Understanding ADHD Across the Lifespan

Redefini Therapies: Evidence-informed assessment and support

ADHD is a neurodevelopmental condition involving differences in attention regulation, executive functioning, inhibition, motivation and emotional regulation. ADHD changes in how it presents across life, but it does not disappear with age.

Childhood: early years and primary school

  • Difficulty sustaining attention on tasks or activities

  • High activity levels or constant movement

  • Forgetting instructions and losing items

  • Emotional reactivity and low frustration tolerance

  • Difficulty waiting, taking turns or following routines

  • Challenges organising schoolwork and daily tasks

Adolescence: secondary school and teen years

  • Increased academic demands requiring sustained effort

  • Difficulties with organisation, planning and prioritising

  • Emotional intensity and heightened sensitivity

  • Significant time management difficulties

  • Sleep changes and irregular rhythms

  • Increased risk of anxiety, low self-esteem and burnout

Adulthood: work, relationships and daily life

  • Time blindness and difficulty estimating duration

  • Difficulty prioritising and completing multiple tasks

  • Chronic overwhelm and decision fatigue

  • Emotional dysregulation affecting relationships

  • Workplace and relationship challenges

  • Hyperfocus on highly motivating interests

Across the lifespan: what every person, family and professional should know

Not laziness. ADHD reflects genuine neurological differences, not a lack of effort or motivation.

Not a lack of intelligence. ADHD is unrelated to intellect. Many people with ADHD are highly capable and creative.

Often co-occurring. ADHD frequently co-occurs with autism, anxiety and learning differences such as dyslexia.

Support makes a difference. The right strategies, environment and clinical support can significantly improve quality of life.

Clinical takeaway: A thorough ADHD assessment should consider the person's developmental history, current functioning, strengths, executive functioning, emotional wellbeing and the environments in which difficulties occur, not just a symptom checklist.

Redefini Therapies provides comprehensive, evidence-informed ADHD assessments and practical recommendations across the lifespan.
