Attention Deficit Hyperactivity Disorder, ADHD or ADD, is often thought of as a condition experienced by children. But it is a lifelong condition that can be diagnosed in adults, too.

In fact, trends show a rise in adult diagnoses in the last decade. The Center for Disease Control reports that nearly 15.5 million adults in the U.S. are currently experiencing ADHD. 

What Is ADHD?

ADHD is a neurological disorder. People with the condition have trouble managing their attention and can have trouble with hyperactive or impulsive behavior. These symptoms can interfere with work, routine tasks, home life and relationships — especially if the condition is left untreated.

Adults with ADHD may:

• Have trouble completing lengthy tasks, unless they’re interesting.
• Struggle to stay organized and remember details.
• Have a hard time tolerating frustration or regulating their emotions.
• Find it challenging to control their behavior.
• Have trouble sitting still for long periods.
• Feel restless and fidgety.

People experiencing ADHD may also find it harder to stay on top of health activities like exercise and minding their eating habits. Sleep issues are also common among adults with ADHD.

They are also often at higher risk for drug or alcohol use issues. These substances can become a way of self-medicating to cope with symptoms. Studies show that 60 to 70 percent of adults with ADHD may experience other mental health conditions, such as mood, anxiety and substance use disorders.

How ADHD Diagnosis Can be Missed

You may wonder why some people are not diagnosed sooner, before adulthood. There are various reasons that can lead to a missed diagnosis. 

Teachers and parents may not notice symptoms. A child’s lack of attention may not raise concern, especially if their behavior isn’t disruptive or over active.

Another possibility is that the person may have found other ways to cope with or mask their struggles as a child or teenager. A person’s symptoms can be milder when they have less stress. Their condition may become more challenging as they face the responsibilities and stresses of adulthood.

Diagnosis and Treatment

If you think you’re experiencing symptoms of ADHD but haven’t been diagnosed, the best place to start is  talking to your primary care provider or a mental health professional.

Mental health disorders can be serious. It’s important to get an official diagnosis from a qualified provider. Online tools are useful for learning more about ADHD. But they can’t provide the official diagnosis you need to get treatment. 

Your first visit with a qualified provider may include a checklist of questions. You’ll share information about your health history and symptoms, especially any that were noticed before age 12. Your provider may recommend additional medical and psychological testing to help make an accurate diagnosis. These tests can also help determine the best treatment options for you.

A combination of therapy, such as cognitive-behavioral therapy, and medicine has been shown to be the most effective treatment option for adults with ADHD. There are also lifestyle changes that can be added to your treatment routine. All of these are aimed at helping you better manage symptoms and boost your coping skills.

Lifestyle options may include:

• Coaching from a life coach or an ADHD specialist.
• Starting an enjoyable exercise routine.
• Focusing on better sleep habits.
• Making diet changes to support your mood.
• Finding a support group.

It’s never too late to seek help for ADHD or any other mental health condition. Once diagnosed, getting the right treatment for you can make your daily life much easier. It can also help you grow in your relationships at work and at home with family.
