Final answer:
The worst prognosis is for children who have both ADHD and conduct disorder.
Step-by-step explanation:
According to research, the worst prognosis is for children who have both ADHD and conduct disorder. ADHD (Attention-Deficit/Hyperactivity Disorder) is a neurodevelopmental disorder characterized by difficulty maintaining attention and controlling impulses. Conduct disorder, on the other hand, is a behavioral disorder characterized by a pattern of repetitive and persistent aggressive, disruptive, and disobedient behavior.
When a child has both ADHD and conduct disorder, their symptoms and behaviors can intensify, leading to more severe difficulties in daily functioning and social interactions. It's important for these children to receive appropriate interventions and support to improve their outcomes.
