Attention-Deficit/Hyperactivity Disorder (ADHD)

About Attention-Deficit/Hyperactivity Disorder (ADHD)

Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder characterized by persistent patterns of inattention, hyperactivity, and impulsivity that interfere with daily executive functioning, learning, and social relationships.

Rather than a simple lack of effort or discipline, ADHD reflects underlying differences in brain regulation—specifically affecting executive function—and typically manifests across two primary symptom domains (or a combined presentation):

Inattention & Executive Dysfunction: Persistent difficulty sustaining focus on routine or low-stimulation tasks, frequent mental disorganization, forgetfulness in daily activities, trouble managing time, and poor working memory.

Hyperactivity & Impulsivity: Motor restlessness or inability to remain seated, feeling "driven by a motor," difficulty engaging in quiet activities, blurted answers, interrupting others, and acting or making decisions without considering consequences.

Emotional Dysregulation: High sensitivity to frustration, intense emotional reactions, and difficulty modulating arousal levels in response to daily stressors. While historically thought to be a chemical signaling issue primarily involving dopamine and norepinephrine, more recent research shows it is not a standalone behavioral disorder but a systemic symptom of brain asymmetry (hemisphericity) where the brain’s "braking system" struggles to sync with its "accelerator", which is paired with metabolic, gut, and nutritional imbalances.

Frequency: An estimated 12% of U.S. children aged 3 to 17—approximately 7 million kids—have a current diagnosis of ADHD. In addition, an estimated 6% of U.S. adults (roughly 15.5 million people) are actively living with a formal ADHD diagnosis.

Gender Differences: In children, boys are diagnosed roughly twice as often as girls. National data shows approximately 13% of boys have a current diagnosis compared to 7% of girls. More than half of adults with ADHD were diagnosed in adulthood (age 18 or older). This late-stage discovery occurs more frequently in women; 61% of women with ADHD do not receive their diagnosis until adulthood, compared to 40% of men.

Age of Onset: While the diagnosis can be made at any point, symptoms must be present before age 12. The average median age of diagnosis is 6 years old, though severe cases are routinely diagnosed as early as age 4.

Symptom Severity: Among children actively living with ADHD, 60% experience moderate or severe symptoms that significantly impair their schoolwork or social life. Longitudinal data from the National Institute of Mental Health (NIMH) shows that ADHD is not something most people simply "grow out of." Roughly 60% to 70% of children with ADHD continue to experience impairing symptoms as adults.

Co-Occurring Conditions: True "isolated" ADHD is rare. Approximately 78% of children and over 50% of adults with ADHD have at least one co-occurring mental health condition, most frequently anxiety, depression, or learning disorders.

Types and classifications

• Traditional healthcare diagnoses include two types of ADHD which are Hyperactive-Impulsive or Inattentive as described in more detail below:
• Predominantly Hyperactive-Impulsive Presentation: Characterized primarily by physical restlessness, fidgeting, excessive talking, and an inability to sit still, alongside impulsive actions like interrupting others or acting without considering consequences. Inattention is less pronounced.
• Predominantly Inattentive Presentation: Characterized primarily by difficulties sustaining focus, organizing tasks, following detailed instructions, and managing time. Hyperactivity is minimal or absent, and individuals are often described as daydreamers or easily distracted.
• Functional medicine and neurologists evaluate the physical performance, electrical activity, and pathway communication of the nervous system, often using neurological mapping to define types through key indicators like areas of brain asymmetry and persistent primitive reflexes:
• Hemispheric Imbalance: ADHD symptoms can stem from a hemispheric brain imbalance where one side is less active than the other, affecting timing, sensory processing, and impulse control. When the right side of the brain matures too slowly, it loses its ability to act as a "brake," leaving the individual struggling to pause, pay attention, or regulate impulses. Without this right-brain oversight, the left side runs in overdrive, triggering the rapid-fire mental and physical pacing typical of hyperactivity.
• Primitive Reflex Retention: Functional practitioners frequently find that children or adults with ADHD still retain infant reflexes (like the Moro or Asymmetrical Tonic Neck Reflex). These unintegrated reflexes keep the central nervous system stuck in a low-grade, hyper-reactive "fight-or-flight" loop, destroying focus
• Quantitative EEG (QEEG) Wave-Pattern Types
• Classic/Sluggish Type: Characterized by excessive slow frontal theta wave activity and a high theta-beta ratio, indicating an under-aroused cortex.
• Over-Focused Type: Characterized by excess frontal-central theta or alpha activity, where attention gets rigidly "stuck" instead of properly shifting.
• Limbic vs. Prefrontal Disconnection: Subtypes where deep emotional/limbic structures override the executive control of the prefrontal cortex, resulting in emotional dysregulation alongside inattention
