What ASD is in adults
ASD is a neurodevelopmental condition marked by differences in communication and social interaction, restricted or repetitive interests and behaviors, and sensory sensitivities. Intensity varies widely. Many adults, especially those with preserved language and intelligence, went undiagnosed as children and seek assessment after years of exhausting effort to adapt.
Signs and associated conditions
- Difficulty understanding unspoken social rules and keeping up small talk
- Preference for routines and strong discomfort with change
- Highly focused interests
- Sensitivity to sounds, lights, textures or smells
- Exhaustion after social interaction
- Anxiety, depression, insomnia, irritability and, in some cases, ADHD
How the assessment works
The psychiatrist reconstructs developmental history from childhood, with input from relatives when possible, assesses current functioning and looks for associated conditions and look-alike diagnoses such as social anxiety and ADHD. Neuropsychological and other professional assessments can complement it.
Treatment
ASD itself is not something to be “cured”. Psychiatric care focuses on:
- Treating associated conditions, such as anxiety, depression, insomnia and irritability, with psychotherapy and, when indicated, medication
- Guidance for the patient and family about autistic functioning
- Coordinating with therapies and adjustments at work and in studies
When to see a psychiatrist
When there is distress from anxiety, depression, meltdowns, insomnia or exhaustion, or when a suspicion of ASD has never been clarified and would help understand one’s own story.
Follow-up at the practice
