Children with ADHD often exhibit symptoms such as difficulty paying attention, making careless mistakes, and being easily distracted. They may also display signs of hyperactivity, such as constant fidgeting, an inability to stay seated, and excessive talking. Impulsivity is another common trait, where children might act without thinking, interrupt others frequently, or have trouble waiting their turn. These symptoms can affect a child's performance in school and their interactions with peers, making early identification and intervention essential.
