The purpose of the present study was therefore to compare the neuropsychological performance of different subtypes of OCD and matched non-clinical controls (NCs) on the Cambridge Automated Neuropsychological Test Battery (CANTAB).<\/jats:p>\n                  <jats:p>Methods: Fifty-nine OCD patients and 59 non-clinical controls completed selected tests from CANTAB examining executive function, visual memory and attentional-set shifting. Depression, anxiety and OCD symptoms were also assessed.<\/jats:p>\n                  <jats:p>Results: From 59 OCD patients, four subtypes were identified: (i) washers; (ii) checkers; (iii) obsessionals; and (iv) mixed symptom profile. Comparisons between washers, checkers, obsessionals and NCs indicated few differences, although checkers were generally found to exhibit poorer performance on spatial working memory, while obsessionals performed poorly on the spatial recognition task. Both checkers and the mixed subgroups showed slowed initial movement on the Stockings of Cambridge planning task and poorer pattern recognition relative to NCs.<\/jats:p>\n                  <jats:p>Conclusion: Overall the results suggested greater impairments in performance on neuropsychological tasks in checkers relative to other subtypes, although the observed effects were small and the conclusions limited by the small subtype samples. Future research will need to account for factors that influence neuropsychological performance in OCD subtypes.<\/jats:p>","DOI":"10.1080\/00048670802653273","type":"journal-article","created":{"date-parts":[[2009,12,7]],"date-time":"2009-12-07T18:34:04Z","timestamp":1260210844000},"page":"216-226","source":"Crossref","is-referenced-by-count":54,"title":["Differences
