Co-occurring Autism and Thought Disorders
Bridges and barriers: exploring the historical conflation, clinical divergence, and biological mirror-phenotypes of Autism Spectrum Disorder and Schizophrenia.
The history of ASD and SCZ is a century-long journey from total diagnostic conflation to strict empirical separation. Initially coined by Eugen Bleuler to describe a symptom of schizophrenia, "autism" has evolved from a psychoanalytic defense mechanism into a recognized neurodevelopmental identity. This section traces the shift from viewing autism as "childhood schizophrenia" to the modern neurodiversity paradigm.
