Executive function is controlled by the front of the brain and allows people to do things such as problem solve, organise, make decisions and plan. Without realising it we use them to do everyday tasks like driving, cooking and chores. Executive dysfunction or cognitive function difficulties means that someone can find it difficult to do some or all of these things, which can make life very difficult.   It may change the way people store and process information, affecting memory, the way they read or being able to tell the time. It may also affect people’s self-control, concentration or motivation, or how comfortable people feel in large groups and their social behaviour.

People may often experience cognitive difficulties following a stroke or brain injury. This could include how they move or what they are able to do, such as driving, operating machinery or sitting for long periods.

Many people with ADHD also have executive dysfunction.
