Attention deficit hyperactivity disorder (ADHD) is a group of behavioral symptoms that include inattentiveness, hyperactivity and impulsiveness.

The exact cause of ADHD is unknown, but the condition has been shown to run in families. Research has also identified a number of possible differences in the brains of people with ADHD compared to those who don't have the condition.
Other factors that have been suggested as potentially having a role in ADHD include:
• developmental problem
• smoking, alcohol or drug abuse during pregnancy

ADHD can occur in people of any intellectual ability, although it's more common in people with learning difficulties.

Symptoms of ADHD tend to be noticed at an early age and may become more noticeable when a child's circumstances change, such as when they start school. Most cases are diagnosed when children are 6 to 12 years old.
The symptoms of ADHD usually improve with age, but many adults who are diagnosed with the condition at a young age continue to experience problems.
People with ADHD may also have additional problems, such as sleep and anxiety disorders.

Although there's no cure for ADHD, it can be managed with appropriate educational support, advice and support for parents and affected children, alongside medication, if necessary.
Medication is often the first treatment offered to adults with ADHD, although psychological therapies such as cognitive behavioral therapy (CBT) may also help.
 

Looking after a child with ADHD can be challenging, but it's important to remember that they can't help their behavior.
Some issues that may arise in day-to-day life include:
• getting your child to sleep at night
• getting ready for school on time
• listening to and carrying out instructions
• being organized
• social occasions
• shopping
