The book, “Autism: A Neurodevelopmental Journey from Genes to Behaviour” reflects the wide range of research being conducted into the aetiology, pathogenesis, clinical characteristics, and intervention in autism. While individual chapters cover alterations in genes, neurochemicals, protein complexes, receptors, synaptic connections etc. that contribute to altered neuronal development, together they convey the story of a neurodevelopmental journey that has lost its way and is aberrant in connectivity. In this regard, Dr. Dafna Ben Bashat discusses abnormal developmental trajectories of White Matter (WM) in autism and suggests that disturbed, abnormal and disorganized inter‐ and intra–cortical connections are one of the core issues in autism, resulting in poorly synchronized and weakly responsive networks, which in turn lead to abnormal cognitive and neurological functioning. While MRI studies have revealed impaired connectivity, and increased brain volume especially early in life, DTI can detect microstructural changes that might help to reveal the neurobiology underpinning autism such as accelerated‐myelination at a young age. In the chapter GABAergic dysfunction in autism and epilepsy, Prof. Yuri Bozzi and colleagues explore the role of GABAergic neurons and circuits in autism and review the genetic, cellular, anatomical and neurophysiological studies that support the hypothesis that the imbalance between excitation and inhibition resulting from neurodevelopmental defects in GABAergic circuitry might represent a common cause for autism and epilepsy.
Following this theme, Prof. Ricardo Miledi and colleagues in their chapter “GABA and Glutamate Receptors of the Autistic Brain” argue that autism is a developmental synaptic disorder that affects the processing  of behavioural relevant information.
Given that GABAergic and glutamatergic synapses appear to be convergent nodes of genetic, epigenetic, and probably environmental factors causing the autistic phenotype, they propose that GABA and glutamate receptors may form important targets for pharmacological interventions. In the next chapter Dr. Dayan Goodenowe further elaborates the biochemical basis of autistic behavior focusing on glutamate and mitochondrial toxicity with suggestions for dietary and pharmacological therapies.
Here mitochondrial dysfunction is implicated in findings such as abnormal brain growth, seizures, gender bias, and selective autistic pathology involving chronic microglial activation as well as “immunoexcitotoxicity” by glutamate. Serotonergic neurotransmission in autism is the focus of a chapter by Dr. Yoshihiro Takeuchi from
Japan while Prof. Susan Masino and colleagues continue this theme by reviewing the actions of Adenosine in the central nervous system, with multiple implications for autism, and the potential for developing new evidence‐based therapies. The chapter by Dr. Rene Anand et al using postmortem, genetic, functional, and molecular neurobiological methodologies discuss a rationale that neuronal nicotinic acetylcholine receptor (nAChR) alterations are biomarkers for autism and that specific nAChRs subtypes are likely to be useful therapeutic targets for the treatment of core deficits.
With all the recent attention on the genetic advances, a number of chapters cover gene effects as well as the environmental modulation of these effects. For example, Dr. Abdullah Alqallaf presents an overview for the analysis of genetic variations in the form of DNA copy number changes and suggests that autism is associated with an increased amount of copy number alteration in unstable segments of the genome and that combinations of copy number variations could provide the basis for discriminating autistic and typically developing groups and potentially identifying distinct subgroups within the phenotypic heterogeneity of autism. The chapter “Genome‐wide Association Studies of Copy Number Variation in Autism” by Prof. Yeun‐Jun Chung reviews the current data on GWAS and argue that the integration of the GWAS data with other resources such as improved bio‐imaging, personal wholegenome sequencing, gene‐environmental interaction and metagenome analysis data will enable us to get a more comprehensive insight to designing future personalized care of autism. The focus of the chapter by Prof. Haruhiro Higashida et al is the finding of a missense mutation in CD38 in three autism pedigrees with a proposal that the CD38 W140 allele could be a risk factor for at least one form of autism by abrogating oxytocin function. On a related topic, Prof. Neumann Inga discusses brain oxytocin as a main regulator of prosocial behaviour and its role in autism.
Although much progress has been made in the recent past in identifying some of the genes that play a crucial role in autism, significant research has also focused on environmental and epigenetic factors involved in the genesis of the disorder. In the chapter “Environmental Factors in the Aetiology of Autism and Lessons from Animals Prenatally Exposed to Valproic Acid”, Dr. Tomasz Schneider and colleagues use rodent models to clarify complex relationships between genetic, behavioural and environmental variables to better understand and potentially cure autism.
Environmentally induced oxidative stress is the focus of the chapter by Prof. Elizabeth Sajdel‐Sulkowska. She discusses disruption of brain thyroid hormone homeostasis with special emphasis on the developmental impact of environmental toxicants, such as herbicides, polychlorinated biphenyls (PCBs), bisphenol A (BPA) and organic mercury compounds that interfere with the thyroid hormone as a possible factor contributing to autistic pathology .....
