Recognising ADHD and Autism in adults
Many adults with ADHD or Autism reach adulthood without ever receiving a formal assessment. If several of the experiences below sound familiar, assessment can provide clarity and open doors to the right support.
ADHD in adults
Adult ADHD is frequently missed — particularly in those who developed coping strategies early in life or excelled academically despite their difficulties.
- Persistent difficulty sustaining attention on tasks or conversations
- Frequently losing items, forgetting appointments or missing deadlines
- Acting impulsively — speaking without thinking or interrupting others
- Poor time management and a chronic sense of being behind
- Difficulty following through on tasks that require sustained effort
- Restlessness or an inner sense of being 'driven'
- Easily distracted by irrelevant thoughts or background stimulation
- Difficulties in relationships due to inattention or impulsive behaviour
Autism in adults
Many autistic adults were not identified in childhood — particularly women, and those who learned to conceal autistic traits in order to fit in socially.
- Difficulties navigating social situations or understanding unspoken rules
- Strong preference for routines and significant distress at unexpected change
- Intense, focused interests that absorb large amounts of time and energy
- Sensory sensitivities — to noise, light, texture, smell or crowds
- Difficulty interpreting facial expressions, tone of voice or social cues
- Feeling 'different' from others throughout life — having to mask to fit in
- Preferring clear, direct communication and finding ambiguity difficult
- Exhaustion following social interactions — needing time alone to recover
These experiences do not confirm a diagnosis. ADHD and Autism can only be confirmed through a formal clinical assessment. If you recognise several of these traits, speaking with a specialist is a sensible next step.
