Concept:Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental condition whose core symptoms are an ongoing pattern of inattention, hyperactivity, and impulsivity that interferes with daily functioning.
Explanation:ADHD is primarily defined by persistent impulsivity, hyperactivity, and an inability to sustain attention. Impulsivity means acting without thinking—interrupting others, making hasty decisions, or having difficulty waiting for one’s turn. These symptoms appear before age 12 and affect multiple settings (school, home, etc.).
Among the given options:
- Option A (high depression and mood swings) is not a defining feature of ADHD; emotional dysregulation can occur but is not the hallmark.
- Option C (restricted and repetitive behaviors) is typical of Autism Spectrum Disorder (ASD), not ADHD.
- Option D (delayed motor and language skills) is associated with other developmental disorders, not ADHD.
Only Option B correctly captures the core diagnostic characteristic of ADHD: an ongoing pattern of impulsivity.
Answer:Ongoing pattern of impulsivity (Option B).
