What is ADHD?

Attention deficit hyperactivity disorder (ADHD) is a condition in which people have a hard time paying attention. Adults with ADHD also may be more active than normal. They tend to act without thinking. ADHD may make it harder for them to focus, get organized, and finish tasks.

ADHD most often starts in childhood and lasts into adulthood. Many adults don't know that they have ADHD until their children are diagnosed. Then they begin to see their own symptoms.

Doctors don't know what causes ADHD. But it tends to run in families.

What are the symptoms?

The most common types of ADHD symptoms in adults are attention problems and hyperactivity.

Attention problems

Adults with ADHD often find it hard to:

• Finish tasks that don't interest them or aren't easy. But they may become obsessed with activities that they find interesting and enjoy.
• Focus their attention on conversations, reading materials, or jobs. They may change jobs a lot.
• Remember things. They may misplace or lose things.
• Pay attention. They are easily distracted. They find it hard to focus on one task.
• Organize tasks and activities. They may not be able to manage their time well. And they may have a hard time keeping their things in order.

Hyperactivity

Adults with ADHD may:

• Fidget. They may swing their legs, shift in their seats, or tap their fingers.
• Move around a lot. They may feel "revved up" or on the go. They may not be able to slow down until they are very tired.
• Find it hard to relax. They may feel restless and find it hard to do quiet things like read or watch TV.
• Talk a lot or interrupt others. They may blurt out an answer before a question has been completed.
• Find it hard to wait their turn, such as when they're in line.

How does ADHD affect daily life?

ADHD in adults may affect:

• Job performance. They may find it hard to organize their work, manage their time, and focus on one task at a time. They may forget, misplace, or lose things. They may quit their jobs out of boredom.
• Relationships. Adults with ADHD may find it hard to focus their attention on conversations. It is hard for them to "read" the behaviour and moods of others and express their own feelings.
• Temper. They may get easily frustrated. This often can make it harder for them to deal with stress. These adults may overreact and have a short, quick temper.
• The ability to solve problems. Adults who have a hard time waiting for things they want may act before they think about the effect of their actions. They may take part in risky behaviours. These include unprotected sex, unsafe driving, alcohol and drug use, or unwise business ventures.
