Attention-Deficit/
Hyperactivity Disorder (ADHD)
ADHD is a neurodevelopmental condition that affects attention, impulse control, activity level, and executive functioning. This page explains what ADHD is, how it commonly shows up in children, and what families should understand as symptoms change over time.

What is attention-deficit/hyperactivity disorder?
Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental condition that affects how a person pays attention, controls impulses, regulates activity level, and manages executive functioning skills such as planning, organization, and time management.
Medical and public-health organizations describe ADHD as:
- A developmental condition that usually begins in childhood
- Often recognized when children enter school or structured learning environments
- Characterized by persistent patterns of:
- Inattention
- Hyperactivity
- Impulsivity (in different combinations)
ADHD is not caused by laziness, lack of intelligence, or poor parenting. It is a biologically based condition influenced by genetics and brain development. Many people continue to experience symptoms into adolescence and adulthood, though how symptoms appear may change over time.
What are common signs of ADHD in children?
Medical guidelines group symptoms into three areas:
A. Inattention
Possible signs include:
- Difficulty sustaining attention during tasks or play
- Frequently making careless mistakes or missing details
- Seeming not to listen when spoken to directly
- Trouble following through on instructions or finishing tasks
- Avoiding or strongly disliking tasks that require sustained mental effort (homework, reading)
- Losing things often (pencils, toys, books, homework)
- Being easily distracted by unrelated sights or sounds
- Forgetting daily activities or responsibilities
B. Hyperactivity
Possible signs include:
- Constant fidgeting, tapping hands or feet, or squirming
- Difficulty remaining seated when expected
- Running, climbing, or moving excessively in inappropriate situations
- Difficulty playing or engaging in activities quietly
- Talking excessively
- Appearing to be always on the go or driven by a motor
C. Impulsivity
Possible signs include:
- Blurting out answers before questions are finished
- Difficulty waiting for their turn
- Interrupting or intruding on others’ conversations or activities
- Acting without thinking about consequences
- Difficulty controlling emotional reactions (quick frustration, anger, or excitement)
Doctors use standardized criteria (DSM-5) to diagnose ADHD based on persistent symptoms that interfere with daily functioning in more than one setting (for example, home and school).
When do signs often show up? (approximate)
A. Preschool years (ages 3–5)
- Very high activity level compared to peers
- Difficulty following simple routines or directions
- Short attention span, even for preferred activities
- Frequent emotional outbursts or impulsive behavior
B. Elementary school years (ages 5–11)
- Difficulty sitting still or focusing in class
- Trouble completing assignments
- Frequent teacher concerns about attention or behavior
- Academic struggles despite average or high intelligence
C. Later childhood and adolescence (12 and older)
- Ongoing problems with organization, time management, and planning
- Difficulty keeping up with schoolwork
- Emotional dysregulation, low self-esteem, or frustration
- Impulsivity that may affect friendships or decision-making
Having some of these behaviors occasionally is normal. ADHD is considered when symptoms are frequent, persistent, and significantly interfere with daily life.
What should I do if I think my child has ADHD?
A. Screening and evaluation
Pediatric and mental-health guidelines recommend evaluation whenever parents, teachers, or clinicians have concerns.
Steps usually include:
- Developmental and behavioral screening
- Questionnaires completed by parents and teachers
- Focus on attention, behavior, emotional regulation, and executive functioning
- Comprehensive evaluation
- A child may be evaluated by:
- A pediatrician with experience in ADHD
- A developmental-behavioral pediatrician
- A child psychologist or psychiatrist
- A neurologist (in some cases)
- Evaluations typically include:
- Detailed developmental, medical, and family history
- Reports from school (teacher questionnaires, report cards)
- Observation of behavior
- Screening for learning differences, anxiety, or mood disorders
- A child may be evaluated by:
B. Diagnosis
To receive a diagnosis of ADHD under DSM-5, a child must have:
- Persistent symptoms of inattention and/or hyperactivity-impulsivity
- Symptoms present before age 12
- Symptoms occurring in two or more settings (home, school, activities)
- Clear evidence that symptoms interfere with academic, social, or daily functioning
- Symptoms not better explained by another condition
C. Intervention and support
There is no cure for ADHD, but evidence-based supports are effective. Treatment is individualized and may include:
- Behavioral interventions
- Parent training programs that teach strategies for structure, consistency, and positive reinforcement
- Classroom behavior supports and accommodations
- Skill-building for organization, time management, and emotional regulation
- Educational supports
- Individualized Education Programs (IEPs) or 504 plans
- Classroom accommodations such as:
- Extended time on tests
- Preferential seating
- Reduced homework load
- Organizational supports
- Therapy
- Cognitive behavioral therapy (CBT), especially for older children and teens
- Coaching for executive functioning skills
- Medication (when appropriate)
- Stimulant or non-stimulant medications may be prescribed
- Medications are used to reduce core symptoms, not to change personality
- Decisions are made collaboratively with families and monitored closely by clinicians
What else should I know?
A. ADHD looks different in different children
Some children are primarily inattentive, others are primarily hyperactive-impulsive, and many have a combined presentation.
B. ADHD is not caused by poor parenting
Parenting style does not cause ADHD, though supportive strategies can help manage symptoms.
C. Strengths are common
Many people with ADHD show:
- Creativity and original thinking
- High energy and enthusiasm
- Strong problem-solving skills
- Hyperfocus on topics of interest
D. Co-occurring conditions are common
Children with ADHD may also have:
- Learning disabilities
- Anxiety or depression
- Autism spectrum disorder
- Sleep difficulties
- Oppositional behaviors
E. Early support matters
Early identification and support can improve:
- Academic outcomes
- Emotional well-being
- Self-esteem
- Family functioning
What can I do to help my child right now?
Step 1. Trust your observations
Parents are often the first to notice attention or regulation differences.
Step 2. Talk to your child’s pediatrician
- Bring specific examples from home and school
- Ask directly for an ADHD evaluation if concerns persist
Step 3. Request school support
Parents can request a formal evaluation through their school district to determine eligibility for accommodations or services.
Step 4. Use supportive daily routines
- Use predictable schedules
- Break tasks into small, manageable steps
- Use visual schedules and checklists
- Provide frequent positive feedback
- Build in movement breaks
Step 5. Learn your child’s rights
- Understand IEPs, 504 plans, and school-based supports
- Keep records of evaluations and meetings
Step 6. Take care of yourself, too
Many families benefit from parent support groups and counseling to reduce stress and isolation.
