Differentiating autism from other handicapping conditions, especially mental retardation, has been a constant problem for public schools. This study investigated the effectiveness of three instruments to discriminate autistic from trainable mentally retarded children. The Autism Screening Instrument for Educational Planning, the Childhood Autism Rating Scale, and the Diagnostic Checklist for Behavior Disturbed Children, Form E-2 were administered to 20 autistic and 20 TMR students. Discriminant analysis was used to determine the best linear combination of scores that would separate the two groups of children. All three instruments were found to separate the two samples of children. However, the CARS and the ASIEP provided for a greater separation of groups.

To assess the utility of the Childhood Autism Rating Scale - Tokyo Version (CARS-TV), its total score was compared among 430 children with DSM-IV per subgroup (i.e. autistic disorder (AD), childhood disintegrative disorder (CDD), Asperger's disorder, and pervasive developmental disorders (PDD) not otherwise specified (PDDNOS)). Values of Cronbach's alpha were 0.91 for the PDD group and 0.89 for the non-PDD mental retardation (MR) group, and 0.93 for both groups combined. The total score was significantly higher in PDD (mean = 30.1, SD = 4.5) than in non-PDD MR (mean = 22.9, SD = 3.3), t(503) = 13.7, P< 0.0001. The cut-off to distinguish PDD from non-PDD MR was 25.5/26, with sensitivity, specificity, positive predictive value and negative predictive value of 0.86, 0.83, 0.97 and 0.50, respectively. The total score differed significantly among the four groups, with CDD and AD being significantly higher than both PDDNOS and Asperger's disorder, PDDNOS being significantly higher than Asperger's disorder and no significant difference between CDD and AD. The cut-off to distinguish AD from PDDNOS was 30/30.5, with sensitivity, specificity, positive predictive value and negative predictive value of 0.71, 0.75, 0.77 and 0.69, respectively. CARS-TV seems to be a useful instrument for differentiating between PDD and non-PDD MR and between AD and PDDNOS, although further replication is needed.

An open prospective clinical study included 25 patients with childhood autism aged from 3 to 8 years (mean age 5 years 11 months). Patients received 2 therapeutic courses (15 intramuscular Cerebrolysin injections of 1.0 ml every other day per course) with 2 months interval and basic antipsychotic therapy using typical neuroleptics in age-adjusted dosages. The duration of the study was 180 days. Significant or very significant improvement was achieved after the 1st Cerebrolysin course in 38% patients, after the 2nd course in more than 50% and to the end of the follow-up (180th day) in 71% of patients. There were no cases of deterioration during the trial. The autism severity as measured by the CARS scale consistently decreased from the day 0 to the day 180--from 37.7 to 32.6 scores, respectively (p < 0.001) in all assessments as compared with the baseline. To the end of the study, the patients demonstrated a significant decrease in mental retardation by 0.2 years. A statistically significant improvement was achieved in cognitive activity, attention during task performing as well as in self-service (by 0.3 years), receptive and expressive speech, cognitive performance and perception (by 0.2 years), fine motor function (by 0.1 years). The combined therapy comprising neuroleptics and Cerebrolysin double course can be recommended for correction of behavioral disorders and cognitive dysfunction in patients with mild moderate and moderate/severe autism.

Hyperserotonemia is the most consistent serotonin-related finding in autism. The basis of this phenomenon, and its relationship to the central serotonergic dysfunction remains unclear. Platelet serotonin level (PSL) in 53 autistic adults and 45 healthy controls was measured. Mean PSL in autistic group (75.7 +/- 37.4 ng/microL) was significantly higher than the control sample (59.2 +/- 16.2 ng/microL) due to a presence of hyperserotonemic subjects which comprised 32% of the patients. PSL of autistic subjects did not correlate with the severity of symptoms, as measured by total CARS score, or the degree of mental retardation. However, significant negative relationship was observed between PSL and speech development, indicating the relationship between the peripheral 5HT concentrations and verbal abilities in autistic subjects.

Asperger syndrome (AS) and autistic disorder are two subtypes of pervasive developmental disorders (PDD), but there has been considerable debate over whether AS and autistic disorder without mental retardation (IQ > or = 70), called high-functioning autism (HFA), are distinct conditions or not. The aim of the present paper was to clarify this issue through a comparison of cognitive function and autistic symptom profiles. Based on the DSM-IV and ICD-10 definitions of language acquisition, 36 age- and IQ-balanced subjects with AS (mean age, 12.8 years; mean full-scale IQ, 98.3) were compared with 37 subjects with HFA (mean age, 12.6 years; mean full-scale IQ, 94.6) on the Japanese version of the Wechsler Intelligence Scales and the Childhood Autism Rating Scale-Tokyo Version (CARS-TV). Compared with the HFA subjects, the AS subjects scored significantly higher on Verbal IQ, Vocabulary, and Comprehension, but scored significantly lower on Coding. Although the total CARS-TV score did not differ significantly between the two groups, AS subjects scored significantly lower (i.e. less abnormal) on Verbal communication and Non-verbal communication than did the HFA subjects. A history of normal language acquisition in early childhood could predict his/her better verbal ability in mid-childhood or later. Autistic cognitive characteristics shared by both AS and HFA subjects appear to support the validity of the current diagnostic classification of PDD.

People with sensory impairments combined with intellectual disabilities show behaviours that are similar to Autism Spectrum Disorder (ASD). The instrument Observation of Autism in people with Sensory and Intellectual Disabilities (OASID) was developed to diagnose ASD in this target group. The current study focuses on the psychometric properties of OASID. Sixty individuals with intellectual disabilities in combination with visual impairments and/or deafblindness participated in this study. The OASID assessment was administered and rated by three independent observers. By means of expert consensus cut-off scores for OASID were created. To determine the concurrent validity OASID was compared with the Pervasive Developmental Disorder for People with Mental Retardation (PDD-MRS) and the Childhood Autism Rating Scale second edition (CARS-2). The intra-rater reliability, the inter-rater reliability, internal consistency and concurrent validity of OASID were good to excellent. Cut-off scores were established based on criteria from the DSM-5. OASID was able to differentiate between four severity levels of ASD.
