A 10 year old child is always restless, inattentive to study and always wants to play outside. Parents are extremely distressed. What is the most probable diagnosis?
**Core Concept**
The child's symptoms suggest a neurological or psychiatric disorder that affects attention, impulse control, and hyperactivity. The condition is likely to be a neurodevelopmental disorder that affects children and is characterized by symptoms of inattention, hyperactivity, and impulsivity.
**Why the Correct Answer is Right**
The most probable diagnosis is Attention Deficit Hyperactivity Disorder (ADHD). ADHD is a neurodevelopmental disorder that affects children and is characterized by symptoms of inattention, hyperactivity, and impulsivity. The child's symptoms of restlessness, inattentiveness, and desire to play outside are consistent with the diagnostic criteria for ADHD. The condition is often associated with genetic factors, brain structure abnormalities, and imbalances in neurotransmitters such as dopamine and norepinephrine.
**Why Each Wrong Option is Incorrect**
* **Option A:** While anxiety disorders can cause symptoms of restlessness and inattentiveness, they are not typically characterized by a persistent pattern of hyperactivity and impulsivity. Anxiety disorders are more often associated with fear, worry, and avoidance behaviors.
* **Option B:** Oppositional Defiant Disorder (ODD) is a disorder that affects children and is characterized by a pattern of angry, irritable, or vindictive behavior. While children with ODD may exhibit some symptoms of hyperactivity, they are not typically characterized by inattention and restlessness.
* **Option C:** Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder that affects children and is characterized by difficulties with social interaction, communication, and repetitive behaviors. While children with ASD may exhibit some symptoms of hyperactivity, they are not typically characterized by inattention and restlessness.
**Clinical Pearl / High-Yield Fact**
ADHD is a common neurodevelopmental disorder that affects approximately 8-10% of children worldwide. Early diagnosis and treatment with behavioral interventions and medications can significantly improve symptoms and outcomes.
**Correct Answer:** C.
