“…In this case, too, the available evidence suggests that at least some types of OCD have developmental antecedents. The evidence for these developmental alterations has been summarized in recent reviews (Poletti et al, 2022a ) and includes altered cortical and white matter development in early-onset OCD (Li et al, 2021 ; Park et al, 2022 ), functional alterations in cortico-striato-thalamic circuits in childhood OCD (Huyser et al, 2009 ; Liu et al, 2016 ), a higher frequency of neurological soft signs in OCD patients with poor insight or comorbid tics (Karadag et al, 2011 ; Ekinci and Ekinci, 2020 ), subtle alterations in facial morphology in early-onset OCD (Wang et al, 2021 ), and associations between OCD and events that could alter brain development either pre- or perinatally (Vasconcelos et al, 2007 ) or in early childhood (Barzilay et al, 2019 ; Wislocki et al, 2022 ).…”
