If you are new to ADHD, this guide walks through the basics in plain language. Let’s dive in!
What does ADHD stand for?
ADHD stands for Attention Deficit Hyperactivity Disorder.
The name can be a little misleading. It is not really a deficit of attention. It is more about how attention gets regulated.
People with ADHD can hyperfocus intensely on things that interest them. At the same time, they can struggle to direct attention toward things that do not interest them, even when those things matter. Think hyperfocusing on organizing the closet while ignoring paying the bills or answering important emails.
What is ADHD, exactly?
ADHD is one of the most common neurodevelopmental disorders. That means it is rooted in how the brain grows and develops, not a character flaw and not a result of parenting (Centers for Disease Control and Prevention [CDC], 2026a).
Symptoms usually start in childhood. They often continue into adulthood, though many adults, especially women, are not diagnosed until much later in life (CDC, 2026a).
What brain chemicals are involved?
Two neurotransmitters play the biggest role.
Dopamine. This chemical drives motivation, reward, and pleasure. In ADHD brains, dopamine is regulated differently, which makes it harder to sustain motivation for tasks that do not offer an immediate reward (ADDA, 2026; Harrington, 2024).
Norepinephrine. This chemical supports sustained attention and alertness. People with ADHD tend to have lower activity of both dopamine and norepinephrine in key brain regions, which makes it harder to filter distractions and stay on task (Harrington, 2024).
This is part of why stimulant medications can help. They are not sedating the brain. They are making more dopamine and norepinephrine available where the brain needs it (Harrington, 2024).
What part of the brain is involved?
The main region is the prefrontal cortex, sometimes called the brain's personality center. It sits right behind the forehead (Harrington, 2024).
ADHD also involves two other regions that work alongside the prefrontal cortex:
- The basal ganglia, which helps regulate communication within the brain
- The cerebellum, which is involved in movement and coordination
Together, these three regions manage attention, impulse control, and motor activity (Harrington, 2024).
What is executive function?
Executive function is the set of mental skills the prefrontal cortex handles. Think of it as the brain's management office.
These skills include:
- Planning and organizing
- Working memory, or holding information in mind while using it
- Impulse control
- Time awareness (many people with ADHD describe "time blindness," where time feels like it is either now or not now)
- Emotional regulation
- Task initiation and switching between tasks
In ADHD, these executive function skills are affected because of how the prefrontal cortex develops and communicates with other brain regions (Harrington, 2024).
What does ADHD impact?
ADHD can touch nearly any area where executive function is needed. That includes:
- School and work performance (this is separate from intelligence)
- Relationships, including forgetfulness and interrupting
- Time management and organization
- Emotional regulation
- Sleep patterns
- Self esteem, especially for people diagnosed later in life
What is the difference between ADD and ADHD?
There is no real difference anymore. ADD, or Attention Deficit Disorder without hyperactivity, was the term used before 1994.
Today everything falls under ADHD, with three presentations:
- Predominantly inattentive. This is what used to be called ADD. Think daydreamy and disorganized, without much hyperactivity.
- Predominantly hyperactive impulsive.
- Combined type. This is the most common presentation.
So if someone says they have ADD, they usually mean the inattentive type.
Are you doomed if you have ADHD?
No. ADHD is one of the most treatable conditions in mental health.
Many people do not just manage their ADHD. They build real strengths from it, including creativity, high energy, and the ability to hyperfocus, once they understand how their brain works and put the right systems in place.
Famous people and entrepreneurs with ADHD
Quite a few well known entrepreneurs and public figures have spoken openly about having ADHD, including:
- Richard Branson, founder of the Virgin Group, who has said his hyperactivity and impulsivity helped him take business risks and think creatively (UoPeople, 2025; Edge Foundation, n.d.)
- David Neeleman, founder of JetBlue Airways, who has spoken about how his ADHD fueled his vision and willingness to take risks (SUCCESS, 2024)
- Ingvar Kamprad, founder of IKEA, who adapted the way he ran his business to work with his ADHD and dyslexia (Edge Foundation, n.d.)
- Charles Schwab, founder of the Charles Schwab Corporation (Edge Foundation, n.d.)
- Simone Biles and Michael Phelps, Olympic athletes who have spoken publicly about their ADHD
- Mel Robbins, author and podcast host, who was diagnosed with ADHD at age 47 and now speaks openly about how it shaped her life and work (Robbins, 2023)
Many entrepreneurs describe traits like risk tolerance, comfort with novelty, and the ability to hyperfocus under pressure as genuine advantages in building a business.
How can you find out if you have it?
A proper diagnosis comes from a comprehensive assessment, usually done by a psychologist, psychiatrist, or a specially trained primary care provider.
This process typically includes:
- Structured interviews
- Standardized rating scales
- A look back at childhood history, since ADHD symptoms need to have shown up before age 12, even if the diagnosis happens much later (CDC, 2026b; Harrington, 2024)
Symptoms also need to affect more than one area of life, such as home, school, or work, and cannot be better explained by something else, like sleep deprivation or a thyroid condition (Harrington, 2024).
Some clinics also use computerized attention testing as an extra tool. Self screening questionnaires can be a helpful first step to decide whether a full assessment is worth pursuing, though they are not diagnostic on their own.
At Serebro Health, we cannot diagnose ADHD, but we make it easy to take the first step. Rather than searching for a self screening tool on your own, we can send one directly to you. Once you complete it, your therapist can walk through the results with you and start supporting the specific challenges you are facing, whether that is focus, organization, or emotional regulation.
What can you do about it?
Working with your therapist. Once you have a clearer picture of your patterns, therapy sessions can focus on building the executive function scaffolding that ADHD affects most. That might look like practical strategies for staying organized, tools for managing time and task initiation, and support for the emotional side of ADHD, including frustration, rejection sensitivity, and self esteem.
Medication. Stimulants, including methylphenidate and amphetamine based medications, are considered first line treatment for many people. Nonstimulant options are available for those who cannot tolerate stimulants or prefer not to take them. Medication is prescribed and monitored by a physician or psychiatrist, and often works well alongside therapy (CDC, 2024b; Harrington, 2024).
Coaching. ADHD coaches help build external systems and structure to support the executive function skills that ADHD affects.
Lifestyle supports. Regular exercise can raise dopamine and norepinephrine in ways similar to medication. Consistent sleep, hydration, and externalizing memory through lists and visible calendars also help (Harrington, 2024).
Self understanding. Many people say the biggest relief comes simply from understanding why their brain works the way it does. It can turn years of self blame into a clearer picture of how to work with their own wiring instead of against it.
