What is ADHD? A Guide to Understanding Attention-Deficit/Hyperactivity Disorder

Attention Deficit Hyperactivity Disorder (ADHD) is one of the most commonly diagnosed neurodevelopmental disorders, affecting both children and adults. It’s often misunderstood as simply being “hyper” or having trouble paying attention, but ADHD is much more than that. It’s a complex condition that affects how the brain processes information, regulates attention, and controls impulses.

Let’s break down what ADHD really is, its symptoms, causes, and the most effective ways to manage it. We’ll also provide links to scientific studies so you can dive deeper into the research.

What Are the Symptoms of ADHD?

ADHD isn’t just about being easily distracted—it’s a pattern of behaviors that persist over time and interfere with daily life. The condition is typically divided into three types based on symptom presentation:

1. Inattentive Type (Previously Called ADD)

People with this type struggle with:

• Staying focused on tasks (especially ones they find boring or repetitive)
• Following through on instructions or finishing projects
• Organizing tasks and managing time effectively
• Losing track of belongings (keys, wallets, notebooks—gone in seconds!)
• Being easily distracted by noises, thoughts, or movement
• Forgetting appointments, deadlines, or even conversations

2. Hyperactive-Impulsive Type

This type is marked by:

• Constant fidgeting, tapping, or moving (like they’re driven by a motor)
• Difficulty staying seated for long periods (think school or work meetings)
• Talking excessively and blurting out thoughts before thinking
• Interrupting others or struggling to wait their turn in conversations
• Acting impulsively without considering consequences

3. Combined Type

Many people have a mix of inattentive and hyperactive-impulsive symptoms, which is called Combined Presentation ADHD. This is the most common form of ADHD.

Who Gets ADHD?

ADHD isn’t just a childhood disorder—while it’s often diagnosed in kids, about 60-70% of children with ADHD continue to have symptoms as adults (National Institute of Mental Health). It affects about 6-9% of children and 2-6% of adults worldwide.

ADHD is also more commonly diagnosed in boys than girls, but that doesn’t mean girls don’t have it. Girls with ADHD often go undiagnosed because they tend to show more inattentive symptoms rather than hyperactivity. Instead of being disruptive, they might be labeled as “daydreamers” or “easily distracted,” leading to delayed diagnosis.

What Causes ADHD?

There’s no single cause of ADHD, but research suggests it’s a mix of genetics, brain differences, and environmental factors.

1. Genetics

ADHD tends to run in families. Studies show that if a child has ADHD, there’s a 74-91% chance that at least one biological parent also has it. Scientists have linked ADHD to certain genes that affect how the brain regulates dopamine, a neurotransmitter involved in motivation and attention.

2. Brain Structure & Function

Brain imaging studies reveal key differences in the brains of people with ADHD:

• The prefrontal cortex, responsible for decision-making and impulse control, tends to develop more slowly.
• The basal ganglia, which helps regulate movement and attention, functions differently.
• The default mode network (DMN)—which controls focus and shifting attention—is less active when people with ADHD are trying to concentrate.

3. Environmental Factors

Certain environmental influences may contribute to ADHD, such as:

• Prenatal exposure to tobacco smoke, alcohol, or high levels of stress during pregnancy
• Premature birth or low birth weight
• Lead exposure in early childhood 

It’s important to note that ADHD is NOT caused by bad parenting, too much sugar, or watching too much TV—these are myths that have been debunked.

How is ADHD Treated? Neurofeedback: A Promising ADHD Treatment

An innovative approach to managing ADHD is neurofeedback, a type of brain training that helps individuals regulate their own brainwave activity. This therapy uses real-time monitoring of brain activity to teach self-regulation techniques, potentially improving focus, impulse control, and cognitive function.

Neurofeedback has been studied extensively for its effectiveness in treating ADHD. A meta-analysis published in European Child & Adolescent Psychiatry found that neurofeedback led to significant improvements in attention and impulse control, with effects comparable to stimulant medications.

Another study in Applied Psychophysiology and Biofeedback reported that children who underwent neurofeedback training showed lasting improvements in ADHD symptoms, even six months after treatment ended.

While neurofeedback is not a one-size-fits-all solution, it offers a non-invasive and medication-free way to help manage ADHD. If you’re interested in learning more, MaxWell Clinic offers neurofeedback assessments and personalized treatment plans to help patients optimize their brain function.

Living with ADHD

ADHD isn’t just about challenges—it also comes with strengths. Many people with ADHD are highly creative, energetic, and resilient. With the right strategies and support, people with ADHD can thrive in school, work, and life.

If you or a loved one suspect ADHD, seeking a professional evaluation is the first step. At MaxWell Clinic, we offer QEEG brain mapping to gain deeper insight into the unique patterns of brain activity associated with ADHD. This advanced assessment helps identify which areas of the brain may be underactive or dysregulated, providing a roadmap for personalized treatment. Based on these findings, Neurofeedback therapy can be used to help train the brain to function more efficiently, improving focus, impulse control, and overall cognitive performance.
