What is ADHD?

Attention deficit and hyperactivity disorder (ADHD) is a mental health condition that affects your ability to concentrate, retain information, and maintain self-control.

ADHD is more commonly identified in children but it’s becoming more common for adults to be diagnosed with the condition. In many cases, adults are diagnosed with ADHD because the condition was left untreated during childhood. People diagnosed with ADHD often have issues with hyperactivity, behavioral self-control, and concentration.  

How is ADHD diagnosed?

Dr. Choi will carefully observe and interview you before he diagnoses ADHD and starts a treatment plan.

Children and adults present different symptoms of ADHD. Younger patients often display impulsive, inattentive, and hyperactive behaviors. Keep in mind that children with ADHD often display similar habits in many different situations, but these behaviors don’t necessarily mean that your child has ADHD. Children need to display several behaviors for a sustained period of time for an ADHD diagnosis. Some of the common behaviors include:  

  • Not paying attention or listening  
  • Trouble concentrating  
  • Easily bored or distracted  
  • Trouble staying still and quiet  
  • Incessant chatter or interrupting  

Adults are more likely to present symptoms like an inability to focus, excessive energy, disorganization, and trouble completing tasks.

Are there different classifications of ADHD?

Yes, ADHD is usually identified as one of three different classifications.

Predominantly Inattentive

If you or your child is predominantly inattentive, you have trouble paying attention or listening when someone else is speaking. You might also have trouble focusing on and completing a task or retaining new information.

Predominantly Hyperactive

If you or your child is predominantly hyperactive, you will present symptoms like fidgeting, not being able to sit still, and not being able to focus on quiet activities.


It is possible to experience a combination of the inattentive and hyperactive characteristics.

How can I tell if my child’s behavior is abnormal?

Children often display behaviors that are hyperactive and disruptive. In many cases, your child is just being a child. However, when these behaviors become extreme, prolonged and disrupt your family dynamic, you may want to seek professional assessment with Dr. Choi.

If you’re concerned about your child or think that you may have ADHD yourself, call or schedule an appointment online with Dr. Choi today.
