Autistic spectrum disorders (ASD) are common neurobehavioral syndromes characterized by deficits in social interactions, impaired communication skills and repetitive stereotypic behaviours expressed by 3 years of age (1). Recent studies of these disorders indicate a strong genetic component but specific aetiologies and pathogeneses are usually unknown (1–3). Concordance for ASD is 90% in identical twins compared to 10% for dizygotic twins and siblings. In recent years the incidence of ASD has… 
Clinical and Molecular Characteristics of Mitochondrial Dysfunction in Autism Spectrum Disorder
Preliminary evidence suggests that the mitochondria may be a fruitful target for treatment and prevention of ASD, and several environmental factors, including toxicants, microbiome metabolites and an oxidized microenvironment are shown to modulate mitochondrial function in ASD tissues.
Mitochondrial dysfunction in autism spectrum disorders: a systematic review and meta-analysis
Evidence supports the notion that mitochondrial dysfunction is associated with autism spectrum disorders, and suggests children with ASD have a spectrum of mitochondrial dysfunction of differing severity.
Mitochondrial Dysfunction in Autism
The evidence about mitochondrial dysfunction in autism is reviewed, including decreased activities and protein expression levels of ETC complexes, mtDNA or nDNA mutations, oxidative stress, and calcium-signaling abnormalities in autism.
The review of most frequently occurring medical disorders related to aetiology of autism and the methods of treatment.
Medical problems of children with autism which may be identified and treated by general practitioners as a review of current medical papers related to Autism Spectrum Disorder are presented, in the context of author's professional experience, based on the medical cases from author's practice.
Can Awareness of Medical Pathophysiology in Autism Lead to Primary Care Autism Prevention Strategies
Given the prevalence of autism for that cohort of 1 in 50 children in the United States, it is important to consider implementing strategies in primary care practice that could potentially modify environmental factors or affect the timing of environmental triggers contributing to autism.
Mitochondrial and ion channel gene alterations in autism.
A case study of a young man with intellectual disability, mitochondrial disorder, epilepsy, autism and psychosis: how did we decide which psychotropic drug to use?
The case study is of a young man with a mitochondrial disorder, secondary sensory impairments, mild intellectual disability, epilepsy and autism spectrum disorder who developed a psychotic illness.
B-Lymphocytes from a Population of Children with Autism Spectrum Disorder and Their Unaffected Siblings Exhibit Hypersensitivity to Thimerosal
Cells hypersensitive to thimerosal also had higher levels of oxidative stress markers, protein carbonyls, and oxidant generation, which suggests certain individuals with a mild mitochondrial defect may be highly susceptible to mitochondrial specific toxins like the vaccine preservativeThimerosal.


Mitochondrial DNA abnormalities and autistic spectrum disorders.
The epidemiology of autism spectrum disorders.
Future epidemiologic research should focus on expanding population-based descriptive data on ASDs, exploring candidate risk factors in large well-designed studies incorporating both genetic and environmental exposure data and addressing possible etiologic heterogeneity in studies that can stratify case groups and consider alternate endophenotypes.

Developmental Regression and Mitochondrial Dysfunction in a Child With Autism
A singleton case of developmental regression and oxidative phosphorylation disorder in a 19-month-old girl is presented and data suggest that further metabolic evaluation is indicated in autistic patients and that defects of oxidativeosphorylation might be prevalent.
Mitochondrial dysfunction in autism spectrum disorders: a population-based study.
Five of 11 patients studied were classified with definite mitochondrial respiratory chain disorder, suggesting that this might be one of the most common disorders associated with autism and warranting further investigation.
Mitochondrial Dysfunction in Patients With Hypotonia, Epilepsy, Autism, and Developmental Delay: HEADD Syndrome
The findings suggest that mitochondrial dysfunction, including extensive abnormalities in specific enzyme activities, mitochondrial structure, and mitochondrial DNA integrity, may be present in children with a clinical constellation including hypotonia, epileptic seizures, autism, and developmental delay.
Genetic influences and infantile autism
A study of a systematically collected sample of 21 pairs of same-sexed twins, one or both of whom had autism as diagnosed by the criteria of Kanner3 and Rutter4, indicates the importance of hereditary influences in the aetiology of autism.

The evidence suggests that the majority, if not all, of the reported rise in incidence and prevalence of autism in pre-school children is due to changes in diagnostic criteria and increasing awareness and recognition of autistic spectrum disorders.
Genetics of austim: complex aetiology for a heterogeneous disorder
The identification of chromosomal abnormalities and Mendelian syndromes among individuals with autism, in conjunction with data from genome screens and candidate-gene studies, has helped to refine the view of the complex genetics that underlies autism spectrum conditions.
