According to the text snippets, ADHD (Attention-deficit hyperactivity disorder) is a condition that can affect students in various ways, including difficulty focusing, paying attention, listening, and putting effort into schoolwork. It can also lead to fidgetiness and restlessness. These symptoms can interfere with social, academic, and occupational functioning, potentially resulting in rejection and low self-esteem. Moreover, children with ADHD may struggle with tasks such as writing, reading, and staying organized. The condition may also affect their ability to control their desire to move, making it challenging for them to participate in the classroom and learn effectively. Teachers play a crucial role in recognizing and supporting students with ADHD.
