Overview of Attention-Deficit/Hyperactivity Disorder
What Is Attention-Deficit/Hyperactivity Disorder (ADHD)?
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder that impacts how the brain develops and functions.
ADHD affects areas responsible for executive function, such as planning, organizing, and completing tasks. The condition is marked by a persistent pattern of inattention, hyperactivity, or impulsivity.
How Does ADHD Affect Mental Health and Daily Life?
ADHD contributes to depression, anxiety, low self-esteem, and executive dysfunction, which impairs work and school performance and relationships.
What Are Neurodevelopmental Disorders and How Does ADHD Fit Within Them?
Neurodevelopmental disorders are a group of conditions that start in childhood and affect the development and function of the brain.
ADHD is one of the most common neurodevelopmental disorders. It is chronic and often persists into adulthood.
How Does ADHD Impact Brain Development and Executive Functioning?
The area responsible for executive function may be smaller and develop more slowly, leading to delayed development that impedes daily tasks involving managing time, planning, and organizing.
What Is the DSM-5 Definition of ADHD?
ADHD is a persistent pattern of inattention and/or hyperactivity-impulsivity that interferes with functioning or development.
Youmust experience six or more persistent symptoms for at least six months and have a negative direct impact on social, academic, and or occupational activities for an ADHD diagnosis.
Types of ADHD
What Are the Different Types of ADHD?
There are three different types of ADHD: inattentive type, hyperactive/impulsive type, and combined type.
What Is Predominantly Inattentive ADHD?
Inattentive ADHD is characterized by difficulty sustaining focus, staying organized, and finishing tasks.
What Is Hyperactive-Impulsive ADHD?
Hyperactive-impulsive ADHD is characterized by difficulty sitting still, excessive talking, and impulsivity.
What Is Combined Type ADHD?
Combined type of ADHD is characterized by inattentive, hyperactive, and impulsive symptoms.
How Do Symptoms Differ Between Children, Adolescents, and Adults?
Behavioral symptoms are more obvious in childhood, emotional challenges are heightened in adolescents, and symptoms present as more executive dysfunction at work, school, and daily life in adulthood.
Prevalence and Statistics of ADHD
How Common Is ADHD Among Young Children, Adolescents, and Adults?
According to the Centers for Disease Control and Prevention (CDC), ADHD is diagnosed more in older children and adolescents, aged 12-17.
Approximately 1 in 9 children, aged 3-17, receive an ADHD diagnosis, while the CDC notes that around 1 in 16 adults has a current ADHD diagnosis.
What Is the Prevalence of ADHD According to the Centers for Disease Control and Prevention?
According to the CDC, an estimated 7 million (11.4%) children, aged 3-17, have been diagnosed with ADHD, and 15.5 million (6%) of adults, 18 and older, are living with ADHD.
How Does ADHD Prevalence Vary Across Demographics?
The prevalence of ADHD varies across gender, race, ethnicity, and age, with more underdiagnosed cases of ADHD among girls and minority groups.
Children from minority populations, such as Asian, Black, and Hispanic, are less likely to be diagnosed with ADHD compared to Non-Hispanic White children. Regarding gender, boys are more likely to be diagnosed with ADHD than girls due to differences and assumptions about symptom presentation.
Traditionally, ADHD has been more commonly diagnosed in children compared to adults due to the belief that ADHD is a childhood condition. DSM-5 updates in 1994 and 2013 have contributed to more adults receiving an ADHD diagnosis.
What Do National Reports From the National Institute of Mental Health Say About ADHD Rates?
The national reports statistics on ADHD rates from the National Institute of Mental Health (NIMH) state:
- Age of onset: age 7 for mild ADHD, age 6 for moderate ADHD, and age 4 for severe ADHD
- 11.0% of children aged 4-17 are diagnosed with ADHD
- Around one-third of children diagnosed with ADHD retain the diagnosis into adulthood
- 8.7% of adolescents aged 13-18 years have a ADHD diagnosis
- 4.4% of adults aged 18-44 have a current diagnosis of ADHD
Causes and Risk Factors of ADHD
What Causes ADHD?
There is no single cause of ADHD.
However, risk factors, such as genetics, environment, brain structure, and brain chemistry, can contribute to ADHD.
What Genetic and Biological Factors Contribute to ADHD?
Genetic and biological risk factors for ADHD include:
- Certain gene changes cause differences in brain development
- High heritability (genes are passed down)
- Higher risk of ADHD if a parent or sibling has ADHD
- Structural differences and reduced gray and white brain matter
- Chemical imbalances in dopamine and norepinephrine
- Personal or family history of other mental health conditions: anxiety, depression, bipolar disorder
What Environmental Factors Increase the Risk of ADHD?
Environmental risk factors for ADHD include:
- Exposure to heavy metals like lead and mercury
- Premature birth or low birth weight
- Substance use during pregnancy
- Extreme stress during pregnancy
- Childhood trauma, including poverty, abuse, and neglect
Does Low Birth Weight Increase the Risk of ADHD?
Yes. The lower the birth weight, the higher the risk of ADHD, regardless of other risk factors like genetics.
A low birth weight may contribute to ADHD because of disrupted brain development and increased vulnerability to other environmental, biological, and genetic risk factors.
How Does Brain Development Influence ADHD?
Brain development differences in brain structure, network, and chemistry can influence ADHD through delayed maturity, irregular connections, and chemical imbalance.
The frontal lobe experiences delayed maturity, which means the parts of the brain that manage organization, planning, attention, and decision-making, develop a few years later than neurotypical brains.
Connectivity challenges in the brain stem from an imbalance in the structure and function of groups of nerve cells called neurons. ADHD causes the networks to transmit messages less effectively because of overactive networks and irregular or weak connections.
Neurotransmitters help the brain and nervous system communicate with the rest of the body. However, ADHD causes a chemical imbalance that disrupts the brain’s ability to regulate neurotransmitters like dopamine and norepinephrine.
What Is the Role of Family History and Mental Health Conditions in ADHD Risk?
Family history is a risk factor for ADHD due to shared genes, while ADHD increases the risk for co-occurring mental health conditions due to the psychological impact of ADHD symptoms.

ADHD Diagnosis and Evaluation
How Is ADHD Diagnosed?
ADHD is diagnosed through several tests, from medical tests and clinical interviews to personal and academic history.
What Does an ADHD Diagnosis Involve?
An ADHD diagnosis starts with an initial screening to determine if you meet the criteria for ADHD symptoms, followed by a more comprehensive evaluation, which can include diagnostic interviews, behavior rating scales, and a medical exam.
What Role Do Healthcare Providers Play in Diagnosis?
Healthcare providers are the first point of contact for initial assessments, gathering pertinent medical and family history, ruling out other conditions, and coordinating care with mental health professionals.
What Criteria From the DSM-5 Are Used for ADHD Diagnosis?
The DSM-5 criteria you must meet for an ADHD diagnosis include:
- Six symptoms for children up to age 16 and five symptoms for adolescents and adults

What Are Common Side Effects of ADHD Medications?
Common side effects include decreased appetite, weight loss, difficulty sleeping, fatigue, tics, and changes in blood pressure and heart rate.
How Do FDA-Approved Medications Help Manage ADHD Symptoms?
ADHD medications increase dopamine and norepinephrine levels to support brain regulation, reducing impulsivity and improving attention, focus, motivation, and functioning.
