Attention Deficit Hyperactivity Disorder, commonly known as ADHD, is a neurodevelopmental disorder that primarily affects children but can continue into adulthood. The symptoms of ADHD are generally categorized into two main types: inattentiveness and hyperactivity-impulsivity. Inattentiveness symptoms include difficulty sustaining attention in tasks or play activities, frequent careless mistakes in schoolwork or other activities, often seeming not to listen when spoken to directly, difficulty following through on instructions and completing tasks, trouble organizing tasks and activities, avoidance or reluctance to engage in tasks that require sustained mental effort, losing items necessary for tasks and activities, being easily distracted by extraneous stimuli, and forgetfulness in daily activities.Hyperactivity-impulsivity symptoms involve fidgeting with or tapping hands or feet, leaving seat in situations when remaining seated is expected, running or climbing in inappropriate situations, inability to play or engage in activities quietly, being often "on the go" or acting as if "driven by a motor," talking excessively, blurting out answers before questions have been completed, difficulty waiting for one's turn, and interrupting or intruding on others' conversations or games.It is important to note that not all individuals with ADHD will exhibit all these symptoms, and the severity can vary widely. Proper diagnosis and treatment by a healthcare professional are essential for managing ADHD effectively.
