ADHD symptoms are divided into three key areas: inattention, impulsivity and hyperactivity. 1. Inattention - When people experience inattention, it can be hard for them to focus on things for a long period of time. They might forget important things like tasks they really need to do, or have trouble following instructions at school, work or home. This can lead to unfinished tasks or switching between tasks without finishing them. It can be tough to concentrate on things that need a lot of mental effort over a long period of time. 2. Impulsivity - Impulsivity is when you have a difficult time stopping yourself from doing something you feel like doing, even if you know it’s not a good idea. Some people call this difficulty controlling impulses. This can make it tough to wait for things or to think before acting. For example, feeling frustrated about waiting a turn in conversation and interrupting others. 3. Hyperactivity - Hyperactivity is when someone feels restless and fidgety. It can be difficult to sit still, and the person may have a strong urge to talk and move around a lot. Some people describe it like they have a motor inside that won't stop or slow down, and they keep going even when they're tired. This can make it hard to participate in activities, or games calmly. Despite its challenges, lots of people with ADHD embrace their unique strengths and perspectives, and find ways to thrive in their personal, student or professional lives.
