Which of the following childhood disorder improves with increase in age _________
**Core Concept**
Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder characterized by symptoms of inattention, hyperactivity, and impulsivity in children. The disorder is often associated with difficulties in executive function, social skills, and emotional regulation.
**Why the Correct Answer is Right**
ADHD symptoms tend to improve with age as the brain continues to mature. Research suggests that the prevalence of ADHD decreases significantly during adolescence and early adulthood, with some studies indicating that up to 70% of children with ADHD may outgrow their symptoms by young adulthood. This improvement is thought to be related to the ongoing development of the prefrontal cortex, which is responsible for executive function and impulse control.
**Why Each Wrong Option is Incorrect**
* **Option A:** This is incorrect because Oppositional Defiant Disorder (ODD) is characterized by a pattern of negative, hostile, and defiant behavior, which does not necessarily improve with age.
* **Option B:** This is incorrect because Conduct Disorder (CD) is a more severe condition that involves a pattern of behavior that violates the rights of others or major age-appropriate societal norms, and its symptoms do not improve with age.
* **Option C:** This is incorrect because Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder that affects communication, social interaction, and behavior, and its symptoms do not necessarily improve with age.
**Clinical Pearl / High-Yield Fact**
ADHD is often associated with other neurodevelopmental disorders, such as learning disabilities and Tourette's syndrome, and early diagnosis and treatment are crucial for improving outcomes.
**Correct Answer: D. ADHD**
