      Sex differences in typical development can provide context for understanding ASD. It has been suggested that ASD could be considered an extreme expression of normal male, compared to female, phenotypic profiles. In this paper, sex-specific M-CHAT scores from N=53,728 18-month old toddlers, including n=185 (32 females) receiving an ASD diagnosis, were examined. Results suggest a nuanced view of the ...

      Schjølberg, Synnve; Shic, Frederick; Volkmar, Fred R.; Nordahl-Hansen, Anders; Stenberg, Nina; Torske, Tonje; Larsen, Kenneth; Riley, Katherine; Sukhodolsky, Denis G.; Leckman, James F.; Chawarska, Katarzyna; Øien, Roald A (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-26)
