Deciding whether someone has Attention-Deficit/Hyperactivity Disorder (ADHD) is a detailed process that requires several steps. It’s important to understand that there isn’t a single test that can definitively diagnose ADHD. Many conditions, such as sleep problems, anxiety, depression, and learning disabilities, can present symptoms that overlap with ADHD, making a comprehensive evaluation crucial.
When to Seek Professional Guidance
If you have concerns about yourself or someone you know exhibiting symptoms of ADHD, the first step is to consult a healthcare provider to determine if these symptoms align with ADHD diagnostic criteria. A diagnosis of ADHD can be formally made by qualified mental health professionals, including psychologists and psychiatrists, or by primary care providers such as pediatricians. These professionals are trained to evaluate and differentiate ADHD from other conditions.
Diagnosing ADHD in Children: A Multi-Faceted Approach
For children, diagnosing ADHD involves a thorough evaluation to rule out other potential causes for their symptoms or conditions that may co-exist with ADHD. The American Academy of Pediatrics (AAP) guidelines1 recommend that healthcare providers gather information from multiple sources. This includes parents, teachers, and other adults involved in the child’s care, to understand the child’s behavior across different settings like home, school, and social interactions. This holistic approach ensures a comprehensive understanding of the child’s challenges.

Diagnosing ADHD in Adults: Recognizing Evolving Symptoms
ADHD is not solely a childhood condition; it often persists into adulthood. While the core symptoms remain, their presentation can change with age. For instance, hyperactivity in adults might manifest as extreme restlessness or a tendency to exhaust those around them with constant activity. Recognizing these evolving symptoms is key to accurate diagnosis in adults. Learn more about ADHD in adults to understand the nuances of adult ADHD.

The Role of DSM-5 Criteria in ADHD Diagnosis
Healthcare providers rely on the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5)2 as the standard guideline for diagnosing ADHD. These established diagnostic criteria ensure consistent and appropriate diagnosis and treatment of ADHD across different populations. Using a uniform standard also allows for accurate data collection to understand the prevalence of ADHD and its impact on public health.
Symptom Thresholds for ADHD Diagnosis Based on Age
The DSM-5 outlines specific symptom thresholds that need to be met for an ADHD diagnosis, which vary slightly based on age:
- For children up to 16 years old: Six or more symptoms of inattention and/or hyperactivity-impulsivity are required.
- For adolescents 17 years and older and adults: Five or more symptoms of inattention and/or hyperactivity-impulsivity are necessary for a diagnosis.
These symptoms must represent a persistent pattern of inattentionA and/or hyperactivityB–impulsivityC that demonstrably interferes with an individual’s functioning and development.
DSM-5 Diagnostic Criteria for ADHD: Key Symptoms
The DSM-5 criteria are provided below in an abbreviated format for informational purposes. It is crucial to remember that only qualified healthcare professionals can diagnose and treat ADHD. This information should not be used for self-diagnosis.
Inattention Symptoms
Diagnostic Note: Symptoms of inattention must have been present for at least 6 months and be inappropriate for the individual’s developmental age.
- Frequently overlooks details or makes careless errors in tasks.
- Struggles to sustain attention in tasks or play.
- Often appears not to listen when directly spoken to.
- Fails to follow through on instructions and duties (not due to defiance or lack of understanding).
- Has difficulty organizing tasks and activities.
- Avoids or dislikes tasks requiring sustained mental effort.
- Loses necessary items for tasks or activities (e.g., keys, school supplies).
- Easily distracted by extraneous stimuli.
- Forgetful in daily activities.
Hyperactivity-Impulsivity Symptoms
Diagnostic Note: Symptoms of hyperactivity-impulsivity must have been present for at least 6 months and be inappropriate for the individual’s developmental level.
- Fidgets or taps hands or feet, or squirms in seat.
- Leaves seat in situations when remaining seated is expected.
- Runs about or climbs in inappropriate situations (restlessness in adults).
- Unable to engage in leisure activities quietly.
- Often “on the go” or acts as if “driven by a motor.”
- Talks excessively.
- Blurts out answers before questions are completed.
- Difficulty waiting their turn.
- Interrupts or intrudes on others.
Additional Conditions for a Valid ADHD Diagnosis
In addition to meeting the symptom criteria, several other conditions must be satisfied for an accurate ADHD diagnosis:
- Several inattentive or hyperactive-impulsive symptoms were present before the age of 12.
- Symptoms are present in two or more settings (e.g., home, school, work, with friends).
- There is clear evidence that symptoms interfere with or reduce the quality of social, academic, or occupational functioning.
- Symptoms are not better explained by another mental disorder and do not occur exclusively during schizophrenia or another psychotic disorder. It’s important to rule out conditions like mood disorders, anxiety disorders, dissociative disorders, or personality disorders. Learn more about mental health disorders for further understanding.
