Biological Implications of the Overlapping Phenomenon Between Childhood Schizophrenia and Autism Spectrum Disorders-Heterogeneity Approach Rather Than Diagnostic Boundary
An observational study of Schizophrenia and Autism Spectrum Disorder, run by National Taiwan University Hospital.
Trial summary
Complex diseases such as schizophrenia and autism are heterogeneous in clinical presentation and etiology. This high heterogeneity constitutes the challenges for the clinical diagnosis and etiological research, resulting in that the majority of research findings cannot be replicated in the independent samples.

About this study
Complex diseases such as schizophrenia and autism are heterogeneous in clinical presentation and etiology. This high heterogeneity constitutes the challenges for the clinical diagnosis and etiological research, resulting in that the majority of research findings cannot be replicated in the independent samples. For the high comorbid rate between the diagnoses of schizophrenia and autism spectrum disorders (ASD), and the shared neurocognitive deficits, genetic risks, and biological markers between the two disorders, a heterogeneity approach may probably be more promising than to arbitrarily split the two diagnostic categories apart or lump them together for etiological research. In schizophrenia, patients with a very early onset of disease and with preceding neurodevelopmental conditions may imply a different underlying etiology from those with typical onset and without neurodevelopmental conditions. Echoing the evidence that in early onset Parkinson's disease, PARK2 (encoding parkin protein) mutations are successfully reported to be as frequent as 49% with an autosomal-recessive mode of inheritance , representing a specific disease entity of Parkinson's disease. Therefore, it is critical to characterize the clinical phenotypes for this subpopulation of very early onset patients, including their clinical manifestation, disease course, and treatment response, as well as early developmental history and morphological characteristics. These may establish an important base for investigating the etiology and providing adequate clinical care for the heterogeneous syndrome of schizophrenia

What is being measured
The primary outcome is the main question the study is designed to answer.
Positive and Negative Syndrome Scale PANSS
33 item scale composed of 7 positive scale, 7 negative scale, 16 general psychopathology, and 3 aggression risk profile. Range from 0 to 7, higher the score, more severe the symptoms are.
Measured: 3 years
Autism Diagnostic Observation Schedule
interview with subjects. range from 0 to 8, higher the score, worse the autistic symptoms.
Measured: 3 years.
Physical anomalies and craniofacial features
41 qualitative items were used to examine the presence or absence of morphological anomalies and magnitude of anomalies. Minor physical anomalies were rated from 0 to 83, higher the score, greater the anomalies.
Measured: 3 years
Brain structural anatomy with MRI scan
3 Tesla MRI with a 32-channel head coil was used to collect brain imaging of cortical thickness, cortical volume, white matter volume, gyrification. The MRI structural images will be analyzed using FreeSurfer image analysis suite.
Measured: 3 years

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
