ADHD stands for Attention-Deficit/Hyperactivity Disorder. It's a condition that affects how a person's brain works, making it harder for them to pay attention, sit still, or control their impulses. People with ADHD might find it challenging to focus on tasks, follow instructions, or stay organized. They might also be more active or impulsive than others.

ADHD is common in children, but it can also continue into adulthood. It's important to remember that having ADHD doesn't mean someone isn't smart or can't succeed. Many people with ADHD are very creative and have lots of energy, which can be great strengths. There are also many strategies and treatments that can help manage ADHD symptoms, such as therapy, medication, and organizational tools.
