ADHD is thought to affect as many as one in 20 people in the UK - but getting a diagnosis can be difficult, particularly when it lasts into adulthood.
ADHD stands for Attention Deficit Hyperactivity Disorder, and is a condition that affects someone's behaviour; the exact cause is unknown, but symptoms are often noticed at an early age and most cases are diagnosed in children under 12 years old. However, diagnosing the condition in adults is more difficult, as there is some disagreement about whether the list of symptoms used to diagnose children and teenagers also applies to adults, according to the NHS.
Adults who have ADHD may find that they experience symptoms which negatively affect them in daily life, such as forgetfulness, restlessness, poor organisational skills, lack of attention to detail or an inability to focus. The NHS says that the signs of ADHD can be more difficult to define beyond childhood, but answering some simple questions on how you feel in your daily life may help you find out whether you might have the condition.
