Key Takeaways
- •ADHD affects approximately 11% of U.S. children aged 3–17 and an estimated 4.4% of adults, making it one of the most prevalent neurodevelopmental conditions.
- •ADHD presents in three ways: predominantly inattentive, predominantly hyperactive-impulsive, or combined — adults more often present with inattentive symptoms.
- •Many adults with ADHD were never diagnosed as children, particularly women and girls who tend to present with less visible symptoms.
- •ADHD is highly treatable: a combination of behavioral therapy and medication produces significantly better outcomes than medication alone.
- •ADHD is not a problem of intelligence or effort — it's a difference in how the brain regulates attention, impulse control, and executive function.
What is ADHD and What Are The Symptoms?
Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder that affects individuals of all ages. According to the Centers for Disease Control and Prevention (CDC), ADHD is one of the most common neurodevelopmental disorders of childhood, affecting approximately 6.1 million children in the United States alone. However, it is important to note that ADHD can also affect adults.
ADHD is characterized by a persistent pattern of inattention, hyperactivity, and/or impulsivity that interferes with daily life. Symptoms of ADHD can vary widely, but may include:
If you suspect that you or someone you know may have ADHD, it is important to seek out professional help. A healthcare provider can help diagnose ADHD and provide treatment options, which may include medication, therapy, or lifestyle changes.
To help determine if you may have ADHD,
- •Difficulty paying attention or staying focused on tasks
- •Hyperactivity or restlessness, such as fidgeting or squirming
- •Impulsivity, such as interrupting others or acting without thinking
- •Forgetfulness or disorganization
- •Difficulty with time management or planning
- •Poor impulse control, such as overeating or substance abuse
What the science says
The CDC reports ADHD affects approximately 11% of U.S. children and 4.4% of adults. A 2021 meta-analysis in Neuroscience & Biobehavioral Reviews found that cognitive behavioral therapy (CBT) combined with medication produces significantly better long-term outcomes for adult ADHD than medication alone.
If you suspect ADHD, a licensed clinician — not a screening quiz — is the right next step for a formal evaluation.
