ADHD symptoms often manifest differently in children and adults. Children with ADHD typically exhibit hyperactivity, impulsivity, and difficulty paying attention in classroom settings. For them, behaviors like fidgeting, blurting out answers, or struggling to sit still are common signs.

In contrast, adults with ADHD may not display overt hyperactivity but might struggle with executive function, leading to issues like disorganization, forgetfulness, and difficulty managing responsibilities. Social relationships and work performance can also be impacted. Understanding these evolving symptoms is crucial for providing age-appropriate support and interventions.
