Our latest book was published electronically and can be downloaded free of charge from Frontiers. The title of the book is Comorbidity and Autism Spectrum Disorder. I edited the same along with my wife, Richard Frye and Christopher Gillberg. The book was based on a special research theme sponsored by Frontiers. It consists of 32 chapters (articles), contributed by 283 authors, focusing on recent understanding regarding the impact and management of comorbidities associated with autism spectrum disorder (ASD). The book sought to answer questions such as: Are standard screening instruments capable of delineating the full range of impairment in ASD without considering comorbidities? Given the difficulties in communication for many ASD patients, what red flags point toward the presence of comorbidities? How do comorbid conditions relate to maladaptive behaviors? How do health care providers grapple with the juxtaposition of intellectual disability (ID), non-verbal clinical care, and comorbidities in ASD? This book attempted to answer these and other questions while raising awareness on how comorbid conditions increase both mortality and morbidity in ASD.
