A Proteomics Investigation of Salivary Profiles as Potential Biomarkers for Autism Spectrum Disorder (ASD).

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder that affects approximately 1/68 children, with a more recent study suggesting numbers as high as 1/36. According to Diagnostic and Statistical Manual of Mental Disorders, the etiology of ASD is unknown and diagnosis of this disorder is behavioral. There is currently no biomarker signature for ASD, however, identifying a biomarker signature is crucial as it would aid in diagnosis, identifying treatment targets, monitoring treatments, and identifying the etiology of the disorder.

Mass Spectrometry for the Study of Autism and Neurodevelopmental Disorders.

Mass spectrometry (MS) has been increasingly used to study central nervous system (CNS) disorders, including autism spectrum disorders (ASDs). The first studies of ASD using MS focused on the identification of external toxins, but current research is more directed at understanding endogenous protein changes that occur in ASD (ASD proteomics). This chapter focuses on how MS has been used to study ASDs, with particular focus on proteomic analysis.

Comparative two-dimensional polyacrylamide gel electrophoresis of the salivary proteome of children with autism spectrum disorder.

In the last decades, prevalence of autism spectrum disorder (ASD) has been on the rise. However, clear aetiology is still elusive and improvements in early diagnosis are needed. To uncover possible biomarkers present in ASD, we used two-dimensional polyacrylamide gel electrophoresis and nanoliquid chromatography-tandem mass spectrometry (nanoLC-MS/MS), to compare salivary proteome profiling of children with ASD and controls.

Salivary proteomics and biomarkers in neurology and psychiatry.

Biomarkers are greatly needed in the fields of neurology and psychiatry, to provide objective and earlier diagnoses of CNS conditions. Proteomics and other omics MS-based technologies are tools currently being utilized in much recent CNS research. Saliva is an interesting alternative biomaterial for the proteomic study of CNS disorders, with several advantages.

A Pilot Proteomic Analysis of Salivary Biomarkers in Autism Spectrum Disorder.

Autism spectrum disorder (ASD) prevalence is increasing, with current estimates at 1/68-1/50 individuals diagnosed with an ASD. Diagnosis is based on behavioral assessments. Early diagnosis and intervention is known to greatly improve functional outcomes in people with ASD.

Treating clients with Asperger's syndrome and autism.

Asperger's syndrome (AS) is a form of autism spectrum disorder (ASD) affecting many individuals today. Although neurobiological correlates for AS have been identified, like many ASDs, AS is not completely understood. AS as a distinct disorder is also not universally accepted and in the DSM-5 AS is not considered a separate nosological entity.

Mass spectrometry as a tool for studying autism spectrum disorder.

Autism spectrum disorders (ASDs) are increasing in incidence but have an incompletely understood etiology. Tools for uncovering clues to the cause of ASDs and means for diagnoses are valuable to the field. Mass Spectrometry (MS) has been a useful method for evaluating differences between individuals with ASDs versus matched controls.

Using versions of the trail making test as alternate forms.

Alternate forms of neuropsychological instruments are often made parallel by developing tests with similar numbers of items, formats, and psychometric properties. The present study offers an alternative approach by examining three different trail-making tests that could potentially be used as alternate forms. Over a 3-week period, the Trail Making Test of the Delis-Kaplan Executive Functioning System (DK-TMT), Comprehensive Trail Making Test (CTMT), and Connections Task (CT) were individually administered to 154 undergraduate psychology students in each of six possible orders.

Three trail making tests for use in neuropsychological assessments with brief intertest intervals.

Practice effects in serial neuropsychological assessment have led to the use of alternate forms to measure change in cognitive functioning. The construct validity of three variants of the Trail Making Test was explored over a 3-week period in a sample of 158 undergraduate students. Using confirmatory factor analysis, a two-factor (sequencing-shifting) model was identified to best represent the data.

Evidence of practice effects in variants of the Trail Making Test during serial assessment.

Practice effects often obscure detection of meaningful intraindividual cognitive change in serial assessment. The Trail Making Test and four of its variants (i.e.
