implementing appropriate interventions, which can help reduce the severity of symptoms and support healthier behaviour patterns.
