Autism Spectrum Disorder in Adults
Autism Spectrum Disorder is not just a "child diagnosis" but a neurodevelopmental condition that can persist throughout the lifespan. A large clinical review describes ASD as a disorder of social communication and interaction, as well as restricted, repetitive patterns of behavior and interests. For adults, this review indicates a prevalence of about 2.2 %. At the same time, there is still no single laboratory value or biomarker that could confirm the diagnosis; careful clinical assessment remains crucial [1].
In adulthood, ASD often presents less in the classic picture from pediatric medicine, but rather through persistent difficulties in social reciprocity, misunderstandings in communication, sensory overload, a strong need for predictability, and exhaustion in social or professional situations. For this reason, the diagnosis in adults is often made late. It is important for those affected to know: a late diagnosis does not mean that the symptoms are "new," but often that they have not been properly categorized for a long time [1].
From a care perspective, ASD is also relevant in adulthood. A German study from specialized outpatient clinics showed an average annual healthcare cost burden of 3,287 euros per person. The largest cost components were attributed to psychiatric inpatient treatments (19.8 %), pharmacotherapy (11.1 %)and occupational therapy (11.1 %). The authors assess the health-related costs as being in a range comparable to severe mental illnesses such as schizophrenia [2].
This makes it clear: ASD in adulthood is not only a diagnostic issue but also a care topic. When autism is recognized late, burdens, misdiagnoses, or unnecessarily long diagnostic pathways often increase. Structured diagnostics, autism-sensitive care, and a realistic view of everyday relevant limitations as well as individual strengths are all the more important [1][2].
Conclusion
Autism Spectrum Disorder in adulthood is clinically well-documented and associated with significant burdens in daily life for many affected individuals. Current evidence shows that sensible, precise diagnostics and care tailored to the needs of adults are crucial. At the same time, ASD is also relevant to the healthcare system because the utilization of services and the associated costs can be significantly higher [1][2].
