[Comparison of psychometric and pathopsychological approaches in the assessment of intellectual activity in children and adolescents with progressive forms of schizophrenia].

Objective: To study the intellectual activity of children and adolescents with progressive forms of schizophrenia using quantitative and qualitative diagnostic methods.

Material And Methods: An experimental group consisted of 67 children and adolescents (mean age 11.1±2.

Ribosomal DNA Abundance in the Patient's Genome as a Feasible Marker in Differential Diagnostics of Autism and Childhood-Onset Schizophrenia.

Introduction: Differential diagnostics of early-onset schizophrenia and autism spectrum disorders (ASD) are a problem of child psychiatry. The prognosis and relevant treatment are to a large degree determined by the correctness of diagnosis. We found earlier that leucocyte DNA of adult schizophrenia patients contained significantly larger copy numbers of ribosomal repeats (rDNA) coding for rRNA, than DNA of mentally healthy controls.

[Paired and partial correlations of immune parameters of neuro-immuno-test and coagulation parameters of thrombodynamics test in children with children's autism].

Objective: To reveal paired and partial correlations of values of neuro-immuno-test and thrombodynamics test in children with childhood autism and schizophrenia in childhood in a state of exacerbation.

Material And Methods: The study used a database of children with childhood autism, obtained by us in 2028-2019. The study included 46 patients with childhood autism (CA) aged 2 to 13 years: median age [Q1; Q3] - 5 years [4; 7], 10 girls (22%) and 36 boys (78%)).

Epidemiological Screening for the Risk of Mental, Behavioral and Developmental Disorders, Including Autism, in Early Childhood: Data for Russia 2017-2019.

We aimed to screen children aged 18-48 months in the general population of nine Russian regions for risk of mental, behavioral and developmental disorders (MBDDs) including autism spectrum disorders (ASD) using an original screening tool. The prevalence of the risk for MBDDs is 1307:10,000 (13.07%), the prevalence of clinically verified cases of MBDDs is 151:10,000 (1.

Impact on the Risk and Severity of Childhood Onset Schizophrenia of Schizophrenia Risk Genetic Variants at the DRD2 and ZNF804A Loci.

The study explored whether schizophrenia risk alleles of the DRD2 rs2514218 and ZNF804A rs1344706 polymorphisms also influenced the risk and severity of childhood-onset schizophrenia (COS) and differentiated it from autism spectrum disorders (ASD). We compared 75 children with COS to 75 children with ASD, 150 patients with adult-onset schizophrenia and 150 healthy individuals. Frequency of the DRD2 T-allele, assumed to be protective against schizophrenia overall, was higher in COS compared to adult-onset schizophrenia and healthy controls.
