As such, the focus on identifying a prodrome over the past 20 years has been on pre-clinical signs or indicators that will be present very early in life, certainly in infancy. A number of novel lines of investigation have been used to this end, including retrospective coding of home videos, prospective population screening and ‘high risk’ sibling studies; as well as the investigation of pre- and peri-natal, brain developmental and other biological factors. Whilst no single prodromal sign is expected to be present in all cases, a picture is emerging of indicative prodromal signs in infancy and initial studies are being undertaken to attempt to ameliorate the early presentation and even ‘prevent’ emergence of the full syndrome. date: 2010-04 date_type: published oa_status: green language: eng primo: open primo_central: open_green full_text_status: public publication: Journal of Child Psychology and Psychiatry volume: 51 number: 4 pagerange: 432-458 pages: 27 refereed: TRUE issn: 0021-9630 citation: Yirmiya, Nurit; Charman, Tony; (2010) The prodrome of autism: early behavioral and biological signs, regression, peri- and post-natal development and genetics.
