Deciding whether someone has Attention-Deficit/Hyperactivity Disorder (ADHD) is a detailed process that requires several steps. It’s important to know that there isn’t a single, straightforward test to diagnose ADHD. Many conditions, such as sleep disorders, anxiety, depression, and certain learning disabilities, can present symptoms that overlap with ADHD, making accurate diagnosis crucial.
When Should You Seek Professional Advice for ADHD Diagnosis?
If you have concerns about yourself or someone you know exhibiting potential ADHD symptoms, the first step is to consult a healthcare provider. They can initially assess whether the symptoms align with an ADHD diagnosis. An ADHD diagnosis is typically made by qualified mental health professionals such as psychologists or psychiatrists, or by primary care providers, including pediatricians. These professionals are trained to differentiate ADHD from other conditions and provide accurate assessments.
Diagnosing ADHD in Children: A Multifaceted Approach
For children, diagnosing ADHD involves a comprehensive evaluation to rule out other conditions that might better explain the observed symptoms or co-exist with ADHD. The American Academy of Pediatrics (AAP) guidelines recommend that healthcare providers gather information from multiple sources. This includes input from parents, teachers, and other adults who are significant in the child’s life. These insights help to understand the child’s behavior across different environments like home, school, and social settings. For more detailed recommendations, you can explore further information on the diagnosis and treatment of children and adolescents with ADHD.

Diagnosing ADHD in Adults: Recognizing Evolving Symptoms
It’s important to recognize that ADHD often persists into adulthood, although symptom presentation can change over time. For instance, hyperactivity in adults might manifest as extreme restlessness or a tendency to exhaust those around them with constant activity rather than the overt physical hyperactivity seen in children. To gain a deeper understanding, resources are available on ADHD in adults.
For comprehensive information on ADHD diagnosis and management throughout life, the National Resource Center on ADHD and the National Institute of Mental Health websites are valuable resources.
DSM-5 Criteria: The Diagnostic Standard for ADHD
Healthcare professionals rely on the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5)2 as the standard guideline for diagnosing ADHD. These criteria are essential for ensuring consistent and appropriate diagnosis and treatment of ADHD across different populations. Using a standardized diagnostic approach also aids in gathering accurate prevalence data and understanding the public health impact of ADHD.
Symptom Thresholds for ADHD Diagnosis Based on Age
The DSM-5 outlines specific criteria based on age to determine an ADHD diagnosis:
- For children up to 16 years old: Diagnosis requires the presence of six or more symptoms of inattention and/or hyperactivity-impulsivity.
- For adolescents 17 years and older and adults: Diagnosis requires the presence of five or more symptoms of inattention and/or hyperactivity-impulsivity.
It’s important to remember that these symptoms must represent a persistent pattern of inattentionA and/or hyperactivityB–impulsivityC that significantly impairs daily functioning or development.
Detailed DSM-5 Criteria for ADHD Diagnosis
The following are the condensed DSM-5 criteria for informational purposes. It is critical to understand that only qualified healthcare providers can officially diagnose and manage ADHD.
Inattention Symptoms:
Symptoms of inattention must have persisted for at least 6 months and be inappropriate for the developmental level.
- Frequently fails to pay close attention to details or makes careless mistakes in schoolwork, work, or other activities.
- Often has difficulty sustaining attention in tasks or play activities.
- Often does not seem to listen when spoken to directly.
- Often does not follow through on instructions and fails to finish schoolwork, chores, or workplace duties (e.g., loses focus, gets sidetracked).
- Often has trouble organizing tasks and activities.
- Often avoids, dislikes, or is reluctant to engage in tasks that require sustained mental effort (such as schoolwork or homework).
- Often loses essential items for tasks or activities (e.g., school materials, pencils, books, tools, wallets, keys, paperwork, eyeglasses, mobile phones).
- Is frequently easily distracted by extraneous stimuli.
- Is often forgetful in daily activities.
Hyperactivity-Impulsivity Symptoms:
Symptoms of hyperactivity-impulsivity must have been present for at least 6 months and are inappropriate for the person’s developmental level.
- Often fidgets with or taps hands or feet, or squirms in seat.
- Often leaves seat in situations where remaining seated is expected.
- Often runs about or climbs in situations where it is inappropriate (in adolescents or adults, this may manifest as feeling restless).
- Often unable to play or engage in leisure activities quietly.
- Is frequently “on the go” or acts as if “driven by a motor.”
- Often talks excessively.
- Often blurts out an answer before a question has been completed.
- Often has difficulty waiting their turn.
- Often interrupts or intrudes on others (e.g., butts into conversations or games).
Additional Conditions for ADHD Diagnosis
Beyond symptom criteria, these conditions must also be met for an ADHD diagnosis:
- Several inattentive or hyperactive-impulsive symptoms were present before the age of 12 years.
- Symptoms are present in two or more settings (e.g., at home, school, work, with friends or relatives, in other activities).
- There is clear evidence that the symptoms significantly interfere with or reduce the quality of social, academic, or occupational functioning.
- The symptoms are not better explained by another mental disorder (such as mood disorders, anxiety disorders, dissociative disorders, or personality disorders) and do not occur exclusively during the course of schizophrenia or another psychotic disorder.
