Symptom dimensions in OCD and their association with clinical characteristics and comorbid disorders

“…These symptom dimensions have been reported to be temporally (Mataix-Cols et al, 2002) and cross-culturally stable (Matsunaga et al, 2008), with distinct neural correlates (Mataix-Cols et al, 2004) and comorbidity patterns (Hasler et al, 2005). Brain-imaging and genetic studies have also provided preliminary evidence for the biological validity of these dimensions (Gilbert et al, 2008;Hashimoto et al, 2011;van den Heuvel et al, 2009).…”

Endophenotypes of obsessive–compulsive disorder: Current status and future directions

“…A number of neuropsychological studies have reported that OCD symptoms differ in their association with cognitive deficits (e.g., Blom et al, 2011;Hashimoto et al, 2011;Omori et al, 2007). It remains to be determined whether such findings are replicable and whether the abnormalities identified in these studies meet criteria for CEPs, as described earlier in this article.…”
