Abstract
Background: In recent years, there has been an emerging interest in the overlap
between schizophrenia and autism. The co-occurrence between these two disorders may be
seen not only at a diagnostic level but also as the presence of autistic traits in schizophrenia.
There has been a rapid rise in the number of studies focusing on autistic traits in schizophrenia
and their clinical associations.
Objective: Here, we provide a review that summarizes the current findings and highlights
gaps that may be addressed by future research.
Results: Higher levels of autistic traits have been associated with earlier age of onset, longer
duration of illness, resistance to treatment, and more severe cognitive deficit. However, regarding
social cognition and psychosocial functioning, the findings are mixed.
Conclusion: Patients with prominent autistic traits seem to be more affected. The effect of
autistic traits on social cognition and psychosocial functioning remains unclear, as does their
relationship with negative symptoms. Therefore, longitudinal studies are highly needed.
Keywords:
Schizophrenia, autistic traits, autism, autistic symptoms, diametric model, social cognition.
