Impulsivity, hyperactivity and inattentiveness are common with ADHD.
- Impulsiveness causes the person to react before thinking of what the outcome might be for example crossing a busy road without checking how safe this is.
- Hyperactivity means that the individual may find sitting still very difficult and may feel the need to jump, run around or move constantly.
- Inattentiveness means that the person may have difficulty focusing on something for a long time, or staying focused for long enough to complete as task.
