“…Relationships have been found between sleep problems in children with ASD and increased rates of overactivity (Hoshino, Watanabe, Yashima, Kaneko & Kumashiro, 1984), disruptive behavior (Patzold, Richdale & Tonge, 1998), communication difficulties (Segawa, Katoh, Katoh & Nomura, 1992), social difficulties (Segawa et al, 1992) and difficulties with breaking routines (Segawa et al, 1992) (as cited in Schreck, Mulick & Smith, 2004).
