Deciding whether someone has Attention-Deficit/Hyperactivity Disorder (ADHD) is a detailed process involving several steps. It’s important to understand that there isn’t a single, definitive test for ADHD. Many conditions, including sleep disorders, anxiety, depression, and certain learning disabilities, can present symptoms that overlap with ADHD, making a thorough evaluation crucial.
When to Seek Professional Guidance for ADHD Concerns
If you have concerns about yourself or someone you know potentially having ADHD, the crucial first step is to consult with a healthcare professional. This initial consultation is to determine if the presented symptoms align with the criteria for an ADHD diagnosis. This diagnosis can be officially made by qualified mental health professionals such as psychologists or psychiatrists, or by primary care providers, including pediatricians for children and family doctors for adults. These professionals are trained to conduct comprehensive ADHD assessments.
ADHD Diagnosis in Children: A Multi-faceted Approach
When diagnosing ADHD in children, healthcare providers follow a structured approach. They will first rule out any other medical or psychological conditions that might better explain the observed symptoms or that frequently co-occur with ADHD. It’s important to consider that conditions like anxiety, learning disabilities, and even thyroid issues can sometimes mimic ADHD symptoms.
The American Academy of Pediatrics (AAP) provides clear recommendations1 for diagnosing ADHD in children. These guidelines emphasize the importance of gathering information from multiple sources. Healthcare providers should actively seek input from parents, teachers, and other adults who are regularly involved in the child’s life. This comprehensive approach helps to understand the child’s behavior across different settings, including home, school, and social interactions with peers. This multi-perspective assessment is vital for accurate diagnosis.

ADHD Diagnosis in Adults: Recognizing Evolving Symptoms
ADHD is not just a childhood condition; it often persists into adulthood. However, the way ADHD symptoms manifest can change as individuals age. For instance, hyperactivity in adults might not look like constant running and jumping as seen in children. Instead, it may present as extreme restlessness, difficulty relaxing, or even overwhelming others with high energy levels and constant activity. Understanding these varied presentations is key to accurate adult ADHD diagnosis. To learn more about the presentation of ADHD across different life stages, explore resources on ADHD in adults.
For extensive information on ADHD diagnosis and treatment throughout life, valuable resources are available from the National Resource Center on ADHD (NRC), a program of Children and Adults with Attention-Deficit/Hyperactivity Disorder (CHADD), and the National Institute of Mental Health (NIMH). These organizations offer comprehensive support and information for individuals and families affected by ADHD.
DSM-5: The Diagnostic Framework for ADHD
Healthcare professionals rely on the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5),2 published by the American Psychiatric Association, as the primary guidelines for diagnosing ADHD. The DSM-5 provides a standardized set of criteria that ensures consistent and appropriate diagnosis and treatment of ADHD. Using these uniform guidelines across different communities is also essential for public health purposes, helping to accurately track the prevalence of ADHD and understand its impact on public health.
Symptom Thresholds for ADHD Diagnosis Across Age Groups
The DSM-5 outlines specific criteria regarding the number of symptoms needed 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 criteria are designed to identify a persistent pattern of inattentionA and/or hyperactivity–impulsivityB–impulsivityC that significantly interferes with an individual’s daily functioning and development.
Detailed DSM-5 ADHD Diagnostic Criteria
The following are the shortened DSM-5 criteria for ADHD. It is important to remember that these are for informational purposes only. Only qualified healthcare providers are authorized to diagnose and treat ADHD.
Inattention Symptoms
Diagnostic Considerations: Symptoms of inattention must have been present for at least 6 months and must be inappropriate for the individual’s developmental level to be considered clinically significant.
- Frequently overlooks details or makes careless mistakes in schoolwork, work, or other activities.
- Often struggles to sustain attention in tasks or during play.
- Often appears not to listen when spoken to directly.
- Often fails to follow through on instructions and does not complete schoolwork, chores, or workplace duties (loses focus, gets sidetracked).
- Often has difficulty organizing tasks and activities.
- Often avoids, dislikes, or is reluctant to engage in tasks that require sustained mental effort (such as schoolwork or homework).
- Frequently loses essential items for tasks or activities (e.g., school materials, pencils, books, tools, wallets, keys, paperwork, eyeglasses, mobile phones).
- Is often easily distracted by extraneous stimuli.
- Is often forgetful in daily activities.
Hyperactivity-Impulsivity Symptoms
Diagnostic Considerations: Symptoms of hyperactivity-impulsivity must have been present for at least 6 months and be inappropriate for the person’s developmental level to be considered clinically significant for ADHD diagnosis.
- Often fidgets with or taps hands or feet, or squirms in their seat.
- Often leaves their seat in situations where remaining seated is expected.
- Often runs about or climbs in inappropriate situations (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 fully asked.
- Often has difficulty waiting their turn.
- Often interrupts or intrudes on others (e.g., butts into conversations or games).
Additional Conditions for ADHD Diagnosis
In addition to meeting the symptom criteria, several other conditions must be satisfied for an ADHD diagnosis:
- Age of Onset: Several inattentive or hyperactive-impulsive symptoms must have been present before the age of 12 years.
- Cross-Situational Symptoms: Symptoms must be present in two or more settings (e.g., at home, school, work, with friends or relatives, in extracurricular activities). This demonstrates that the symptoms are pervasive and not limited to a single environment.
- Significant Impairment: There must be clear evidence that the symptoms significantly interfere with or reduce the quality of social, academic, or occupational functioning. ADHD symptoms should have a noticeable negative impact on daily life.
- Exclusion of Other Disorders: The symptoms should not be better explained by another mental disorder. It’s crucial to rule out other conditions such as mood disorders, anxiety disorders, dissociative disorders, or personality disorders. Additionally, the symptoms should not occur exclusively during the course of schizophrenia or another psychotic disorder. Differential diagnosis is a critical part of the ADHD assessment process.
