What is ADHD?
ADHD is a neurodevelopmental condition affecting attention, impulse control, and activity levels. It can influence daily life, school performance, work, and relationships.
What does ADHD mean?
ADHD, or Attention-Deficit/Hyperactivity Disorder, is a condition marked by patterns of inattention, hyperactivity, and impulsivity. These behaviors are more intense and frequent than typical age-related restlessness, making everyday tasks and focus challenging.
The main traits of ADHD include:
- Inattention: difficulty sustaining focus, forgetfulness, and disorganization
- Hyperactivity: constant movement, fidgeting, and difficulty remaining seated
- Impulsivity: acting without thinking, interrupting conversations, or making risky choices
What is ADHD
What is the full form of ADHD?
The full form of ADHD is Attention-Deficit/Hyperactivity Disorder, describing the combination of attention challenges, hyperactivity, and impulsive behaviors. This term is widely used in psychology and healthcare for diagnosis and treatment planning.Prevalence and who is commonly affected (children vs adults)
ADHD typically begins in childhood and is one of the more common childhood disorders. While boys are more often diagnosed in early years, many adults continue to experience symptoms. Some people are only recognized later in life—when challenges with work, relationships, or daily organization become more noticeable.
ADHD in children
Children with ADHD display behaviors that can affect learning, social interactions, and overall development.
What is ADHD in children — typical symptoms and school impact
Common signs include difficulty following instructions, restlessness, forgetfulness, and frequent daydreaming. These behaviors can impact academic performance, classroom behavior, and relationships with peers and teachers, making early identification crucial.How ADHD symptoms can look different by age and gender
Younger children often show noticeable hyperactivity, while older children may appear more inattentive or disorganized. Boys tend to display more externalized behaviors, whereas girls often show subtler symptoms like daydreaming, forgetfulness, or difficulty organizing tasks.
ADHD in adults:
ADHD continues into adulthood for many, often presenting differently than in children.
What is ADHD in adults — common adult presentations and challenges
Adults with ADHD may struggle with planning, time management, completing tasks, and maintaining focus. Impulsive decision-making and forgetfulness can affect careers, personal finances, and social relationships, often requiring targeted coping strategies.Work, relationships, and daily functioning impact
ADHD in adults can interfere with daily life, making tasks like meeting deadlines, organizing schedules, and maintaining relationships more difficult. Recognizing patterns early and seeking professional support can help improve functioning and quality of life.
How ADHD is viewed in psychology and diagnostics
Psychology provides frameworks for understanding ADHD and its impact on behavior, cognition, and daily functioning.
What is ADHD in psychology — clinical framework and models
In psychology, ADHD is seen as a neurodevelopmental disorder involving brain regions responsible for attention, executive function, and impulse control. Mental health professionals assess symptoms across multiple settings to ensure accurate diagnosis and personalized treatment.DSM-5 presentations (inattentive / hyperactive-impulsive / combined)
The DSM-5 identifies three main ADHD presentations:
- Predominantly inattentive: difficulties with focus and organization
- Predominantly hyperactive-impulsive: excessive movement and impulsive behavior
- Combined presentation: features of both inattentive and hyperactive-impulsive types
Symptoms must persist for at least six months and impair functioning in more than one setting for diagnosis.
How ADHD is diagnosed — step-by-step (clinician process)
Diagnosis of ADHD involves careful evaluation by a qualified professional. Understanding the steps helps parents, adults, and caregivers know what to expect during the assessment.
Initial screening: history, rating scales, and red flags
Clinicians start by reviewing personal, developmental, and family history. They often use rating scales completed by parents, teachers, or the adult themselves to identify patterns of inattention, hyperactivity, or impulsivity. Early red flags guide the need for a full evaluation.
Diagnostic criteria and differential diagnosis (DSM-5 highlights)
Diagnosis relies on DSM-5 criteria, which require symptoms to be present for at least six months and across multiple settings. Clinicians rule out other conditions, such as anxiety, depression, or learning disorders, to confirm that the behaviors are due to ADHD.Assessment differences: Children vs Adults
Children’s evaluations often include school reports and teacher feedback to understand classroom functioning. Adult assessments focus on work history, daily routines, and self-reported challenges, highlighting how ADHD manifests differently across life stages.
Tests, rating scales & common clinical tools
Various tools help quantify ADHD symptoms and track severity over time.
Parent/teacher/adult rating scales are often used in assessment
Standardized rating scales, such as the Conners Rating Scale or ADHD Rating Scale, are widely used. Parents, teachers, and adults provide structured input to identify inattentive, hyperactive, and impulsive behaviors objectively.When to involve specialists (psychiatrist, neurodevelopmental clinic)
If symptoms are complex, severe, or accompanied by co-occurring conditions, referrals to psychiatrists or neurodevelopmental clinics may be recommended. Specialists can provide medication evaluation, advanced testing, or integrated care plans.
Causes, risk factors & contributing issues
ADHD arises from a mix of genetic, biological, and environmental influences that interact in complex ways.
Genetic and neurobiological contributors
ADHD often runs in families, indicating a strong genetic component. Brain imaging studies show differences in areas controlling attention, executive function, and impulse regulation, explaining some of the observed behavioral patterns.Environmental, developmental, and co-occurring conditions
Factors such as prenatal exposure to toxins, premature birth, and early childhood adversity can contribute. Co-occurring conditions like anxiety, learning disorders, or sleep difficulties often complicate ADHD management.
Treatment overview & management strategies
Effective ADHD management combines therapies, medication, and practical supports to improve functioning and quality of life.
Treatments: behavioural therapies and medication
Behavioral therapies, including cognitive-behavioral therapy (CBT) and parent training, help develop coping skills. Medications such as stimulants and non-stimulants can improve attention, reduce hyperactivity, and support long-term symptom control.Practical supports: school plans, workplace accommodations, coaching
Individualized education plans (IEPs), workplace adjustments, and ADHD coaching can help manage daily challenges. Structured routines, reminders, and task breakdowns improve productivity and reduce stress.
Living well with ADHD — daily strategies
Long-term management focuses on building habits and support systems to thrive despite ADHD symptoms.
Organization, routines, and executive-function supports
Using calendars, checklists, and timers helps with time management. Breaking tasks into smaller steps, minimizing distractions, and setting consistent routines improve executive-function skills for both children and adults.
When to seek ongoing care and crisis planning
Regular follow-ups with clinicians ensure treatment effectiveness and symptom monitoring. Seek immediate support if ADHD Attention-Deficit Hyperactivity Disorder symptoms worsen, affect safety, or co-occur with severe anxiety, depression, or impulsive behaviors.
