ADHD

ADHD is related to differences in how the brain develops and manages attention, motivation and self-regulation. It is not caused by laziness, poor parenting or a lack of intelligence. It often runs in families, and genetics play a significant role.

Clinicians describe three main presentations:

• Predominantly inattentive ADHD: difficulty sustaining attention, organizing tasks and following through, without prominent hyperactivity. This was once called ADD, a term many people still use.
• Predominantly hyperactive-impulsive: restlessness, difficulty staying still and acting without thinking.
• Combined presentation: significant symptoms of both inattention and hyperactivity-impulsivity.

Presentations can change over time. Hyperactivity often becomes less visible in adults, appearing as inner restlessness instead. ADHD frequently occurs alongside other conditions, such as anxiety, depression, learning differences like dyslexia, and autism. Many people, especially women and girls, are diagnosed later in life because their symptoms were overlooked or masked.

ADHD symptoms vary in type and intensity. Common signs of inattention include:

• Difficulty focusing on tasks, especially ones that feel boring
• Making careless mistakes or overlooking details
• Trouble organizing tasks, time and belongings
• Frequently losing things or forgetting appointments
• Being easily distracted by thoughts or surroundings
• Starting tasks but not finishing them

Common signs of hyperactivity and impulsivity include:

• Fidgeting, squirming or feeling restless
• Difficulty sitting still or waiting
• Talking a lot or interrupting others
• Acting or speaking without thinking
• Difficulty with turn-taking or patience

Many people with ADHD also experience strong emotions, sensitivity to rejection, difficulty regulating mood and periods of intense focus, sometimes called hyperfocus, on things they find interesting. Everyone has some of these traits sometimes. ADHD is considered when symptoms are persistent, present in more than one setting and significantly affect school, work, relationships or daily functioning.

ADHD in children often becomes noticeable at school, where demands on attention and behavior increase. Children may struggle to follow instructions, complete work, sit still or manage frustration. Inattentive children, often girls, may be described as daydreamy and can be missed because they're not disruptive.

Parents and teachers may notice problems with friendships, low self-esteem or frequent conflicts. Early support at home and school can make a big difference.

In adults, ADHD may look like chronic disorganization, procrastination, difficulty managing time and money, restlessness, impulsive decisions and trouble keeping up at work. Many adults have developed coping strategies that hide their difficulties but leave them exhausted. Some only recognize their ADHD after a child is diagnosed or after years of feeling that they underperform despite effort.

Untreated ADHD can contribute to anxiety, depression, relationship strain and substance use. Recognizing it, at any age, can bring relief and open the door to effective support.

There is no single blood test or brain scan for ADHD. Online ADHD tests and questionnaires can help you reflect on symptoms, but they cannot provide a diagnosis.

A full ADHD assessment is carried out by a qualified professional, such as a psychiatrist, neuropsychologist, educational psychologist (for children) or another trained clinician. It typically includes:

• A detailed interview about current difficulties and how they affect daily life
• Questions about childhood, since symptoms usually begin early
• Standardized rating scales completed by you and, where possible, family, partners or teachers
• Screening for other conditions that can look similar or co-occur, such as anxiety, depression, sleep problems or learning differences
• For children, information from school and observation of behavior

Neuropsychological testing may be used to explore attention, memory and executive functioning. The process may take more than one appointment. The aim is to understand your strengths and difficulties, not just to apply a label.

ADHD treatment is usually most effective when it combines several approaches tailored to the person's age and needs.

ADHD medication, including stimulant and non-stimulant options, can reduce core symptoms for many people. It is prescribed and monitored by a psychiatrist or other qualified doctor, who will discuss benefits, possible side effects and how to adjust treatment. Medication isn't right for everyone, and the decision is made together with the clinician.

Psychological and practical support is also important:

• For children: parent training and behavioral approaches, along with school support and accommodations
• For adults: cognitive behavioral therapy (CBT) adapted for ADHD, which builds skills for organization, time management and coping with emotions
• ADHD coaching, which focuses on practical strategies and accountability
• Psychoeducation for individuals and families, to understand ADHD and reduce blame
• Support for co-occurring anxiety, depression or learning differences

Lifestyle factors, such as regular sleep, physical activity and structured routines, also help manage symptoms.

Depending on age and needs, a neuropsychologist, psychiatrist or educational psychologist can assess ADHD. Psychologists and therapists can support skills, emotions and relationships. At a first appointment, you'll be asked about symptoms, history and how ADHD affects your life. Bringing school reports or notes from family can be helpful.

While you wait for an assessment, try:

• Breaking tasks into small, concrete steps
• Using visual reminders, timers and calendars
• Creating routines and putting things in consistent places
• Working in short bursts with breaks
• Being kind to yourself; ADHD is not a character flaw
