What is ADHD?

Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental condition that affects how individuals focus, regulate behavior, and manage daily tasks. While it is commonly diagnosed in childhood, many individuals continue to experience symptoms into adulthood—and some are not diagnosed until later in life.

People with ADHD may find it challenging to maintain attention, stay organized, or follow through on responsibilities. They may also experience restlessness, impulsivity, or become easily distracted.

According to the Centers for Disease Control and Prevention (CDC), approximately 11.4% of children in the United States—about 7 million individuals ages 3–17—have been diagnosed with ADHD. The National Institute of Mental Health (NIMH) estimates that about 4.4% of U.S. adults are affected, though many remain undiagnosed. ADHD is more frequently identified in boys; however, it is often underrecognized in girls and women, leading to delayed diagnosis.

Types of ADHD

ADHD is categorized into three primary presentations based on symptom patterns:

Inattentive Presentation
Individuals primarily experience difficulty with focus, organization, and follow-through. They may appear forgetful, easily distracted, or struggle with completing tasks and maintaining attention in conversations.

Hyperactive-Impulsive Presentation
This presentation is characterized by restlessness, impulsivity, and difficulty remaining still. Individuals may interrupt others, talk excessively, or act without considering consequences.

Combined Presentation
The most common type, involving a combination of inattentive and hyperactive-impulsive symptoms.

Signs and Symptoms in Children

In children, ADHD may impact school performance, behavior, and social interactions. Common signs include:

  • Difficulty sustaining attention and making frequent careless mistakes

  • Forgetfulness with tasks such as homework or chores

  • Trouble organizing activities or managing time

  • Avoidance of tasks requiring prolonged focus

  • Fidgeting, restlessness, or excessive movement

  • Talking excessively or interrupting others

  • Difficulty waiting their turn

  • Impulsive or risky behaviors

  • Challenges completing tasks or following instructions

  • Difficulty maintaining friendships

  • Irritability, frustration, or mood swings

Signs and Symptoms in Adults

ADHD often continues into adulthood, though symptoms may present differently. Common challenges include:

  • Difficulty concentrating during conversations, meetings, or reading

  • Becoming easily distracted or overwhelmed

  • Poor time management, chronic lateness, or missed deadlines

  • Forgetfulness in daily responsibilities

  • Disorganization in personal or professional settings

  • Restlessness or difficulty relaxing

  • Impulsive decision-making (e.g., spending, interrupting, risk-taking)

  • Challenges in maintaining relationships

  • Low frustration tolerance or mood fluctuations

  • Chronic stress, procrastination, or underperformance

ADHD in Girls and Women

ADHD in girls and women is often underdiagnosed because symptoms may be more subtle or internalized. Rather than outward hyperactivity, individuals may experience:

  • Difficulty focusing and frequent distraction

  • Disorganization and forgetfulness

  • Emotional sensitivity and mood fluctuations

  • Feelings of overwhelm or low self-esteem

  • Internal restlessness or anxiety

  • Perfectionism or overcompensation

  • Masking symptoms to meet expectations

  • Challenges with social interactions or relationships

Evaluation and Diagnosis

Diagnosing ADHD involves a comprehensive evaluation by a qualified healthcare provider. This process may include:

  • Clinical interviews and medical history review

  • Behavioral assessments and standardized rating scales

  • Input from parents, teachers, or family members

  • Psychological testing when appropriate

  • Ruling out other medical or mental health conditions

For adults, diagnosis may also include self-report tools and a review of lifelong patterns of symptoms.

Causes of ADHD

ADHD is believed to result from a combination of factors, including:

  • Genetics: ADHD often runs in families

  • Brain development and function: Differences in areas responsible for attention and impulse control

  • Environmental influences: Prenatal exposures, premature birth, or toxin exposure

  • Psychosocial factors: Early life stress or trauma

Treatment for ADHD

Effective ADHD treatment is personalized and may include a combination of:

  • Therapy: Cognitive Behavioral Therapy (CBT), coaching, or parent training

  • Medication: Stimulant or non-stimulant options when appropriate

  • Educational support: IEPs, 504 plans, or classroom interventions

  • Lifestyle strategies: Regular exercise, balanced nutrition, quality sleep, and mindfulness practices
