Diagnosing Attention-Deficit/Hyperactivity Disorder (ADHD) is a multifaceted process, requiring careful evaluation. It’s important to understand that there isn’t one single test for ADHD. Many conditions, such as sleep issues, anxiety disorders, depression, and learning disabilities, can present symptoms that overlap with ADHD, making a comprehensive assessment crucial for accurate diagnosis.
When to Seek Professional Advice for ADHD Concerns
If you have concerns about yourself or someone you know exhibiting potential ADHD symptoms, the crucial first step is to consult a healthcare provider to determine if these symptoms align with ADHD diagnostic criteria. An ADHD diagnosis can be made by qualified mental health professionals, including psychologists and psychiatrists, or by primary care providers like pediatricians and family doctors.
ADHD Diagnosis in Children: A Comprehensive Approach
When diagnosing ADHD in children, healthcare providers must rule out other conditions that might better explain the observed symptoms or conditions that frequently co-occur with ADHD.
The American Academy of Pediatrics (AAP) guidelines recommend that healthcare professionals gather information about a child’s behavior from multiple sources. This includes parents, teachers, and other adults involved in the child’s care, to understand behavior across different settings such as home, school, and social situations. For detailed recommendations on the diagnosis and treatment of ADHD in children and adolescents, further information is available here.

ADHD Diagnosis 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. Learn more about the nuances of ADHD in adults to better understand adult presentations.

DSM-5 Diagnostic Criteria for ADHD: A Closer Look
Healthcare professionals rely on the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) 2 as the standard guide for ADHD diagnosis. These established criteria ensure consistent and appropriate diagnosis and treatment of ADHD. Using a uniform diagnostic standard is also vital for public health research, helping to accurately determine the prevalence of ADHD within communities.
Symptom Thresholds for ADHD Diagnosis According to Age:
The DSM-5 outlines specific symptom thresholds based on age:
-
Six or more symptoms of inattention and/or hyperactivity-impulsivity are required for children up to 16 years old.
-
Five or more symptoms of inattention and/or hyperactivity-impulsivity are needed for adolescents 17 years and older, and adults.
Individuals with ADHD display a consistent pattern of inattentionA and/or hyperactivity-impulsivityC that negatively impacts their daily functioning and development.
Detailed DSM-5 Criteria for ADHD Diagnosis: Inattention and Hyperactivity-Impulsivity
The following are condensed versions of the DSM-5 criteria, intended for informational purposes only. Only qualified healthcare providers are authorized to diagnose and treat ADHD.
Inattention Symptoms
NOTE: Inattention symptoms must have been present for at least 6 months and be inappropriate for the individual’s developmental stage.
- Frequently overlooks details or makes careless mistakes in schoolwork, work, or other activities.
- Struggles to sustain attention in tasks or play activities.
- Appears not to listen when directly spoken to.
- Fails to follow through on instructions and doesn’t complete schoolwork, chores, or workplace duties (e.g., loses focus, gets sidetracked).
- Has difficulty organizing tasks and activities.
- Avoids, dislikes, or is reluctant to engage in tasks requiring sustained mental effort (like schoolwork or homework).
- Loses essential items for tasks or activities (e.g., school supplies, tools, wallets, keys, paperwork, phones, glasses).
- Is easily distracted by extraneous stimuli.
- Is often forgetful in daily routines.
Hyperactivity-Impulsivity Symptoms
NOTE: Hyperactivity-impulsivity symptoms must have been present for at least 6 months and be inappropriate for the person’s developmental stage.
- Fidgets or taps hands or feet, or squirms in their seat.
- Leaves seat in situations where remaining seated is expected.
- Runs about or climbs in inappropriate situations (in adolescents or adults, this may present as restlessness).
- Struggles to engage in leisure activities quietly.
- Is often “on the go,” acting as if “driven by a motor.”
- Talks excessively.
- Blurts out answers before questions have been completed.
- Has difficulty waiting their turn.
- Interrupts or intrudes on others (e.g., butts into conversations or games).
Additional Conditions for ADHD Diagnosis
Beyond the 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., home, school, work, with friends, relatives, or in other activities).
- There is clear evidence that symptoms significantly interfere with or reduce the quality of social, academic, or occupational functioning.
- Symptoms are not better explained by another mental disorder (such as mood disorders, anxiety disorders, dissociative disorders, or personality disorders). The symptoms should not occur solely during the course of schizophrenia or another psychotic disorder.
