What is autism (ASD)?
Autism spectrum disorder (ASD) is a lifelong neurodevelopmental difference that shapes how a person perceives the world, communicates, relates to others and processes sensory information. It is not an illness to be cured: autistic people have their own strengths and their own needs, and these vary widely from one person to another, which is why clinicians speak of a spectrum.
Many adults are only identified late, after years of feeling different without knowing why. This is especially common among women, people who learned to mask their traits, and people whose difficulties were put down to anxiety, depression or personality. Living abroad, in a new language and a new culture, can make these challenges more visible: unfamiliar social codes, noise, paperwork and the loss of established routines all demand extra energy.
On this page you will find an overview of autism in adults, common signs, what therapy can offer, and therapists from our network who work with autistic clients, in person or online.
Common signs of autism in adults
- Social communication that feels tiring or confusing: implicit rules, small talk, reading intentions or tone of voice
- A strong need for predictability, routines and clear plans; unexpected changes can be very stressful
- Sensory sensitivity (or under-sensitivity) to noise, light, smells, textures or crowds
- Deep, focused interests and a detailed, systematic way of thinking
- Masking or camouflaging: copying others to fit in, followed by exhaustion
- Shutdowns, meltdowns or autistic burnout after long periods of overload
- Frequent co-occurring difficulties such as anxiety, low mood, sleep problems or ADHD traits
No single sign is enough to suggest autism, and many people show some of these traits without being autistic. Only a qualified professional can carry out a diagnostic assessment.
Causes and contributing factors
Autism has a strong genetic component and comes from differences in brain development that are present from early childhood. It is not caused by parenting, vaccines or personal weakness. What changes over a lifetime is the level of support a person needs, and that depends a lot on the environment: demands at work or in studies, sensory conditions, social expectations, stress and how well the people around understand autism.
- Neurodevelopmental and genetic factors
- High demands with little support or adaptation
- Long-term masking and repeated overload
- Major transitions: moving country, a new job, a breakup, becoming a parent
How therapy can help autistic adults
Therapy does not aim to make anyone less autistic. A neurodiversity-affirming therapist helps you understand how your mind works, put words on past experiences and build a life that respects your needs. The work often focuses on:
- Understanding your profile after a diagnosis, or while you are considering an assessment
- Reducing anxiety, low mood and the effects of burnout
- Recognising sensory triggers and the early signs of overload
- Expressing your needs at work, in relationships and with family
- Reducing masking where it is safe to do so, and rebuilding self-esteem
- Coping with change, including settling into a new country
Therapy approaches that can help
- Autism-informed psychotherapy and counselling: sessions adapted to your communication style, with a clear structure and explicit questions
- Cognitive behavioural therapy (CBT) adapted for autism: often used for anxiety, rumination and low mood
- Psychoeducation: understanding autism, sensory processing and energy management
- Acceptance and commitment therapy (ACT) and mindfulness-based approaches, adapted to sensory needs
- Couples or family sessions, to help partners and relatives understand each other better
Sessions can take place online, which many autistic clients find easier: no travel, a familiar setting and fewer sensory demands. Our therapists work in several languages, so you can speak in the language you feel most at ease in.

Practical strategies for everyday life
- Plan recovery time after social or sensory-heavy activities
- Use tools that reduce overload: noise-cancelling headphones, sunglasses, quiet spaces
- Write things down: checklists, visual schedules, scripts for difficult conversations
- Prepare for change: visit new places in advance, ask for an agenda before meetings
- Connect with other autistic adults and trusted communities
When to seek help
Consider reaching out if you are exhausted or often overwhelmed, or if anxiety, low mood or burnout affect your work, studies, relationships or sleep. Talking to a therapist is also useful if you think you may be autistic and want to explore it before or after an assessment. A formal diagnosis is made by specialised clinicians (psychiatrists or psychologists trained in autism assessment); your therapist can tell you about the options in your country.
If you feel unsafe or at immediate risk of harm, contact local emergency services or a crisis hotline right away.
